Most studies on efficacy of fungal pathogens and predatory mites against Tetranychus urticae have been done on individual species in the laboratory. We evaluated fungi and predatory mites separately and together against glasshouse populations of T. urticae on chrysanthemum plants. First, effectiveness of the fungal pathogens Beauveria bassiana (Bb88) and Metarhizium anisopliae (Ma129) was compared; then, effectiveness of the predatory mites Phytoseiulus persimilis and Neoseiulus californicus. Based on the results, N. californicus and isolate Ma129 were selected and evaluated in combination. In all experiments, treatment effects were assessed for eggs and motile stages of T. urticae.

昆虫病原真菌与捕食性螨类联合应用对菊花二斑叶螨的生物防治

大多数关于真菌病原体和捕食性螨虫对二斑叶螨功效的研究都是在实验室中针对单个物种进行的。我们分别评估了真菌和捕食性螨虫，并针对菊花植物上温室二斑螨种群进行了综合评估。首先，比较了真菌病原体白僵菌(Bb88) 和金龟子绿僵菌(Ma129) 的有效性；然后，捕食性螨类Phytoseiulus persimilis和Neoseiulus californicus的有效性。根据结果​​，选择加州猪笼草和分离株Ma129并进行组合评价。在所有实验中，评估了二斑玳瑁虫卵和活动阶段的处理效果。
