Phenotypic plasticity in sexual communication signal of a noctuid moth.
Variability within sex pheromone signalling systems is generally believed to be low because of strong stabilizing selection; yet the noctuid moth Heliothis subflexa (Hs) shows significant intraspecific variation. One possible explanation is that females may alter their sex pheromone blend depending on prevailing olfactory cues in the habitat, which we termed the 'experience hypothesis'. This co...
متن کاملEntomopathogenic Hyphomycetes Associated with Gypsy Moth Larvae
Gypsy moth, Lymantria dispar, populations were sampled in four eastern North American states during 1991 and 1992 to evaluate levels of hyphomycete infection in association with releases of the Asian gypsy moth pathogen Entomophaga maimaiga. Paecilomyces farinosus was the most abundant hyphomycete species, occurring at the majority of sites, although levels of infection averaged only 4.6% (1991...
متن کاملThe management of diamondback moth and other crucifer pests
The timing of pest insect attacks can vary greatly from region to region and from year to year. A simulation method, based on rates of insect development, has been developed for forecasting the timing of insect attacks on cruciferous crops. The method is based on using a fixed number of individuals from one generation to the next and simulates the timing of events in the life cycle of the pests...
متن کاملTree Mortality in Mixed Pine-Hardwood Stands Defoliated by the European Gypsy Moth (Lymantria dispar L.)
Defoliation by the European gypsy moth (Lymantria dispar L.) and subsequent tree mortality have been well documented in the northeastern United States. In this study we evaluate tree mortality after initial defoliation in mixed pine-hardwood stands in the southeastern United States as the range of European gypsy moth expands. In 1993, 46 mature pine-oak and pine-sweetgum stands were selected on...
متن کاملThe management of diamondback moth and other crucifer pests
Investigations of host plant-pest interactions have rarely used plant material in which the phenotype could be linked directly to a known genotype. However, in recent years, Arabidopsis thaliana has been intensively studied by molecular biologists and, as a result, there are a large number of genetically characterised A. thaliana mutants available to the scientific community. Our preliminary la...
