从农艺学和生态学的角度来看，研究农药暴露对瓢虫的毒性风险是重要的，因为幼虫和成虫瓢虫是食草害虫的主要捕食者（例如，蚜虫）在中国的各种作物。本文主要研究了昆虫生长调节剂氟铃脲对七星瓢虫的长期药效。用氟铃脲（单次施药）对棉铃虫2龄幼虫进行了72 h和33 d的毒力测定。七星花长期实验中的接触剂量是基于304 g活性成分（有效成分）的72小时急性半数致死率（导致50%死亡率的施用率）估计值。hm ~（-1）。七星花长期试验使用五种氟铃脲剂量作为治疗水平（72小时急性LR 50的1/50、1/100、1/200、1/400和1/800），以及溶剂对照和空白对照治疗。用于计算无明显效应施用率（NOER）的测量终点包括发育时间、孵化、化蛹、成虫羽化、存活和产卵数量。单因素方差分析结果表明，氟铃脲单次施用对黄瓜幼苗的生长有显著影响。在33天试验中，包括对发育持续时间的影响（NOER 1.52 g a.i. ha（-1））、孵化（NOER 3.04 g a.i. ha（-1））、化蛹（NOER 3.04 g a.i. ha（-1））和存活率（NOER 1.52 g a. i. ha（-1））。这些无观测效应率低于氟铃脲报告的最大田间施用量（135克活性成分）。ha（-1）），表明对有益节肢动物的潜在风险。
Studying the toxic risk of pesticide exposure to ladybird beetles is important from an agronomical and ecological perspective since larval and adult ladybirds are dominant predators of herbivorous pest insects (e.g., aphids) in various crops in China. This article mainly deals with the long-term effects of a single application of the insect growth regulator hexaflumuron on Coccinella septempunctata. A 72-h and a 33-day toxicity test with hexaflumuron (single application) were performed, starting with the second instar larvae of C. septempunctata. Exposure doses in the long-term experiment were based on the estimated 72-h acute LR50 (application rate causing 50% mortality) value of 304 g active ingredient (a.i.) ha(-1) for second instar larvae of C. septempunctata. The long-term test used five hexaflumuron doses as treatment levels (1/50, 1/100, 1/200, 1/400, and 1/800 of the 72-h acute LR50), as well as a solvent control and blank control treatment. The measurement endpoints used to calculate no observed effect application rates (NOERs) included development time, hatching, pupation, adult emergence, survival, and number of eggs produced. Analyzing the experimental data with one-way analysis of variance showed that the single hexaflumuron application had significant effects on C. septempunctata endpoints in the 33-day test, including effects on development duration (NOER 1.52 g a.i. ha(-1)), hatching (NOER 3.04 g a.i. ha(-1)), pupation (NOER 3.04 g a.i. ha(-1)), and survival (NOER 1.52 g a.i. ha(-1)). These NOERs are lower than the reported maximum field application rate of hexaflumuron (135 g a.i. ha(-1)) in cotton cultivation, suggesting potential risks to beneficial arthropods.
