Susceptibility of lady beetles (Coleoptera: Coccinellidae) to entomopathogenic nematodes.
We investigated differential susceptibility of lady beetles to entomopathogenic nematodes, for two reasons: (1) to estimate potential nontarget effects on natural lady beetle populations, (2) to compare the susceptibility of exotic versus native lady beetle species. We hypothesize that successful establishment of some exotically introduced arthropods may be due, in part, to a lower susceptibili...
متن کاملSublethal effects of insecticide seed treatments on two nearctic lady beetles (Coleoptera: Coccinellidae).
Predatory insects often feed on plants or use plant products to supplement their diet, creating a potential route of exposure to systemic insecticides used as seed treatments. This study examined whether chlorantraniliprole or thiamethoxam might negatively impact Coleomegilla maculata and Hippodamia convergens when the beetles consumed the extrafloral nectar of sunflowers grown from treated see...
متن کاملPredation 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 کاملchecklist and distribution of lady beetles (coleoptera: coccinellidae) in iran
this paper is an attempt to fill all of previous literature of coccinellidae records and species distribution in different provinces of iran. distribution was extracted for each species from literatures. there are 6 subfamilies, 16 tribes, 32 genus and 117 species in iran. the largest subfamily, tribe and genus in iran were scymninae, scymnini and scymnus, respectively. the most distribution wa...
متن کاملLarval life history responses to food deprivation in three species of predatory lady beetles (Coleoptera: Coccinellidae).
We studied life history responses of larvae of three coccinellid species, Coleomegilla maculata (DeGeer), Hippodamia convergens Guerin-Meneville, and Harmonia axyridis (Pallas), when deprived of food for different periods of time during the fourth stadium. The coccinellid species did not differ in starvation resistance when larvae were starved throughout the stadium; however, for larvae fed onl...
