摘要
梨小食心虫是为害我国北方地区果树生产的重要害虫,为明确甘肃地区梨小食心虫种群对常用杀虫剂的抗性水平,采用浸卵法测定了甘肃3个地区梨小食心虫田间种群对8种杀虫剂的敏感性,并分析了其抗药性状况。结果表明,梨小食心虫田间种群对乙基多杀菌素表现为中等水平抗性[抗性倍数(R_(R)=10.24~14.27)],对溴氰菊酯表现为低至中等水平抗性(R_(R)=8.85~11.44),对高效氯氟氰菊酯、氯虫苯甲酰胺和螺虫乙酯均表现出中等水平抗性(R_(R)=18.89~86.62),对阿维菌素、甲维盐和茚虫威均基本表现为高水平抗性(R_(R)=99.82~189.81)。研究结果可为果园科学合理用药防控梨小食心虫提供科学依据。
Grapholita molesta(Busck)is an important pest in fruit tree production in northern China.In order to determine the resistance level of G.molesta population to commonly used insecticides in Gansu Province,the sensitivity of field populations of G.molesta from three different areas to eight insecticides was determined by the egg dipping method and the status of insecticide resistance was analyzed.The results showed that field populations of G.molesta showed moderate resistance to spinetoram(R_(R)=10.24-14.27),low to moderate resistance to deltamethyrin(R_(R)=8.85-11.44),moderate resistance to lambda-cyhalothrin,chlorantraniliprole and spirotetramat(R_(R)=18.89-86.62),and high resistance to abamectin,emamectin benzoate and indoxacarb(R_(R)=99.82-189.81).The results provide a scientific basis for the scientific and rational application of insecticides in the control of G.molesta in orchards.
