Parasitoids recovered from European corn borer, Ostrinia nubilalis Hubner, (Lepidoptera : Pyralidae) larvae in Nebraska
Journal of the Kansas Entomological Society 70 (4), 365-367
Abstract: Information about the current status of parasitoids attacking European corn borer, Ostrinia nubilalis (Hübner), larvae is lacking in Nebraska. This study was conducted at multiple sites in 5 counties during 1995 and 1996 to determine the presence and prevalence of European corn borer parasitoids in Eastern Nebraska. The braconid, Macrocentrus grandii Goidanich, was recovered from 8.9 and 10.2% of collected 5th instar European corn borer larvae during 1995 and 1996, respectively. Recovery of this parasitoid had not been previously reported in Nebraska. Meanwhile, the ichneumonid, Eriborus terebrans (Gravenhorst), was recovered from 7.6 and 7.5% of collected larvae during the same period. A small number of the native tachinid parasitoid, Lixophaga spp., were recovered in three collections. Combined parasitoid recovery rates for all species was 16.6 and 17.7% during 1995 and 1996.
