Marked, laboratory-reared gypsy moth, Lymantria dispar L., second instars were released at the base of oak trees in a declining gypsy moth population. By periodically noting the proportion of caterpillars observed that had been released, it was found that little intertree dispersal of second and third instars occurred. Movement within a tree did occur, however. Dispersal of gypsy moth fourth through sixth instars was measured by determining changes in the proportion of marked caterpillars resting under burlap bands placed around the trunks of isolated trees. Results suggest that large larvae disperse little except just prior to pupation. The lack of significant dispersal in all larval stages made it possible to estimate from mark–recapture studies the proportion of larvae that survive from one day to the next. Daily survival rates were 0.6–0.7 for small larvae and ca. 0.8 for large ones.

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.
