摘　　要：在室内利用4种赤眼蜂共28个品系对二化螟卵做了寄生率和产卵量试验,选出松毛虫赤眼蜂S-AC品系、螟黄赤眼蜂M-TC品系和稻螟赤眼蜂D-JN品系寄生效果较好。通过田间释放单品系和混合品系得出:稻螟赤眼蜂效果优于螟黄赤眼蜂,螟黄赤眼蜂效果优于松毛虫赤眼蜂,释放混合品系控制二化螟的效果均优于单独释放松毛虫赤眼蜂和单独释放螟黄赤眼蜂,混合品系释放的平均防治效果75%左右,具有广阔的应用前景。A total of 28 strains of four Trichogramma species were used to test the parasitic rate and eggs laying with the eggs of Chilo suppressalis in the laboratory. The results showed that the parasitic effect of S-AC strain of T. dendrolimi, M-TC strain of T. chilonis and D-JN strain of T. japonicum were better. The control efficacy were obtained through the release of single and mixed strains in the field. The effect of T. japonicum was better than that of T. chilonis, and T. chilonis was superior to T. dendrolimi. The effect of releasing mixed strains to control Chilo suppressalis was better than that of T. dendrolimi and T. chilonis alone. The average control effect of the release of the mixed strain was about 75%, which has a wide application prospect.
