Class Insecta: Order Hymenoptera WASPS Flashcards
wasps
-200,000 species
warning coloration (aposomatic)
wasps, hornets, yellowjackets
behavior
parasitic wasps or parasitoids (necrotroph) lay their eggs in inert stages of their host (egg or pupa) or sometimes paralyze their prey by injecting it with venom through their ovipositor and then insert one or more eggs into the host or deposit them upon the host externally; the hose remains alive until the parasitoid larvae are mature, usually dying either when the parasitoids pupate or when they emerge as adults
galls
tumorlike growth (branches, trunk, roots, leaves) produced by the plant (variety of shapes and colors) in response to an invading organism- insect (flies, midges, fruit flies, moths, wasps): used as a nursery site for their offspring -oak apples
micro-ecosystem
a) inducer
b) parasitoid
c) hyperparasitoid
d) inquiline
inducer
gall forms in response to insect
parasitoid
insect lays eggs in gall and larvae kill the hose (inducer insect)
Hyperparasitoid
insect that is a parasite of the parasitoid
inquiline
insect that lives inside the gall and feeds on its tissue: cohabits with the inducer insect
nests
the type of nests produced by wasps can depend on the species and location, many social wasps produce paper pulp nests on trees, in attics, holes in the ground or other such sheltered areas with access to the outdoors, unlike honey bees, wasps have no wax producing glands and many create paper-like substance primarily from wood-pulp, that is softened by chewing and mixed with saliva and then used to make combs with cells for brood rearing
