Abstract:
... Populations of Callirhytis cornigera (Osten Sacken) and its associated community of natural enemies and inquilines were monitored on pin oak, Quercus palustris Muenchhausen, in Lexington, KY, from 1997 to 1999. The gall wasp has alternating agamic and sexual generations that differ morphologically and develop in multichambered galls on branches and single-chambered galls on leaves, respectively. T ...

All four species were freeze-susceptible. However, there was variation within and among species in overwintering biology that related to their geographic distribution. D. frontalis and southern populations of I. gra ...

Abstract:
... Mass-trapping using semiochemical lures is a potentially useful control measure against bark beetle pests. A serious problem, however, is the inadvertent removal of predators that respond to these baits as kairomones. Ips pini (Say) infests hard pines in the western, Great Lakes, and eastern forests of North America. In Wisconsin, I. pini responds primarily to 50 (+)/50(-) and 75(+)/25(-) blends o ...

We studied the effects of date of hatch, maternal population quality, larval density, air temperature, and host foliage on the dispersal of neonate gypsy moths, Lymantria dispar (L.), under field conditions. Larval dispersal significantly increased with date by nearly fourfold, but neither maternal population quality nor crowding had a significant effect on dispersal activity. Neither variation in ...

Surveys in four agro-ecological zones of Benin, conducted between 1993 and 1997, revealed approximately 20 plant species from 11 plant families hosting the borer, but only 13 host plants enable the borer to develop to the pupal stage. Whereas, a maize crop usually supports one ...

Previous studies have postulated that the quality of resources that female gypsy moths, Lymantria dispar (L), allocate to their eggs may affect the growth, development, and population dynamics of larvae in subsequent generations. To test this hypothesis, we collected eggs from food stressed and unstressed populations and measured critical life history parameters (e.g., dispersal, growth rate, mort ...

Abstract:
... The browntail moth, Euproctis chrysorrhoea (L.), is periodically a major urban pest in the southern United Kingdom. High populations cause severe defoliation of a range of host plants, often in urban areas; and urticating hairs of larvae are highly irritating to humans. Control of outbreak populations is therefore desired. As an alternative to chemical insecticide sprays and labor intensive nest r ...
