江苏海涂苇田芦毒蛾的生态控制

The factors of the growth and decline of the population of Laelia coenosa candida and its ecological control in Jiangsu beach

１９９２～１９９５年江苏海涂苇田的调查表明，芦毒蛾（ＬａｅｌｉａｃｏｅｎｏｓａｃａｎｄｉｄａＬｅｅｃｈ）种群数量消长的主要影响因子是糙叶苔（Ｃａｒｅｘｓｃａｂｒｉｆｏｌｉａｓｔｅｕｄ．）、苇田干湿度以及芦毒蛾黑卵蜂（ＴｅｌｅｎｏｍｕｓＬａｅｌｉａＷｕｅｔＨｕａｎｇ）和寄生菌等。提出了以生态控制为基础的综合防治措施，包括因地制宜地赶火烧滩；利用苇田内高湿或浅灌消灭越冬幼虫；清除糙叶苔；保护和利用芦毒蛾黑卵蜂和其他防治措施的协调运用等。

ase on the present study,the main factors affecting the population of Laelia coenosa candisa Leech are as follows:the state of the breeding of Carax scabrfolia Steud.in the field;the state of the moisture of the field in the duration of the overwinter;the state of the occurrence of Telenomus laelia Wu et Huang;the deep of the water in the field in the growing period of Laelia coenosa candida. An integrated method based on ecological control is proposed.The control results showed that this method is effective and possessed good economical and ecological benefits.
