Aspects of Biosteres arisanus (Sonan) (= Opius oophilus Fullaway) (Hymenoptera: Braconidae) development on the oriental fruit fly, Bactrocera (= Dacus) dorsalis (Hendel), were investigated to facilitate mass production in the insectary.

We investigated the potential impact of the imported biological control agent Fopius ceratitivorus Wharton, on the non-target beneficial tephritid, Eutreta xanthochaeta on the lantana weed, Lantana camara. In a no-choice test, where the wasp was offered nothing but infested lantana weed, and in a choice test, where the wasp was offered both the non-target fly and its normal host, Ceratitis capi...
