Abstract
Using Trichogramma to control the soybean pod borer is one of the important biological control means.Trichogramma bred by different host eggs had different selectivity on soybean pod borer eggs.The parasitism effect of Trichogramma bred by Antheraea pernyi eggs and Gelechiidae egg was compared.The result was significant different.The results showed that egg production capacity of Trichogramma bred by Antheraea pernyi eggs decreased by 10% compared to Trichogramma bred by Gelechiidae eggs,the control effect to soybean pod borer less than 60%.The survival of Trichogramma bred by Gelechiidae eggs could prolong 1~2 days,the control effect to soybean pod borer could more than 60%,moreover,second-generation larvae was well-developed,and the adult could effectively control the second year of the soybean pod borer pest base,could play a good effect to combat chain.Comprehensive analysis believed that Trichogramma bred by Gelechiidae be more effectively to control soybean pod borer,and continuous control performance was significantly.关键词
