GFP lights up toxin around wasp eggs

Caption

Two early-stage wasp larvae removed from a fruit fly, Drosophila melanogaster, that had been parasitized by the wasp Leptopilina boulardi. The fly expressed the fusionB gene that UC Berkeley researchers had inserted, producing an enzyme toxic to the wasp. The toxin is tagged with a green fluorescent protein, showing that it latches onto the larvae before killing it.
