二化螟（Chilo suppressalis，步行者;鳞翅目：草螟科）是我国水稻的主要害虫之一。昆虫在其管理中起着重要作用。我们描述了我们如何监测C的电阻。2014-2016年，中国江西、湖北和湖南省7个田间种群对4种杀虫剂的敏感性。三唑磷、杀虫单和阿维菌素的抗药性监测以点滴法为宜。传统的水稻浸苗法检测氯虫苯甲酰胺效果不理想，因此改用人工饲料掺入法。一旦建立了基线毒性数据，这种新方法就比其他方法提供了更一致的结果。2014年至2016年，所有种群对三唑磷均具有中度至高度抗性。两个种群的杀虫单抗性从2014年的低水平上升到2016年的中等水平，其他五个种群始终表现出中等至高水平的抗性。3个种群的阿维菌素抗性从2014年的敏感或低水平上升到2015-2016年的中度水平，其他种群的抗性水平为中至高水平。对氯虫苯甲酰胺的耐药性从2014年的敏感或低水平上升到2016年的中度至高度水平。这些结果表明，应根据具体地点的需要制定抗性管理策略。建议在这些地区禁用有机磷杀虫剂，限制沙蚕毒素、大环内酯类抗生素和双酰胺类杀虫剂的使用，对其他未产生抗药性的杀虫剂，如乙基多杀菌素和甲氧虫酰肼等，应合理轮换使用，以延缓抗药性的发展。
Chilo suppressalis (Walker; Lepidoptera: Crambidae) is one of the most damaging rice pests in China. Insecticides play a major role in its management. We describe how we monitored the resistance of C. suppressalis to four insecticides in seven field populations from Jiangxi, Hubei, and Hunan Provinces, China, in 2014-2016. The topical application method for resistance monitoring was suitable for triazophos, monosultap, and abamectin. The conventional rice seedling dipping method proved ineffective for testing chlorantraniliprole so the new artificial diet incorporation method was substituted. This new method provided more consistent results than the other methods, once baseline toxicity data had been established. All populations had moderate to high resistance to triazophos from 2014 to 2016. Monosultap resistance in two populations increased from low in 2014 to moderate in 2016 and the other five populations showed moderate to high-level resistance throughout. Abamectin resistance in three populations increased from sensitive or low in 2014 to moderate in 2015-2016, and the other populations had moderate to high levels of resistance. Resistance to chlorantraniliprole increased from sensitive or low in 2014 to moderate to high in 2016. These results suggested that resistance management strategies should be developed according to the needs of a specific location. It was suggested that, in these localities, organophosphate insecticides should be prohibited, the application of nereistoxin, macrolide antibiotic, and diamide insecticides should be limited, and other insecticides, including spinetoram and methoxyfenozide, that exhibited no resistance should be used rationally and in rotation to delay resistance development.
