Occurrence and Damage of Snails and Slugs in Protected Cultivation of Oncidium and Their Integrated Control

介绍了海南文心兰设施栽培中蜗牛和蛞蝓的种类、发生及为害规律,并提出以物理隔离法(水碗法、矿泉水瓶法)为主,辅以毒饵诱杀、药剂防治、农业防治和生物防治等措施相结合的综合防治技术。

Oncidium spp. are a new tropical orchid of great potential in Hainan since Hainan government had given priority to development of the tropical orchid industry in Hainan. Under cultivation facilities snails and slugs occur frequently and cause serious damage to Oncidium plants in Hainan. They have cause destructive damages to some poor-managed orchid gardens where Oncidium plants are 3 -5 years old. The species, occurrence and damage of snails and slugs in protected cultivation of Oncidium in Hainan are introduced. An integrated method is proposed to control the snails and slugs, including blocking their pathway with physical separation （bowl with water, plastic bottle）, toxic bait, chemical control, cultural control and biological control.
