OUT STANDING- BHUOMOLOGICriL FEATURES IN THE UNITED STATES FOR MaY, 192o
During the coming month careful observations should he made by all Survey Collaborators working in the regions where Brood XVII of the periodical cicada is due to appear this year. This is one of the problematical broods with but few well developed colonies ever reported. It has been reported from Virginia, Georgia, Iowa, and Missouri in past yenrs.
Brood "«." of white grub adults is due to occur in the east-central States, lather heavy flights have already been recorded from southern Illinois and parts cf Indian?.. Reports of unusual abundance, of the beetles have also been received from Iowa, Missouri, Kansas, and Mississippi,
Cutworms still continue to be important factors in the insect damage of this spring, a very unusual outbreak of the variegated cutworm having been reported from Mississippi and Texas.
Indications point to a rather serious Hessian fly infestation of wheat in Kansas
Chinch bugs seem to "be unusually abundant in central and south-central Illinois, and -in parts of Kansas. The outbreak in Mississippi reported last year does not seem to be abating. Reports of unusual abundance have already been received from Tate and Marshall Counties in the State.
Telegraphic communication dated June 4 informs us that the fall armyworn is appearing in enormous numbers and defoliating corn, cene, sorghum, alfalfa, etc. , in southern Louisiana.
Aphids attacking deciduous fruits still continue to bo unusually scarce in the New England and Middle Atlantic States, extending westward to Missouri. South of North Carolina aphid s seem to be normally abundant.
The tent caterpillar is being reported as unusually abundant from th Connecticut River Valley westward into New York State, and southward t Virginia.
The corn ear worm has practically destroyed the peach crop on a 4,000- tree plantation in Georgia owing to a failure to turn under a hairy vetch crop early in the season.
One of the most serious insect outbreaks en pecan that has come to 'the attention of the State Entomologist of Mississippi is the outbreak of the cambium curcplio, Ccnotrachelus anaglypticus Say, reported from the Pearl River section of that State.

OUTSTAIIDDTG EJEPOMOLOGIIEiL PICTURES IN CAITADA, FOB. MAY, 1926
Grasshoppers ;nere hatching in all sections of southern British Columbia at the end of April and,, by the middle of May, -ere noticed abundantly in many parts of the -orovince. Poisoned bait mixing stations are in operation from, the Peace river district to the International
boundary. .
The cricket, Anabrus longfrpes Caudell, is causing important damage at Vernon, British Columbia. • ■
The western army cutworm has appeared in outbreak form over a large section of southern alberta. Depredations by this spe :ies and the early cut-orra, Euxoa tristicula Korr« , have been reported from many parts of Saskatchewan. Cutrorms are proving very troublesome in the Vernon district,
British Columbia.
a serious outbreak o.f the red-backed cutrorm, Eluxoa t ochrogast er Gn.» is believed to be developing in. soma sections of southern Manitoba.
The -bronzed apple tree ^eevil, Kagd^lis.aennscens Le2., -hich breeds in dead and dying trees is cE.us.ing foliage injury in orchards, in some sections of1" the Okanagan valley, British Columbia.
The oblique-banded leaf-roller is an insect of major importance in the orchards of the Okanagan Volley, 3, C, thi* season. T.ie tarnished plant bug has caused marked injury to apple buds Ln sections of the valley..
The strawberry' root reevi'?.-, is more numerous in the Victoria district, British Columbia, than for many years, "nd -ill probably cause considerable
dam- -■. .
The Barfly, Allantus mell^ues Tor ton haf been found in greenhouses at
Iloncton, Her Brunswick, on roses rec ntly iimpo^ted from the United States.
• Pea reports of insect activity have beer received from Eastern Canada ^hcre the spring leather has been cold °nd V ck-ard.

... GENERAL FEEDERS
VffllTE GRUBS (Phyllophaga spp. )
Masssachusetts A. I. Bourne (May 21): The first May beetles were collected the night of May l6 and 17, although to date very few of the "beetles have "been found.
Indiana
Illinois
Iowa
Missouri
Kansas
Mississippi
H. F. Dietz (May IS): May beetles have been very abundant at lights at night since May 5«
J. J, Davis (May 25): Have been abundant the -oast month. An unusual abundance was reported from Argos on May 17- Reports continue to be received calling attention to the abundance of white grubs in northern Indiana last season.
W» P. Flint (May IS): The present season is one in which the major flight of adults of brood A "rould be expected. Rather heavy 'flights of May beetles have been noted in southern Illinois by S. C. Chandler, and in western Illinois by J. H* Bigger. In the eastern and northern parts of the State moderately heavy flights of May beetles occurred.
C. IT. Ainslie (May IS): The emergence of adults at Sioux City has been retarded by cool, dry weather but they are now appearing in large numbers at lights, Lachnosterna implicita Horn and Lachno sterna rugo sa Melsh, are common
L. Baseman (May 20): Since about May 10, two species of June Beetles (?) have been on wing in great .numbers collecting about shade trees and coming to lights,
A, C. Burrill (May 22): Field corn is not up but local gar- dens suffer from above pests in many olaces in Jefferson City. I suppose that late season and weak corn, only a few inches high, has intensified the gardeners' troubles.
J. W. McColloch (April 5): White grubs have caused serious damage to nursery stock grown at Bartlett. (May 7): Adults of this species were received from Salina with the information that they were defoliating elms.
R. W. Harned (May 13): Although May beetles are apparently not so abundant this year as during several previous years, complaints have been received in regard to their damage to pecan trees. From Scooba, Miss. , on May 10, a correspondent wrote that most of the leaves and twigs from his young pecan trees had been eaten by May beetles. He reported them so numerous that they sounded like smarms of honeybees on his trees at night. The specimens that he sent proved to be Phyllophaga hir ticula and Phyllophaga praetermissa. Phyllophaga mi cans is the species that has been collected most abundantly this spring, especially from the southern part of the State. Up to May S, 5,SH8 May

W. L. Gray, Inspector for the State Plant Board at Natchez, Hiss., reports that many pecan trees on properties in Adams and Wilkinson counties in the southwestern corner of Mississippi have "been practical ly defoliated by May beetles. Ho beetles "'ere collected, so we can not be certain what species has caused this damage.
-On May 19, Inspector J. P. Kislanko, Ocean Springs, Miss., wrote: "It might be of interest to you to know the damage that May beetles have caused in some sections of this territory. Yesterday ^e visited A, V7. King, 7 miles north of Ocean Springs, to inspect his nursery. I "»as very much astounded. Every pecan tree on his place was completely defoliated by May beetles, apparently by Phyllophaga mi cars, and Phyllophaga mi cans var. c.xnvl if or mis . The orchard appears as though it was dormant. The pecan nursery stock was also ruined. Ne^ leaves are being formed since the beetles havecoommenced to disappear. Mr. King states: 'There io on© no,,T to every 10 a -"eek ago.1 He also states that each night he had a fire built in his yard and the beetles would come in multiple millions. I should have mentioned that the pecan trees in Ocean Springs suffered no noticeable injury from May beetles, but k miles north of Ocean Springs the work of the beetles is serious and becomes more so farther north. I do not know ho- far north this severe damage extends. Damage to pecan trees by May- beetles has also been reported from other sections- of the State, especially from one property at Jackson in Hinds County."
CUTWORMS (Noctuidae)
Indiana J. J. Davis (May 25): Cutworms damaged a six acre field of onions at
Angola on May 12, and pansies at "Richmond on May 18. Reported as abundant in sod fields being planted to corn from several sections of central and northern Indiana. (May 26): Reported today damaging corn at Delphi.
Iowa C. N, Ainslie (llay IS): There is much" complaint of damage by cutworms;
all sorts of garden plants, potatoes, and strawberries are being injured. These larvae are still small and immature.
-91-
Ncw Mexico J. R. Douglass (May 21); Complr.ints have been received from farmers throughout the Estancia Valley concerning the great number of cutworms present. No commercially important damage has been noted, as corn is just coming up and beans are being planted at the present time. Eighty thousand acres of cultivated land lay idiealast season on account of the drought.
BLACK CUTWORM (Agrotis ypsilon Rott. )
Mississippi R. W« Harned (May 13): Cutworms found damaging sweet peppers at Pascagoula, Miss., by R. P. Colmer on May 3, have been identified by S. E. Crumb of the Bureau of Entomology as the greasy cutworm, (Agrotis vpsilon).
ARMY CUTWORM (Chorizagrotis auxiliaris Grote)
Kansas J. ¥. McColloch (May 20) : During the past month injury to wheat has been reported from Smith, Rice, and Ellis Counties; to alfalfa in Wabaunsee, Saline, and Dickinson Counties; and to gardens in Dickinson and Rooks Counties.
Nebraska M. H. Swenk (April 25-May 25) : The army cutworm has been
reported from Perkins, Sheridan and Knox Counties. In Sheridan County these cutworms infested alfalfa to such an extent that some fields were plowed up and planted to other crops. In Lincoln, during the warm nights of May 23 and 2U, there were literally thousands of the adults of Chorigagrotis auxiliaris flying daring the evenings. They were especially noticeable on flowers of peony and iris, and caused much annoyance by getting in between the windows and screens of houses.
YELLOW-STRIPED ARMYW0RM (Prodenia ornithogalli Guen.)?
California E„ A. McGregor (May 18): During the first two weeks of May there has been a very conspicuous occurrence of the yellow- striped armyworm, Prodenia pracfica Grote. At first the cater- pillars confined their attacks to certain common native weeds, and at the height of occurrence in the open fields there was nearly one larva per square foot of ground. As native plants dried up following the end of the rainy season, the armyworms began to migrate. It was of much interest to note that the great bulk of the individuals pursued a common direction, namely, from the southeast to the northwest. This seems remarkable for an immature stage.
One young orange grove --'hich ley to the northwest of a large pasture soon became rather badly defoliated by the ^'ork of the migrating worms. The owner combatted the pest by placing arsenic-treated oranges at the base of each young tree. After 2^ hours there was an aver cage of about 30 dead armyworms near the foot of each tree. The treatment seemed to give protection until the worst of the migration was over.
The migration extended over a rather large extent of the country.
-92-
VARIEGATED CUTWORM (Lycophotia margaritosa saucia Hb. )
Mississippi R. W. Harned (May 27): This species is doing serious damage in the Delta or western section of Mississippi. On May 20, T. Y. Williford, County Agent, Cleveland, Bolivar County, Miss. , mailed to us several dozen specimens of the Variegated cutworm. At the same time he ^rote: n3ig collection of worms taken from alfalfa field "'here they had denuded stems of all leaves, moved across into gardens and cotton fields, ate up Irish potatoes, cabbage, tomatoes, onion plants, cotton, and everything in their way. Do their ^ork mostly at night, hiding in the day in cracks of ground or under piles of alfalfa or in shady places. Dug up some of them from k inches under ground, showing change to lighter color or losing some of dark color. The red looking pupae were found at same place about same distance under soil. 7e thought possibly they "ere pupae of the worms. The worms have not bothered s^eet clover,"
On May 19 Inspector D, W. Grimes, Leland, Miss., sent in a supply of these cutworms stating that they were causing severe damage in places. The specimens that he sent were collected in alfalfa field. Fornpositive determination a number of the insects from Mr. T7illiford were sent to S. 3. Crumb of the U. S. Bureau of Entomology, ^ho identified them as this species.
On May 26 a correspondent at Clark sdale in Coahoma County sent a supply of the variegated cutworms to us with a report that they are feeding on alfalfa and unon leaving the alfalfa field are eating cotton clean as they go. This makes three counties from ^hich these insects have been reported as serious during the past week. These counties, Washington, Bolivar, and Coahoma, are in a ro^ along the Mississippi River in the western part of the State. They are in the center of the Delta, the richest section of the State.
Texas F, L. Thomas (May 12): Originating in alfalfa and spreading
into young cotton near Ennis in Ellis County, absolutely cleaning 7 acres of ootton, and causing much damage to the alfalfa.
WIREWCRMS (Elateridae)
Indiana J. J. Davis (May 25) : Reported abundant in sod and other
fields but no damage yet this season excepting in one instance at Brookville, May 15, where they ^ere heavily infesting sprouting potatoes. An S-acre field of onions reported as practically destroyed by wireworms in Steuben County.
Miscouri L. Baseman (May 21): Farmers arc reporting stands of corn on 50 and 75 acre plantings destroyed. The pest is proving a real problem on many farms,, and is widely distributed in this State.
A. C. Burrill (May 22): Field corn is not up but local gardens suffer from this pest in many places in Jefferson City. I suppose
-93-
that late season and weak corn, only a few inches high, &ave intensified the gardeners1 troubles.
Kansas J. 1". McColloch (May lU) : Germinating seed corn has been seriously injured by wireworras at Fort Scott, Abilene, 'Vhite City, and Ogdfin....In many fields it has been neeessary to replant^
CEREAL AND FORAGE -CROP INSECTS
WHEAT
HESSIAN FLY (Phytoohaga destructor Say)
Indiana J. J. Davis (May 25): Hessian flies were out laying eggs on May
3 at La Fayette.
Missouri L. Haseman (May 21): In central Missouri it is practically im-
ppssible to find this insect.
Kansas Kansas Crop Report of the State Board of Agriculture (April 10):
Attention is called to the fact that the autumn infestation of the Hessian fly was much greater after seeding last fall than it was in the fall preceding the 192H harvest. The potential menace from this source is therefore greater now than it mag two years ago. In some south-central counties field examination on acreages containing much volunteefc or in early seeded fields shows as many as 10 or 12 flies in the flaxseed stage this spring. Weather conditions during the egg-laying time and during the hatch of the first brood will have much to do with the amount of this year's fly damage,
CHINCH BUG (Blissus leucouterus Say)
Illinois W» p. Flint (May 18): Examinations in small grain indicate-that chinch bugs will cause damage in local areas in some 50 counties in the central and south^central parts of Illinois. Egg laying is just starting, but no young bugs have been observed in the field to date. The weather thus far has been rather dry and favorable to the development of the chinch bugs.
L. Haseman (May 21): No reports of chinch bugs in wheat have been received to date,
J. W, McColloch (April 13): I also have the report of the county agent of Washington County relative to the chinch-bug situation, in which he states that all bunch grass which was not burned over last fall contains a large number of chinch bugs, and there is danger of considerable injury this year.
Mississippi R, W. Harned (May 12): On May 12 chinch bugs were collected on
corn at Coldwater, Tate County, by Inspector T. F. McGehee, These insects are reported as beooming very abundant on corn in portions of Tate, DcSoto, and Marshall Counties.
Complaints in regard to chinch bugs were not unexpected because

the stumers of 192U and 1925 have "been exceptionally dry throughout the northern rart of Mississippi, h nj 3omplaints in regard to chinch bugs were received during V. summer of 1924 and a still 3,arger number ^ere received during 1925- (May 22): A complaint has been received in regard to chinch bugs damaging corn in Sunflower County, 'lies., recently. A previous report in regard to those insects damaging corn and sugarcane in the northern part of the St?. to was submitted several days are.
CORK
SEED-CORN BhEmLE (Agonoderne pal lines Fab.)
Missouri A„ C Burr ill (Thy 22): At Jefferson City heavy emergence
of adult's at street and hor.se lights the first half of May was reported. Always very abundant in the Missouri and Mississippi Valleys rrithin this State.
COM ROOT TEB1QR.M (Crambus cali-rinosellua Clem. )
West Virginia W„ E. Rumsey (May 2h) : We have a report from Heater, 3raxton County, that the com root webworm is quite a serious pest in that locality.

AffiftTRKBM (Cirphis vni-uncta Ha-. )
South Carolina J. o. Pepper (May 12) : Specimens of the true armyworm have been received from Beaufort County ani reported as feeding on small grains.
Indiana H. F. Diet2 (May 1?): Armyrform moths ,vere first taken at lights
at Indianapolis en May 2.
J. J. Davis (May 25): Armyworm moths have been unusually abundant. They -ere reported common at lights and 1 ch
blossoms the latter part of April in southern Indiana. Reports of their abundance on apricot flowers en May 2 at G 3wa
in central Indiana '-ere also received and they -ere observed crommon at lights at La Fayette about the same time. Mo report of army-arms yet received.

Indiana J. J. Davis- 'Hay 25) : -Reported abundant and injuring corn at Eusliville, May 19.
ALFALFA '
ALFALFA WEEVIL (Phytcncmus posticus Gyll,)
Wyoming C» L. Corkins ('lay g).: Wqeyiis are abundant only in a few
fields. Egg laying has started, One small larva was taken. At Careyhurst the average number of eggs per ICO fresh stems .- on May 5 was 13*3; the number, of adult weevils per IOC strokes of the" net was 3.7.
A3? AlT0IvlALA.(A2iomala binotata Gyll. )
Kansas J. '.7* McColloch (May 7): Adults were received from Holton

PEa APHID (Ulir.oia pi si Kal t. )
Kansas J. ™. McColloch (May 20): There has been a rather general out-
break of the pea aphid, in.. the alfalfa fields of . the State. The cold backward spring has been favorable for the development of the aphid's. The outbreak has "ooea of interest because of its spread westward in the State. The heaviest loss ^as probably in the southwestern part of the State.
FALL ABMTW'GRM (laphygma f.-ugi-p&rda S. & A.)
Florida J, R.. Watson (May 15): A. good many reports are reaching the
office concerning the depredations of the fall armyworm, mostly
on grcirs.
CLOVER LEAP WEEVIL (Hyp era punctata Fab.)
Illinois W, P. Flint, (May 18): The clover leaf weevil, ~hich earlier
. . in the season threatened to be quite destructive in the astern
sections of Illinois, has caused very little damage, the insects having been' largely destroyed by the fungus disease which frequently attacks the larvae.
Kansas J. W. McColloch (May 20): Larvae and cocoons of the clover
leaf weevil have been received from e number of localities in the State,, southeastern quarter, during the past month. In no case has serious injury been reported.
Indiana J0 J. Davis (May 25):" The clover leaf weevil is not so generally
abundant as usual. Reports of injury to little red clever and to sweet clover were received. from the southern sections of ... the State. (May 26): Two reports of heavy infestations for north-central Indiana -'ere received today.

ROSY APPI3 APHID (Anur aphis rcseus Baker)
G. F. MacLeod (April 21): This aphid occurs generally in younger plantings and is abundant enough in Perks County to make control practices necessary.
H. E. Eodgkiss (April 30): This succies is not present in large numbers over the entire area but occurs especially in old orchards. In the majority of these it has been necessary to make a special point to effect control although in a few of them the infestation is comparatively small. Reported from Snyder, Juniata, Union, Northumberland , end Dauphin Counties.
J.O.Pepper (May 10): This insect recently appe r " in largo numbers and has caused the leaves of apple to curl. However, the natural enemies ar 1 holding it under control at nreseht.
WOOLLY APPLE APHID (Eriosomr lanifcrum Hausm. )
J.O.Pepper (May 15): The woolly apple aphid is abundant in the college orchard this year.
S. ".;„ Mendenhall (May 5): I find the appearance of -voolly apple

aphids en the English and American elms in the parks in Dayton, Ohio* They seem to he cradling on the bodies of the trees.
3R0'.7H SOFT SCALE (Lecanium coryli L« )
Washington Arthur Frank (May .1); Infestation hy Lecrn iurn coryli is present
in Whatcom bounty and also King County and about the City of Seattle. This insect has escaped from British Columbia into this country, as.. they had a very severe outbreak in 1924~>25» At present the infestations occur upon apples, pears, prunes, cherries, gooseberries, currants, raspberries and plums. The pest has escaped into the native vegetation at several places and I have reports of its presence uuon the native timber.
CODLING MOTH (-Carpocaosa nc-onelln Lb)
Massachusetts A,* I. Bourne (May 21): The codling moth was reported to have begun pupation early in May,, Mr<, Whitcomb in Middlesex County observed the first pupation on May 2, Here at Amherst the first .pupation was noted four or five da;ys later., -
Indiana J„ J* Davis (May 25): The codling moth situation is unchanged,
\There proper spray methods are practised no trouble is evident. Examination in an orchard at Mitchell showed that about a third or fourth of the overwintering larvae had pupated. .Emergence records; indicate that the regular spraying schedule for 1h e first brood of codling moth worms is applicable this year.
Illinois W.P.Flint (May IS): Emergence of codling moth adults was
first observed in southern Illinois on May Ss and adults are now appearing in both central and southern sections of the State. Aprarently the young worms will start entering the apples about two weeks later this season than was the case in 1925.
Missouri L. Baseman (May 21 )• The pest v-as slow emerging as the moth,
though in central Missouri. moths have been emerging since May 13 in breeding cages. Moths -ere on wing in the orchard on May 20,

EASTERN TEHT CATERPILLAR (Mai aco soma americana Fab. )
AB I« Bourne (May 21): The apple tent caterpillars, which aero hatching out just about the time of my last report, have fully justified cur early predictions as to their relative abundance, Reports which have come in from the eastern part of the State invariably found this insect to be considerably less abundant than for several years past. Here in the western half of the State, however, the pest is rather on the increase.

A. I. Bourne (M-.y 21): The ap-oie red bugs as yet have failed to make their appearance at, all conspicuous. Over the State as a whole these appear to bj much scarcer than normal.
APPLE LEAF 301 1 ER (Empoasca rrali Le3 , )
A. I. Bourne (May 21): The apnle -leafhoppere pare rather conspicuous as yet by their absence. All 'these species rr-j prnctiaally absent from our orchards; at least they have not m;" le their ^ye-irance up to this time. In fact,, there is such a scarci ty of aphids and loafhopners that many gro-7. rs did not include nicotine in their pink spray, nor do they contemplate the- use of it in. the.calyz.

Mr. 7ftiitconib,who is locate! in the eastern part of the State, reports finding them hatching some days earlier than this, and that by May 7 close to [30 per cent of the eggs hi d batched, indicating that in the particular region of Jliddlesex County the overwintering ergs hatched three or four days earlier than this date., On the whole it appears that there is a slight increase in the abundance of this pest this present season as judged by reports •■•hich we have received thus far,
Connecticut M. P. Zappe (Kay IS): Mites are ^<ary plentiful in New Haven and Fairfield Counties on unsprayed trees and also on somo sprayed trees that had not been very thoroughly sprayed with miscible oil at the delayed dormant period.
New York C. R. Crosby and assistants: infestations in Ulster County,

PSAS THRIFS (faeniothrips incensequens Uzel )
Sew York C. R. Crosby and assistants: In Orange County 3 on April 17,
only a few specimens were found, whereas in Columbia County, on April 23, thrips appeared in numbers on pears, in fact on all species of fruit trees. In Ulster County a few individuals vrere found on April 20. Their numbers increased slightly on April 21. The buds ™ere sufficient.lv ooen tc allov: the insects

In Dutchess County, on April 23, these insects were observed in small numbers. In Orange County they emerged in some numbers on April 21 and 22. As high as ^0 individuals prr "bud -rerc observed. It appears that no effective spray can be applied to control the adults this season.
PE<iR ISYLIA (Psylls pyri I.)
Massachusetts a„ I. Bourne (May 21): The pear psylla has been found to be
about as abundant as for the last few years, but we are finding that oviposit! on seems to be extending over a io"A:er period and That both the adults and ne-ly In id eggs car be found much later in the season than is normally the case , This somewhat complicates control measures since the lime- sulphur tr :ment applied at the time of the "pink" on the pears has not given as good control as normally is the case, owing to the fact that so many of the psyllas have continued laying after the time at which this spray could be applied safely.
New York C, R. Crosby and assistants: The pear psylla is commonly found
in orchards in Dutchess County at this time, but oviposit ion did not start until April 1}". In Ulster County small numbers of eggs have been laid in most orchards and large numbers have been found near the Hudson Biver on April 1C. In Grange County on April 17 oviposit ion washheavy*

On May 11, after visiting the infested a3M53i,he wrote: "The . - e station seems to be confined to a section of the county next to Pearl River, but it is the most 'severe case of insect injury that I have seen, en pecans* The trees that these t"dgs mere taken from are 30 years old or older and almost every twig is infested. The specimens that I am sending are from the property of J". Route A* Poplarville, who states that he has noticed the beetles for three years. Tea can find signs on the -ccd th snding
where injury was done last year. I want to scout the infestation in the county, I certainly hope that It will be confined to a small section for it -ill cause great loss if it spreads over the count; .
trees that we have found infested so far are adjacent to hundreds of acres of woodland, and the hickory trecti in the woods are infested. f|

May 12, C, M„ Chance, Inspector for the State Plant Beard, went to Lincoln County to investigate this outbreak,. He and Mr, Renfrow visited the farm; of J. HB Hoggatt and" .Will Haley. He reported: ''We found that this insect is doing a great deal of damage, principally
use cf the fact that the larva bores the shoots on which the nut clusters form, thereby cutting off the fruit and foliage. On Mr. Koggatt's farm, we found one tree that had shed a good part of its foliage, and apparently 90 per cent or more of the shoots left were infested. The owner expects this tree to die. Mr. Hoggatt told ma that his trees were about ten years old f but he had only noticed this injury during the pist three years. He said that it had
en worse each year and that this reason it -us much worse than Mr. Hoggatt suid that the -^ork of this insect was much more
rent early in the season, and that he did not remember it doing rou«h ] mage later in the summer, in another grove about 100 yards from the Hoggatt place, tl •< trees were found to be badly infested. In a "rove inspected 3 miles away no injury from this inject - found."

PECAiT HUT CaSE BEARER (Acrobasis hebescella Hulst)
Texas H* Se Adair (April 27): The first feeding of overwintering larvae
at Brownwood of the pecan nut case bearer was observed March 23 on the swelling buds of the pecan. Cool weather immediately following this date checked the growth of the pecan trees somewhat and consequently checked the emergence of larvae from hibernation, since the emergence of the larvae coincides ~dth the swelling and opening of the pecan buds. Recently much feeding of the larvae has been observed and the larvae appear much more numerous.

Florida 0*. R« Watson (May 1^): This insect has been much less abundant
-ioS-
than last yerr. The damage has been much less then ].0 per cent of that of last year's attack*' The relative scarcity this year is apparently due mostly to the fact that the' steady cold of last -inter prevented citrus trees f>*om putting out any ne^ te^er growth, with the result that ^he aphid s which can net live on mature foliage were reduced to small numbers, Chen the growth did come out it cane out rapidly and the aobids were not able to thoroughly infest it before it beefne mature again. The big flush of spring growth, in eluding a heavy setting of fruit, and drought has again put the trees into a very thorough dormancy as far as ne'7 growth is concerned end the aphids are very scarce.
Louisiana ■ T„ F0 Catchings (April 1} ) : In four groves inspected at the Buras,
all ne" growth was found infested with aphids, and the leaves "beginning to curl. Grapefruit, navel oranges, and Louisiana sweet oranges ^ere not infested. Citrus nobn_i_s deliciosa and Citrus r.obilis unshiu were being attacked by this insect,

LEU!? ROLLER (Tortricidae)
Ohio E. \7, M&ndenhall (hay U): These insects are a menace to plants
in greenhouses and a re very hard to eradicate. Paris green or arsenate of lead seems most effective. They seem worse some years than others. They arc very bad this year and the greenhouse men are busy fighting them.
A DIGGER SEE (Andrena vicina Smith)
Nev: York S. P. Felt (May ?6): A digger be em provisionally identified

Indiana H« F» Diets (May IS): la a seri ous greenhouse pest at this
time "because during- the dark weather that we have had since October, 1925* florists were unable tc use customary syringing under strong pressure. As a result heavy infestations of this pest are common on rosos, carnations, gladioli, and Sweet peas.
Mississippi R. TC. Earned (Hay 22): Rod spider injury to rose has been
reported from Natchez in Adams County, and from Carroll ton in Carroll County a complaint has "been received in regard to red spider injury to carnation.

midge have been found during the past two months at Indianapolis Kokomo, la Fayette, Newcastle, North Manchester, and Richmond. The only heavy infestations of th is re st .-./ere at Kokomo and Newcastle in greenhouses where no control measures were taken. The method of shearing off the tops of the stock plants to the ground line or slightly below, keeping the plants rather dry until growth starts again, has proved an effective control of midge if all stock plants are thvis treated. Better plants than usual have been produced through this method.
ONION THRIPS (Thrips. tabaci L. )
