济宁市蜚蠊侵害现况及抗药性调查

目的掌握济宁市蜚蠊侵害现况及其抗药性、种群分布、季节消长和密度等情况。方法采用粘捕法捕捉蜚蠊,调查其种类及侵害程度;采用三角烧瓶药膜接触法检测蜚蠊抗药性。结果本次共回收有效粘蟑纸5400张,捕获蜚蠊715只,均为德国小蠊,其中成虫421只(占58.9%),若虫294只(占41.1%);蟑螂总密度为0.13只/张,侵害率为9.11%;蜚蠊密度以5～8月最高。场所蜚蠊密度以宾馆最高,侵害率医院最高,其次是餐饮和宾馆,居民区最低。济宁市德国小蠊对高效氯氰菊酯已产生高抗药性,对残杀威、溴氰菊酯和敌敌畏仍然敏感。结论济宁市宾馆、餐饮、医院为蜚蠊高侵害场所,并有向居民区快速扩散的趋势,必须加强对重点行业的管理,采取综合性防制措施,控制蜚蠊扩散和蔓延。
