采用点滴法测定了橘小实蝇广州种群对敌百虫、高效氯氰菊酯、阿维菌素的抗性。结果表明:7月橘小实蝇对敌百虫产生了低水平抗性,抗性倍数为3.57倍,抗性个体频率为74.00%;7—11月橘小实蝇对高效氯氰菊酯均产生了低水平抗性,10月抗性倍数和抗性个体频率较高,分别为6.23倍和44.00%;橘小实蝇对阿维菌素尚处于敏感阶段,各月份的抗性倍数、抗性个体频率之间无显著差异。
The resistance to trichlorfon, beta-cypermethrin and abamectin in Guangzhou population of Tricholoma giganteum was determined by the method of spotting. The results showed that in July, Trichosanthes trichocarpa produced a low level of resistance to trichlorfon, with a resistance multiple of 3.57 times and a resistance frequency of 74.00%. In July-November, Trichosanthes flies produced low levels of beta-cypermethrin Horizontal resistance and the frequency of multiple resistance and resistant individuals in October were 6.23 times and 44.00%, respectively. The sensitivity of Abamectin to the fruit fly was still in the sensitive stage. The resistance multiple of each month and the frequency of resistant individuals No significant difference between.
