Abstract Aleuroclava jasmini (Hemiptera: Aleyrodidae) is a major insect pest of paper mulberry (Broussonetia papyrifera) in Iran, negatively affecting its production. Considering the importance of oils in the integrated management programs of such pests, the present study examined the possibility of whitefly control on paper mulberry plant to assess mortality rate (MR), synergistic rate (SR), resistance rate (RR), and lethal concentration for 50% of the population (LC50) of oils and common insecticide in populations from four areas of Tehran, Iran (one susceptible and three non-susceptible). The best chemical treatments against A. jasmini adults and nymphs in paper mulberry plants were neem oil (1 ml L−1) mixed with deltamethrin (0.5 ml L−1) or with buprofezin (1 ml L−1). The neem, akylarylpolyglyglycol ether and volk oils mixed with deltamethrin or buprofezin also had synergistic effects on adults and nymphs of A. jasmini, respectively, in Azadi, Shahrake Gharb, and Vanak areas (non-susceptible populations), but with higher concentrations (> LC50) and lower SR than in Garm Dareh area (susceptible population). We observed that A. jasmini adults showed the greatest resistance to deltamethrin in Vanak area and nymphs of this pest to buprofezin in Shahrake Gharb area.

伊朗纸桑上常见的油剂和杀虫剂及其对香粉（Aleyrodidae）的抗性

摘要 Aleuroclava jasmini (Hemiptera: Aleyrodidae) 是伊朗纸桑(Broussonetia papyrifera) 的主要害虫，对其生产产生不利影响。考虑到油在此类害虫综合管理计划中的重要性，本研究研究了控制纸桑树粉虱的可能性，以评估死亡率 (MR)、增效率 (SR)、抗性率 (RR) 和致死浓度伊朗德黑兰四个地区（一个易感，三个非易感）中 50% 的人口 (LC50) 的油和常见杀虫剂。在纸桑树植物中对抗茉莉花成虫和若虫的最佳化学处理是印楝油（1 ml L-1）与溴氰菊酯（0.5 ml L-1）或丁苯丙酸（1 ml L-1）混合。印楝 在 Azadi、Shahrake Gharb 和 Vanak 地区（非易感种群），烷基芳基聚乙二醇醚和 volk 油与溴氰菊酯或 buprofezin 混合也分别对 A. jasmini 的成虫和若虫有协同作用，但浓度较高（> LC50）和SR 低于 Garm Dareh 地区（易感人群）。我们观察到，A. jasmini 成虫在Vanak 地区对溴氰菊酯表现出最大的抗性，而在Shahrake Gharb 地区，该害虫的若虫对buprofezin 表现出最大的抗性。
