The present study evaluated insecticide resistance in field populations of onion thrips, Lindeman (Thysanoptera: Thripidae), collected from eight different onion-growing regions of Punjab, Pakistan. These field-collected populations were assessed for resistance development against eight commonly used active ingredients including deltamethrin, lambda-cyhalothrin, imidacloprid, acetamiprid, spinosad, spinetoram, cypermethrin, and abamectin. In leaf dip bioassays, adults showed varied levels of resistance towards different insecticides. Moderate or high levels of resistance to deltamethrin (58-86 fold), lambda-cyhalothrin (20-63 fold), and cypermethrin (22-54 fold) were observed in field populations. There were very low to moderate resistance levels to imidacloprid (10-38 fold), acetamiprid (5-29 fold), and abamectin (10-30 fold). The lowest levels of resistance were detected in thrips exposed to spinosad (3-13 fold) and spinetoram (3-8 fold). Insecticide resistance levels varied among populations collected from various geographic locations, but all populations exhibited elevated levels of resistance to deltamethrin. populations with higher resistance levels were most commonly found from the southern part of Punjab, Pakistan. Our findings revealed that spinosyns could be used as alternatives to conventional insecticides for the successful management of in onion fields.
本研究评估了从巴基斯坦旁遮普省八个不同洋葱种植区采集的葱蓟马（缨翅目：蓟马科）田间种群的抗药性。对这些田间采集的种群针对八种常用活性成分（包括溴氰菊酯、高效氯氟氰菊酯、吡虫啉、啶虫脒、多杀霉素、乙基多杀菌素、氯氰菊酯和阿维菌素）的抗药性发展情况进行了评估。在叶片浸渍生物测定中，成虫对不同杀虫剂表现出不同程度的抗性。在田间种群中观察到对溴氰菊酯（58 - 86倍）、高效氯氟氰菊酯（20 - 63倍）和氯氰菊酯（22 - 54倍）有中度或高度抗性。对吡虫啉（10 - 38倍）、啶虫脒（5 - 29倍）和阿维菌素（10 - 30倍）的抗性水平很低到中度。暴露于多杀霉素（3 - 13倍）和乙基多杀菌素（3 - 8倍）的蓟马中检测到的抗性水平最低。从不同地理位置采集的种群中，杀虫剂抗性水平各不相同，但所有种群对溴氰菊酯的抗性水平都有所提高。抗性水平较高的种群最常见于巴基斯坦旁遮普省南部。我们的研究结果表明，多杀菌素可作为传统杀虫剂的替代品，用于成功管理洋葱田中的蓟马。
