Paederus fuscipes is a general predator in rice fields and a non-target organism of chlorantraniliprole, an effective insecticide for insect-pest control in paddy fields. Pesticide hazards to non-target organisms have been a growing global problem for decades. This study was designed to evaluate the toxicity of chlorantraniliprole at lethal and sublethal levels against P. fuscipes larvae and adults. The LC₅₀ of chlorantraniliprole against P. fuscipes adults and larvae were respectively 535.49 and 111.24 mg a.i. L⁻¹, which is higher than the dosage recommended for use in the field (59.38 mg a.i. L⁻¹), but the LC₃₀ and LC₁₀ for larvae are lower than the recommended field dose which showed that the sublethal effects on immature stages are inevitable. Treatment at larval stage with LC₃₀ of chlorantraniliprole significantly elongated the pre-imaginal developmental and pre-oviposition periods. Also, adults exposed directly to chlorantraniliprole oviposited significantly less number of eggs in both LC₁₀ and LC₃₀ treatments. Furthermore, the larval predation efficiency and female bodyweight were also reduced due to exposure to sublethal doses. Meanwhile, the activities of antioxidant (SOD, POD and CAT) and detoxification (P450, AChE and GST) enzymes were also significantly affected by the exposure to these sublethal concentrations. These findings showed that sublethal doses of chlorantraniliprole adversely influenced P. fuscipes development and physiology, and therefore its use as part of integrative pest management should be given further considerations.

Paederus fuscipes是稻田的总捕食者，也是稻田防治害虫的有效杀虫剂氯虫苯甲酰胺的非靶标生物。几十年来，农药对非目标生物的危害一直是一个日益严重的全球问题。本研究旨在评估氯虫苯甲酰胺在致死和亚致死水平对褐斑夜蛾幼虫和成虫的毒性。的LC ₅₀对氯虫苯甲酰胺的P.蝽成虫和幼虫分别为535.49和111.24毫克的AI大号^-1，这比推荐用于在现场使用（59.38毫克的AI L中的剂量更高^-1），但LC ₃₀和LC ₁₀幼虫的剂量低于推荐的现场剂量，这表明对未成熟阶段的亚致死效应是不可避免的。在幼虫阶段用氯虫苯甲酰胺的LC ₃₀处理显着延长了成虫前发育期和产卵前期。此外，直接暴露于氯虫苯甲酰胺的成虫在 LC ₁₀和 LC _{30 中}产卵的数量显着减少治疗。此外，由于暴露于亚致死剂量，幼虫的捕食效率和雌性体重也降低。同时，暴露于这些亚致死浓度下也显着影响抗氧化剂（SOD、POD 和 CAT）和解毒（P450、AChE 和 GST）酶的活性。这些发现表明，亚致死剂量的氯虫苯甲酰胺对褐斑夜蛾的发育和生理产生不利影响，因此应进一步考虑将其用作综合害虫管理的一部分。
