| 摘 要： | 使用赤眼蜂防治大豆食心虫是生物防治重要手段之一,但不同寄主卵繁育的赤眼蜂对大豆食心虫卵选择性不同。针对使用柞蚕卵繁育的赤眼蜂与使用麦蛾卵繁育的赤眼蜂对大豆食心虫的寄生效果进行比较,试验结果存在明显差异。结果表明：使用柞蚕卵繁育的赤眼蜂较使用麦蛾卵繁育的赤眼蜂产卵能力下降10%,飞翔能力差,对大豆食心虫防治效果低于60%。使用麦蛾卵繁育赤眼蜂生存时间延长1～2d,对大豆食心虫防治效果在60%以上,且次代幼虫发育良好,所发育的成虫能有效控制第二年大豆食心虫虫口基数,可以起到良好的防治连锁效果。综合分析认为,使用麦蛾卵繁育赤眼蜂能更有效控制大豆食心虫,且连续防治效果表现明显。

| 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. |
