Numerical Change

The host species consumed by larval gypsy moths have significant influences on their development. Feeding on red maple, red oak, synthetic food, and a diet of both oak and maple results in differences in mean frass production, pupal weights, and development times. Larvae feeding on the preferred food type, oak, consumed more food and produced heavier pupae than those that fed on nonpreferred maple. Development in oak-fed female larvae is significantly faster than in maple-fed female larvae. A relatively consistent proportion of extra-instar larvae of both sexes were found regardless of the food they feed upon. The implications of food type on numerical change in gypsy moth populations is discussed.

AbstractThe impact of predation by Calosoma sycophanta L. on an increasing prey population was assessed by recapturing marked adult beetles, periodically observing tagged gypsy moth pupae, and examining gypsy moth pupal remains in different microhabitats. Adult beetles dispersed in random directions but many tended to remain near the trap at which they were originally caught, suggesting a low dispersal potential. About 75% of the adult beetles present in the plot on one day were still present the next day. Capture–recapture estimates suggested that there were at most about 250 male beetles and half as many females/ha in the plot. Calosoma larvae destroyed 70% of tagged gypsy moth pupae under burlap bands on tree trunks near ground level, which was much more than any other mortality factor. Although this percentage was the same when mortality was assessed by looking at pupal remains within 5 m of the ground on tree trunks, pupae higher in trees and on leaves were not attacked as frequently. On average, about 40% of the pupae present in the entire study area were destroyed by Calosoma larvae. Each female beetle in the site would have had to produce about 30 progeny to have this effect. These data suggest that a relatively low number of adult beetles can have a substantial impact on gypsy moth populations.
