摘要
目的 :分析比较两种方法监测蝇密度的结果及差异。方法 :腐鱼酱饵法和糖醋饵 +粘捕法。结果 :腐鱼酱饵法监测的蝇种以大头金蝇 ( 34% )、丝光绿蝇 ( 34% )、巨尾阿丽蝇 ( 9% )为主 ;糖醋饵 +粘捕法以家蝇 ( 41% )、丝光绿蝇 ( 2 3% )、大头金蝇 ( 13% )为主。两种监测方法蝇种的季节消长走势基本一致 ,两组监测数据平方根转换后呈高度相关 (P <0 .0 5 ) ,除糖醋饵 +粘捕法个别年份外 ,蝇密度指数均与温度有直线回归关系 (P <0 .0 5 )。结论 :糖醋饵 +粘捕法能反映主要防制蝇种家蝇、大头金蝇、丝光绿蝇的种群变化 ,便于统一和比较 ,其结果与传统的腐鱼酱饵法相比更具有可比性。
Two methods of monitoring flies population density were carried out in Shanghai.The results showed that Chrysomya megacephata (34%), Lucilia sericata (34%) and Aldrichina grahami (9%) were attracted to a mixture of putrid fish and soybean sauce, and Musca domestica (41%), C. megacephata (23%) and L. sericata(13%) were attracted to a measure that compounded by a mixture of brown sugar and vinegar ,and a commercial sticky card. The flies population density of two methods varied with the seasons, and had similar chart. The flies population density of two methods had positive correlation, and the density of most of these years also has linear regression with temperature. The attraction of brown sugar and vinegar was more unvaried than that of putrid fish and soybean, so the combine measure is worthy to be recommended for monitoring flies population density , and can reflect the main specimens of flies of city and their changes with the seasons.
