| 摘 要： | 蜗牛为间隙性暴发、杂食性软体动物，同型巴蜗牛在南京1年发生1代，2次危害高峰：6～7月；9～10月。春季取食茄果类、瓜类嫩叶，夏秋季取食十字花科蔬菜。转移到沟边时，以取食杂草为生。蜗牛发生和危害轻重受温湿度、食料等环境因素影响很大，高峰期虫口密度可达43．2头／m2，1棵大白菜上最多有45头，受害严重的蔬菜不能上市。防治以综合防治为好。衣业防治措施是清沟铲草、清洁田园；药剂防治可用6％密达颗粒剂，2％灭旱螺颗粒剂和8％灭蜗灵颗粒剂等。

| Abstract: | Snails are mollusks which are intermittent eruption and omnivorous. In Nanjing common garden snail emerges once a year, and has two harm cli-mares from June to July and September to October. In spring snails choose tender leaves of solanberry and melon crops as their feeds. In summer they choose cruciferous vegetables as their feeds. When moving to the edges of ditches, they will depend on rank grasses to live. The snail's germination and harm degree of serious ness are greatly influenced by humiture, foodstuff, and the other environment factors. During the climax periods insect density can reach 43. 2 heads/m2. There are 45 heads in one Chinese cabbage at most, and the vegetables which are greatly damaged can not be on the market. Integrated controlling is the best way. The agricultural controlling measures are to clean the ditches, fields and gardens, to destroythe weeds; the chemical controlling can use 6% Mi-Da granular formulation, 2%Mie-Han-Luo granular formulation and 8% Mie-Wo-Ling granular formulation,and so on. |
