Stratiolaelaps scimitus (Womersley) and Cosmolaelaps brevistilis (Karg) (Acari: Laelapidae) are predatory mites of soil-inhabiting pests, mainly small insects. Fungus gnats fly species are found in greenhouse strawberry production and may be controlled with predatory mites, being important to know their compatibility with the pesticides used in strawberry crops. In this study, the compatibility of seven commercial pesticides used in strawberry cultivation with the predatory mites S. scimitus and C. brevistilis was assessed in laboratory conditions. Survival and oviposition rates were evaluated between 0.5 and 120 h after treatment (HAT). The results demonstrate that lambda-cyhalothrin treatment resulted in the lowest survival rate for both mites in the first evaluations, being moderately harmful, while spinetoran was slightly harmful to C. brevistilis. On the other hand, abamectin, azadirachtin, azoxystrobin + difenoconazole, iprodione and thiamethoxam were harmless for both mites and, oviposition rate was significantly different only at 72 and 120 HAT for S. scimitus and C. brevistilis respectively. These results may be used to develop guidelines for the adoption of selective pesticides in integrated pest management programs that conserves predatory mites.

草莓作物中使用的农药与掠食性螨Stratiolaelaps scimitus（Womersley）和Cosmolaelaps brevistilis（Karg）的相容性。

Stratiolaelaps scimitus（Womersley）和Cosmolaelaps brevistilis（Karg）（Acari：Laelapidae）是土壤害虫的掠食性螨，主要是小昆虫。大棚草莓生产中发现了真菌蝇种，并且可以用捕食性螨防治，这对于了解它们与草莓作物中使用的农药的相容性很重要。在这项研究中，在实验室条件下评估了草莓栽培中使用的七种商业农药与捕食螨S. scimitus和C. brevistilis的相容性。在治疗后（HAT）0.5至120 h之间评估存活率和排卵率。结果表明，在第一轮评估中，lambda-cyhalothrin治疗导致两种螨的存活率最低，对中度有害，而spinetoran对C略有危害。灯盏花 另一方面，阿维菌素，印苦dir子素，嘧菌酯+二苯并康唑，异丙洛酮和噻虫嗪对螨虫均无害，产卵率仅在72和120 HAT下分别对弯刀链霉菌和短螺旋梭菌有显着差异。这些结果可用于制定在有害生物综合防治计划中采用选择性杀虫剂的指南，以保护捕食性螨。
