SIMILARITY OF THE HYPERPARASITOID COMMUNITIES ATTACKING 2 STRAINS OF A GYPSY-MOTH (LEPIDOPTERA, LYMANTRIIDAE) PRIMARY PARASITOID, COTESIA-MELANOSCELA (HYMENOPTERA, BRACONIDAE)
Am. Wieber et al., SIMILARITY OF THE HYPERPARASITOID COMMUNITIES ATTACKING 2 STRAINS OF A GYPSY-MOTH (LEPIDOPTERA, LYMANTRIIDAE) PRIMARY PARASITOID, COTESIA-MELANOSCELA (HYMENOPTERA, BRACONIDAE), Annals of the Entomological Society of America, 89(1), 1996, pp. 47-52
Cocoons of die U.S. strain and the Korean strain of the gypsy moth, Ly
mantria dispar (L.), primary parasitoid, Cotesia melanoscela (Ratzebur
g), were placed at 3 sites in Maryland to examine the hyperparasitoid
community that use the cocoons. The Korean str ain produces a larger s
ilk halo surrounding the cocoon that may provide protection against pa
rasitism by individual species in the hyperparasitoid community which
is not available to the U.S. strain. There were differences in species
composition of the hyperparasitoid community among sites, but not bet
ween strains at a single site. There was little or no difference in me
asurements of the hyperparasitoid communities (species richness, perce
ntage of niche use, species diversity and species evenness) attacking
the U.S. and Korean strains. The extended halo associated with the Kor
ean strain cocoons does not appear to offer any additional protection
against parasitism by the hyperparasitoid community present at these s
ites.
