A new distribution and host record for Gonatocerus triguttatus in Florida, with notes on Acmopolynema sema (Hymenoptera: Mymaridae)
Florida Entomologist 85 (4), 654-655
Abstract: A survey of egg parasitoids of proconiine sharp-shooters was conducted in Florida, USA, in August 2001. The mymarid wasp Gonatocerus triguttatus was reared from an egg mass of Oncometopia nigricans laid in a crape myrtle leaf in Apopka, Florida. This discovery is the first known record of G. triguttatus from Florida and also a new host record for this parasitoid species. Another mymarid wasp, Acmopolynema sema, was reared from egg masses of Homalodisca insolita on Johnson grass in Belle Glade, Florida; females of A. sema were then exposed to egg masses of a factitious host for this parasitoid, Homalodisca coagulata, on Euonymus japonica leaves at the UCR quarantine laboratory. A colony of A. sema was lost in the second, all male, generation, after the first generation, which included both sexes, had been obtained successfully on H. coagulata eggs.
