4. Derived from: Legner, E. F. 1962. Some biotic control factors affecting the eye-spotted bud moth, and red-banded and fruit-tree leaf rollers in Wisconsin. Entomol. Soc. Amer. North Cent. Br. Proc. 17: 115-117.

Summary

Parasites were reared from collected larvae and pupae of the three species in 1959 and 1960. Parasitism of 70-collected eye-spotted bud moth larvae in 1959 was zero, but 0.3 percent of 1032 larvae collected in 1960 showed parasitism. Of 169 collected pupae in 1959, 2.9 percent were parasitized; while 8.8 percent of 442 collected pupae in 1960 showed parasitism. Parasitism of the red-banded leaf roller was zero in 1959, but 16.7 percent of 33 first-generation larvae and pupae collected in 1960 were parasitized. Parasitism of fruit-tree leaf roller pupae was 21.4 percent in 1959 (14 collected pupae) and 31.4 percent in 1960 (37 collected pupae).
