Predation by adult and larval lady beetles (Coleoptera: Coccinellidae) on initial contact with lady beetle eggs.
Naïve adults and larvae of the native lady beetles Coleomegilla maculata (DeGeer), Cycloneda munda (Say), Hippodamia convergens Guérin-Méneville, Olla v-nigrum (Mulsant), and the exotic lady beetle Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae) were tested for their initial response to eggs of these five lady beetle species and for egg consumption on first contact and after 3 h. Additio...
متن کاملAntifeedant and insecticidal activities of selected plant extracts against Epilachna beetle, Henosepilachna vigintioctopunctata (Coleoptera: Coccinellidae)
Six different indigenous plants were screened for antifeedant and insecticidal activity against fourth instar larvae of Epilachna beetle, Henosepilachna vigintioctopunctata, which is a severe pest on brinjal. Among the plants screened, Achyranthes aspera showed higher activity against the selected pest. Ethyl acetate extracts of A. aspera showed higher antifeedant index and insecticidal activit...
متن کاملSusceptibility of a native and an exotic lady beetle (Coleoptera: Coccinellidae) to Beauveria bassiana.
The exotic multicolored Asian lady beetle, Harmonia axyridis, became established and recently spread across much of North America and southern Canada. In a habitat now used by both the invading H. axyridis and a native lady beetle, Olla v-nigrum, we discovered that the native lady beetle was commonly infected by Beauveria bassiana; whereas, the exotic H. axyridis, was not. Laboratory assays rev...
متن کاملInteractions of native and non-native lady beetle species (Coleoptera: Coccinellidae) with aphid-tending ants in laboratory arenas.
Interactions between lady beetles and the European fire ant (Myrmica rubra L.) tending potato aphids [Macrosiphum euphorbiae (Thomas)] were compared in the laboratory. Lady beetle species native to North America (Coccinella trifasciata perplexa Mulsant, Coleomegilla maculata lengi Timberlake, Hippodamia convergens Guérin-Méneville) and non-native species of Palearctic origin [Coccinella septemp...
متن کاملSterol limitation in a pollen-fed omnivorous lady beetle (Coleoptera: Coccinellidae).
Nutritional constraints of non-prey foods for entomophagous arthropods are seldom investigated, yet are crucial to understanding their nutritional ecology and function within natural and managed environments. We investigated whether pollen from five maize hybrids was of variable quality for the lady beetle, Coleomegilla maculata, whether suitability of these pollens was related with their stero...
