There were 12 species of scale insects and 13 species of natural enemies, including 8 parasitic species, 5 predatory species, 10 species of cerambycidae, 1 species of sexual predators, 4 species of leaf-roll insects, 11 species of natural enemies, including 2 species of parasitism, 9 species of predation, 4 species of food worms and 13 species of natural enemies, including 6 species of parasitism and 7 species of predatory species. 26 kinds of natural enemies, including 26 kinds of natural enemies, including 1 species of parasitism and 25 species of predation.
