| 摘 要： | 研究表明,螟黄赤眼蜂对新疆南部棉区棉铃虫的控制作用优于松毛虫赤眼蜂;田间放蜂量6×104～8×104头/667m2、放蜂点为3～6个/667 m2,螟黄赤眼蜂最高寄生率达51.49;,累计寄生率为18.67;～44.02;,平均寄生率30.36;,棉铃虫虫口减退率25.3;～64.2;,蕾铃被害减退率46.8;～76.8;,赤眼蜂对新疆棉田棉铃虫具有明显的控制作用;同时,持续放蜂田天敌数量明显高于化防田,表明持续放蜂生态效应显著.

Study on Using Mass-release Trichogrmma Chilonis to Control Helicoverpa Armigera in Cotton Field in Xinjiang |
| |
| Abstract: | In the experiment, T.Chilonis to Helicoverpa armigera and Trichogramma dendrolimi Matsumura were separately used to control the seeond generation of Helicoverpa armigera in cotton field in the south of Xinjiang. The results showed that the former had better control effect than the latter. The control effect of T. chilonis to Helicoverpa armigera was examinated, and the highest parasite rate could reach 51.4%, and the average parasite rate is 30.36%. the results show that T. chilonis plays certain control role to target, and sustainable mass-releasing T. chilonis in cotton field has significant ecological effect. |
