Subject:
Lymantria dispar; females; insect flight; inheritance (genetics); crossing; heritability; hybrids; wings; flight muscles; geographical variation; dispersal behavior
Abstract:
... A clinal female flight polymorphism exists in the gypsy moth, Lymantria dispar L., where female flight diminishes from east to west across Eurasia. A Russian population where females are capable of sustained ascending flight and a North American population with females incapable of flight were crossed: parentals, reciprocal F1 hybrids, double reciprocal F2 hybrids, and all possible backcrosses to ...

Abstract:
... Female gypsy moths, Lymantria dispar L., from 46 geographic strains were evaluated for flight capability and related traits. Males from 31 of the same strains were evaluated for genetic diversity using two polymorphic cytochrome oxidase I mitochondrial DNA restriction sites, the nuclear FS1 marker, and four microsatellite loci. Females capable of strong directed flight were found in strains that o ...

Abstract:
... In the laboratory, the timing of both preflight and flight behaviors of the Asian strain of female gypsy moths, Lymantria dispar L., was regulated primarily by light intensity. The shortest times to initiation of wing fanning and flight occurred at 0.1 lux, the lowest light intensity evaluated. A gradual decrease in light intensity, compared with an instantaneous decrease, prolonged time to flight ...

Abstract:
... Head capsules of 579 individuals from 28 different populations of gypsy moth, Lymantria dispar (L.), were reliably classified with an analysis of their color spectrum. Based on 26 variables, derived from approximately 17 million color combinations of red, green, and blue, a set of numeric characteristics permitted discrimination between gypsy moth populations from the former Soviet Union, the nort ...

Abstract:
... Feeding habits of Korscheltellus gracilis (Grote) were determined in the laboratory and field in Vermont. Gymnosperm and angiosperm seedlings and one fern were exposed to larvae. Significant reductions in root length or volume occurred in all three taxa. Larvae removed root bark and phloem and often girdled stem bases. Feeding damage was similar to that found in high elevation spruce-fir forests o ...

Abstract:
... In field studies in the Russian Far East, five types of illuminating devices were evaluated for attracting adult gypsy moth, Lymantria dispar (L.), pink gypsy moth, L. mathura Moore and nun moth L. monacha (L.). Our objective was to determine if light from commercial lamps suited to out-of-doors floodlighting could be modified to reduce their attractiveness to moths without a reduction of illumina ...

Abstract:
... In 1987, four gypsy moth, Lymantria dispar, (L.) densities were established in eight 1-ha plots in western Massachusetts, ranging from 50,000 to 1.4 M neonates per hectare. Two tachinid parasitoid species, Compsilura concinnata (Meigen) and Parasetigena silvestris (Robineau-Desvoidy), exhibited spatial density-dependent parasitism and C. concinnata was the majors source of gypsy moth mortality.
