摘要
目的大面积开展灭蟑后,及时掌握生物种群变化动态,为巩固灭蟑达标成果、制定防治对策提供科学防治依据。方法依据常年蟑螂密度监测(粘捕法)、3‰氯菊酯酒精药液药激法与现场查阅PCO蟑螂防治工作记录询问法获取蟑螂种群。结果13年前蟑螂种群本底调查德国小蠊仅占3.07%,13年后占67.11%。讨论造成德国小蠊这一生物种群质和量的变化,一是卵鞘随体携带生物孵化传播;二是繁殖速度快、量大,易被货物和物品夹带被动扩散;三是成虫主动转移扩散。另外,与不合理的使用杀虫剂导致生物种群间抗药性基因世代相传有一定关系。
Objective To develop some countermeasures for prevention and treatment of cockroaches by monitoring the population variation of cockroaches after the large-scale eradication. Methods Monitoring the population dynamics of cockroaches by sticky recapture method, drug induced method with 3‰ permethrin （alcohol liquid） and on-site inspection of cockroaches killed through PCO. Results lation density of cockroaches were 67. 11% while it was 3.07% The percentage of BlatteUa germanica in the poputhirteen years ago. Conclusion The reasons for the change of Blattella germanica are as follows, egg sheaths could be carried around where the Blattella germanica goes, Blattella germanica are so small that it could be easily hid in the goods and items, and its resistance to insecticide contributes to the augment of population density.
