上海市杨浦区2014—2020年德国小蠊抗药性变化研究

The resistance dynamics of Blattella germanica in Yangpu District of Shanghai from 2014 to 2020

摘要

摘要:
目的了解上海市杨浦区德国小蠊2014—2020年对常用杀虫剂的抗药性变化情况，为灭蟑杀虫剂的合理使用提供依据。
方法 2014、2017、2020年分别在杨浦区的2处农贸市场采集德国小蠊带回实验室饲养，采用WHO推荐的药膜法检测德国小蠊对常用杀虫剂的抗药性。
结果 2014、2017、2020年杨浦区德国小蠊对高效氯氰菊酯的抗性倍数分别为6.96、4.39、7.26，对氯菊酯的抗性倍数分别为10.41、6.71、5.24，对残杀威的抗性倍数分别为2.28、3.16、1.01。
结论 2014—2020年杨浦区德国小蠊对氯菊酯和残杀威的抗药性有所下降，对高效氯氰菊酯的抗药性维持在低抗水平。应注重综合治理，轮换使用杀虫剂，以延缓其抗药性升高。

Abstract:
Objective To investigate the resistance dynamics of Blattella germanica to commonly used insecticides in Yangpu District of Shanghai during 2014‒2020， and to provide the basis for the rational use of insecticides against cockroaches.
Methods Blattella germanica was captured in two farmer’s markets in 2014， 2017 and 2020. The residual film method recommended by WHO was used to test resistance of Blattella germanica to the insecticides.
Results In 2014， 2017 and 2020， the resistance ratio of Blattella germanica in Yangpu District was 6.96， 4.39， 7.26 to beta-cypermethrin， 10.41， 6.71， 5.24 to permethrin， and 2.28， 3.16， 1.01 to propoxur.
Conclusion The resistance of Blattella germanica to permethrin and propoxur decreases， and the resistance to beta-cypermethrin keeps at low level. Comprehensive management and rotation of insecticides should be implemented to delay the increase of resistance.
