摘要
蛞蝓（Agriolimax agrestis）成为重要的农业害虫，正引起高度重视。根据调查“常见危害农作物的蛞蝓主要有黄蛞蝓（Limax flavus Linnaeus）、双线嗜粘液蛞蝓（Phiolmycus bilineatus Bonson）和野蛞蝓（Agriolimax agres-tis Linnaeus）”，以野蛞蝓尤为突出。蛞蝓繁殖过程比较复杂。对蛞蝓繁殖习性观察研究论述归纳概括为：蛞蝓一年发生2～6个世代，世代重叠复杂。由越冬成体或幼体发育为成体后，在4月中旬至6月中旬交尾，交尾后2～3 d 开始产卵，隔1～2 d 产卵1次，卵产在潮湿荫蔽土块缝隙2～4 cm 深处。每处产卵数粒至数十粒，卵聚集一堆。产卵期30～80 d，最长160 d 以上。成体一生产卵数量因环境条件不同而有差异，在60～400粒之间。温度在12～20℃、土壤含水量在20％～30％时最适合蛞蝓生长发育活动。
Abstract
Agriolimax agrestis has become an important agricultural pests,is causing attaches great impor-tance.According to the survey,there are mainly Chinaˊs common harm crops Agriolimax agrestis are Limax fla-vus Linnaeus,Phiolmycus bilineatus Bonson and Agriolimax agrestis Linnaeus,especially Agriolimax agrestis. Agriolimax agrestis’s breeding process is complicated.Based on the general scholars about Agriolimax agrestis breeding habits inductive observational study,Summarized as follows:Agriolimax agrestis has two-six genera-tions,generationgs are complicated.After overwintering adult or larval developed,In the middle of the middle of April to June mating.After 2 ~3 days began to lay eggs,Once every 1 to 2 days laying eggs,Eggs on sha-ded damp clods gap 2 ~4 cm deep.Each spawning several to dozens of grain.Eggs are gathered in a heap. Spawning period 30 ~80 days,160 days longest.Adult life spawning quantity,is different due to different en-vironmental conditions between 60 ~400.In 12 ~20 ℃ temperature,soil moisture content in 20% ~30%when the most suitable slug growth and development activities.
