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.

AbstractA variety of field sampling procedures were used to estimate population levels of the gypsy moth, Porthetria dispar (L.) (Lepidoptera: Lymantriidae), and the following natural enemies: Apanteles melanoscelus (Ratzeburg) (Hymenoptera: Braconidae), Blepharipa scutellata (Robineau-Desvoidy) (Diptera: Tachinidae), and Calosoma sycophanta (L.) (Coleoptera: Carabidae). Regression analyses indicated, among other things, that gypsy moth egg mass counts were not good indicators of tree defoliation, but that defoliation and number of gypsy moth larvae on branch terminals were correlated. Estimates of adult abundance of A. melanoscelus and B. scutellata were negatively correlated with estimates of numbers of immature parasitoids. Numbers of gypsy moth larvae parasitized by A. melanoscelus were positively correlated with numbers of A. melanoscelus cocoons sampled. Numbers of adult C. sycophanta were not correlated with larval numbers of this insect. It was concluded from these results that the procedures used to estimate numbers of natural enemy adults were not entirely adequate, but may be useful for supplementing other sampling methods.
