Host Range Testing of Telenomus Remus (Hymenoptera: Scelionidae)
Abstract
Eggs of 39 species of Lepidoptera were tested as possible hosts of Telenomus remus Nixon, a scelionid egg parasite. Spodoptera frugiperda (J. E. Smith) and S. latifascia Walker eggs were used for rearing T. remus and as checks in the host range testing. Of 7 Arctiidae, 1 Ctenuchidae, 5 Geometridae, 1 Mimallonidae, 21 Noctuidae, 2 Notodontidae, and 2 Pyralidae species tested, 11 species of Noctuidae and 1 Pyralidae were parasitized by T. remus. Eggs of 5 Spodoptera spp., 2 Elaphria spp., Heliothis zea (Boddie), and Feltia subterranea (F.) had high emergence rates of T. remus. Eggs of Arzama densa Walker (Noctuidae), and Acigona influsella Hamps (Pyralidae), potential biocontrol agents of aquatic weeds, were not parasitized by T. remus.Downloads
