采用浸叶法测定了噻嗪酮对烟粉虱幼螨的影响。该方法是强大的和可重复的，基线数据计算的实验室菌株和一些现场收集的巴基斯坦，其中没有使用杀虫剂。定义了0.53 ppm噻嗪酮的基线LC 50，并与其他田间采集进行了比较。已知或怀疑已被集中选择噻嗪酮的人群显示出在LC 50和特定诊断剂量下对杀虫剂的实质性耐受性，荷兰人群中的最高抗性因子为47倍。种群之间的变化，生物型和地理区域的原因进行了讨论，并强调了人类辅助运动的抗性基因的危险。
The insect growth regulator buprofezin was tested using a leaf-dip assay on immatures of Bemisia tabaci (Gennadius). The method was robust and repeatable, and baseline data were calculated for a laboratory strain and a number of field collections from Pakistan where the insecticide has not been used. A baseline LC 50 of 0.53 ppm buprofezin was defined and compared to other field collections. Populations known or suspected to have been intensively selected with buprofezin showed substantial tolerance to the insecticide at both the LC 50 and at specific diagnostic doses, with the highest resistance factor of 47 fold in a population from the Netherlands. Reasons for the variation between populations, biotypes and geographical areas are discussed and the dangers of human-assisted movement of resistance genes are highlighted.
