Parasitic wasps and flies
Parasitic wasps and flies are important natural enemies
of stink bugs or other true bugs. Wasps attack the eggs and
parasitic flies attack nymphs and adults.
Insect parasitic wasps, or parasitoids, are smaller than their host and develop inside the host's body.
The immature stage of the parasite feeds on the host and it kills only one host during its development.
The parasitic wasp, Trissolcus basalis, has been imported from Europe and released in several locations
throughout the state.
The most common parasitic flies are in the family Tachinidae. Adult tachinids often resemble houseflies,
and their larvae are maggots that feed inside the host they parasitize.
