| 摘 要： | 为比较内吸性杀虫剂不同混配比例对水稻大螟的防治效果,采用水稻茎秆对药剂的内吸性进行水稻大螟的生物测定。结果表明:内吸性强毒力性高的药剂和内吸性弱毒力性差的药剂复配时,前者药剂所占比例越大,混合后效果较好;内吸性强毒力性弱的杀虫剂与内吸性弱毒力性强的杀虫剂复配时,将增强药剂的作用效果。

| Abstract: | The rice stem was treated by different systemic pesticide combination to determinate the biological activity of Sesamia inferens Walker for investigating control effects of different systemic pesticide combination on Sesamia inferens Walker.The results show that the toxicity of mixtures increases with increase of the former proportion when the strong systemic pesticide with higher toxicity mixes with the weak systemic pesticide with lower toxicity,and the mixture of the strong systemic pesticide with lower toxicity mixed with the weak systemic pesticide with higher toxicity can enhance the effect on Sesamia inferens Walker. |
