【摘要】 采用问卷和实地调查相结合的方法调查了福寿螺(Pomacea canaliculata)在四川稻区的分布和危害,并就现有化学杀螺剂进行了药效评价和综合防控技术的效果评价。结果表明,福寿螺目前在四川省16个地区均有分布,以成都、乐山、泸州等地福寿螺的危害较为严重。田间药效试验发现,杀螺胺乙醇胺盐对稻田福寿螺防效最高,达86.74%,而杀螺胺、四聚乙醛等防效相对较差。综合防控措施的灭螺效果为89.73%～93.64%,保苗率56.13%～80.36%,每667m2挽回经济损失553.21元。福寿螺在四川省分布广,化学杀螺剂需交替使用,综合防治技术措施行之有效。更多还原

【Abstract】 Distribution and hazards of the golden apple snail(Pomacea canaliculata) was investigated in Sichuan by using a combination of questionnaires and field surveys.The plot experiment was adopted to evaluate the effect of chemical molluscicide.And the evaluation of the integrated control technology was carried out by large area test.It was found that P.canaliculata occurred in 16 regions of Sichuan and damaged seriously in Chengdu,Leshan and Luzhou.Molluscicide screening showed that control effect of 70% wettable powder formulation of niclosamide-clamine was the highest,which reached 86.74%.The control effect of niclosamide and metaldehyde was next to that of niclosamide-clamine.After adopting the integrated control techniques,the overall control efficiency in rice field was up to 89.73%-93.64%,and seedling survival rate was between 56.13% to 80.36%,the economic loss for 553.21 yuan/667 m2 was retrieved.P.canaliculata was widely distributed in Sichuan.The chemical molluscicide was suggested to be used interchangeably,and the integrated control measures are effective.更多还原
