| 摘要: |
| 用菊酯类农药与低毒的有机磷农药混配对抗性桃蚜进行了毒力测定,筛选出了三个具有明显增效作用的混配组合,并进行了防治桃蚜的田间试验、进一步证实了对抗性桃蚜具有良好的防治效果和增效作用。本文还对有关杀虫剂混配组合的应用价值和经济效益进行了初步探讨。 |

| Abstract: |
| Synergistic interactions between pyrethroids and low toxic organophos- phates were examined using the insecticide-resistant strain of the green pe- ach aphid.Nine combinations of three pyrethroids with common organopho sphates show synergistic activity,although the degrees of the synergism are varied.The mixtures of fenvalerate with dimethoate(1:20)or Omethoate (1:10)and decamethrin with phoxim(1:100)exhabit remarbable synergism, of which the cotoxicity coefficient(CTC)are 425,467 and 410 respec- tively.
