Study on Trapping and Killing Technology of Wild Agriolimax agrestis on Cryptotaenia japonica Hassk in Protected Land
[Objective]Wild Agriolimax agrestis is a kind of pest in the modern protected land,which is increasingly harmful and difficult to control.It not only causes holes in Cryptotaenia japonica Hassk,but also pollutes the vegetable plants with feces and insects bodies,easy to cause gray mold,soft rot epidemic.To effectively prevent and control the harm of wild slugs,a lure killing experiment was conducted by mixing different fruit and vegetable slices with metaldehyde watered powder.[Method]Taking advantage of the fact that wild A.agrestis likes sweet and fragrant food,the experiment used three treatments of A,B and C as attractant,they are:orange slice + metaldehyde watered powder,apple slice+metaldehyde watered powder,Chinese cabbage cuts+metaldehyde watered powder,the control was C.japonica Hassk cuts and metaldehyde watered powder.Wild A.agrestis were trapped and killed for 7 consecutive days.The number of wild A.agrestis trapped and killed was checked and recorded every day.[Result]The results of SPSS software analysis showed that treatment A had the best effect with 96.3%entrapment efficiency,followed by treatment B with 90.6%entrapment efficiency.These two attractants can be used in vegetable production.However,the trapping and killing rate of treatment C was only 26.6%,which had no significant difference with the control.So it's not suggested to use this method.[Conclusion]Therefore,30 g orange slices and 3 g metaldehyde watered powder can be used in the protected land to lure and kill wild A.agrestis,and the effect is ideal.
