Recently, Asian gypsy moth, Lymantria dispar (L.), infestations have been found in Oregon, Washington, and British Colombia. In at least 1 case, circumstantial evidence suggests that the introduction occurred through airborne dispersal of neonates fr

The moth Lymantria mathura Moore is a polyphagous defoliator of forest and fruit trees in the Russian Far East, Japan, India, and China, and it would cause serious economic consequences if established in North America. To project the host range of th

North American gypsy moths disperse as newly hatched larvae on wind currents in a behavior called ballooning. Because ballooning occurs before neonates begin to feed, resources used in dispersal are limited to those carried over from the egg. We show

Arylphorin (Ap) was isolated and partially characterized from larval serum of the gypsy moth, Lymantria dispar (Lepidoptera: Lymantriidae). Non-denaturing and SDS-polyacrylamide gel electrophoresis suggest a 440,000 Da hexamer composed of nonidentica

Tsetse flies (Diptera: Glossinidae:Glossina) mature their offspring in utero, giving birth to mature larvae that burrow into soil and pupariate. During the hot dry seasons, puparia of some species of tsetse are aggregated in areas of deep shade in de

Aspects of development and host preference of the pupal parasitoid Brachymeria intermedia (Nees) were examined in 3 hosts: the gypsy moth, Lymantria dispar L., the greater wax moth, Galleria mellonella L., and the spruce budworm, Choristoneura fumife

Just before the 1973 mating season of Porthetria dispar (L.), a microencapsulated formulation of disparlure, the synthetic sex pheromone of the insect, was applied at the rate of 5 g disparlure/ha to a 60-km2 forested area in Massachusetts that was n

Females of the parasitoid Brachymeria intermedia (Nees) were studied in the laboratory for their response to various physical environmental factors. They preferred low humidities and temperatures between 26 and 29°C in gradients. Most activity was o
