应用糖醋液诱集鲜食玉米田小地老虎成虫试验

Application of sweet and sour liquid to control the adult of black cutworm(Agrotis ypsilon) in the fresh corn field

为了明确糖醋液对鲜食玉米田小地老虎的防治效果,试验设置了3种不同配比浓度的糖醋液,比较不同处理间诱蛾数量及田间保苗效果。结果表明:糖醋液对鲜食玉米田小地老虎成虫具有较好的诱集作用,不同处理间成虫诱集数量存在显著差异,以处理3(糖:醋:酒:水=3:6:1:10)诱集效果最好,显著高于处理1(糖:醋:酒:水=1:4:1:10)和处理2(糖:醋:酒:水=3:4:1:10)。糖醋液处理的百株虫量、株为害率都显著低于对照田;不同处理间的保苗效果表现较好,但差异不显著,依次为:处理3(83.3%)>处理2(77.1%)>处理1(75.0%)。糖醋液对鲜食玉米田小地老虎有较好的控制作用,具有较好的推广应用前景。

To clarify the control effect of sweet and sour liquid on the black cutworm in fresh corn field,3 kinds of sweet and sour liquid were studied,the trapping effect and seedling protection effect were compared.The results showed that the sweet and sour liquid had better control effect on the black cutworm,there were significant differences in the number of trapping insects between different treatments.Treatment 3(sugar:vinegar:vine:water=3:6:1:10)the attraction effect is the best,significantly higher than treatment 1(sugar:vinegar:wine:water=1:4:1:10)and treatment 2(sugar:vinegar:wine:water=3:4:1:10).In addition,insect density of 100 strains and the damage rate were significantly lower than the control field.There was no significant difference in seedling protection effect between different treatments,the descending order was treatment 3(83.3%)>treatment 2(77.1%)>treatment 1(75.0%).Therefore,the sweet and sour solution has good protective effect on the black cutworm in the fresh com field and is worthy to be widely used.
