摘要
目的 观察地笼使用对钉螺扩散的影响,为制定钉螺精准防控措施提供参考.方法 购买捕鳝者常用地笼20只,其中包装带编织地笼11只、塑料地笼7只、尼龙绳编织地笼2只.于适宜钉螺繁殖的2024年4月13、26、28日15:00至次日8:00,将20只地笼分别放置在浙江省平湖市新埭镇钉螺密度相对较高(≥1.00只/0.1 m2)和相对较低(<1.00只/0.1 m2)环境中,比较不同钉螺密度环境中不同材质地笼携带钉螺数量.结果 在钉螺密度相对较高环境中共放置地笼11笼·次,检获钉螺77只,平均7只/(笼·次)、2.15只/0.1 m2地笼,其中包装带编织地笼和塑料地笼平均钉螺携带数量为2.47只/0.1 m2地笼和0.37只/0.1 m2地笼;在钉螺密度相对较低环境中共放置地笼 24 笼·次,检获钉螺 8 只,平均 0.33 只/(笼·次)和0.09只/0.1 m2地笼;其中包装带编织地笼平均钉螺携带数量为0.12只/0.1 m2地笼,塑料地笼和尼龙绳编织地笼均未观察到携带钉螺.在钉螺密度较高环境中,地笼钉螺携带数量多于钉螺密度相对较低环境(Z=-4.019,P<0.01),包装带编织地笼在钉螺密度相对较高环境中的钉螺携带数量多于钉螺密度相对较低环境(Z=-4.086,P<0.01),不同材质地笼钉螺携带数量差异无统计学意义(Z=-1.873,P>0.05).结论 在有螺环境中使用地笼可导致钉螺扩散.
Abstract
Objective To examine the effect of ground cage use on Oncomelania hupensis spread,so as to provide insights in-to precision snail control.Methods Twenty ground cages that were frequently used to capture rice field eels were purchased,including 11 packaging tape-made cages,7 plastic cages and 2 nylon rope-made cages.The eel-capturing activity was mimicked,and 20 ground cages were assigned in settings with relatively high(1.00 snail/0.1 m2 and higher)and low snail densities(<1.00 snail/0.1 m2)in Xindai Township,Pinghu City,Zhejiang Province during the period from 15:00 to 8:00 of the following day on April 13,26 and 28.The numbers of snails carried by different types of ground cages were compared in settings with different types of snail densities using the rank-sum test.Results A total of 11 cage-times were assigned in settings with a high snail den-sity,and a total of 77 snails were captured,with a mean number of 7 snails in each cage-time and 2.15 snails in 0.1 m2 ground cage.The mean numbers of snails carried by packaging tape-made and plastic cages were 2.47 snails/0.1 m2 cage and 0.37 snails/0.1 m2 cage,respectively.A total of 24 cage-times were assigned in settings with a low snail density,and a total of 8 snails were captured,with a mean number of 0.33 snails in each cage-time and 0.09 snails in 0.1 m2 ground cage.The mean numbers of snails carried by packaging tape-made cages were 0.12 snails/0.1 m2 cage;however,no snails were carried by plastic or nylon rope-made cages.The number of snails carried by ground cages was higher in settings with a high snail density than in settings with a low snail density(Z=-4.019,P<0.01),and the number of snails carried by packaging tape-made cages was higher in set-tings with a high snail density than in settings with a low snail density(Z=-4.086,P<0.01).No significant differences were found in the numbers of snails carried by different types of ground cages.Conclusion The use of ground cage in snail habitats is a contributor to snail spread.
