野蛞蝓的发生与防治

野蛞蝓喜湿怕光，多发于低洼湿润的粘土地或壤土地，砂土地则很少发生。主要为害棚室蔬菜的幼苗、嫩叶和嫩茎。将叶片吃成孔洞或缺刻，咬断嫩茎和生长点，使整株枯死，常造成缺苗断垄。同时，排泄粪便，分泌粘液污染蔬菜，引起腐烂，使蔬菜品质降低。防治上应坚持以农业防治、物理防治、生物防治为主，化学防治为辅的无害化控制技术。

Occurrence and control of wild Agriolimax agrestis

Agriolimax agrestis hkes wet and dislikes light, are usually generated in the low-lying wet clay and loam, but rarely occurs in sand land. They usually cause damages on seedlings, leaves and stems of greenhouse vegetables by eating the leaves into a hole or nick, cutting stems and growing point, making entire plant withered dead, often resulting in sprout deficiency. At the same time, ex- cretion and mucus secretion should pollute the vegetables and cause decaying so that the quality will be reduced. Prevention and con- trol of the insect should focus on comprehensive harmless control technology including the agricultural control, physical control, bio- logical control, supplemented by the chemical control.
