Multiple arthropod pests can affect the same crop in agricultural systems, requiring the integration of control methods. In the present study, the effects of residual exposure to four broad-spectrum insecticides/acaricides (azadiractin, abamectin, chlorfenapyr, and fenpyroximate) on immature (development and survival time) and adult females (longevity, fecundity, and fertility life table parameters) of the predatory mite Neoseiulus barkeri were evaluated. Additionally, the insecticides/acaricides were categorized according to their selectivity based on the classification proposed by the International Organization for Biological Control (IOBC) for assessing the susceptibility of arthropods in laboratory experiments. Method 004, proposed by the Insecticide Resistance Action Committee (IRAC), was adopted for the bioassays with predators exposed to insecticide-acaricide residues. Among the insecticides/acaricides studied, azadirachtin had minimal effects on immature and adult N. barkeri (all non-significant) and was considered harmless based on the classification of toxicity according to the standards/categories proposed by the IOBC. All other insecticides/acaricides affected immature and adult N. barkeri and were considered slightly harmful in terms of toxicity, according to the IOBC.
在农业系统中，多种节肢动物害虫会同时影响同一作物，这就需要整合控制方法。本研究评估了残留接触四种广谱杀虫剂/杀螨剂（印楝素、阿维菌素、氯氟吡氧乙酸和唑螨酯）对捕食性螨虫巴氏新小绥螨幼期（发育和存活时间）和雌成螨（寿命、产卵量和生育生命表参数）的影响。此外，根据国际生物防治组织（IOBC）提出的评估实验室中节肢动物敏感性的分类方法，对杀虫剂/杀螨剂进行了基于选择性的分类。采用昆虫抗药性行动委员会（IRAC）提出的方法 004 进行了暴露于杀虫剂-杀螨剂残留的捕食者生物测定。在所研究的杀虫剂/杀螨剂中，印楝素对巴氏新小绥螨幼期和成虫的影响最小（均无显著性），根据 IOBC 提出的标准/类别，按照毒性分类，被认为是无害的。根据 IOBC 的标准，所有其他杀虫剂/杀螨剂都影响巴氏新小绥螨幼期和成虫，被认为具有轻微毒性。
