Anystis baccarum (L.) [=Anystis agilis (Banks)] (Acari: Anystidae) is a common predatory mite recently identified in apple (Malus spp.) orchards and in vineyards (Vitus spp.) in Québec, Canada. Studies of its susceptibility to pesticides used in these crops need to be carried out to encourage integrated pest management programs. A laboratory evaluation of methoxyfenozide, acetamiprid, thiamethoxam, imidacloprid, spinosad, phosmet, carbaryl, and lambda-cyhalothrin showed that residues of lambda-cyhalothrin, phosmet, and carbaryl were highly toxic in 48-h petri dish bioassays. The field rate of lambda-cyhalothrin is 0.0184 g (AI) /liter, which is 26-fold the estimated LC50 of 0.0007 g (AI) /liter) for this predator. The field rate for phosmet is 0.6000 g (AI) /liter, which is 118-fold the LC50 for phosmet, which is 0.0051 g (AI) /liter), and the field rate for carbaryl is 1.960 g (AI) /liter, which is 784-fold the estimated LC50 of 0.0025 g (AI) /liter). Five other insecticides, methoxyfenozide, acetamiprid, thiamethoxam, imidacloprid, and spinosad, were evaluated and found to be nontoxic.
巴氏钝绥螨（学名：Anystis baccarum (L.) [=Anystis agilis (Banks)]，蜱螨亚纲：钝绥螨科）是一种常见的捕食性螨类，最近在加拿大魁北克省的苹果园（苹果属）和葡萄园（葡萄属）中被发现。需要对其对这些作物中使用的农药的敏感性进行研究，以推动综合虫害管理计划。对甲氧虫酰肼、啶虫脒、噻虫嗪、吡虫啉、多杀霉素、亚胺硫磷、西维因和高效氯氟氰菊酯的实验室评估表明，在48小时的培养皿生物测定中，高效氯氟氰菊酯、亚胺硫磷和西维因的残留具有高毒性。高效氯氟氰菊酯的田间施用量为0.0184克（有效成分）/升，是该捕食者估计半数致死浓度（LC₅₀）0.0007克（有效成分）/升的26倍。亚胺硫磷的田间施用量为0.6000克（有效成分）/升，是其LC₅₀（0.0051克（有效成分）/升）的118倍，西维因的田间施用量为1.960克（有效成分）/升，是估计LC₅₀（0.0025克（有效成分）/升）的784倍。对其他五种杀虫剂，即甲氧虫酰肼、啶虫脒、噻虫嗪、吡虫啉和多杀霉素进行了评估，发现它们无毒。
