摘要
目的通过对德国小蠊抗药性的检测,合理用药,从而控制蟑螂密度。方法根据蟑螂抗药性监测方案采用药膜法进行检测;利用化学防治,进行杀灭效果研究。结果德国小蠊为绝对优势种,德国小蠊现场品系对残杀威、高效氯氰菊酯和乙酰甲胺磷抗性系数分别是0.89、4.78和0.64,均属于低度抗性。经现场用药处理后德国小蠊得到有效控制。结论根据抗性结果,合理用药与环境治理相结合能在较长时间内有效控制蟑螂密度。
Objective To control the density of cockroach by detecting the resistance of Blattella germanica and rational administration.Method Using drug films to detect the drug resistance of cockroach,study the killing efficacy by chemical control.Results Blattella germanica was the dominant species and the resistance ratio of tested wild strains to propoxur,Lambda-cyhalothrin and acephate were 1.20,5.66,5.14 and 5.10 respectively,and all were low level of resistance.Conclusions Rational administration according to resistance test,comprehensive ecological improvement can control cockroach density for a long time.
