According to another four-year life table data, the average survival of painting turned punctatus C} curve shows that the survival curve of the first generation of larvae belonging to Price (1975) the division of A (Figure II) indicating that the first generation of caterpillars orange worm God garlic Square three age when mortality has reached the end of 0O about. Insect attacks on filial piety that is easy and low resistance power. T 'three> days knocking species and their effects, lack of life tables of four years} of Lattice caterpillar natural enemies recorded a total of 42 species,[link widoczny dla zalogowanych], of which l6 species of parasitoids, prey species of days dare to lie down. According to the forest survey, natural enemies are parasitic eggs pine 3,[link widoczny dla zalogowanych], the average parasitism rate was 7.0l%, mainly parasitoids difficult for the red bee. Larvae of parasitic natural enemies of 8 species, the average parasitism rate was 23.1%,[link widoczny dla zalogowanych], mainly small parasitic natural enemies of red head flies and parasitic wasps. Chi on the parasitoids have black spots pine and wild silkworm tumor ichneumonids Ichneumonidae melanoma. Predators in the population of orange caterpillars are more significant inhibition of the Chinese broad shoulders and beetle, the average prey on the larvae was 24.8, followed by the great tit and other birds. Clear from the parasitic natural enemies of natural enemies and prey population dynamics in the pine has an important role. This and the preceding M (si> values consistent with the results. Lan.
