Trichogramma evanescens Westwood, 1833 is a species of parasitic wasp (Hymenoptera: Trichogrammatidae). Adults are small (barely visible to the naked eye) labeled ‘parasitoids’, which means they deposit their eggs in the eggs of their host species, which is quite varied (can parasitize eggs of several hundred species of moth). The resulting egg hatches and consumes the host internally. Trichogramma, like other hymenopterans, have a complete life cycle with an egg, larva, pupa, and adult stage. Because of their parasitism behavior, broad host range, and ability to be mass-produced in colony, Trichogramma species have been used extensively as a biological control agent (their parasitism suppresses pest populations) in agricultural commodities around the world.
