Huber of the Canadian Forest Service in Ottawa, who spent years reviewing and measuring the tiny Mymarid, Anaphes sp., an important group for biological control and systematics. This group is extremely difficult to work with due to its tiny size in spite of the many optical tools available. I am sure you will find that the clarity of the plates of these seldom-seen Anaphes, will add a new dimension to your viewing pleasure of insects. 7 It is not only the tiny Anaphes sp. that has gone unnoticed, but much larger Apids and Orthopteroids are showing up as new Canadian records, when collections are examined more closely by dedicated individuals. The continued work of T. Romakova at the Royal Ontario Museum in Toronto, revising the bees of Ontario, reports seven new records of Apids for Canada, while S. Marshall’s group of the Systematics Laboratory at the University of Guelph, reports seven records of Orthoptera for Canada and one new record for Ontario. Dealing with insecticide resistance is a long-standing problem in apple orchards everywhere. D. Pree’s group of the Agriculture and Agri-Food Canada laboratory in Vineland presents a profile of the dynamics of insecticide resistance in some Ontario orchards over three years. This study demonstrates how insecticides from different chemical groups interact with one another, and suggests how to reduce insecticide resistance in apple orchards. Ontario is also known for its wine and it is fitting that JESO presents works on vineyard pests. In 2001, Ontario vineyards became infested with aphids and the multicoloured Asian lady beetle soon followed, which created a new problem for the wine industry. If large populations of the beetle are present in the vineyards when the grapes are harvested, the beetles get crushed along with the grapes, tainting the wine. D. Pree’s group developed a protocol to provide an immediate or short-term response to the new problem. I thank Martin Damus again for his continued service to the Society in providing the cover drawing of the Anaphes laying an egg. Thanks to Karen Jamieson and Mark Primavera for the technical layout of this volume. Our associate editors along with reviewers from across Canada and the United States provided valuable feedback to the authors. Finally, we are already working on volume 136 of JESO and we would be pleased to read your work and consider it for publication. Yves Prévost Yves.

Most of the biological literature on Mymaridae involves species of only two genera, Anaphes Haliday and Anagrus Haliday, because they are important for the biological control of pests of several major crops (Huber 1992, Chiappini et a/. 1996). About 235 species of Anaphes have been described but few have host records associated with them. Chrysomelidae or Curculionidae are the most commonly reported hosts, but some Anaphes species have been reared from other families in Coleoptera, Diptera, Hemiptera or Hymenoptera (Symphyta). The several taxonomic treatments of Anaphes have resulted in a somewhat complicated nomenclatural history as discussed by Debauche (1948), Annecke and Doutt (1961), Schauff (1984a), and Huber (1992). Huber (1992) divided the genus into two subgenera, Anaphes (Anaphes) and Anaphes (Yungaburra), based on differences in male antennae. Males of species of Anaphes (Yungaburra) have each of the 11 flagellomeres bearing at least one longitudinal sensillum whereas males of Anaphes s.s. apparently have only 10 flagellomeres because FI, is extremely reduced and lacks longitudinal sensilla. Huber (1992) subdivided Anaphes (Yungaburra) into three species groups (the amplipennis and nitens groups, and an unnamed group) and Anaphess.s. into two species groups, the fuscipennis group and the crassicornis group, based on the number of claval segments in the female antennae. Species of the crassicornis group are separated by their two-segmented clava from species of the fuscipennis group, which have a one-segmented (entire) clava. Huber (1992) reviewed the nine described species of the fuscipennis group in North America; the described species of the crassicornis group in North America are reviewed here. Species in the latter group have previously been classified either in their own genus, Patasson (e.g. Kryger 1934), or as a subgenus of Anaphes (e.g. Debauche 1948). In the Nearctic region, the crassicornis group includes 13 nominal species: nine catalogued under Patasson by Burks (1979), A. pallipes (Ashmead) catalogued under Anaphes by Burks (1979) and transferred to the crassicornis group by Huber (1992), and three additional species described by Huber in Huber et al. (1997). Eight of the species [A. calendrae (Gahan), A. conotracheli Girault, A. cotei Huber, A. diana (Girault), A. /una (Girault), A. listronoti Huber, A. pullicrurus Girault, and A. victus Huber] have been reared from economically important pests. Anaphes luna was imported from Europe for biological control and released in Utah where it successfully established and spread. Anaphes diana was also imported from Europe and was released in Delaware, Idaho and Kentucky but field establishment is uncertain (Yeargan 1985). The remaining four species [A. brunneus (Doutt), A. gerissophaga (Doutt), A. longiclava (Doutt), and A. confertus (Doutt)] are known from only one or a few specimens, either reared from hosts of no economic importance or not reared and without known hosts. Despite their economic importance and abundance, the taxonomy of crassicornis- group species is difficult and most of the species cannot easily be identified. As a first step to try to resolve the problem of species identifications, the described species occuring in the Nearctic region are keyed and redescribed, and their type specimens are illustrated. The total number of Anaphes species occuring in America north of Mexico can only be guessed at. Only three collections (CNCI, UCRC, USNM, acronyms explained below) have considerable numbers of Anaphes specimens (several thousand individuals in total) and most would have to be slide mounted for detailed studied before a reasonable estimate could be made. Based on my current knowledge of the genus I think the number of North American morphospecies is perhaps around two or three times the number already described, i.e. 40-50 species in total, more or less divided equally between the two species groups. Comparison with Journal of the Entomological Society of Ontario Volume 135, 2004 other zoogeographical regions is not helpful for determining the size of the North American fauna because none of their faunas (except Europe) have been studied systematically. The European situation presents a major problem because of the typological species concept used by the single author who described most of the approximately 160 nominal species from relatively few localities. Most of his species are likely synonyms of one another. Materials and Methods Morphological terms used and measurements, given in micrometers (um), are as described in Huber (1992) and Gibson (1997). All the features mentioned in the species diagnoses must be taken into account when comparing a specimen; if only some features match and others do not it is likely that the specimen does not belong to the species in question. Descriptions include the mean and, in parentheses, the range and number of specimens measured. Primary types were measured separately (Table I). Their measurements are not included in the species statistics, thus permitting independent comparison with non-type material. Where possible, qualitative features were used to identify species, but there seem to be few such features in species of Anaphes so considerable reliance was placed on measurements and ratios. The relative length of tarsomere 1 to 2 has not been used before. Using slide-mounted specimens, each tarsomere is measured from its base to the proximal point of insertion of the next tarsomere (Fig. 34). The apical tarsomere is measured to the point of insertion of the pretarsus. The pretarsus is not included in total tarsal length. The ‘ovipositor length’ (Fig. 41) was measured from the basal loop to the apex of the sheaths instead of to the apex of the ovipositor itself because the ovipositor apex is not always clearly visible when it is hidden by the sheaths. The true ovipositor length is acutally slightly less than the length measured from the apex of the sheaths. For measurements to be exact, structures being measured must have both end-points in focus at the same time. This was not the case for some measurements because of the poor quality of most of the slide-mounted specimens available for study. Thus a certain amount of unavoidable inaccuracy occurs that increases the range for a given structure. In particular, absolute body measurements taken from slide-mounted specimens are somewhat inaccurate because the specimens usually had the head collapsed or mounted obliquely. Approximate head length was added to the separate measurements of mesosoma and metasoma to obtain total body length. Because most specimens, either representing different species or the same species reared from different hosts, were mounted in the same way, comparison of measurement among specimens shows the relative changes in size reasonably well. Because of small sample sizes (less than 30) the sample standard deviation, which is slightly larger than the standard deviation, was calculated. Species limits based on ranges and deviations are thus somewhat broadened and greater overlap among the measurements of different species occurs. Until many more, well prepared slide-mounted specimens of each species become available for measurement the limits of variation cannot be defined more accurately. Photographs of wings and antennae were made with a digital camera attached to a compound microscope. The species of the crassicornis group are so similar that long descriptions are simply repetitious. The descriptions consist mainly of measurements and, together with the diagnoses, should suffice to recognize a particular species. Abbreviations used are: Fl,-Fl, = funicle segment 1 to 6, FWL/FWW = forewing length/forewing width, LMC = longest marginal cilia of forewing or hind wing.

Variability in Anaphes species Females are the most commonly collected sex and the only known sex for some species. Therefore, mymarid taxonomy is based almost exclusively on females, and only females can be identified fairly reliably using morphological features alone. Males are usually ignored unless they can be definitely associated with corresponding females. Sexual variation is therefore not a problem to consider in mymarid taxonomy. Another kind of variation occurs when individuals of a gregarious species, e.g. A. calendrae, presumably obtain varying amounts of nutrients from the single egg in which they develop, resulting in overall size differences. The source of variation with the greatest influence in modifying morphology appears to be the host. Different host species may cause qualitative as well as quantitative morphological changes in their parasitoids. For example, in A. io/e Girault not only are specimens reared from smaller hosts smaller in size but loss of longitudinal sensilla on Fl, occurs, with a concomitant change it its proportions (Huber and Rajakulendran 1988). Evidence is presented below that two nominal Anaphes spp., A. pallipes and A. conotracheli, reared from Cylindrocopturus adspersus LeConte and Conotrachelus spp., respectively, may be a single species. The differences between these two putative species are similar to those found for A. dole reared from its different hosts. If the length of a structure varies continuously between two extremes (e.g. A. calendrae, as described below) depending on host size, this can be more easily taken into account when characterizing the limits of variation in a species than a disjunction in qualitative features. In the later case, one may easily, but incorrectly, propose two or more species (as was probably done by some authors working on the European fauna) unless the biology and host range are known or crossing experiments can be performed to demonstrate conspecificity. Conversely, morphologically almost identical species that are biologically different are known to occur, e.g. A. sordidatus Huber and A. listronoti Huber (Huber et al. 1997). The lack of host information and difficulty of doing crossing experiments with most described Anaphes species greatly hinders a proper understanding of species limits in the genus.

Occipital suture short, angled inwards towards dorsal margin of occipital foramen (as in Figs. 31, 32); forewing clear on posterior margin to mid-point of wing apex (Fig. 16); Fl, at least 4.3 times as long as apical width (Fig. 1). Anaphes brunneus, A. pallipes, A. conotracheli and the Palearctic A. pectoralis are all closely related based on the short, angled occipital suture and the clear hind margin of the forewing. They also share these two features with A. ole of the fuscipennis species group. Anaphes brunneus differs from A. pallipes and A. conotracheli by its longer F,, the longest funicle segment. Except for the antennal and ovipositor proportions, specimens of A. brunneus and those of A. conotracheli appear to be identical so the species may be synonymous. More, preferably reared, specimens from hosts in western North America are required so variation can be assessed adequately to determine if the species are really the same. Description. Female.

Anaphes calendrae is a gregarious parasitoid of Sphenophorus species (Curculionidae: Rhynchophorinae), commonly known as billbugs (Vaurie 1951). Up to nine individuals have been reared from a single host egg. Usually seven larvae (one male and six females) develop per host egg and there are four to seven broods per year (Satterthwait 1931). The original series from which laboratory rearings were initiated was field collected at Kirkwood [Station] from the egg of S. parvulus (Gyllenhal) on timothy and from eggs of S. 2minimus Hart. The species was reared through several generations on different Sphenophorus hosts at the Webster Groves field laboratory. Satterthwait (1931) found that A. calendrae destroyed 75% of S. minimus and S. parvulus eggs in white bent grass, Agrostis alba. Other field collected hosts were S. callosus (Gyllenhal) and S. destructor Chittenden. Under laboratory conditions, S. costipennis Horn, S. australis Chittenden, S. maidis Chittenden, S. necydaloides Chittenden, and S. venatus (Say) were successfully parasitized (Vaurie 1951). Anaphes calendrae was introduced into Hawaii in an attempt to control Sphenophorus cariosus (Olivier) (Beardsley 2000). Under insectary conditions, A. calendrae was reared on S. cariosus and S. venatus vestitus Chittenden and it is presumed that these hosts are also attacked in the field (Beardsley 2000). Over 74,000 specimens from Florida and Missouri were successfully propagated for release in Hawaii (Anonymous 1970). A prior attempt to establish A. calendrae against the New Guinea sugarcane weevil, Rabdocnemis obscura Boisduval, in Hawaii failed so this species is probably not a host, despite being cited as such by Thompson (1958). Nevertheless, it is capable of parasitizing R. obscura eggs in the laboratory (Bianchi 1964). Anaphes confertus Doutt (Figs. 3, 18, 37) Anaphoidea conferta Doutt, 1949: 155 (original description).

The specimen has the head and antennae missing. The date of capture of this specimen was incorrectly cited by Girault (1905) as v.16. Clearly, he mixed up the dates and places of capture for the specimens from Arundel, MD, and Tryon, NC (collected on 20.v). PARATYPES. One female and 5 males under one coverslip on slide labelled 1.“Anaphes species on eggs Cono. nenuphar Ft. Valley, Ga.

I treat this as a valid holotype designation according to article 73.1.1 of the ICNZ (1999), particularly because only one 13 Journal of the Entomological Society of Ontario Volume 135, 2004 specimen is labelled “type” and several (but not all) the others mentioned by Girault are labelled as paratypes. I slide-mounted three (2% and 1c*) of the original point-mounted specimens and used one paratype from Fort Valley, Georgia, for the measurements given in Table I. Diagnosis. Occipital suture angled inwards towards dorsal margin of occipital foramen (Fig. 32); Fl,-Fl, usually each with 2 longitudinal sensilla; forewing with part of posterior margin hyaline medially, preceded and followed by a narrow dark margin and another short, clear area on posteroapical curve almost to apex that abruptly changes to a dark margin along anteroapical curve (Fig. 19); ovipositor extending forward under mesosoma at least to the apex of forecoxa and basal loop very tight, with dorsal arm almost parallel to ventral arm (Fig. 38). Among the described Nearctic species of the crassicornis group the oblique occipital suture and dark and light border of the posterior margin of the forewing distinguish A. brunneus, A. conotracheli, and A, pallipes from the remaining described species, which all have a straight occipital suture and uniformly dark posterior margin of the forewing. The only feature that apparently distinguishes A. conotracheli from A. pallipes is the presence in A. conotracheli of | or, usually, 2 longitudinal sensilla on Fl, (none in A. pallipes). Anaphes pallipes is also smaller than A. conotracheli. The only features that distinguish A. conotracheli from A. brunneus are the relatively shorter and broader Fl,, with a ratio of at most 3.3 (at least 4.4 in A. brunneus), and the ovipositor/hind tibia ratio of at least 1.8 (1.62 in A. brunneus). Description. Female. Co/our (from four point-mounted paratypes). Body brown. Legs almost white except coxae, femora in middle, and tarsomere 4 light brown. Forewing (Fig. 19) with posterior margin clear to apex of wing or at least distinctly lighter brown than anterior margin, except for a short brown section subapically. Body length. 536 jum (460-620, n= 11, from slide-mounted specimens from GA, MD, VA). Head. Width 221 (189-238, n=12). Occipital suture short, angled inwards towards dorsal margin of occipital foramen (Fig. 32) Antenna. \nner surface of scape and pedicel with distinct, oblique cross striations. Fl,, Fl, and Fl each with 2 longitudinal sensilla, Fl, usually with 2 sensilla (Fig. 4) but sometimes (one third of the specimens measured) with | sensillum. Measurements are given in-Table XIV. Mesosoma, Pronotum and mesonotum with short, inconspicuous setae. Wings. Forewing length 661 (592-704, n=14), width 141 (124-154), FWL/FWW 4.70 (4.43- 5.15), LMC 127 (108-140); marginal space 107 (80-143), medial space triangular; cubital line of setae closest to posterior margin of wing near retinacular seta, then diverging away until separated by at least one setal length from posterior margin. Hind wing length 644 (633-671, n=10), width 29 (24-32), with 0-4 (usually only with 1) microtrichia medially on blade in apical half, LMC 106 (90-115). Legs. Foretibia with 8-11 sensilla chaetica. Hind tarsomere 0.76 (0.70-0.82, n=10) times as long as hind tarsomere 2. Metasoma. Ovipositor length 420 (365-470, n=14), 1.95 (1.8-2.1) times as long as hind tibia.

Hypera nigrirostris (Fabricius) (slide in USNM) and some specimens from Ste. Clotilde, QU, ex. Conotrachelus geminatus (LeConte) (slides in CNCI)]. This segment is consequently slightly shorter and narrower than Fl,. However, the series of specimens from Monticello, collected by Dozier, neatly bridges the gap between A. pallipes and A. conotracheli because one female has both Fl, with 2 longitudinal sensilla, and the other two females have one Fl, without longitudinal sensilla and one with 1 longitudinal sensillum. Probably only one species is involved, with larger individuals parasitizing the larger eggs of Conotrachelus and smaller individuals parasitizing the smaller eggs of Cylindricopturus. The differences in the specimens reared from these two host genera parallels the differences found for A. iole and one of its synonyms reared from large and small mirid hosts. In the latter case, experimental support showed only one species was involved so the synonymy could be made with certainty (Huber and Rajakulendran 1988). Until such support is available for A. conotracheli and A. pallipes | retain the two species as distinct, mainly because a relatively large body of literature is associated with A. conotracheli. If crossing experiments show that the species are the same (as I suspect) then the name A. pallipes would have priority. Comments. Normally, the most common species from an area are collected first and usually described soon after. Passive collecting methods, such as pan or Malaise trapping that yield large amounts of material, were unknown or not used in Ashmead’s and Girault’s time. Rather, collecting consisted of sweeping and, in Girault’s case, searching panes of glass in greenhouses etc., or else host eggs were searched for and parasitoids reared from them. Thus, species, particularly economically important ones, that tend to search for hosts on aerial parts of plants (e.g. Cylindrocopturus adspersus on sunflower, Conotrachelus nenuphar on plum) would most likely be collected first, before species that search for host eggs near or at ground level. It is therefore not coincidental that the first two Anaphes species described from North America were A. pallipes and A. conotracheli, precisely those species of Anaphes most likely to be collected by sweeping, searching glass panes, or rearing eggs laid in easily accessible locations. Distribution. Canada (QC), USA (DC, GA, IL, MD, VA, WV). In addition, Johnson & Girault (1906) reported A. conotracheli from CT, KY, NC, and TX. Material Examined. 462 2 and 35c & (42 on slides).

Hypera nigrirostris (lesser clover leaf weevil). Specimens reared from C. geminatus collected in the field at Ste. Clotilde, QC, were successfully maintained for eight generations on Listronotus oregonensis 15 Journal of the Entomological Society of Ontario Volume 135, 2004 eggs in a laboratory colony at St-Jean-sur-Richelieu. No A. conotracheli were ever found on the latter host in the field. Quaintance (1906) reported 60-70% egg parasitism of C. nenuphar on inctichiciel in Georgia, and Johnson and Girault (1906) reported 16-70% parasitism. Brooks (1918) reported 39.5% egg parasitism of C. inaequalis on grapes. Marcovitch (1916) reported the sawfly Aprosthena zabriskei Webster & Malley (Argidae) on Portulaca oleracea L. as a host. The two specimens were identified by Girault but vouchers were not seen. If correctly identified, this would be the first published record of an Anaphes species reared from a species of Hymenoptera. Tedders and Payne (1986) recorded a species of Anaphes, possibly conotracheli, from C. schoofi Papp but voucher specimens were not seen. Garman and Townsend (1952) listed Conotrachelus nenuphar (Curculionidae) and Rhagoletis pomonella (Walsh) (apple maggot) (Tephritidae) as hosts. The host record of C. anaglypticus (Say) on Thalictrum pubescens Pursh. by Huber et al. (1997) is incorrect. Comments. The references to A. conotracheli by Porter and Alden (1921), Porter (1922), Schauff (1984a: 48), probably Porter (1928), Charlet and Balsbaugh (1984), and Solomon (1985) refer to A. pallipes as defined under that species below. I examined voucher specimens and compared them to the type of A. pallipes. Bakkendorf (1934) reared a species in Europe from dytiscid and chrysomelid eggs which he referred to as A. conotracheli but the specimens he reared from Agabus (Dytiscidae), and almost certainly also those reared from Chrysomelidae, are very likely misidentified and probably represent two species, neither of them A. conotracheli. Jackson (1956) noted that specimens she reared from Agabus sp. were not the same as A. conotracheli. Anaphes cotei Huber (Figs. 5, 20, 39) Anaphes cotei Huber et al.,1997: 970 (original description). Type Material. HOLOTYPE 2 (CNCI), examined (see Huber 1997), from CANADA: Nova Scotia, Great Village. . Distribution. Canada (NS). Diagnosis. Statistics of the antennal segments are given in Table XV to complement the description in Huber et al. (1997) and for comparison with the antennal descriptions of the other species redescribed here. Type measurements are given in Table I. The species is most similar to A. pullicrurus. Anaphes cotei has a relatively narrow forewing (Fig. 20) as in A. pullicrurus (Fig. 27) but the inner surface of the scape has bluntly pointed, oblique scales with slightly thickened apices, as in A. gerrisophaga (scales not clearly visible in A. pullicrurus). The antenna (Fig. 5) has 2 longitudinal sensilla on FI,, as in A. pullicrurus (Fig. 13) but each funicle segment is relatively longer and more slender than in A. pullicrurus.

Sitona hispidulus (Fabricius), the clover root curculio (Yeargan, 1985), S. humeralis Stephens, and S. lineatus (Aeschlimann, 1980). Aeschlimann (1986) reported 1.9-23.9% parasitism in Sitona populations sampled in various countries. The species was also able to complete development in S. cylindricollis Fahraeus and S. flavescens (Marsham) in the laboratory (W. Day, Newark, Delaware, personal communication). One generation takes about 11-13 days at 26.7°C (Leibee et al. 1979). Both thelytokous and bisexual populations may occur at the same locality (Aeschlimann 1990). Dysart and Bingham (1976) imported field collected A. diana from Département of Yvelines, France, into North America. It was first released against the local Sitona spp., primarily S. hispidulus, in an alfalfa field at the Beneficial Insects Laboratory, Newark, Delaware, during spring, 1976, and again in 1977. In total, 4009 adults were released. Laboratory reared, parasitized host eggs were also sent to cooperators in Moscow, ID, Urbana, IL, and Lexington, KY, for rearing and release. In 1978 and 1979, 7396 and 409 A. diana, originating from France and Austria, were released at Newark and, in 1979, another 1000 adults from France were released in Fayette Co., KY. By 1986, after several years of recovery attempts from field-collected S. hispidulus eggs, only three specimens had been found, suggesting that it had established, albeit at an extremely low parasitism rate. The two specimens from Nova Scotia (CNCI, point-mounted) appear to be A. diana but are slightly larger. They are tentatively treated as this species. The two Quebec specimens almost certainly are A. diana. It would be useful to rear specimens from eggs of Sitona in Quebec and Nova Scotia and cross them with European specimens (or North American lab. colonies obtained from Europe) reared from Sitona to determine if they are indeed the same 18 Journal of the Entomological Society of Ontario Volume 135, 2004 species. If they are the same then the species probably already occured in North America prior to deliberate introductions into the USA. This would not be surprising as the host plants were deliberately introduced long ago as forage crops and at least five species of Sitona (cylindricollis, hispidulus, lineatus, lineellus (Bonsdorft), and tibialis (Herbst)) were accidentally introduced and established in North America.

June 11, 1948 R.L. Doutt.” 2.“Anaphoidea gerrisophaga Doutt $ Paratype”. The paratype is in good condition, dorsal side up, with left wing and right antenna detached. Diagnosis. Forewing very narrow, FWL/FWW greater than about 8.3 (Fig. 22). Vertex, pronotum and mesonotum with long, strong setae (Fig. 41). Anaphes pullicrurus and A. cotei also have relatively narrow wings (FWL/FWW up to 8.59) but the setae on the vertex and mesonotum are short and inconspicouous (the head setae on the holotype of A. pullicrurus are missing so their size is unknown). The narrow wings of A. gerrisophaga also resemble those of A. sinipennis Girault (in the fuscipennis species group), but the clava in A. sinipennis is entire and bluntly rounded apically instead of being divided and more pointed. Description. Female. Colour (from uncleared type slides). Brown with antennae and legs slightly ligher. Forewing (Fig. 22) narrowly brown along posterior margin but slightly lighter than along anterior margin. Medial space appearing as a lighter longitudinal line between anterior, posterior and apical infuscate areas of disc. Body length. 503m (378-594, n=8, from critical point dried specimens). Head. Width 172 (145-198, n=7). Occipital suture straight (as in Fig. 30). Ocellar setae at least half as long as distance between posterior ocelli (distinctly longer than diameter of anterior ocellus). Antenna. Scape with ventral margin slightly, evenly convex, and inner surface with faint curved oblique striations, some with slight thickenings medially. Fl, and Fl, each with 2 longitudinal sensilla (Fig. 7); Fl, with 2 longitudinal sensilla in most specimens but one specimen with only 1 longitudinal sensillum on one antenna and 2 longitudinal sensilla on the other; Fl, either without or with 2 longitudinal sensilla. The holotype has 1 longitudinal sensillum on one antenna and none on the other. Measurements are given in Table XVII. Mesosoma. Pronotum and mesonotum with conspicuous, long and erect setae (Fig. 41). Wings. Forewing length 632m (472-838, n=13), width 67 (55-100), FWL/FWW 9.21 (8.37- 10.04), LMC 133 (93-172), their length about twice forewing width; marginal space 106 bo Journal of the Entomological Society of Ontario Volume 135, 2004 (67-167), medial space long and narrow, somewhat rectangular and extending medially about halfway along wing, cubital line of setae uniformly close to posterior margin. Hind wing length 613 (467-793, n=13), width 22 (16-29, n=14), with 6-8 microtrichia medially on blade in apical half, LMC 108 (87-135). Legs. Foretibia with about 4-7 sensilla chaetica. Hind tarsomere 1 1.05 (1.00-1.08, n=3) times as long as tarsomere 2. Metasoma. Ovipositor length 270 (212-344, n=11), 1.31 (1.05-1.43, n=11) times length of hind tibia, extending under mesosoma to base of mesocoxa (Fig. 41). Male. Total length of flagellum 803.

Fl, length/width ratio averaging 4.32, with 5 longitudinal sensilla. Variation. Anaphes gerrisophaga appears to be quite variable in size. Small specimens have no longitudinal sensilla on Fl, and the length/width ratio of Fl, can be small compared to that of large specimens. Although only two host species are known, other host eggs of varying sizes are likely parasitized as well, which would account for the size variation. Some of the numerous other insects, especially Coleoptera, and Diptera, and other Hemiptera associated with Lemna (Scotland 1939, 1940) are likely hosts and perhaps a variety of Odonata (Zygoptera) are as well. A complex of species may be involved, all collected near or on water and on different hosts. Because the kind of flagellomere variation that occurs among these specimens is similar to that found in A. pallipes (large specimens have longitudinal sensilla on Fl,, small ones do not, and somewhat intermediate conditions occur), I prefer to treat them all as one species until crossing experiments with specimens reared from different hosts show otherwise. Distribution. Canada (MB, ON, QC), USA (CA, MD, NY, VT). Probably widespread in the Nearctic region wherever water and host eggs occur. Specimens examined were mostly collected near or on water using yellow pan traps placed at the water’s edge or on rocks emerging from the water. Specimens with narrow wings that might be referrable to A. gerrisophaga were seen from Hawaii (2° 2, UCRC) and the Northwest Territories (12, UCRC). More material (for slide mounting) is needed from these areas to determine their identities more reliably. Material examined. 249 2 and 1c (15 on slides). CANADA. Manitoba: 2 mi. E.

(Gerridae), and a series from Lestes (Lestidae) eggs in Eleocharis obtusa. Comments. The forewings of the holotype are not positioned flat, hence appear to be slightly narrower than they actually are, which explains the unusually high length/width ratio for the holotype (Table I). The paratype, collected on a window pane, is not conspecific with the holotype and is therefore excluded from the redescription given above. Some specimens (USNM) identified as A. pullicrurus by A. Gahan and H. Dozier fit A. gerrisophaga better. These include the series reared at Ithaca from Lemna by M. Scotland and a male from Muncie, IL, collected by Dozier. The Dozier male is much larger than the single male reared by Scotland and the thoracic setae are relatively shorter (the ocellar setae are not clearly visible). Otherwise it seems to fit A. gerrisophaga better than A. pullicrurus because FWL/FWW is 8.83, closer to the ratio for the male reared from an unknown host in Lemna, which is 9.38.

Occipital suture straight (as in Fig. 30), ovipositor extending well under gaster (Fig. 42), forewing (Fig. 23) with posterior margin narrowly brown at least distally, Fl, (Fig. 8) with 1 or 2 longitudinal sensilla, gregarious in eggs of Listronotus oregonensis. Morphologically, A. listronoti is apparently indistinguishable from A. sordidatus. Biologically, the species can be distinguished because A. sordidatus is a solitary parasitoid in Tyloderma foveolatum and will not cross with A. sordidatus in the laboratory. Statistics of the antennal segments are given in Table XVIII to complement the description in Huber et al. (1997) and for comparison with the antennal descriptions of the other species redescribed here. Since the original description, two new morphological features have been found to separate A. listronoti from A. victus. Anaphes listronoti females have 6-9 sensilla chaetica type 4 on the clava compared with 10-12 on the clava of A. victus (van Baaren et al. 1999). Unfortunately, these are not clearly visible on dried or slide-mounted specimens so the feature 21 Journal of the Entomological Society of Ontario Volume 135, 2004 cannot be used for routine determination. The first instar mymariform larvae of A. /istronoti show no visible segmentation in contrast to those of A. victus, which are clearly segmented (van Baaren et al.1997). Distribution. Canada (ON, QC), ?USA (MI). Anaphes longiclava (Doutt) (Figs. 9, 24, 43) Anaphoidea longiclava Doutt, 1949: 158 (original description).

Anaphes longiclavus; Huber, 1992: 74 (list, incorrect species spelling). Type material. HOLOTYPE ? (EMEC), examined. On slide labelled: 1. “by sweeping native vegetation Morgan Hill, Calif. July 2, 1947 R.L. Doutt”. 2. “Anaphoidea longiclava Doutt ? Type” (red label). The type is in rather poor condition with body mounted laterally, head detached and mounted vertically, left eye torn away from vertex which, together with occiput, is slightly torn, left antenna and right antenna beyond pedicel broken off and positioned elsewhere on slide, and both forewings, right hind wing and left foreleg detached and positioned elsewhere on slide. Its measurements are given in Table I. PARATYPE ? (EMEC) labelled 1. “by sweeping Salix Rio Nido, Calif. May 28, 1947 R.L. Doutt”. 2.“Anaphoidea longiclava Doutt ? Paratype” (yellow label). The head with one antenna and body were remounted under two 6-mm coverships on the original slide after clearing in KOH. Diagnosis. Occipital suture straight (as in Fig. 30), ovipositor longer than metatibia and extending under mesosoma to base of mesocoxae (Fig. 43), Fl, without longitudinal sensilla (Fig. 9), hind leg with tarsomere | slightly shorter than tarsomere 2, FWL/FWW at most 5.4 (4.6 in holotype); body length 413. The small body size and relatively broader forewing distinguish A. longiclava from A. luna and A. diana. Anaphes longiclava is the smallest described native Nearctic species of the genus, only slightly larger than the introduced A. diana and equal to exceptionally small specimens of A. /una. Description. Female. Co/our. (From uncleared type slides). Brown with antennae and legs, especially tarsi lighter. The holotype is generally lighter in colour than the paratype. Forewing (Fig. 24) with a narrow brown margin in half of posterior margin. Body length. 413m (holotype). Head. Width 188 (n=1). Occipital suture straight (as in Fig. 30). Ocellar setae as long as about half diameter of anterior ocellus. Antenna. Scape with ventral margin moderately rounded, with extremely faint oblique striations on inner surface. BL Fl. and Fl. each with 2 longitudinal sensilla, Fl, with | longitudinal sensillum (Fig. 9). Fl, with ae stipircly narrower than apex. Measurement are given in Table XIX. Mesosoma. ey and mesonotum with moderately long setae. Wings. Forewing length 533 (n=1), width 115, FWL/FWW 4.63, LMC 149, their length about 1.3 times forewing width; marginal space 97, medial space triangular, cubital line of setae closest to posterior margin near the retinacular seta and further away distally, with a gap of about one setal length between the cubital line and posterior margin of wing. Hind wing length 500 (n=1), width 23, with 3 microtrichia medially on blade in apical half, LMC 178. 22 Journal of the Entomological Society of Ontario Volume 135, 2004 Legs. Foretibia with 8 sensilla chaetica. Hind tarsomere 1 slightly shorter than tarsomere 2 (Table I). Metasoma. Ovipositor length (n=1) 1.14 times length of hind tibia, extending slightly under mesosoma to level of base of mesocoxa (Fig. 43). Male. Unknown. Distribution. USA (CA). Material Examined. Only the two type specimens were examined. Hosts and Biology. Unknown. The holotype was collected by sweeping native vegetation and the single paratype by sweeping Salix. Comments. The wing proportions of the holotype and paratype of A. /ongiclava are quite different (FWL/FWW 4.63 and 5.32, respectively) and I am not sure if they belong to the same species. In the absence of a series of specimens variation cannot be adequately assessed. Specimens of an Anaphes sp. (in CNCI) similar in body length to A. longiclava were reared from Tanysphyrus lemnae (Fabricius) (Curculionidae) in Florida. They have a body length of about 310um, a small Fl, without longitudinal sensilla, and the ovipositor up to 1.7 times as long as the hind tibia. They may be A. /ongiclava but until specimens are reared from T. lemnae from California and more specimens are reared from this host in Florida and elsewhere to determine variation and geographic distribution more completely I hesitate to name the Florida specimens as A. longiclava. Otherwise, a host would now be known for A. /ongiclava.

(USNM), here designated. On slide labelled: 1.“Anaphoidea luna Gir. Types and Paratypes Type No. 15452 U.S.N.M. [red label]”. 2.“6655 Mymarid Parasite of Phytonomus (from shipment from Italy by Fiske) Salt Lake City Apr. 8 1911. T. H. Parks”. The lectotype is uncleared and mounted in lateral view at the edge of the coverslip and ringed by a faint blue line. The head is collapsed but otherwise in good condition. Measurements are given in Table I. A /ectotype is designated to fix the name by eliminating the possibility of confusion with similar species and because the original introduction of A. luna probably included more than one species. PARALECTOTYPES. Two females and three males on same slide as lectotype, all uncleared, intact, and mounted in lateral view near the edge of the coverslip. Diagnosis. Fl, without longitudinal sensilla. FWL/FWW less than 6.5. Ovipositor length 285 (252-335, n=G), extending under mesosoma only to about apex of mesocoxa. Body length about 413-603. The only described Nearctic species that has this combination of features is A. longiclava, a much smaller species that could only be confused with very small specimens of A. luna. This species is diagnosed (and redescribed) only from the specimens introduced in 1911 to avoid the problem of antennal variation (discussed below). Even so, it is difficult to diagnose A. luna because it has no remarkable features and seems to be quite variable. Specimens introduced from Europe in 1926 and those reared from Hypera postica in North America after that date may or may not be the same and are discussed below. Description. Female. Co/our (from uncleared slides). Dark brown with antennae and legs beyond coxae lighter. Forewing (Fig. 25) narrowly brown along posterior margin but lighter than along anterior margin. Girault (1914b) described the species as “black, the scape, pedicel and proximal three tarsal joints dusky lemon yellow, the trochanters and knees [i.e., junction of femora and tibiae] pallid . . . cephalic tibiae lighter”. Body length. 501 (413-603, n=10, from slide-mounted specimens). Body length is based on the original series from Portici and Salt Lake City (collected in 1911). Head. Width 203 (n=1). Occipital suture straight (as in Fig. 30). Ocellar setae a little shorter than diameter of anterior ocellus. Antenna. Scape with inner surface with very faint oblique striations. For specimens from original 1911 introduction, Fl,, Fl, and Fl, each with 2 longitudinal sensilla (Fig. 10); Fl, with 0-2 longitudinal sensilla. For specimens collected in North America since 1926 introductions, FL, Fl, Fl, and Fl, each with 2 longitudinal sensilla (Fig. 10); Fl, usually with 2 longitudinal sensilla on each antenna, rarely with 2 and 1, 1 and 1, 1 and 0, or even 0 and 0 longitudinal sensilla. Measurements are given in Table XX (specimens from original introduction into North America) and Table XXI (specimens reared from field-collected Hypera postica in North America). 24 Journal of the Entomological Society of Ontario Volume 135, 2004 Mesosoma. Pronotum and mesonotum with short, inconspicuous setae. Wings. Forewing length 652 (536-780, n=7), width 102 (85-137), FWL/FWW 6.40 (5.70- 7.13), LMC 141 (123-161), their length about 1.4 times forewing width; marginal space 100 (72-124), medial space triangular, cubital line of setae uniformly close to posterior margin with a gap of about half a setal length between the cubital line and posterior margin of wing. Hind wing length 623 (531-750, n=7), width 28 (24-34), with 0-12 microtrichia medially on blade in apical half, LMC 115 (105-130). Legs. Foretibia with 9-11 sensilla chaetica. Hind tarsomere 1 0.92 (0.86-0.98, n=2) times as long as tarsomere 2 (Table I). Metasoma. Ovipositor length 285 (252-335, n=6), 1.38 (1.25-1.50) times as long as hind tibia, and extending under mesosoma at least to apex of mesocoxa or as far forward as middle of forecoxa (Fig. 44). Male. Total length of flagellum (n=3) 206 (175-232). Length of antennal segments (n=2 to 5): scape 101 (100-103), pedicel 43 (41-44), Fl, 5 (4-6), Fl, 61 (56-65), Fl, 65 (56-76), Fl, 64 (47-69), Fl, 65 (49-72), Fl, 64 (55-72), FL 63 (53-68), Fl, 64 (51-71), Fl, 64 (50-71), Fl, 61 (50-68), FI,, 63 (55-67). Fl, length/width ratio averaging 3.12 (2.69-3.58), with 4 (?5) longitudinal sensilla. Variation. Anaphes luna is either a single very variable species or a complex of species. If it is a complex, many of the papers citing the name /una may not actually apply to A. luna (as described above, based on the type specimens). For example, vouchers of A. /una from the Ph.D. study by Gould (1986) may represent a different species. The Gould specimens differ from the type series in that Fl, bears 1 or 2 longitudinal sensilla on each funicle, as in A. victus, A. sordidatus and A. listronoti. Alternately, A. luna may simply be a very variable species, especially in the number and position of longitudinal sensilla on FI, and FI,. Evidence for this is provided by specimens examined from material collected since 1958 in the northeastern US and Canada. Among these, some specimens also had 2 longitudinal sensilla on Fl, but every combination was found at least once, i.e. 2/1, 2/0, 1/1, 1/0, 0/0. Similarly, most specimens had 2 longitudinal sensilla on Fl, of each antenna but the various combinations (except 2/0) were found in at least one individual. Such variation may occur at the same place and time. A slide with five females and a male reared on 19.v.1973 at Ithaca, NY, shows considerable variation in antennal sensilla, with FI, bearing 0/0, 1/0, or 1/2 longitudinal sensilla and Fl, bearing 0/1, 1/1, or 2/2 longitudinal sensilla. Specimens reared from alfalfa in Europe also show such variation, e.g., two slides of A. /una bearing six uncleared females from Arles, France, 6.i.1966 and ii.1966, alfalfa stems, F. Gruber (USNM). Two of the specimens have FI, bearing 2/1 longitudinal sensilla, two have 0/0 longitudinal sensilla and two have 1/0 longitudinal sensilla. All but one of the specimens collected in February have 2/2 longitudinal sensilla of Fl, and the one collected on 6.i has 2/1 longitudinal sensilla. The specimens were not reared from known host eggs so the possibility exists that the six specimens emerged from different hosts in the alfalfa stems, which may account for the differences in antennal morphology. However, it is more likely that all the specimens emerged from alfalfa weevil eggs. Crossing experiments need to be made between A. /una reared from alfalfa weevil and A. victus and A. /istronoti reared from carrot weevil and A. sordidatus reared from Tyloderma foveolatum to see if they are conspecific or if they are biologically distinct. Possibly, one of the species (probably A. victus, which has a similar ovipositor length and is solitary) described by Huber et al. (1997) is a synonym of A. luna. It would also be interesting to cross A. /una reared from 25 Journal of the Entomological Society of Ontario Volume 135, 2004 H. postica with specimens reared from H. eximia on Rumex to confirm that they are the same species. I am not completely certain that they are. Distribution. Europe, Canada (AB, ON, PE), USA (DE, IL, IN, MD, MI, MO, NJ, NY, UT, WV, WI). In 1928, when A. fuscipennis (as A. pratensis) was shipped from Utah to Indiana the shipment may have included some A. /una. Since then, A. luna has apparently become widely distributed in the northeast and north central USA (Radcliffe and Flanders 1998). Dysart and Day (1976) provided a detailed map of county localities. Bryan et al. (1993) stated that A. luna had not been redistributed but that it was well established in the USA and Canada. Material examined. 133 2 2 and 50 && (142 on slides) in USNM unless otherwise indicated.

Curculionidae are the only confirmed hosts and include in North America the alfalfa weevil, Hypera postica (Gyllenhal) on alfalfa and H. eximia (LeConte) on pale dock (Rumex ?orbiculatus Gray), and in Europe and North Africa the Egyptian alfalfa weevil, H. brunneipennis (Boheman), H. trilineata Marsham, possibly H. punctata (Fabricius), H. variabilis Herbst (Kaufmann 1941a), H. zoilus Scopoli (Baccetti 1957), and Hypera [as Donus] crinitus (Boheman). Baccetti (1958) was uncertain if the species he reared from H. crinitus was A. luna. One of the slides, bearing the number 6655 with specimens reared in Salt Lake City has host eggs labelled as Phytonomus [= Hypera] murinus F., which does not occur in N. America. The specimens from near Havana, IL, supposedly reared from Bathyplectes curculionis (Thomson) (Ichneumonidae) clearly are incorrectly associated with this host. They must have been reared from eggs of Hypera postica. Three slides of Anaphes, labelled s.l. # 3007, reared from Hypera punctata by Chamberlin, do not appear to be A. /una, which places doubt on Kaufmann’s (1941a, b) host record from Europe. Dysart and Day (1976) and Clausen (1978) summarized the biology of A. /una. Clausen (1940) 26 Journal of the Entomological Society of Ontario Volume 135, 2004 noted that in fresh alfalfa only eggs near the oviposition puncture can be reached for parasitism, but the female wasp can enter dry stems so the entire egg mass is then susceptible to parasitism. At least two generations per year occur. Females lay one or two eggs inside a host egg and egg parasitism seldom exceeds 5% both in Europe (e.g., El M’Sadda 1967) and North America (Radcliffe and Flanders 1998), though Brunson and Coles (1968) reported 10% parasitism. Nasr (1998) provided an abstract of the life cycle of A. una from H. brunneipennis in Egypt. A series of slides each labelled “ex. egg Hypera postica” (Jefferson Township, Green Co., WI) and each with either one female or one male specimen of A. /una seems to confirm Clausen’s (1978) statement that the species is solitary. But six slides each labelled “ex. alfalfa weevil ege” (Preston Co., WV), have five specimens per slide, and one has six specimens. Each of these slides has one or two males and the remainder are females. The species (if it is indeed the same species — I cannot tell, based on morphology) may therefore sometimes be gregarious (or else two species are involved). Introductions into North America. The original releases of at least 1740 adults of A. una from Italy were made near Salt Lake City from 1911-13 but the releases failed to become established (Chamberlin 1924a). New importations and releases were made from 1925-1928 (Brunson and Coles 1968) and included both A. /una and A. fuscipennis (as A. pratensis). According to Hamlin et a/. (1949), the two species were released together because they could not be distinguished when alive. The first recovery was in 1926, but of A. fuscipennis not A. luna, which apparently failed to become established. In addition to the type slide, five slides of specimens in the USNM with the same catalog number (Webster No. 6655) as the type slide were examined. Four are dated 1911 (3 April to 12 June, depending on slide) and one has no date. The specimens on these slides are evidently from the original introduction of A. luna into North America but do not form part of the type series. They are important because they contain three species, presumably all from material obtained originally from Portici, Italy. The undated slide bears one female of A. fuscipennis as well as a male and female of A. /una. The slide dated 3 April bears two females and two males of A. /una, and one female of a small specimen with ovipositor extending almost to the head and FI,-Fl, without longitudinal sensilla. It is very poorly oriented and its identity is unknown but it is very likely not a specimen of A. una. Another set of releases was made from 1925-1928, again from material from Italy. Five slides of voucher specimens (USNM) from the 1925-1928 introductions, labelled S.L. Sta. [St. Louis Station] #3007 and dated either 14 or 24 May, 1926, were examined. Three of these slides bear specimens reared from Hypera punctata. These appear not to be A. /una but key instead to a species close to A. leptoceras Debauche in Debauche (1948). The remaining two slides, labelled as “ex.stems alfalfa” contain A. /una. In 1933-34, A. luna from France was released in California. According to Dysart and Day (1976), A. /una was apparently mixed with A. fuscipennis (as A. pratensis) in all these introductions, so its early spread cannot be accurately assessed. If the specimens on these two sets of slides are representative of what was released in North America in 1911-1913 and 1925-1928 then at least two more species besides A. fuscipennis and A. luna may have become established on alfalfa weevil in North America. If so, that may account for the considerable variation seen in A. luna (see Variation, above). Fischer et al, (1961), van den Bosch (1964), Clancy (1969), and Clausen (1978) refer to a Patasson sp. reared from Hypera brunneipennis (Boheman) in Iran and Egypt that was released in California but apparently, and from a taxonomic viewpoint, luckily, did not become established. 27 Journal of the Entomological Society of Ontario Volume 135, 2004 Perhaps the species they referred to is the same as A. /una but I have not seen voucher specimens to verify this. In retrospect, it is impossible to know exactly how many species ultimately became established in North America from shipments originating from the Old World. Biological control. Many of the numerous references on A. /una mention this species in connection with biological control of the alfalfa weevil. Although A. /una had a relatively small role in the successful control of alfalfa weevil in northeastern North America, it nevertheless contributed, and still contributes, to.the overall reduction in damage by this pest. Continued search for races of A. /una, or very similar species of Anaphes that are more adapted to the drier conditions of the southern USA where alfalfa weevil or Egyptian alfalfa weevil are still important pests, may result in further introductions of Anaphes species. Anaphes luna has been recorded from Egypt (Nasr 1998) and Sicily (Pagliano and Navone 1995), both Mediterranean areas, so a suitable race or species for successful introduction into southern USA must exist. If further introductions of Anaphes spp. are made, it is essential, from a taxonomic viewpoint, that sufficient voucher specimens (at least 10 males and 10 females, killed directly in at least 70% ethanol) be preserved in major institutions for species confirmation. The doubt surrounding the identity of A. /una because of the release of a mixture of two or more species during the first half of the 1900’s, poor identifications, and too few, poor quality, voucher specimens should not be repeated. Comments. Girault (1929) incorrectly synonymized A. /una under A. conotracheli. Doutt (1949) accepted Girault’s (1929) synonymy and therefore did not include A. /una as a separate species in his key to North American species. Poinar and Gyrisco (1963), El M’Sadda (1967) and Collins and Grafius (1983) also mistakenly treated the two names as synonyms, presumably following Girault. Peck (1951) classified A. /una under A. conotracheli but then (Peck 1963) noted that it should perhaps be regarded as a distinct species. Burks (1967) correctly removed it from synonymy after examining the types. At least one other species of Anaphes (belonging to the fuscipennis species group) was reared from alfalfa weevil (Indiana, Harrison Co. 20.ii.1967, R.C. Anderson, 1% and 1 on slide, USNM). This species appears to be undescribed and is likely to be found’ normally on a host other than alfalfa weevil or it may be rare.

Originally mounted in balsam under one coverslip on slide labelled: 1. “A/aptus 13807 [pencil] pallipes Ashm. Jacksonville, Fla Type”. 2.” 28 Journal of the Entomological Society of Ontario Volume 135, 2004 (Alaptus) Anaphes pallipes Ashm. ? Type No. 13807 U.S.N.M. [red label]”. The holotype was in poor condition, uncleared and mounted laterally with face head up (Fig.45). One forewing was detached and obliquely positioned at some distance from body. The remaining wings, clava of left antenna, Fl, and clava of right antenna, tarsus of right foreleg and left middle leg, trochanter of right middle leg, and right hind leg were missing. I successfully removed the specimen from the original slide, cleared it in KOH and remounted it under two coverslips so that critical diagnostic features could be observed. Measurements are given in Table I. Ashmead (1887) miscounted the antennal segments on the holotype, evidently not realizing that the clava from each antenna was missing. He mistook the last flagellar segment for a clava and therefore counted only five flagellomeres. This explains why he placed the species in Alaptus. Because of his mistake his description of the antenna is inaccurate and misleading. Diagnosis. Occipital suture short and oblique, pointing ventromedially towards occipital foramen (Fig. 31). Inner surface of scape and pedicel with distinct, oblique cross striations. Flagellum with longitudinal sensilla on BL, Fl, and Fb but none on Fl » Which is consequently shorter and narrower (Fig. 45). Two specimens from Zilker Park have only 1 (0?) longitutinal sensillum on FI, and FI, of at least one flagellum (Fig. 12). The only described Nearctic species that could be confused with A. pallipes is A. conotracheli. Specimens of A. pallipes are smaller than A. conotracheli in all measurements, probably due to the smaller host from which they have been reared. As mentioned under A. conotracheli, the species are probably the same. Because of the considerable literature on A. conotracheli | do not synonymize it under A. pallipes until crossing experiments or molecular data can confirm their conspecificity. Description. Female. Colour (from critical point dried specimens). Body brown; legs almost white except for coxae, femora medially, and tarsomere 4 which are light brown. Forewing (Fig. 26) with posterior margin clear to apex of wing or at least distinctly lighter brown than anterior margin, except for a short brown section subapically.

Antenna. Inner surface of scape with distinct cross striations almost at right angles to length of scape. Fl,, Fl, and usually Fl, each with 2 longitudinal sensilla (Fig. 12, 45). Measurements given in Table XXII. Mesosoma. Pronotum and mesonotum with short, inconspicuous setae. Wings.

The specimens from Cylindricopturus adspersus mentioned by Schauff (1984a) as being A. conotracheli are treated here as A. pallipes. The specimens from Connecticut, determined as A. conotracheli by Gahan, were reared from Rhagoletis pomonella Walsh (Tephritidae) by Porter and Alden (1921). Porter (1922) and Porter (1928) reported up to 25% and 30% parasitism of R. pomonella at Wallingford, CT. Comments. The homotype and plesiotype no. 44,225 (from Centralia, IL) that Girault (191le: 279) designated and referred to as A. pallipes actually belongs to Anaphes iole of the fuscipennis species group (Huber and Rajakulendran 1988, Huber 1992). As pointed out by Underhill (1926: 17) the occurrence of A. pallipes reared from cages containing Gnorimoschema operculella Zeller is doubtful. No mymarids are reliably known to parasitize lepidopterous eggs so this reference to A. pallipes is almost certainly incorrect. Anaphes pallipes probably has a wide North American distribution, based on the little material seen so far. The host genera Cylindrocopturus and Rhagoletis are widespread and further rearings from any species in these genera may yield A. pallipes.

The specimen is uncleared, in fairly good condition, mounted laterally, with both hind wings, and Fl, + club of right antenna detatched and positioned away from the body, and tarsomeres 2-4 of the left hind leg missing. Holotype measurements are given in Table I. PARATYPE. The female collected on 30 August 30 Journal of the Entomological Society of Ontario Volume 135, 2004 was examined and appears to be conspecific with the holotype. It is on a slide that also bears a male of A. Ziole, a female of Anagrus sp., and a female of Camptoptera pulla. Girault described A. pullicrurus from four females “on the panes of a small window” at Centralia, IL, on 26 and 30 August and 5 September, 1909. Two slides bearing only part of the series from which Girault described the species were located. The paratype female collected on September 5 is lost (D. Webb, Illinois Natural History Survey, pers. comm.). The fourth paratype female is also apparently lost, unless it is the male of A. 7iole. It is unlikely, however, that Girault would have confused this female for a male. Diagnosis. Forewing narrow (FWL/FWW 7.0-8.6), thoracic setae short, inconspicuous; funicular segments relatively short and broad. Anaphes pullicrurus, A. gerrisophaga and A. cotei all have relatively narrow forewings. Anaphes pullicrurus differs from A. gerrisophaga by its short, inconspicuous thoracic setae and a relatively wider forewing (long, distinct setae and narrower forewing in A. gerrisophaga) and from A. cote by Fl, and the remaining funicular segments relatively shorter and broader (compare Tables XXIII and XV). Description. Female. Co/our (from uncleared, slide-mounted specimens). Body brown; legs lighter, uniformly brown except for base of femora at junction with trochanters. Forewing (Fig. 27) with posterior margin narrowly brown along its entire length. Girault (1910) described the colour in detail and his description is certainly more accurate, as it is based on at least one specimen that was not first slide mounted. Body length. 460 (450-480, n=4). Head. Width 167 (paratype) and 197 (specimen ex. Chaetocnema denticulata). Occipital suture straight (as in Fig. 30). Antenna. Inner surface of scape not clearly visible on specimens examined. Fl, & Fl, each with 2 longitudinal sensilla (Fig. 13). Measurements given in Table XXIII Mesosoma. Pronotum and mesonotum with short, inconspicuous setae. Wings. Forewing length 612 (585-634, n=5), width 77 (72-86), FWL/FWW 8.03 (6.99-8.59), LMC 124 (115-135), their length about 1.6 times forewing length; marginal space 79 (74-86), medial space triangular, cubital line of setae closest to posterior margin near the retinacular seta and slightly further away distally, with a gap of about one setal length between the cubital line and posterior margin of wing. Hind wing length 570 (519-593, n=5), width 23 (20-25), with 0-4 microtrichia medially on blade in apical half, LMC 176 (173-203). Legs. Foretibia with 8-10 sensilla chaetica. Hind tarsomere 1 0.91 (0.83-0.95, n=5) times as long as tarsomere 2. Metasoma. Ovipositor length 296 (272-312, n=5), extending under mesosoma past base of mesocoxa (Fig. 46) Male. Unknown. See comments below. A male identified as A. pullicrura collected by sweeping a creek bed in Muncie, IL has the same wing proportions as A. pullicrura but is much larger.

Chaetocnema denticulata (22 2, USNM). Hosts and Biology. Chaetocnema denticulata (Illiger) (Chrysomelidae). Poos (1955) noted the 31 Journal of the Entomological Society of Ontario Volume 135, 2004 maximum developmental time of 11 days in C. denticulata eggs exposed to A. pullicrurus in the laboratory. He reared females only. Apparently, only one individual developed within each host egg, but this was not definitely established. Comments. Three specimens besides the type series were mentioned by Girault (1910). One female collected June 9 in a greenhouse is on a slide together with six Anagrus armatus (Ashmead). The latter species undoubtedly is a misidentification other species of Anagrus, as explained by Chiappini et al. (1996: 573). It has short, inconspicuous thoracic setae and a FWL/FWWof 6.97 (left wing) and 6.40 (right wing). I treat it as probably A. pullicrurus. A male collected July 1, 1910, is on a slide together with seven Camptoptera pulla Girault. It appears to belong to A. gerrisophaga on the basis of its long, prominent head and thoracic setae but its forewing is too broad to be A. gerrisophaga; it has a FWL/FWW of only 6.59 (wings obliquely positioned so width of one wing and length of other wing measured to obtain ratio). The second male that Girault (1910) also collected on July 1 was not found. On the basis of known hosts, A. gerrisophaga should be restricted to near or on water whereas A. pullicrurus should be in fields (which of course may be near water so A. gerrisophaga could easily disperse into them). The collection locality of the type series of A. pullicrurus does not help in determining a natural habitat. Dispersing or wind blown specimens could easily end up in a greenhouse regardless of the host they parasitize or the habitat they normally occupy. More material reared from Chaetocnema spp. is needed to search for better characters to define A. pullicrurus and assess its variation more thoroughly.

Anaphes sordidatus; Huber et al., 1997: 961 (type material, redescription, literature). Type material. LECTOTYPE ? (INHS), examined (see. Huber et a/. 1997) from USA: Illinois, Centralia. Diagnosis. Occipital suture straight (as in Fig. 30), ovipositor extending under gaster (Fig. 47), forewing (Fig. 28) with posterior margin narrowly brown at least distally, Fl, (Fig. 14) with 2 longitudinal sensilla, solitary in eggs of Tyloderma foveolatum. Statistics of the antennal segments are given in Table XXIV to complement the description in Huber et a/. (1997) and for comparison with the antennal descriptions of the other species redescribed here. Type measurements are given in Table I. This species cannot be distinguished morphologically from A. /istronoti. One character that may possibly separate the species is the sculpture of the mesoscutal midlobe posteriorly. The sculpture consists of reticulate sculpture apparently arranged in somewhat longitudinal elliptical pattern compared to a more circular pattern in A. /istronoti. Biologically, A. listronoti differs by being gregarious and having a different host, Listronotus oregonensis. The two species do not interbreed in the laboratory (Huber et al., 1997). Anaphes sordidatus is similar to A. victus (Huber et al. 1997) and to specimens of A. /una that have Fl, with two longitudinal sensilla. Even though there is a difference in ovipositor length between A. sordidatus and A. luna and they appear to be morphologically distinct, it would be interesting to conduct crossing experiments between them to see if A. sordidatus is also biologically distinct.

Type material. HOLOTYPE $ (CNCI), examined (see Huber et a/. 1997) from CANADA: Quebec, Ste. Clotilde. Diagnosis. Occipital suture straight (as in Fig. 30), ovipositor extending under gaster (Fig. 48), forewing (Fig. 29) with posterior margin narrowly brown at least distally, Fl, (Fig. 15) with 1 or 2 longitudinal sensilla, solitary in eggs of Listronotus oregonensis. The ovipositor is shorter than in A. sordidatus, and A. listronoti which is morphologically the most similar species to A. victus. Possibly, A. victus is the same as A. una, as discussed under the latter. Statistics of the antennal segments (Tables XXV and XXVI) are given to complement the description in Huber et a/. (1997) and for comparison with the antennal descriptions of the other species redescribed here. Type measurements are given in Table I. See diagnosis of A. listronoti for additional features to separate it from A. victus. Distribution. Canada (QC), USA (MI, TX). Comments. This solitary species (only one adult emerges from one host egg) is very similar to specimens reared from Hypera postica since the mid-1950’s and identified as A. /una. Crossing experiments betwen A. victus from L. oregonensis on carrot and A. /una from H. postica on alfalfa should be undertaken to see if they are the same species. 33 Journal of the Entomological Society of Ontario 3 Volume 135, 2004 Table I.

ROMANKOVA Entomology, Department of Natural History, Royal Ontario Museum, 100 Queen’s Park, Toronto, Ontario, Canada M5S 2C6 E-mail: tatianar@rom.on.ca Abstract J. ent. Soc. Ont. 135: 87-99 Seventeen species of Epeolini (Nomadinae) are reported from Ontario, including ten species of Epeolus Latreille and seven of Triepeolus Robertson. A key to the species is presented, along with descriptions, notes about their phenology and locality records. Species recorded from Ontario first time are **Epeolus autumnalis Robertson, EF. bifasciatus Cresson, **E. ilicis Mitchell, E. interruptus Robertson, **E. lanhami Mitchell, E. minimus (Robertson), Triepeolus cressonii (Robertson), **T. junctus Mitchell, ** 7. lunatus (Say), ** T. michiganensis Mitchell, T. pectoralis (Robertson), **7. remigatus (Fabricius) species marked with (**) are also first recorded for Canada. Introduction Little is known about Epeolini in Ontario, and until now only five species belonging to this tribe have been reported from the province, four of which are in the genus Epeo/us (MacKay and Knerer 1979; Mitchell 1962). Examination by the author of bee specimens in several Ontario insect collections showed that at least 17 species of Epeolini occur in Ontario, including seven species of Triepeolus, and ten species of Epeolus. The earlier recorded presence of E. banksi Cockerell, was not confirmed by our studies (MacKay and Knerer 1979). The purpose of this report is to allow accurate recognition of the species of Epeolini in Ontario, and to update information regarding their presence in the province. Materials and methods A total of 425 specimens of Epeolini were examined from the Entomology collections at the Royal Ontario Museum (ROME), University of Guelph (DEBU), and Canadian National Collection of Insects (CNCI) as well as types and comparative material from the California Academy of Sciences (CASC), Illinois Natural History Survey (INHS), and Academy of Natural Science, Philadelphia (ANSP). Morphological characteristics, flight period, and species distribution data for Ontario are based on specimens from these collections. Morphological terms used in this paper are defined and illustrated in Michener (1944, 2000) and Rightmyer (2004). Abbreviations used are as follows: F — flagellar segment, T — metasomal tergum, S — metasomal sternum. Species new for Ontario are designated by an asterisk; those with two asterisks are first recorded for Canada. Species identification was done or confirmed using Mitchell (1962). Morphological characteristics for the generic diagnosis follow Rightmyer (2004). Overall geographical distributions of the species in North America are based on Hurd (1979) and Mitchell (1962). 87 Journal of the Entomological Society of Ontario Volume 135, 2004 The distributional data are presented in the form of an annotated list and are illustrated with maps. The locality records in the annotated lists are arranged from north to south according to Ontario’s primary administrative divisions (the administrative categories, i.e., “county’, “district”, etc, are omitted). Tribe Epeolini Ontario bees of the tribe Epeolini are distinguished from other bees of the provincial fauna as follows: metasoma conical; all tagmata with white hair pattern; head, mesosoma, apex of metasoma, and partly legs often orange; axillae produced posteriorly to a point or rounded; marginal cell rounded apically and away from wing margin; female S6 retracted, emarginate medially, and with posteriorly directed lateral processes. With respect to the two genera found in Ontario, males and females of the same species have similar body hair patterns, microsculpture, and pubescence; males tend to have denser pubescence on the face and mesepisternum. All of the species are cleptoparasitic on other bees. Genus Epeolus Latreille Body length 6-10 mm. Maxillary palpus usually two-segmented, rarely three-segmented. Mandibles may have a subapical tooth. Antennal pedicel of the male is usually mostly exposed. S7 of the male usually lacking median emargination on distal margin, with lateral lobes above interlobal area, and with apical setae mostly dorsal, on surface leading from lateral lobe. Base of gonostylus with dorsal protuberance. T5 of the female with transverse, silvery pseudopygidial area. S6 of the female with processes paddle-shaped, distal margin denticulate. Parasites on Colletes bees (Colletidae). Key to Epeolus species of Ontario The species descriptions, following dash in couplets, involve only the most important characteristics for the recognition of the species treated in Ontario. 1.

MARSHALL, S.M. PAIERO, AND O. LONSDALE Department of Environmental Biology, University of Guelph Guelph, Ontario, Canada, N1G 2W1 E-mail: samarsha@uoguelph.ca Abstract J. ent. Soc. Ont. 135: 101-107 The following ten Orthoptera species are recorded from Canada for the first time, in some cases also representing new records at the generic level: Melanoplus scudderi scudderi (Uhler), M. walshii Scudder, Dichromorpha viridis (Scudder), Ellipes gurneyi Giinther, Neoxabea bipunctata (DeGeer), Oecanthus latipennis Riley, O. laricis TJ. Walker, O. exclamationis Davis, Meconema thalassinum (DeGeer), and Neoconocephatlus triops (Linnaeus). Oecanthus argentinus Saussure, previously known from western Canada, is recorded from Ontario for the first time. Some additional records are given for rare species previously known only from one or two Canadian records, and the significance of these new records is discussed. Although these new records were generated by observation and collecting efforts throughout southern Ontario, most are from a few small and significant Carolinian sites. Introduction Vickery and Kevan’s (1986) monographic treatment of the orthopteroid insects of Canada is the only species-level treatment of an entire major order for the country, providing an essential identification guide and a benchmark against which later distributional records can be assessed. We summarize the significant new Canadian orthopteroid records that have accumulated in the University of Guelph Insect Collection during the almost two decades since the publication of Vickery and Kevan (1986). We also provide further records for species previously unknown in Ontario but recorded elsewhere in Canada, and for species previously known only from one or two locations in Canada. Most of our new records are from ongoing arthropod surveys at several important Carolinian sites throughout southwestern Ontario. All the specimens examined are deposited at the University of Guelph Insect Collection, but some records are from the Royal Ontario Museum as indicated (ROM). Part one: Orthoptera not previously recorded from Canada: Acrididae Melanoplus scudderi scudderi (Uhler) is known from throughout the eastern U.S., but had not been previously recorded from Canada. We found this to be a common species late in the season on low shrubbery in Ojibway Prairie Nature Reserve (Essex County). It also occurs in oak-savannah habitat in Lambton County. 101 Journal of the Entomological Society of Ontario Volume 135, 2004 Label data: Ontario: Essex Co.: Windsor, Ojibway Prairie, 42°15'51”N 83°4’30”"W, sweeps, 22 September 2001, S.A.

Ellipes gurneyi Giinther is a western species known from a few eastern localities in Pennsylvania and Michigan (Bland 2003). We here record it from Port Rowan and Long Point. Label Data: Ontario: Hald.-Norfolk Reg.: Port Rowan, 2 Jun 1940, EA. Urquhart (ROM); Long Point, 5 Sep 1987, J. Troubridge. Gryllidae Neoxabea bipunctata (DeGeer), the Two-spotted Tree Cricket, is a distinctively coloured species that occurs throughout most of the eastern USA south to Mexico. We here record it from the Ojibway Prairie Nature Reserve, where we have observed this species annually since 1999, and from specimens collected in the 1970s in the Harrow area. The latter specimens were apparently overlooked by Vickery and Kevan (1986). 102 Journal of the Entomological Society of Ontario Volume 135, 2004 Label data: Ontario: Essex Co.: Windsor, Ojibway Prairie, 42°15’51”N 83°4730”W, 12 September 1999, S.A.

Oecanthus latipennis Riley occurs from Illinois and Connecticut south to Florida and Arizona, so it is not surprising to find it in Ontario. It has probably been overlooked because of its predominantly arboreal habits. Label data: Ontario: Essex Co.: Pelee I., Stone Rd. Alvar, 41°47’N 82°40’W, 1 October 2000, S.A. Marshall; Kent Co.: Clear Creek, 10 August 2000, S.A. Marshall (photographs only). Oecanthus laricis T.J. Walker is a rarely collected species previously known only from Ohio and Michigan. We here record it from larch (Larix laricina) trees in a small Carolinian fen in Ontario.

Ocecanthus exclamationis Davis occurs from Illinois and Connecticut south to Arizona and Florida, and was previously known from Michigan near the Ontario border. It was not surprising to find this species in Ontario. Label data: Ontario: Essex Co.: Point Pelee Natl. Pk., Tilden’s Woods Trail, 21 September 2000, O. Lonsdale; Pelee I., 30 September 2000, M. Cripps. Tettigoniidae Meconema thalassinum (DeGeer) is an introduced species initially recorded in North America from New York (Gurney 1960) and now known from Rhode Island (Hoebeke 1981) and Michigan (Bland 2003). This species, and the subfamily Meconematinae, are newly recorded from Canada. We record it here from Harrow. Label Data: Ontario: Essex Co.: Harrow, hand collected, 11 Aug 1997, M. Beaudoin. Neoconocephalus triops (Linnaeus) occurs in the southern United States and the Caribbean, and undoubtedly represent adventitious specimens. Vickery and Kevan (1986) record this species as adventitious but do not indicate where in Canada, if at all, it was recorded. Label data: Ontario: Wellington Co.: Galt, 20 February 1956, D.H. Pengelly. Toronto, University Ave., 29 March 1933, S.L. Thompson (ROM); Ottawa, 15 February 1923, in bananas, L.E. Johnson (ROM) Part two: Orthoptera not previously recorded from Ontario: Gryllidae Oecanthus argentinus Saussure occurs across the continent from British Columbia to Connecticut, but it has not been recorded from eastern Canada. Vickery and Kevan (1986) suggest that this species “will be able to move northward only to a limited extent” and state that the “prevalence of frosty periods in late September in Ontario would not allow late-maturing individuals to reproduce”. They do, however, note that some northwestern populations cope 103 Journal of the Entomological Society of Ontario Volume 135, 2004 with the relatively short seasons by producing only a single annual generation. Ontario populations are probably also univoltine. Label data: Ontario: Middlesex Co.: Komoka Feed Mill Prairie, yellow pans, 42°58’N 81°25’W, 13-30 August 2001, S.M. Paiero. Part three: Orthoptera previously known only from one or two Canadian records: Acrididae Melanoplus differentialis differentialis (Thomas) (the Differential Grasshopper), unlike the other species discussed here, is a pest species that has probably been moving its range northward for several years (Cantrall 1968). Vickery and Kevan (1986) record it from “extreme southwestern Ontario” where it has long been established at Point Pelee. We find this large, distinctively marked species to be very common at a number of sites in Essex and Kent Counties, and record it as far north as Wellington County.

Tettigoniidae Microcentrum rhombifolium (Saussure) was previously known from only one site in Canada (Point Pelee), although it has also been recorded as an adventive species in British Columbia. We here record it from Harrow and Windsor. Label data: Ontario: Essex Co.: Windsor, 42°18’N 83°1'W, hand collection, 21 September 1997, B. Sabara; NE of Harrow, 42°2’N 82°55’W, 5 September 1992, W B.

We here report it only from nearby sites in Haldimand-Norfolk County. Ontario's other Atlanticus species, A. testaceus (Scudder) remains known only from one record at Arner, Ontario (Walker 1905). 104 Journal of the Entomological Society of Ontario Volume 135, 2004 Label data: Ontario: Hald.-Norfolk Co.: Manestar Tract, 1 October 1994, D.

Gryllidae Anaxipha exigua (Say) (Say’s Bush Cricket) is an uncommon species described by Vickery and Kevan (1986) as occurring in wet areas and near water. The only previous Canadian record of this species was Point Pelee, but we find it to be abundant on the foliage of small shrubs at a number of tallgrass prairie and oak savannah sites.

Oecanthus pini Beutenmiiller is a rarely collected species in Ontario, previously recorded only from Essex and Kent Counties. We here record it from Haldimand-Norfolk and Halton Regions. 105 Journal of the Entomological Society of Ontario Volume 135, 2004 Label data: Ontario: Hald.-Norfolk Reg.: Manester Tract, 6km NNW St. Williams, 42°42°17”N 80°27'38"W, 24 August 2001, S.A. Marshall; Halton Reg.: Speyside, on Pine trunk, 4 October 2003, S.A. Marshall. Discussion Most of the new records included here have resulted from new arthropod survey and inventory projects along Ontario’s southern fringe, almost entirely in the same protected sites that have recently yielded numerous new records in other taxa (Sugar et al. 1998; Bouchard et a/. 2001; McCorquodale 2001; Skevington et a/. 2001; Buck 2004; Paiero et al. 2004). Some of the newly recorded species are relatively common in southern Ontario and have simply been overlooked, while others are widespread just south of Canadian border and were expected to occur in extreme southern Ontario. Neoxabea bipunctata, Dichromorpha viridis, and Microcentrum rhombifolium, for example, are colourful, easily identified species that occur in a variety of habitats in the United States but appear to be restricted to one or two sites in Canada. More importantly, a significant proportion of the newly recorded species are relatively rare in Ontario and have been overlooked in the past due to their limited ranges and narrow habitat requirements. Melanoplus scudderi and M. walshii, for example, are brachypterous grasshoppers that occur in highly localized populations in two or three tallgrass prairie or oak savannah reserves. These species, like Neoxabea bipunctata, Dichromorpha viridis and Anaxipha exigua, are provincially or nationally rare species with easily recognizable and easily monitored populations. Other newly recorded species, such as Ocecanthus laricis, might be genuinely rare, or might only appear rare because they are difficult to collect. Both Oecanthus laricis and the similar O. pini have been recognized as species of special conservation concern in other jurisdictions (Dunn 2002). The species treated above represent a large proportion of Ontario’s rare Orthoptera, and include many distinctive and relatively easily identified grasshoppers and crickets of potential conservation concern. We hope that the data presented here will encourage further consideration of putatively rare Orthoptera both as indicators of threatened habitat and as threatened species in their own right.

The IRM had a more extensively modified program with no applications of OP, carbamate, or pyrethroid insecticides (Table I). Where alternatives were unavailable or were unacceptable to the grower, border sprays of OP or pyrethroid insecticides (applied tol-2 outside rows) were used as deemed necessary by the grower. Border sprays were not used in the grower-devised plots. Rates used were those recommended in the provincial fruit production guide (Anonymous 2002). Insecticides for control of overwintered (spring) OBLR were applied about petal fall (early June). For control of the first summer generation of OBLR, (late June-July), sprays were timed according to established degree day models (Solymar 1999) using five pheromone (OBLR lure, Trece, Salinas CA) baited traps (Pherocon II, Trece) at each site to obtain the date of the first sustained moth captures. Traps were separated by at least 30m and examined twice weekly as described in the protocol outlined by Solymar (1999). First applications of insecticides were delayed until 240-260 degree days Celsius (DDC) (base 6.1°C). Applications were repeated if emergence of moths was extended. Insecticides were applied for other pests as identified as necessary by the growers but trap catch data from codling moth, Cydia pomonella (L.) (Lepidoptera: Tortricidae) and apple maggot Rhagoletis pomonella (Walsh) (Diptera: Tephritidae) traps as well as weekly scouting for the occurrence of mullein plant bugs, Campylomma verbasci (Meyer) (Hemiptera: Miridae), aphids, Aphis pomi (DeGeer) and Dysaphis plantaginea (Passerini) (Homoptera:Aphididae) etc. were provided to support spray timing and/or needs for control treatments (Table I). Sampling procedures, traps, appropriate timings, etc., were as outlined by Solymar (1999). Monitoring of resistance OBLR larvae (200-400) of the overwintered (spring) generation were collected from each plot at each site in spring of each year of the study (2000-2002) just after bloom and prior to any insecticide treatments, and placed on an artificial diet (Pree et al. 2001). Moths developing from these collections were reared and larvae produced from mass crosses were assayed for resistance using a Potter spray tower and analytical grade samples of insecticides dissolved in acetone (Pree et al. 2001). Concentrations used as diagnostic were 40 mg/kg for azinphosmethyl and 2.5 mg/kg for cypermethrin (a pyrethroid). At these diagnostic concentrations, all susceptible individuals were killed; the 40 mg/kg concentration of azinphosmethyl! killed ca. 15% of a laboratory selected OP-resistant population used as a reference or standard resistant population in earlier studies (Pree et al. 2001) and the 2.5 mg/kg solution of cypermethrin killed ca. 50% of a similarly selected pyrethroid-resistant population. For tests, we used 10 replications of 10 larvae at each diagnostic concentration. Tests were conducted on at least two days and larvae were from at least 6 egg masses. Because the inequality of variances prevented transformation of these data to fit a normal distribution, the percentage of resistant individuals in each plot in each year was compared using the Mann-Whitney rank sum test (Zar 1974) (P<0.05, SigmaStat, Version 2, SPSS Inc., Chicago IL). Comparisons were made separately between treatments (grower-devised vs. IRM) and for changes in population responses between years for each treatment. Efficacy The effectiveness of the programs in controlling OBLR was determined approximately one week prior to harvest by assessment of fruit for larval feeding damage. Sample trees (5% of the 113 Journal of the Entomological Society of Ontario Volume 135, 2004 trees in each plot) were selected randomly, and 50 fruit were examined on each tree. Ladders were used on larger trees and adjacent trees were sampled where less than 50 fruit were available. Percentage fruit damage from each plot at each site was compared with the Mann-Whitney rank sum test (SigmaStat). Overall means for fruit damage at the three sites in the grower- devised and IRM plots were compared using the same test. Results and Discussion Insect control programs at the three sites varied widely, with the grower’s experience dictating the need for the various insecticides applied for pests other than leafrollers (Table I). The sites at Brighton and Grafton had more insecticides applied than the Grimsby plots. Growers were advised of the presence of OP resistance in OBLR populations in both plots at their sites and all avoided the use of OPs for control of OBLR. Therefore, any differences or reductions in resistance observed between the two programs were likely associated with resistance selection caused by OP (or pyrethroid) use for other pests. The number of treatments of OP insecticides applied for control of other insects or carbaryl (a carbamate insecticide) for thinning (removal of excess small fruit ) in mid-late June varied from one-two at Grimsby to four-five at Brighton, and to four-nine at Grafton (Table I). In 2000 at Grimsby in the grower-devised plot, for OBLR the grower made a single application of cypermethrin (Table I). In the IRM plot, he made three applications of Bt, as Foray 48BA, for control of the spring generation and two more for the first summer generation. The OBLR populations in the grower-devised plot were reduced to levels that prevented further samples in that plot in the subsequent years of the test. There was no significant difference for the OP resistance and the pyrethroid susceptibility between the populations of the two plots in 2000 (Tables II and II). However, the OP resistance significantly decreased from 2000 to 2002 in the IRM plots, and the pyrethroid susceptibility did not change over that same period. In 2000-2002 at Brighton in the grower-devised plot, for OBLR the grower made a combination of Bt, spinosad and deltamethrin applications (Table I). In the IRM plot, he made applications of Bt and spinosad. There was no significant difference in the OP resistance between the populations in 2000 and 2002, however, in 2001 the OP resistance in the grower- devised plot was significantly greater than in the IRM plot (Table II). OP resistance significantly decreased after two years of treatments in the grower-devised plot from 2000 to 2002, whereas, in the IRM plot OP resistance significantly decreased after one year (Table II). Pyrethroid susceptibility was significantly greater in the grower-devised plots than in the IRM plots in 2000 and 2001, however, in 2002 there were no significant difference between the plots (Table III). Pyrethroid susceptibility significantly increased after two years in the grower-devised plot from 200 to 2002, whereras in the IRM plots there was no change in susceptibility (Table III). In 2000 at Grafton, the OBLR population (or at least a substantial portion of the population) was exposed to a prebloom pyrethroid treatment applied to control spotted tentiform leafminer (Phyllonorycter blancardella F.). Therefore, except at Grafton, estimates of the percentage resistance in populations (Tables II and III) were established early in 2000 prior to any insecticide use. Changes in resistance are measurements of the impact of control programs used in 2000-2002. In 2000-2002 at Grafton in the grower-devised plot, the grower made a combination of Bt, spinosad and deltamethrin applications (Table I) for OBLR. In the IRM plot, he made applications of Bt and spinosad. There was no significant difference in the OP resistance between the populations 114 Journal of the Entomological Society of Ontario Volume 135, 2004 in 2002, however, in 2000 the OP resistance in the IRM plot was significantly greater than in the grower-devised plot and the reverse was true in 2001 (Table II). OP resistance in 2000 was significantly lower than in 2001 and 2002 in the grower-devised plot, whereas in the IRM plot the reverse was true (Table II). Pyrethroid susceptibility was significantly greater in the grower-devised plots than in the IRM plots in 2001 and 2002, however, in 2000 there were no significant difference between the plots (Table III). Pyrethroid susceptibility was variable in the same way in both plots from 2000 to 2002; the OBLR populations were significantly more resistant to pyrethroids in 2001 relative to 2000 and 2002 (Table III). Application of a pyrethroid (cypermethrin) to a similar population at the Grimsby site reduced populations to levels, which prevented further samples for resistance testing. In this case, numbers of OBLR surviving in this plot were high enough to allow collection of a sample adequate (>200 larvae) for tests of resistance frequencies. At both Grimsby and Brighton, in populations sampled in spring 2000, prior to the establishment of the two programs, the grower-devised and IRM had similar resistance levels (Table II). At both sites, the populations in both plots were largely resistant to OP insecticides (71-87% survival) but were susceptible to pyrethroids (0-19% survival). At Brighton, OP and pyrethroid resistance was not detected after one year (as measured in 2001) in the IRM plot and after two years in the grower-devised program plot (as measured in 2002). Both of these plots were adjacent to large wood lots on at least two sides and migration of susceptible moths from these areas may have influenced the rate of changes in the susceptibility of these populations. OBLR has an extremely wide host range and larvae could develop on many rosaceous or nonrosaceous species (Chapman and Lienk 1971). Both treatment groups at Brighton and the IRM group from Grimsby remained susceptible to pyrethroids (Table III). At Grafton, OP resistance was initially higher in the IRM plot than in the grower-devised plot (84% vs. 45%). Under the grower’s program, OP resistance increased from 45% to 91%, probably associated with the extensive OP program used for other insects. While OP resistance declined somewhat in the IRM plot in the first year of the test (from 84% to 64%), the decline was not continued in the second season. This plot received approximately nine border sprays of OP insecticides in the second season and these may have affected any further decline of this resistance. The percentage of the population exhibiting pyrethroid resistance was unchanged over the two seasons in both plots, even though after one year OBLR populations were more resistant (Table III). The decrease in damage to apples in Grimsby and Brighton by the OBLR from 2000 to 2002 (Table IV) was parallel to the trend of decreasing resistance of OBLR to both OP and pyrethroids (Tables II and III). However, damage declined in plots with either treatment over the three years of the study. This was probably associated with the large initial variation in infestations between sites in 2000. However, at Grafton in spite of the trend of decreasing damage to apples over the same period (Table IV), there was no similar parallel decrease in OP and pyrethroid resistance (Tables II and III). Overall, OP resistance declined, or, at least, did not increase in plots with a IRM strategy that avoided the use of OP and pyrethroid insecticides both for OBLR and for other pests. OP resistance also declined at Brighton under the grower-devised program that avoided the use of OP or carbamate insecticides for OBLR control. Resistance was lost more rapidly in the IRM plot at Brighton. It is likely that the extensive use of border sprays of OP insecticides (up to six were applied to the IRM plot) at Grafton delayed or reduced the decline in the numbers of 115 Journal of the Entomological Society of Ontario Volume 135, 2004 TABLE II.

In laboratory studies, Pree et a/. (2001) found that resistance declined from 88% to about 12% in the laboratory over three generations when selection was not applied to a newly colonized population. Smirle et a/. (1998) reported similar declines in resistance in laboratory populations from Quebec. In these field studies, we found similar rapid losses in resistance when selection pressures were removed or minimized. Similar rates of loss were observed with a pyrethroid -selected laboratory colony (Pree, unpublished data). The data generally indicate that resistance in the OBLR can be managed and that programs which use azinphosmethy] in a rotation with Bt preparations and/or spinosad, compounds that do not exhibit cross resistance to OP or pyrethroids (Pree unpublished, Ahmad et a/. 2002), may be sustainable. The data also indicate that pesticides applied against pests other than OBLR are important in the selection of OBLR populations for resistance and must be considered as part of any resistance management strategy. However, as the data indicate, resistance management strategies that consider these aspects can be successful and can result in rapid loss of resistance. A rotational program that incorporates azinphosmethyl is about 50$C/ha/yr cheaper than a program that relies on a rotation of Bt and spinosad. However, a number of the products used as replacements for OP and pyrethroid insecticides (e.g., tebufenozide, imidacloprid etc.) are costly and may make the modified program more expensive overall. The exact cost is likely to be highly variable and dependant upon the pests identified as problems in the various orchards. However, the value of continued efficacy and potential sustainability of the program to the producer must also be considered. This program may lose some feasibility if the use of ‘17 Journal of the Entomological Society of Ontario Volume 135, 2004 azinphosmethyl is severely reduced or curtailed, but the broad range of compounds involved in the resistance suggests that similar programs with other compounds may be feasible. Carriére et al. (1996) have shown a positive correlation between resistance to azinphosmethyl and resistance to cypermethrin in populations from Quebec but our field studies identified two populations (Grimsby and Brighton) that were resistant only to OP insecticides and not to pyrethroids. However, the population from Grafton was resistant to both groups of insecticides. These observations and those of Ahmad et a/. (2002) and Pree et al. (2002) suggest that resistance in the OBLR, to these different insecticides, is a variable system and that the importance of the various resistance mechanisms may vary with the different types of insecticides used in control programs. Despite the broad-spectrum resistance to many insecticides associated with OP or pyrethroid resistance in the OBLR, a potentially sustainable resistance management strategy involving the rotational use of three groups (Bt, spinosyn, and OP) of insecticides is feasible.

Ont. 135: 119-123 The multicoloured Asian lady beetle, Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae), has become a pest of grapes, Vitis vinifera L. (Rhamnales: Vitaceae), in Ontario because beetles present in harvested grapes produce alkaloids (methoxypyrazines) when stressed or as a pheromone, and these can affect the quality of wines and juices. We have assessed the use of selected insecticides in both laboratory and field to determine the potential for control of this pest. Although, the neonicotinoid acetamiprid was most toxic in the laboratory, malathion or cypermethrin were most effective in the field. Malathion was less persistent than cypermethrin; effects were lost within 7 days whereas cypermethrin residues reduced beetle numbers in plots for at least 7 days. Introduction The multicoloured Asian lady beetle , Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae), is common in southern Ontario, and like many other species of lady beetle is normally classed as a valuable beneficial species. Introduced initially into North America from Asia in 1916 and in repeated releases since, it has provided effective biological controls in a number of agricultural ecosystems (pecans, strawberries and roses), and is the most common predator of the Chinese soybean aphid, Aphis glycines Matsumura (Homoptera: Aphididae) (cited in Koch 2003). However, H. axyridis has become a pest of fruit crops and grapes in Ontario, because in autumn, beetles aggregate and feed on these crops. Whether the beetles cause the primary damage or feed at sites damaged by other insects or birds is not clear but a recent report (Koch et al. 2004) indicates a preference for damaged fruits. However, they have become a serious problem on grapes, Vitis vinifera L. (Rhamnales: Vitaceae), because beetles are present in harvested bunches and are crushed with the grapes. H. axyridis, and some other species of lady beetle produce methoxypyrazines as both an attractant (pheromone) and as a defense mechanism to protect beetles from predators (Hodek 1973). The quality of wines produced from these infested grapes is seriously affected (Pickering et al. 2004 ) and up to 20% of the wines produced in Ontario in 2001 were tainted (G.M.W, personal communication). This has created a requirement in some seasons for control of these beetles on grapes grown for both wine and juice in Ontario. As part of an initial response to this problem we have investigated the use of selected insecticides. Most of the literature on the effects of pesticides on H. axyridis relates to the impact of insecticides on these insects as a non-target species but there are a number of studies summarized by Koch (2003). Generally, these studies indicated that 219 Journal of the Entomological Society of Ontario Volume 135, 2004 adults were less sensitive than larval stages. Further, as a group, pyrethroids were most toxic but there were large differences between the various pyrethroids. Carbaryl was rated as highly toxic to adults but few data on the effects of organophosphorus insecticides were presented in Koch’s (2003) review. The neonicotinoid acetamiprid was rated highly toxic to eggs, larvae and adults in laboratory studies by Youn et a/. (2003). Another neonicotinoid, imidacloprid, was less toxic to late instar larvae and pupae. We have assessed a number of insecticides in laboratory and field but because H. axyridis becomes a pest of grape within a few days of harvest, we restricted compounds tested in the field to malathion, acetamiprid and cypermethrin which are registered for use close to harvest (three- seven days preharvest). Carbaryl is allowed up to five days of harvest in Ontario, but residues detected in wine from such uses preclude its use here. Methods Laboratory Bioassays For assays, we used beetles collected from unsprayed vineyards of cv.Riesling in the Vineland area in October 2003. Beetles were collected in polyethylene vials lined with plant leaves, and were held overnight in a refrigerator at 4°C. Insecticides, (malathion, purity 99%, cypermethrin, 98%, permethrin, 98%, and carbaryl 98%) were analytical grade samples (Chem Services, West Chester PA) and acetamiprid, 99.9% a.i., (Bayer Inc, Etobicoke, ON) were applied to beetles in five mL of analytical grade acetone using a Potter spray tower (12 s spray time followed by five s settling time). Controls were treated with five mL acetone. Beetles were anaesthetized with CO2, 30 s at 30 kPa and placed upright in glass Petri dishes on a Whatman #1 filter paper, five/dish, for treatment. Treated beetles were held in 200 mL glass jars for 24h in a rearing room at 22 + 2°C, 60%RH with a photoperiod of 16:8 (L:D). Beetles unable to walk after prodding with a fine brush were considered dead. For calculation of concentration/ response regressions, six concentrations with ten replicates of five beetles were used. Tests were over several days. Data were subjected to probit analysis (POLO-PC LeOra Software, Berkeley, California). Differences in responses of beetles to the various insecticides were considered different if the 95% confidence limits at the LC50 did not overlap. To determine whether beetles recovered from treatments of acetamiprid, cypermethrin or malathion, we treated ten replications of five beetles at one of the concentrations used in the calculation of the concentration/response regressions described above and assessed mortality at 24, 48 and 72h post treatment to determine whether mortality changed over time (i.e., whether beetles recovered from treatment or more were affected). Differences in means for the three post treatment times were tested with an analysis of variance. Field Tests Tests were conducted in a ca. ten -year-old vineyard of cv. Riesling near Vineland, Ontario, where earlier observations had indicated high numbers of beetles. Plots were located on a south facing edge of the vineyard and clearly held a population of H.axyridis. Treatments were replicated four times with plots (five vines/plot) arranged in a randomized complete block design. Insecticides, malathion (Malathion 500EC, United Agri Products, London, ON), cypermethrin, (Cymbush 250EC, Zeneca Agro,Stoney Creek ,ON) and acetamiprid (Assail 7OWP, DuPont Canada Inc., Mississauga, ON) were applied 23 October 2003. These insecticides were diluted to a rate comparable to 3000L/ha and sprayed to runoff using a Rittenhouse truck-mounted 120 Journal of the Entomological Society of Ontario Volume 135, 2004 sprayer (Rittenhouse Sprayers, St Catharines, ON) equipped with a Spraying Systems handgun fitted with a D-6 orifice plate. Pressure was set at 2000 kPa. Each plot required eight to nine L of spray mix. Plots were sampled one day (24 October) and seven days (30 October, 2003) after treatment when total numbers of beetles in bunches and on leaves were recorded for each plot. Data were transformed (log (x+1)), analyzed by ANOVA, and means separated with a Tukey test (P=0.05) . Results and Discussion Laboratory bioassays showed that acetamiprid and cypermethrin were most toxic to beetles (Table I). Another pyrethroid, permethrin was less toxic than cypermethrin but was ca. equitoxic to malathion or carbaryl. Observations reported were 24h post treatment. Beetles treated with acetamiprid were affected (appeared immobilized) at concentrations lower than we used in bioassays but these responded as capable of normal movement when prodded. Observations 24, 48 and 72 hours after treatment indicated increased mortality of beetles treated with acetamiprid (Table II). Earlier reports (Williams and Fickle 2003) with another neonicotinoid, imidacloprid, indicated initial knockdown followed by recovery, but this did not occur with acetamiprid. Mortality associated with treatments of cypermethrin or malathion was unchanged in these later observations. TABLE I.

A number of beetles on acetamiprid-treated vines were affected similarly to those in the laboratory but crawled readily when placed on the hands of the observers. In other treated plots most dead beetles were on the ground under vines but a few dead individuals were caught up in the grape bunches. In our survey of the literature, we did not find information on whether or not dead beetles are a potential source of methoxypyrazines, or how long these compounds might persist in dead insects. In samples seven days post treatment, plots treated with cypermethrin had fewer beetles than control plots but there were no differences between insecticide treatments (Table III). Whether the numbers surviving in this plot (mean of seven beetles over five vines) are above a threshold which could result in off flavors in wine produced 121 Journal of the Entomological Society of Ontario Volume 135, 2004 TABLE II.

In any case, itwould beadvantageous for dead beetles to fall to the ground so they would notbe harvested with the grapes. The lack of control with acetamiprid was surprising given the results of the laboratory assays: the rate we tested in the field was based on rates recommended (Anonymous 2003) on grape for leafhopper control. Reissig (2003) reported that another neonicotinoid, imidacloprid, which was highly toxic in laboratory tests against apple maggot, (Rhagoletis pomonella (Walsh)) (Diptera: Tephritidae), was less effective than expected when applied to foliage in the field. Hu et al. (1998 ) speculated that the ineffectiveness of imidacloprid against apple maggot in the 122 Journal of the Entomological Society of Ontario Volume 135, 2004 field might be associated with rapid absorption and consequent inactivity against insects on the surface or to rapid degradation by sunlight. Cypermethrin-treated plots had fewer beetles (than controls) in samples both one day and seven days post treatment indicating that toxic residues persisted at least seven days. Malathion reduced beetle numbers in samples one day post treatment, but was not effective in the sample seven days post treatment. Currently, cypermethrin has a seven-day preharvest limit on grape (Anonymous 2003) and appears to be the product of choice based on these trials. However, it is not registered for use in the U.S. and would not be useful on grapes grown for juice for export. Malathion was effective in samples one-day post treatment and can be used up to three days preharvest and might be used on grapes grown for export. This study has identified two insecticides that reduced infestations of H. axyridis on grapes, and which may be used close to harvest when beetles become a problem. This may provide an immediate or short-term response to a new problem but in the longer term, management of beetle populations below a still to be determined threshold by other means is desirable. H. axyridis is beneficial throughout much of its life cycle, and effective populations should be preserved.

Biodiversity Books, Forest Hills, New York. 96 pp. ISBN 0-9754015-0-5. $20 US. Once in a while a landmark resource guide is produced. Ed Lam has done just that with his excellent new guide to the adult damselflies of northeastern North America. While many guides have been produced recently for Odonata (dragonflies and damselflies), none have managed to take the advances that have occurred within the realm of bird field guides and adapt them to this group of insects — until now! Unfortunately, however, it only covers one half of the order — the Zygoptera or damselflies. This suborder is, however, the one that provides the most grief and frustration for those beginning to learn how to identify Odonata. The guide itself is relatively small and compact, measuring 5.5 by 8.5 inches, with a total of 96 pages and could, therefore, be easily carried in the field. It covers 69 species and subspecies of damselflies and is fully illustrated-with more than 300 detailed paintings, drawings and photographs. The text is well written and the illustrations are nothing short of spectacular! They are so detailed that they have a photographic quality to them. The guide begins with an introduction to damselflies, followed by a nicely written overview of their life cycle. Next, a richly illustrated, two-page spread covers all of the adult anatomical features, including wing venation, relevant to species identification. A wonderful section entitled “Species Identification” acts as a “how to” for species identification at three levels: in the field, in the hand, and under the microscope. Also included in this section are useful tips on how to catch and collect damselflies. Finally, within the introductory section, two pages provide information on how the species accounts are organized. The species accounts themselves are well organized and attractively laid out with a full page dedicated to a single species. The illustrations include a dorsal view for males (complete with accurate wing venation — no small task!) and lateral views for both sexes. When necessary, additional lateral views illustrate different colour forms or mature versus immature individuals. Illustrations (some black and white, others in colour) are also provided, when necessary, to illustrate features such as male or female genitalia, or more detailed patterns of the head, thorax or abdomen. Key markings and features are indicated by lines pointing directly to the feature with a short description (e.g., “segments 8-10 completely blue”). Each species account contains a general description of the damselfly (complete with measurement ranges in both inches and millimeters) along with notes on its habitat, distribution and status. At the bottom of each page, a section provides detail on similar species — an indispensable feature for a field guide. Icons for each species (and sex), indicate whether it can usually be identified by binoculars, requires a hand lens, or if it a microscope is needed — this is a unique and useful feature of this guide. A silhouette is also featured providing the actual size of an average specimen. Finally, a range map is provided for each species, indicating known distribution to the county level. Each of the three families, and most of the genera within the family Coenagrionidae (pond damsels), begin with a page introducing the family or genus and is accompanied by a photograph or two and an excellent overview of the group. 125 Journal of the Entomological Society of Ontario Volume 135, 2004 Within the genus Enallagma (American bluets), many females can only be reliably identified by examining details of their thorax (mesostigmal laminae) under a microscope or with a powerful hand lens, While many books and guides in the past have chosen to ignore this, Lam rises to the occasion and provides the user with an appendix illustrating these features. Although this is, in my opinion, the best guide ever produced on the subject, it does have some faults. As far as the production is concerned, some pages are already becoming loose on my copy. Although I find it hard to put the book down, I can’t say that it’s been extensively used and I fear what effect a few trips in the field will have on it. I’m also disappointed in the coverage depicted in the range maps. Strictly from an Ontario perspective, it’s unfortunate that the extreme southwestern tip of the province has been cut off and that more of northern Ontario is not included. From a broader Canadian perspective, the map could have been extended to the east and the north to encompass all of the Maritime Provinces and northern Quebec without having to add any species. A user from Nova Scotia or Newfoundland may not realize, for example, that the guide is actually fully applicable to their area. Along the same lines, the area of coverage could have been extended west to include Michigan, all of Ohio, Indiana, Illinois, Wisconsin and northwestern Ontario with the addition of only two species (Argia plana and Coenagrion angulatum, the latter of which is the only Ontario species not featured in this guide). I realize that a cut-off has to be made somewhere but I think that the area covered could have been greatly increased with minimal effort. Users from Ontario also need to be aware that Smoky Rubyspot (Hetaerina titia), illustrated on page 22 of the guide, does not have extensively dark wingtips in this part of their range. Rather, the dark tip on the wing is barely discernable. “Our” form is not illustrated nor is it mentioned in the text. In fact, the only mention of variation is that males may be MORE extensively marked in dark brown on the wing than is illustrated. This is unfortunate and will surely confuse many users from this part of their range — possibly leading them to misidentify Smoky Rubyspots as American Rubyspots Hetaerina americana (a closely related, but more common species that shares many characteristics), The above faults are minor in the big picture. As stated earlier, in my opinion this book is the best guide ever produced for Odonata. Ed Lam has raised the bar considerably within the realm of Odonata field guides. This guide deserves a place both on the bookshelf and in the field bag of anyone with an interest in damselflies. Amateur naturalists with an interest in learning the damselflies, who have been either intimidated in the past by the technical nature of scientific treatments or frustrated with the lack of sufficient detail in the available field guides, will find that this is the guide they have been waiting for. Experienced entomologists and odonatologists will also find this book to be a wonderful and informative resource. Now we just need a companion volume for the dragonflies!

Intercept Publishers, Ltd., Andover, UK. ISBN 1-898298-92-0.70£ or 112 Euros. I wanted to be an ornithologist by the age of four. Bird-watching controlled my life until 16 years later when a peripheral interest in insects was rekindled, leading to a 30-year career studying bees and butterflies. I enthusiastically agreed to review “Insect and Bird Interactions” (IBI) which the book's cover informs us “...is the first of its kind to explore the diversity of interactions between insects and birds.”Given my personal experiences, I had a set of topics I hoped would be explored (including butterflies and bees!). Having birded several spring migration hot-spots, like Point Pelee, I was particularly interested in how hungry birds affect the phenology and abundance of the insects they encounter during the 3-4 weeks of migration. Although I was somewhat disappointed because IBI failed to cover this and most other topics on my mind, as a consequence | learned about many other topics. Part 1 of the book discusses “population management issues.” The first chapter (as well as Chapter 16) demonstrates that in simple environments, we can obtain insights and model populations with a high degree of certainty. However, when that focus is shifted to more complex communities of birds and their prey (Chapter 6), we see that for most birds the real world is too messy to allow modeling in all but the most intensively studied systems. Chapters 2-4 discuss the depressing effects of modern agriculture on natural biodiversity. The difficulty of precisely determining the insects that comprise the foods of any bird species in a community, coupled with the contributing factors of variable farming techniques and applications of pesticides by growers, make it impossible to directly link changes in bird populations with specific agricultural activities. Nevertheless, numbers of many British birds are declining in part due to new farming practices, especially the loss of buffer zones around fields and the removal of weeds with herbicides. The best data are derived from detailed studies of the Grey Partridge (Chapters 3 & 7). I enjoyed the detailed account of the chough, for which a strong relationship between livestock grazing patterns and crane fly ecology seems to determine the quality of foraging conditions and consequently nesting success for the birds. This is an excellent example of research that provides humans with information we can use to modify farming activities to improve conditions for birds. Chapters 7-9 concern the effects of insecticides on bird populations. The overall tone is that insecticides are generally bad for birds—a fairly safe assumption that nevertheless demands empirical support. Unfortunately, the authors are forced to rely extensively on logic and “soft” data because the complexity of the systems limits our ability to conduct “hard” tests; consequently, their arguments will fail to convince the skeptics. From an historical analysis, Colin Walker (Chap. 9) suggests that the use of cyclodiene insecticides, not DDT/DDE, were probably responsible for the egg-shell thinning that led to declines of Sparrow hawks and Peregrines in the UK. Unfortunately, American data are only briefly referred to, leaving me uninformed about how the UK experience relates to the generally accepted story that DDT and its metabolite DDE caused declines in raptors in North America. Part 3 has 8 chapters concerning foraging behaviour of birds. I was impressed with the complex colour vision of birds that includes perception of UV-wavelengths (Chaps. 10 & 11). In addition, the story that I learned long ago, that birds have a poor sense of smell, is shaken by experiments in which birds adjust their feeding in response to various odours (Chap. 12-15). 127 Journal of the Entomological Society of Ontario Volume 135, 2004 These chapters force us to rethink warning colouration and mimicry in insects in terms of the visual and olfactory stimuli that specific avian predators can perceive, Also, we cannot assume that one bird perceives an insect in the same way another does, further complicating the study of mimicry, Detailed analysis of the ant prey of wrynecks (Chap, 16) clarifies why this species can survive in both natural and highly managed ecosystems, but fails to provide guidance for us to conserve this uncommon and declining species because “the impact of modern agricultural practices on ant communities is not known,” The last three chapters concern the ectofauna of birds, Chapter 18 reviews the various defenses birds have against ectoparasites, | was disappointed that the authors chose not to discuss the evidence relating to the well-known Hamilton and Zuk handicap principle. On the other hand, the extent co which bill morphology represents a compromise between preening and foraging abilities was particularly interesting, Chapter 19 provides a strong argument that young Common Cuckoos acquire their lice from conspecifics on the wintering grounds, However, it is poor science to use data from obligate brood parasites (cuckoos) to question the vertical transmission of lice from non-parasitic parents to their young, As is true of many edited volumes that emerge from symposia, the various styles and variable depths of the book's chapters fail to provide a comprehensive overview of the subject. Several chapters could have been replaced, Chapter | (shorebird ecology) and Chapter 10 (the avian retina) make no mention of insects, (The relevant information from Chap, 10 is repeated and placed in entomological context in Chap, 11), Chapter 20 was written for phylogenetic specialists and the primary message will escape most readers, Some other chapters are so specific (i.e, individual experiments) that the uninformed reader will have difficulty placing them into context, Many topics and taxa (¢.g., bee-eaters, honey-guides) were neglected, Despite these shortcomings, | learned many interesting things from IBI, as highlighted above, It is discouraging that for most bird species, complex diets coupled with species-specific olfactory and visual abilities, temporal changes in insect communities, and complex interactions with numerous other birds and insects, make it impossible to fully understand their effects on individual insect species, With the added unknowns of global warming and a paucity of ornithologists who understand insects (and vice versa), it becomes apparent that this topic will remain blurred for years to come, Although too complicated for most birders, this book will appeal to both insect and bird behaviourists and ecologists, The early chapters should also be of interest to people interested in the effects of modern agricultural practices on natural communities, However, | am unsure how many of these individuals will find enough of interest to be satisfied, Academic institutions should purchase IBI as a reference work, DR, GARD W, OTIS Department of Environmental Biology University of Guelph Guelph, Ontario Canada NIG 2W1 gotis@uoguelph.ca 2004 ANNUAL MEETING The Entomological Society of Ontario is grateful for the support received from Entomogen Inc. and Totallybuggy Ltd. for the 141st Annual Meeting held in St. Catharines ON at Brock University on November 5 to 7, 2004.
