Abstract
The following 20 species were recorded as egg predators of the velvetbean caterpillar, Anticarsia gemmatalis Hübner, in Florida soybeans: Orthoptera, Pictonemobius ambitiosus (Scudder); Dermaptera, Labidura riparia (Pallas), Doru taeniatum ,. (Dohrn); Hemiptera, Orius insidiosus (Say), Nabis deceptivus Harris, Nabis capsiformis Germar, Nabis roseipennis Reuter, Pachybrachius bilobatus (Say), Spanogonicus albofasciatus (Reuter), Halticus bractatus (Say); Coleoptera, undetermined coccinellid larva; Neuroptera Chrysopa rufilabris Burmeister, Chrysopa sp., Formicidae, Pheidole dentata Mayr, Conomyrma flavopecta (M. R. Smith), Solenopsis geminata (Fabr.), Solenopsis invicta Buren, Cardiocondyla nuda minutior Forel, Monomorium viridum Brown; Arachnida, Chiracanthium inclusum (Hentz). Egg predators were identified during continuous diurnal observation of eggs placed in the field and by recovering radioactive predators after placing 32 P labeled eggs in the field. Ants and earwigs were recorded as egg predators most frequently during continuous observations. Nabids, chrysopids, and spiders were recorded as egg predators most frequently while using the radioactive tracer. The mean rate of predation on the A. gemmatalis eggs placed in the field for 24 h was 26%. Twelve Species of predators were observed attacking 1st instars of A. gemmatalis .
