| Inhoud: |
Epizootics caused by Beauveria bassiana and Nomuraea rileyi have been observed on boll worms and Spodoptera litura in south Indian fields during winter since the last 15 years. During the N. rileyi-induced natural epizootics, some boll worms were found surviving without infection. Whether they represent pathogen-resistant genotypes was investigated. Two insect populations, collected 3 months prior to and during the epizootic were established. Their sensitivity to both the fungi was compared in laboratory bioassays. No significant difference in sensitivity was observed between the two populations. It was concluded that the boll worm population surviving the epizootic was not genotypically resistant. |
