FRUIT FLY PARASITOID WASP FACTSDescription
Biosteres arisanus is a small Braconid parasitoid wasp that lays its eggs in oriental fruit fly eggs. The adult wasp is reddish brown with long antennae, black eyes, and transparent veined wings. Females have an ovipositor which they use for depositing their eggs inside the host eggs. Their host, tephritid fruit flies are a pest of many types of fruit and vegetables. Biosteres arisanus has been used as a biological pest control agent to reduce numbers of the pest fruit fly. This wasp is also known as Fopius arisanus.

Adult wasps feed on nectar. Wasp larvae feed on fruit fly larvae
Biosteres arisanus lays its eggs in fruit fly eggs, or newly hatches fruit fly larvae. The wasp eggs hatch into larvae which feed on the fruit fly larvae. The wasp larvae pupate and emerge as adult wasps.
This wasp is originally from south east Asia, but has been introduced to Hawaii and continental North America.
