Abstract
Biotic control agents which feed on the southern chinch bug, Blissus insularis Barber, in Florida were investigated from 1971–77. A scelionid egg parasite, Eumicrosoma benefica Gahan, was the only parasite found. Predatory bugs included: 2 lygaeids, Geocoris uliginiosus (Say) and G. bullatus Say; a nabid, Pagasa pallipes Stal.; 2 anthocorids, Xylocoris vicarius (Reuter) and Lasiochilus pallidulus Reuter; and a reduviid, Sinea sp. Other predators included a dermapteran, Labidura riparia Pallas, several ant species, primarily Solenopsis geminata (F.), and a spider, Lycosa sp. A fungus, Beauveria bassiana (Balsomo) Vuillemin, also attacked B. insularis. The biotic control agents that appeared to regulate populations of the southern chinch bug were: E. benefica, G. uliginosus, X. vicarius, and L. riparia.Keywords
