温室内利用啤酒诱杀蛞蝓的研究

Study on killing slugs with beer in greenhouse

试验利用5种不同浓度的啤酒及50%啤酒加0.4%糖的诱杀剂谤杀蛞蝓,以清水为对照,测定其影响及效果。结果表明:啤酒浓度越高诱杀效果越显著,诱杀效果越好,如1 00%啤酒比50%啤酒诱杀蛞蝓死亡率高10.37%。从不同浓度的啤酒对蛞蝓虫体大小诱杀效果看,浓度为90%的啤酒对幼年虫体的诱杀效果好。在同一浓度下的啤酒中加入0.4%的糖,会增加蛞蝓4.72%的死亡率。

Taking water as CK, attractive toxicants of beer treatments with different concentrations were used to kill slugs. The resultsshowed that the treatment with higher concentration of beer got the better killing effect. For example, the slug mortality of 100% beertreatment was more than 50% beer treatment by 10.37%. From the aspect of capturing effect to body size of slugs, 90% concentration hadbetter killing effect about the Juvenile worms. Adding 0.4% sugar in the same concentration of beer increased the mortality rate of 4.72% of slugs.
