A MANUAL OF DAiNGEROUS LNSECTS LIKELY TO BE INTRO-
DUCED IN THE UNITED STATES THROUGH IMPORTATIONS.
This publication has ])een prepared in the Bureau of Entomology
at the request of and in cooperation with the Federal Horticultural
Board to supply such information as is required by its officers
and others in the enforcement of c|uarantines and 'the safe-
guarding of this country against foreign insect pests. It should
assist materially in preventing the introduction of additional pests
like the gipsy moth, boll weevil, and alfalfa weevil. Only a brief
sketch can be given of each of the more important species. The
plants making up the commerce in vegetable products are arranged
alphabetically by the American common name, with the scientific
name following. It is believed that this arrangement is most con-
venient for inspectors. A brief sketch of certain important facts
concerning each plant is also given.
The arrangement under each plant of the insects in two or more
categories, A, B, etc., is merely one of convenience. Under A are
grouped the better known insects, or those concerning which there
is available literature. This category especially contains pests
which are easily imported. Under B are listed many important
pests, possibly sometimes more' important than those listed in A and
often just as readily introduced. They are merely listed because
full descriptive matter was not available and for other similar reasons.
In later editions probably many of these pests will merit fuller
discussion.
It is not to be expected that inspectors will attempt to make final
determinations with the aid of this work. In fact, it would be very
unwise to do so. The book is merely to indicate to inspectors and
entomologists the insects likely to be found associated with impor-
tations.
The references to foreign literature under the species give the best
or most easily available source of additional information. Tables
and keys to species could not possibly be included in a work of this
kind. It is expected that the inspector, on finding important insects
not already familiar to him, will immediately transmit specimens to
the Bureau of Entomology at Washington, D. C, for reference to the
proper authorities or to other competent specialists in the groups to
which the insects belong.

4 A MANIAL OF DANGEROl'S INSECTS.
Tliis compilatioji Avas only possil)lo by tJio cooperation of all the
ilivisions of the Bureau of Entomology, some of which prepared the
matter in the form in which it now appears. The editor therefore
wishes to acknowledge tlie assistance; of Messrs. C. L. Marlatt, W. D.
Hunter. A. 1). Hopkins, the late F. M. Webster, F. H. Chittenden,
A. L. Quaintance, W. R. Walton, E. R. Sasscer, Jacob Kotinsky,
Dwight Isely, II. L. Sanford, and R. W. Rust for the collection of the
notes on the insect enemies of the crops investigated by them,
and of Messrs. W. R. Walton, Harry B. Bradford, and the late J. F.
Strauss in the preparation of the illustrations.
The lists of insects included in this manual are necessarily incom-
plet(\ and no doubt ijuportant species have been omitted. Fre-
(piently the lit(>ratur(> on dangerous species is so meager as to make
it impossible to conclude as to the importance^ of the species.
R(>garding the nomenclat\n-e, it should be remembered that this
Avork is strictly a compilation. Many of the names will undoubtedly
be changed as the result of future studies. The ones used, however,
are the ones curr(>nt in European literature". To have attempted to
nuik(> the nomenclature more exact would have involved practically
the revision of many hirge groups of insects. This would have been
entirely impracticable and would have delayed publication of the
manual for years. Moreover it would have resulted in a publication
"which inspectors would have had diiliculty in using on account of the
fact that the literature accessible to them wouhl liave, in many
cases, used other names. In order to make future editions of this
handbook more useful, the bureau will be greatly obliged for criticism,
additions, and reconnnendations as to treatment.
The majority of the insect pests in the Ignited States wiiicJi now
occasion the greatest damage to orchard, field, and garden crops and
to stored products and in homes, etc., are of foreign origin, and were
introduced with the host plants or accidentally in the course of com-
merce. Such introductions of new pests are going on all the time,
as illustrated by such recent arrivals as the Argentine ant in New
Orleans and the alfalfa leaf weevil in Utah. The list of over 100
introduced insect pests given below illustrates the nature of the
most important of these introductions in the past. This handbook
contains the names of hundreds of other insects which now occur in
different parts of the world and which are liable to be introduced at
any time with nursery stock or in merchandise or as accidental guests
or stowaways on ships or in baggage. It also includes a considerable
number of introduced pests which are not now generally distributed
and whicli therefore should be guarded against both as to further
entry and to furtluM- distribution within the United States.
Throughout the work species which have been introduc(Ml into the
United States an* marked witli an ast(M'isk (jtc") and the fact of the
LIST OF INTRODUCED FOREIGN INSECTS. 5
introduction is montionod. Man_y of the most important introduced
insects are omitted because they are now so generally distributed
that the importation of a few additional individuals will hare no
effect upon the existing economic conditions.

INSECTS SPECIALLY LIABLE TO IMPORTATION AT ANY
TIME.
There are certain groups of insects which are uniformly injurious
and can not therefore be given full justice in a bulletin of this type.
These insects should be especially guarded against and excluded on
general principles, whether incriminating evidence is found or not.
TERMITES (TERMITID^).
There have been several cases of introduction of termites into the United States,
notable among which was the importation of Leucotermes lucifugus Rossi in packing
boxes from Germany. The termites are uniformly injurious to wood and plant
growth and may be imported in any type of wood, whether in the form of nursery
stock, lumber, or manufactured product. A list of species is to be found in Wyts-
man's Genera Insectorum by Desneux (1903).
THRIPS (THYSANOPTERA).
The tiny fringe-winged thrips are very destructive to many crops, and should
always be guarded against.
SCALE INSECTS (COCCIDiE).
These tiny insects are inconspicuous and the greatest of care is necessary on the
part of inspectors to prevent their introduction. This family may be considered, as
a whole, a most undesirable group of insects. Many species have akeady been in-
troduced and become serious pests. Reference to Mrs. Fernald's Catalogue of Coc-
cidae as well as Technical Bulletins 12 and 16 of the Bureau of Entomology will
give full data as to literature. L. Lindinger, in his "Die Scliildlause (Coccidee),"
gives tables to the species of European scale insects attacking each plant. All names
of scale insects used in tliis bulletin have been verified by Mr. E. R. Sasscer. Several
genera of scales are illustrated on plates i-v to assist in determination. Some of the
species illustrated are not treated in the text, although congeneric species are.
WHITE FLIES (ALEYRODID^E).
The tiny white flies are very apt to slip in past even a zealous inspector. The
flattened scalelike larv;e of some species look so much like the plant tissue that they are
easily overlooked. The active little white-winged adults fly so quickly that rough
handling would tend merely to disperse them and increase the dangers of introduction.
Kirkaldy in 1907 issued a world checklist in Bulletin 2, Hawaii Board of Commis-
sioners Agriculture and Forestry. (See Technical Bull. 27, of the Bureau of Ento-
mology and Proc. U. S. Nat. Mus., No. 2156.)
RED SPIDERS; MITES (ACARINA).
These tiny eight-legged creatures are not insects, but so closely related that they
are generally treated as such. The red spiders are exceedingly minute and occur
on almost every type of vegetation. As their rate of multiplication is very rapid
S A MANUAL OF DANGEROUS INSECTS.
they Jiave becomo serious pests to agriculture. Tliere are a number of four-legged
blister mites of great importance and yet so small that they can only be seen with a
very high power lens.
BARKBEETLES (SUPERFAMILY SCOLYTOIDEA: FAMILIES IPID^,
SCOLYTOPLATYPODID.*, SCOLYTID^, AN^D PLATYPODID^).
All of the bark beetles, ambrosia battles and other members of this family are
more or less injurious to tree growth, forest products, tree seeds, fruits, etc., and
species known to bo injurious must be carefully guarded against. These beetles
are small, cylindrical with elbowed and clubbed antenna?. The head is without
or with very short beak and the subraentum is without a gular peduncle. In Ipidae
and Scolytidae (Hopkins'.s classification) the first joint of the tarsus is shorter than the
others combined, while in Platypodidte the first joint is as long or longer than the
others. They all bore in the plant tissue to deposit their eggs and their burrows
or galleries are characteristic of groups, genera, and species. The food consists of
plant tissue except in the ambrosia beetles where it consists of so-called ambrosia
fungi. Genera Insectorum has issued a fascicle on Ipid9B=Superfamily Scolytoidea
of Hopkins,' with catalogue of species of the world.
BEAN WEEVILS (MYLABRIDiE— BRUCHIDJi:, LABIID^).
The seed weevils or bruchid;^ brood almcst entirely in the seeds of plants, especially
of tho'bean and pea family. They are uniformly injurious and .should 1)0 excluded.
These beetles are usually small and either oval or elongate, with the head carried in a
downward position and with the anteniue often iJectinate or plumose. The elytra do
not conipletoly cover the abdomen. A catalogue of the Mylabrid;i3 (Bruchidic) has
been issued by Junk.
CUTWORMS; ARMY WORMS (NOCTUID^).
Several species of cutworms and army worms have already become world wide in
their distribution through their strong flj'ing ability and by commerce. As the larvse
are very generally destructive and not at all exclusive in food habits, they need to be
carelully guarded against. Lar^■oe may bo transported anywhere on the ships. Cirphis
imipuyicla ITaworth, the army worm; Spodoptera mmintia Boisduval, the grass army
■worm, and Agrotis ypsilon Kottonburg, the greasy cutworm, are practically co.s-
mopolitan. A discussion of most of the injurious species will be found in Sorauer's
Handl)uch dor Pflanzenkrankheiten, 3d od., 1913, vol. 3, pp. 348-374.
WEEVILS. RHYNCHOPHORA— COLEOPTERA.
The oxp(>rioncc of the last few ^^ears in the quarantine of horticul-
tural products has shown that one of the groups most hkely to intro-
duction is the group of weevils which comprise a large section of the
order Coleoptera.
Owing to the development of nnin}' species of weevils in the roots,
stems, and fruit of almost evt^r}^ type of plant known, it is very easy
to introduce them in immatm-e stages in such a manner that they may
take hold and attack the introduced plant. Owing to the necessity
of determining practically all of the weevils introduced by a search
through foreign literature a majority of the species so far introduced

hav<3 not H^con dotcnuiiuKl or described. For this reason many im-
portant species are not included in the present edition.
The larvae of weevils are white or yellowish with a dark head
shield and are usually found in a more or less curved position. Most of
them are ratli(>r robust and with a very few exceptions have no legs
or rudiments thereof.
The pupa can alwa3's be distinguished by the presence of the beak
lying flattened between the legs.
The adult weevils are distinguished b\ the prolongation of the head
into a beak. This nuiy be ver}' short and broad or very long and
slender. They are furthermore characterized by having the tarsi
four-jointed. Inspectors are urged to take every possible precaution
against the introduction of any species of weevils and where imnui-
ture or adult stages arc found they should immediate^ place them in.
akoliol and send them to Washington for determination.

ALDER.
(Alnus spp. Family Betulacese.)
Hardy ornamental trees and shrubs grown in Asia, Europe, North America, and
South America. Alnus rubra is the most important timber tree. The genus is not
attacked by many very serious pests, but any of the wood borers, especially, might
become serious when transported to another country in nursery stock. Several
pests have gained admission to the United States in some manner. These are indicated
by an asterisk.

(Mcdicdgo fiutird liiiinaju.s. l'':uiuly Lctiuiiiinusse.)
Alfalfa is a s1aj)l(' foray;o i)laiit in many jtarts of the world, being grown cxIoiiMively
in EuroiJO, Asia, and South America, as well as in this country. Excej)t in Hhij)nient8
of iiay, the only danger of introducing pe.sts is with the seed. Some very imjiortant
European pests of alfalfa have in .some manner already readied this country and are
<loing serious damage.
Most insects attacking cIo\(;r are ])otential alfalfa pests and it is therefore advisable
to consult the list of clover pests when dealing with alfalfa.

only 1)6 propagated from suckers or sprouts there is danger of introducing pests into
the country in this manner. The banana is grown very extensively in the Southern
States as a hedge plant. The compact nature of the fruit l)unches makes it possi le for
many insects of considerable size to find entrance into the country in the bunches as
well as in the fruit itself.
A. BETTER KNOWN BANANA PESTS LIKELY TO BE IMPORTED.
Cosmopolites sordidus Germar (Splienophorus.)
(Banana Root Borer. Calandridse; Coleoptera.)
Hosts: Banana (all varieties), sugar cane.
Injury: Serioxis pest to young banana plants in Fiji.

BEAN.
(Phaseolus vulgaris. Family Leguminosse.)
This species includes the kidney, common field, garden, snap, and string beans.
It is probably of tropical American origin. The beans are an article of commerce and
very likely to introduce pests.
BROAD BEAN.
(Viciafaba. Family Leguminosae.)
The broad bean is a native of Asia, but is grown extensively in Europe and North
America, especially as a food for domestic animals and for human consumption.
The beans are an article of commerce and quite likely to introduce pests.
LIMA BEAN.
{Phaseolus lunatas. Family Leguminosse.)
The lima or sugar beans are native to South America. They are articles of com-
merce and quite likely to introduce pests.
A. BETTER KNOWN BEAN INSECTS LIKELY TO BE IMPORTED.
Mylabris (Bruchus) spp., etc.
(Bean and Pea Weevils. Mylabridse [Bruchidse]. Coleoptera.)
Many of the wee^dls attacking beans are cosmopolitan and have been introduced
into the United States. The fact that they breed in perfectly dry stored beans makes
their distribution very easy.

BEET INSECTS. 41
BEET; MANGELWURZEL OR MANGOLD; SUGAR BEET; CHARD.
{Beta vulgaris Linnaeas. Family Chenopodiacese.)
The beet and its varieties are grown from seed. The varieties have been developed
either for their roots or their foliage, which are edible. A race of showy foliage beets
has been developed which make excellent flower-garden borders. The species occurs
in America, Europe, and as far east as Persia, and the Caspian Sea. Insects are most
likely to be introduced in shipments of beet roots.

CLOVEK.
(Trifolium spp. Family Legiiminosae.)
There are many species of clovers used as forage crops in various parts of the world.
Although clover is usually only imported as seed, several very serious foliage pests
have been introduced from Europe.
The lasiocampid moth, Lasiocavipa trifoUi Ep., of Europe and Asia Minor, is in-
jurious to clover. Many weevils of the genus Sitona not mentioned below are in-
jurious to clover in Europe. They breed at the roots, but several have been imported
into the United States. The weevils of the genus Hypera (Phytonomus) are equally
dangerous to clovers. They breed externally on the foliage. Several European
species have established strong colonies in tliis country. The weevils of the genua
Apion (e. g. ^1. apricans Herbst) often breed in the heads of clovers and many of
them are very dangerous. (For Agriotes lineatus Linnaeus see Tobacco.)

other species are of similar form but dif-
ferent colors of brown, gray, or green. The larvae feed externally on the leaves and
pupate in silken cocoons.

COFFEE.
(Coffea arabica hinn9su8; Coffea liherica 'Hiem. Family Rubiaceae.)
Coffee is grown in Africa, Asia, Central America, South America, and man>- of the
islands of the Pacific and Atlantic. Although not grown in the United States proper,
it is an important product of Porto Rico, Hawaii, and the Philippines. The importa-
tions of the beans into this country are enormous. Where beans or seedlings are
imported into the Territories above mentioned, there is danger of introducing noxious
insects

hatch within 4 to 6 days, live within the leaf about 3 weeks, and then leave the inte-
rior of the leaf through the upper epidermis and form a web, pupating on under sur-
face of the leaf. The adult hatches in from 3 to 7 days.

CONIFERS.
(Family Pinacese.)
Fig. 35. — Pine bark beetle (Xylotrechus quad-
rives): Adult. (Maxwell-Lefroy.)
Under this beading are treated the insect
pests of Douglas spruce (Pseudotsuga), fir
(Abies), hemlock spruce (Tsuga), larch (Larix), pine (Piniis), and spruce (Picea).
This grouping is due to the fact that these trees have so many pests in common
and also because of a confusion in foreign and home literature of the names pine,
spruce, and fir.

CORN; MAIZE.
{Zca mays Linnseus. Family Graminese.)
Although the greater part of our commerce in corn is in the nature of exports, there
are always likely to be imports of seed corn from various parts of the world. Corn
is probably American in origin, and consequently there are few foreign pests not
already widely distributed in the country.

sunflower.
Injury: Although primarily a maize pest, it is becoming quite a serious enemy of
fruit trees in Cleveland District, Queensland. Breeds in pods of castor bean and
cacao, and heads of sunflower in India.
Description and biology: Adult measures about 24 mm. in wing expanse; color pale
orange yellow, marked with numerous black dots on wings and body. Egg presum-
ably deposited on leaf stalk near or at point of junction with main stem or young fruit;
larva on hatching penetrates into the hollow stalk or fruit, and after feeding for a time
bores into the crown, in which it remains until ready to pupate. On leaving the
crown of the fruit it crawls to some convenient crevice and constructs a loose silken
web under which it transforms to a reddish brown pupa.

COTTON.
{Gossypium spp. Malvaceae. ^
Many species of fiber yielding cotton are cultivated in various parts of the world,
and the fiber is a very important article of world commerce. The great impetus given
to seed selection in recent years has also caused considerable commerce in the various
varieties of seed for planting. Practically the only serious possibility of importing
cotton insects is connected with the seed and with lint when not thoroughly cleaned
of seed. There is also some danger of injurious insects finding refuge behind the
bagging of the bales. Owing to these dangers the Federal Horticultural Board has
forbidden the importation of cotton seed except through the Department of Agricul-
ture, and has placed restrictions on the importation of foreign baled cotton.
The cotton plant is one of the most severely attacked cultivated plants, having a
very long list of injurious insects. Although the majority
of these insects are not liable to introduction, there is
always a possibility that they may find entrance into the
country in the folds of the bagging of bales or on some
food plant.

the ovipositor), with a wing expanse slightly over 25 mm. Color of body rust-yellow
or brownish yellow, with three sulphur-yellow longitudinal stripes on the thorax in
well preserved mature specimens. Wings clear tinted in part with a characteristic
pattern of yellow brown, the brown predominating on the basal half and extending
obliquely forward, being continued along the anterior margin in a broad streak to the
extreme tip of the wing; a clear sinuate basal zone involves the second basal cell,
the base of the discal and part of the first basal cell, and is followed by a detached spot

at the costa just beyond the tip of the first vein; on the discal half of the wing there
is a brown band in the shape of an inverted V, resting on the posterior margin and
extending through the first and second posterior cells; this V-shaped mark may be
independent, or its apex may be joined to the other brown zone. There is considerable
variation in the wing pattern, both as to intensity of coloring and detail of the pattern.
Immature specimens have the brown wing pattern much weaker; newly emerged ones
show hardly a trace of it. Female ovipositor stout, shorter than abdomen, tapered
jsegularly toward tip and covered with coarse black hairs; in mature specimens it is
subcylindrical, but in specimens not fully hardened it is flattened.

PALMS.
The palms yield some very important articles of commerce, such as coconuts
and dates, and are also considered very valuable as orna-
mental plants.
For convenience the pests of the coconut palm {Cocos
nucifera), the date palm (Phoenix dactylifera), the royal
palm (Oreodoxa regia), the sago palm {Cycas revoluta). and
the toddy palm (Phcenix sylvestris) are treated under this
heading.
A. BETTER KNOWN PALM INSECTS LIKELY TO BE
IMPORTED.
Aleurodicus destructor Maekie.
(CoconutWhite Fly. Aleyrodidse; Hemiptera.)
Host: Coconut palms.
Injury: Has the appearance of being a serious coconut
enemy.
Biology: Eggs are laid on undersurface of the leaflets,
where the young larvae locate. Life history much the
same as Dialeurodes dtri R. and H. (See Citrus.) (See

Levuana iridescens Bethune-Baker.
(The Coconut Leaf Moth. Zygsenidse; Lepidoptera.)
Hosts: Coconut palm and royal palm (Oreodoxa
regia) .
Injury: Larvte injurious to foliage, giving the trees a
sickly appearance.
Description and biology: Adult female, head and thorax
steel-blue; abdomen and legs ocherous, primary veins
deep unicolorous steel-blue, secondaries iridescent steel-
blue; wing expanse about 16 mm. Eggs deposited on
under surface of leaflets, usually near the base. Upon
hatching, which requires about 4 or 5 days, the larvae
begin feeding around the egg shell, gradually proceeding in
a longitudinal line up the leaf, nibbling on the epidermal
cells on the under surface of the leaflet; are full grown in
.3 or 4 weeks, when they return to the base of the leaves
and construct a white cocoon within which to pupate; the adults appear in about
7 days.
Distribution: Fiji.

color, brown ocher; head small, elytral strise finely punctate. Eggs deposited singly
on underside of leaflets in a small hole made by the adult; entire larval and pupal
periods spent in the leaf between the lower and upper epidermis. More injury is
occasioned by the larva than by the adult. Tissues which have been attacked soon
become brown and die. Egg stage about 32 days, and pupal stage about 7.5 days.
Distribution: Philippine Islands.

POTATO.
(Solunu'in tuberosum Linngeus. Family Solanacea?.)
Althougli we grow many potatoes in the United States there has been a very large
importation trade with other countries. Owing to the danger of introducing certain
diseases especially, the Federal Horticultural Board has placed restrictions on the im-
portation of potatoes. There are a number of important insect pests which need to
be guarded against almost as closely as the diseases.
A. BETTER KNOWN POTATO INSECTS LIKELY TO BE IMPORTED.
* Rhizoglyphus (Coepophagus) echinopus F. and R.
(Potato Root Mite. Tyroglyphidse ; Acarina.)
Hosts: Potato, parsnip, tulips, lilies, orchids, and many weeds. '
Injury: Very destructive to roots and tubers.
Description and biology: A very tiny mite which breeds in roots and is quite destruc-
tive. It may readily be transported with root crops.
Distribution: France, Italy, Portugal, Palestine, Chile, Australia, California.

RICE.
{Oryza sativa Linnaeus. Gramineae.)
Rice is still an important product for importation in spite of the steadily increasin<^
production in our own country. The principal sources of importation are Japan"
China, India, Mexico, and Honduras. The danger of importing rice insects is two-
fold, through the grain itself, husked or unhusked, and its original containers and
through nee stalks used in packing fragile articles of commerce. The similarity of rice
and grain insects lends importance to any rice pest introduced into the United States.

SUGAR CANE.
(Saccharum offidnarum Linnaeus. Family Gramineae.)
Sugar cane is an important product of the Southern States, Hawaii, Porto Rico, and
the Philippines. It is grown in many parts of the world. Owing, however, to the
great danger of transporting insect enemies in the seed cane, its importation into
the United States, except through the Department of Agriculture, has been forbidden.
There is still a great possibility of the spread of its enemies from outside into the
islands. Some very important cane insects also attack corn. The sugar cane is host
to a multitude of insects which feed on its foliage, suck its juices, or bore in its stems or
roots. Many of these insects are not very likely to be imported, but in view of such a
possibility are briefly mentioned.

Ereunetis flavistrlata Walsmgham.
(Sugar-Cane Bud Moth. Tineidse; Lepidoptera.)
Hosts: Sugar cane, palms, banana, pineapple, Pandanus.
Injury: While this species mainly lives in the dead tissues of the above food plants,
it breeds in cane stalks among the dry leaves, but often eats out the eyes or buds,
thus destroying the propagating value of the cane. It may easily be transported in
seed cane.
Description and biology: A small moth, measuring 14 mm. in wing expanse, head
and thorax yellowish white, forewings yellowish white, with indistinct yellow streaks,
hind wings shining pale golden yellow, becoming white at apex. Pupa 5 to 6 mm.
long, pale yellowish brown. Larva 12 to 15 mm. long, whitish, head reddish brown,
hairs on darker tubercles. The larva usually feeds in the dried leaf sheaths, but
sometimes attacks the rind, giving entrance to fungi, and does the greatest damage
by eating out the eyes.
Distribution: Hawaii.

SWEET POTATO.
{Ipomnea batatas Poir. Family Convolvulacese.)
The sweet potato ia now grown in many parts of the world, and, while not often
shipped into the United States because of our own bountiful crops, there is always
likelihood of danger in shipment of tubers for propagation purposes. The only
enemies of the vine which are dangerous are those which attack the tubers.

TOBACCO.
(Nicotiana tabacum Linnaeus. Family Solanacese.)
Tobacco is grown in many parts of the world and is a very important article of
commerce in various forms. Commercial importation^ generally consist of manufac-
tured products, loose leaf, stem, and seed. The greatest dangers lie in the manu-
factured products and loose-leaf tobacco. There are at present no quarantine re-
strictions on tobacco. The tobacco plant has many very important enemies in for-
eign countries, which are not extremely likely to enter the country in connection
with tobacco shipments, but which should be guarded against. Many of these
important insects are listed to assist in the work of identification.

Injury: Very injurious as a stem borer. Stems having swellings should be destroyed .
Desa-iption and biology: Adult moth small and brown with narrow fringed wings.
Pupa stage is spent in stem. Larva, caterpillar bores into the leaf stem and bores
downward in the stalk, causing a swelling to appear in two cr three weeks. In cold
weather this stage lasts 6 to 10 weeks. Eggs deposited singly upon leaves, stems, and
stalks, usually upon the lower side of leaves or stems. In cold weather this stage
lasts 2 or 3 weeks. Warm weather reduces the development from about a third to a
half. (See plate xlvii.)

WATERCRESS.
{Roripa nasturtium.)
A hardy market crop grown in moist soil, ditches, and water courses.
AN IMPORTANT WATERCRESS INSECT.
Limnophilus fiavicornis Fabricius.
(Watercress Caddis Worm. Limnophilidae; Trichoptera).
Hosts: Water cress, Lemna.
Injury: The larvae feed on the leaves.
Biology: The larvae are concealed in cases and live under water. The eggs are laid
in gelatinous masses and are sometimes retained for a while at the extremity of the
female's body, but are finally attached to some aquatic plant.
Distribution: England.

WHEAT; EMMER; SPELT.
{Triticum sativum Lam. and Triticum spp. Family Graminese.)
Wheat is grown in many parts of the world and is a standard article of commerce.
The principal manner in which its insect enemies may be transported is in shipments
of the grain, although the occasional use of straw in packing would be liable to intro-
duce stem-infesting insects. The greater part of the world's wheat crop is grown in
Europe. For full treatment of its insect pests see Grains and grasses.
