以广州市郊、翁源、汕头市郊、四会、花都和始兴等地水稻三化螟对敌百虫、乐果、杀虫双、杀虫单和巴丹等杀虫剂的抗药性进行测定，结果表明：这些地区的三化螟幼虫对上述杀虫剂抗性水平都不高，但不同地区的水稻三化螟种群对同一种药剂反应有较明显差异，且抗药性的发展与当地施药水平有密切关系，耐药性的增长在年度间也有递增的趋势，翁源县的王化螟对乐果、巴丹、杀虫双尚处于敏感蚧段，而其它地区则存在种群对杀虫剂的异质性，翁源三化螟可作为杀虫剂的敏感种群。
The resistance of rice stem borer to insecticides such as trichlorfon, dimethoate, pest insecticide, pendimethalin and batan in the suburbs of Guangzhou, Weng Yuan, Shantou suburb, Sihui, Huadu and Siheung were studied The results showed that the resistance of the stem borer larvae to these insecticides was not high in these areas, but the response of the rice stem borer populations to the same pesticide in different regions was significantly different, and the development of resistance was similar to that of the local There was a close relationship between the levels of pesticide application and the increase of drug resistance in the year. The population of the kingdom borealis in Wengyuan County was still sensitive to the dimethoate, Insecticide heterogeneity, Wenger Borer can be used as a sensitive insecticide population.
