From June to September in 1980, Wuhan, Hubei Province, Wuhan and other seven counties (cities) representative of different types of cotton fields were investigated in all generations of cotton bollworm eggs parasitic natural enemies, a total of 21 surveys, Out of a total of 177 bees (♀ 98, ♂ 79), the parasitism rate was 1.69%.
