摘　　要：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。Objective To ascertain the level of cockroach infestation in the City of Jining and determine the insecticide resistance,population distribution,seasonal variations,and density of cockroaches. Methods Cockroaches caught with glue traps were used to investigate the types of cockroaches and extent of their infestation.An Erlenmeyer flask was used to expose cockroaches to a film of pesticide to test resistance. Results Five thousand four hundred sticky traps were collected and 715 cockroaches were caught.All were Blattella germanica,consisting of 421 adults（58.9%） and 294 nymphs（41.1%）.Cockroach density was 0.13 per trap and the rate of infestation was 9.11%.Cockroach density peaked in May,June,July,and August.Infestation was worst in hospitals,followed by restaurants and hotels;density was lowest in residential areas.Cockroaches in the City of Jining were highly resistant to beta-cypermethrin but still susceptible to propoxur,deltamethrin,and dichlorvos. Conclusion Hotels,restaurants,and hospitals were heavily infested,and infestation is rapidly spreading to residential areas.Management of key industries should be enhanced and comprehensive measures should be taken to control the spread of cockroaches in the City of Jining.
