摘要
研究了2种蚜茧蜂对烟蚜的复合控制作用,运用复合防控法(烟蚜茧蜂∶菜蚜茧蜂比例为1∶1)及单一防控法(烟蚜茧蜂)接蜂.结果表明:接蜂30d内复合防控寄生率比单一防控高,最大值为76.44%,烟蚜虫口减退率最大值为90.69%,出蜂量均显著高于单一防控,羽化率最大值为22.89%,烟株各部位僵蚜量、虫口减退率均高于单一防控.接蜂不同天数寄生率、虫口减退率、羽化率的差异均具有统计学意义(p<0.05).蚜茧蜂复合防控烟蚜效果明显优于单一防控.
In this paper,the control effect has been researched on Myzus persicae（Sulzer）by Aphidius gifuensis Ashmead and Diaeretiella rapae M′Intosh by using thecombination control（A.gifuensis∶D.rapae=1∶1）and single control（only A.gifuensis）.It shows that the parasitic rate of compound control is higher than that of the single control,the maximum is 76.44%,the maximum declining rate of insect population ofM.persicae is 90.69% during 30 days of compound control.The number of adults bythe compound control is significantly higher than that in the single control,and the maximum of the emergence rate is 22.89%.The number of mummified aphid and population declining rate by the compound control is higher than that of the single control,and there are significant differences in parasitic rate,declining rate,emergence rate under different days（p〈0.05）.It is obvious that the compound control is better than the single control.
