为解决温室黄瓜二斑叶螨 (Tetranychus urticae Koch)危害导致的作物减产问题，来自埃及的研究团队通过筛选土壤样本中的72株链霉菌，鉴定出两株高产阿维菌素 (abamectin)的S. avermitilis菌株EW8和T2（产量分别为42.7和29.6 μg/L）。实验证实其粗提物能有效杀灭螨虫各发育阶段，并通过诱导丙二醛 (MDA)升高引发 ...

为解决二斑叶螨 (Tetranychus urticae)对杀螨剂快速产生抗药性的难题，研究人员通过建立纯合种群，首次揭示了该物种在阿维菌素 (abamectin)压力下呈现显著的跨代适应不良表型。连续七代暴露于药剂的种群反而表现出更低抗性，且该表型在停药后持续两代。甲基化组分析显示其胞嘧啶甲基化水平极低 ...
