| 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.
