Gypsy moth, Lymantria dispar L., populations in six northern Virginia plots were aerially treated with the nucleopolyhedrosis virus product, Gypchek. Two applications of an aqueous Orzan LS-Pro Mo-Rhoplex B60A tank mix, each at 18.7 liters and 1.25 × 1012 polyhedral inclusion bodies per ha, reduced larvae by more than 92% and egg masses by more than 94% in all but one of the treated plots. Defoliation averaged 22% in Gypchek-treated plots compared to 67% in control plots.

Nucleopolyhedrosis Virus

In central Serbia, a total of 88 species which are natural enemies of the gypsy moth, i.e. 23 predators, 49 parasitoid insects and 10 saprophagous insects, and 6 pathogens, has been reported. The most abundant of them are the insects which attack the gypsy moth in the larval instar (41 species). Regarding the number of the species, the representatives of the Hymenoptera (14 species from Ichneumonidae family and 11 species from Braconidae family) and Diptera orders (12 species from Tachinidae family and 8 species from Sarcophagidae family) are most frequent. Regarding the predators of the gypsy moth, Carabidae family, from Coleoptera order, is most frequent. In addition, at some sites Lymantria dispar nucleopolyhedrosis virus and Entomophaga maimaiga had the dominant role in the reduction of the gypsy moth density.

First Time

AbstractCarabid beetles were collected using pitfall traps and tree bands in forest stands in southwestern Pennsylvania subjected to defoliation by gypsy moth for the first time. Some of the stands were treated aerially with Bacillus thuringiensis Berliner (B.t.). The guts of all carabids collected were tested for the presence of gypsy moth proteins using the ELISA technique. Twenty-seven of the 33 species (82%) collected from pitfall traps, and four of the seven species (57%) collected under tree bands, tested positive. Of the 1142 individuals from pitfall traps and 73 individuals from tree bands, the percentages positive were 45 and 38%, respectively. Calosoma frigidum Kirby had the highest percentage positive (78%) of any species. Statistically significant differences in percentages positive between B.t.-treated and untreated plots were found only for Pterostichus mutus Say and P. coracinus Newm., and when all species were combined. The presence of nucleopolyhedrosis virus in the gypsy moth population was unanticipated and may have influenced these results through increased feeding on carrion.
