Entomology Lab Practical questions with verified
answers
Acrididae Ans✓✓✓ short-horned grasshoppers, orthoptera, family of
agricultural importance as pests; short antenna, pronotum only covers
thorax; generalist feeders that eat plant foliage and particularly like
grasses; damaging as nymphs and adults; defoliators
Aleyrodidae Ans✓✓✓ whiteflies; in order Homoptera; pest of
agricultural importance; damage vegetable crops and often are
greenhouse pest; damaging as nymphs and adults; feed on undersides
of plant leaves, creating mottled or stippled appearance, transmitting
viruses, and leaving sooty mold from honeydew
Anthomyiidae Ans✓✓✓ root maggot flies; in order Diptera; family of
agricultural importance as pests; damage field and vegetable crops;
damaging as larvae; feed on roots, stems, and newly planted seeds
Aphidae Ans✓✓✓ Aphids; Homoptera; have cornicles; many
generations per year, produce honeydew (sooty mold)
Aphididae Ans✓✓✓ Aphids; Homoptera; family of agricultural
importance as pests; damage several vegetable crops, often
greenhouse pest; damaging as nymphs and adults; feed on undersides
of plant leaves, creating mottled or stippled appearance, transmitting
viruses, and leaving sooty mold from honeydew
,Apidae Ans✓✓✓ family in Hymenoptera; honey bees, bumble bees,
carpenter bees; vermiform and exarate; robust, hairy, black and yellow
adults; social and live in colonies
biting insects (medical importance) Ans✓✓✓ Arthropods that can
pierce human skin; mouthparts adapted for piercing, cutting, or
burrowing(some are ectoparasites); often hematophagous (feed on
host's blood); salivary enzymes and other compounds (including
anticoagulants, anesthetics, and vasodilators) may be injected, often
causing a localized reaction or even anaphylactic shock; insects from
Diptera, Hemiptera, Thysanoptera, Pthiraptera, Siphonaptera, and
spiders, mites, and ticks from Class Arachnida
borers Ans✓✓✓ Several species of insects and larvae that tunnel into
timber; mainly Coleoptera, but also Lepidoptera (Sessidae--clearwing
moths, larvae bore into trees) and Hymenoptera;
Buprestidae Ans✓✓✓ metallic wood-boring beetles; flatheaded
borers; Coleoptera; pest of forest importance; can feed in sapwood and
heartwood; brown, sawdust-like boring frass under bark
butterflies Ans✓✓✓ group of Lepidoptera; diurnal, brightly colored,
wings rest together upright, straight and clubbed antenna, thin body,
chrysalis
, Carabidae Ans✓✓✓ ground beetles; Coleoptera; carabiform larvae,
exarate, cursorial legs, dark color, lines along elytra
Cecidomyiidae Ans✓✓✓ gall midges; in order Diptera; insects of
agricultural importance as pests; damage grasses/grains, field crops,
and vegetable crops; damaging as larvae; feed from inside of plant,
causing galls that stunt growth
Cerambycidae (Ag. and forest importance) Ans✓✓✓ long horned
beetles (round-headed borers); pest of Ag importance; Coleoptera;
damage field crops as larvae and sometimes adult; larvae burrow into
stem causing girdling and lodging; also forest pests that can feed under
bark, leaving white, splinter-like frass under bark by boring
Cerambycidae Ans✓✓✓ long-horned beetles; Coleoptera; vermiform
(round-headed borer); exarate; long antennae
Ceratopogonidae Ans✓✓✓ no-see-ums (biting midges)
Cercopidae (Ag. importance) Ans✓✓✓ spittlebugs; Homoptera; family
of agricultural importance as pests; damage grain and field crops as
nymphs and adults; feed by sucking plant tissue, creating mottled
appearance or deformed leaves, virus transmission, sooty mold from
honeydew, large populations can reduce yield
