A theoretical analysis of the feasibility of controlling tick populations (Ixodidae) by the release of reared Ixodiphagus parasitoids in tick ecosystems yielded promising results. The analysis suggested that if reasonable progress could be made in ma

The overwintered population density of the tobacco budworm, Heliothis virescens (F.), was estimated during 1981–83 for an area 146.4 km2 in the central delta of Mississippi. Pheromone-baited cone traps were used to trap wild and released tobacco bu

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

Use of disparlure to disrupt mating of low-density populations of gypsy moths, Porthetria dispar (L.), was tested in central Massachusetts in 1974. In one area with a naturally low population, disparlure in slow-release microencapsulated form was app

This paper is concerned with the dynamics and host plant relationships of Heliothis populations as they develop seasonally in the Mississippi Delta region, and the implications they have on strategies for Heliothis management. It will also consider t

A technique for mass-rearing Trichogramma spp. on Heliothis zea (Boddie) eggs is described. A comparison was made of the fecundity and longevity of Trichogramma reared for 3 generations on Anagasta (= Ephestia ) kuehniella (Zeller) and Sitotroga cere
