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 کاملAdaptive phenotypic plasticity: consensus and controversy.
Phenotypic plasticity is an environmentally based change in the phenotype. Understanding the evolution of adaptive phenotypic plasticity has been hampered by dissenting opinions on the merits of different methods of description, on the underlying genetic mechanisms, and on the way that plasticity is affected by natural selection in a heterogeneous environment. During much of this debate, the au...
متن کاملConservation of digestive enzymes.
The traditional understanding is that an entirely new complement of digestive enzymes is secreted by the pancreas into the small intestines with each meal. This is thought to be necessary because, like food itself, these enzymes are degraded during digestion. In this review we discuss experiments that bring this point of view into question. They suggest that digestive enzymes can be absorbed in...
متن کاملPopulation Dynamics of Gypsy Moth in North America
The gypsy moth, Lymantria dispar, is a major defoliator of deciduous trees throughout the northern hemisphere. Introduced into eastern Massachusetts from Europe in 1868 or 1869, it has gradually spread south and west and will soon occupy most of the hardwood forests in the eastern United States and Canada. The gypsy moth has been the subject of intensive study by scientists throughout the world...
