本文利用室内培育的、具有一定生理生化差异的4个溴氰菊酯抗性和3个敏感性棉蚜株系,通过大田罩笼试验,用喷雾法测定了溴氰菊酯抗性棉蚜对速灭菊酯、功夫菊酯、甲胺磷、马拉硫磷和呋喃丹的交互抗性,并将结果与点滴测定法进行了比较。结果得出,喷雾法更接近大田施药情况,能更准确地测定出低水平的交互抗性(如甲胺磷)。同时本文还首次建立了描述交互抗性程度的定量指标。 In this paper, four deltamethrin resistant and three susceptible cotton aphid strains with physiological and biochemical differences indoors were used to test deltamethrin resistant cotton aphid Cross-permethrin, cyhalothrin, methamidophos, malathion and carbofuran cross-resistance, and the results were compared with the spotting assay. The results showed that the spray method is more close to field application, can more accurately determine the low level of cross-resistance (such as methamidophron). At the same time, this article also establishes the quantitative index describing the degree of cross-resistance for the first time.
