| 摘 要： | 本文报道了大瓶螺的生态学特性、年生活史,分布与为害、产卵量、孵化率及发育起点温度,有效积温等。并提出了三种防治方案,认为以药剂防治为主。药剂防治中以茶籽饼或硫酸铜在插秧前期进行清田毒杀为最佳,此法价廉高效,低毒简便易行,值得推广.

| Abstract: | In recent years,Ampullaris gigas Spix has become a very serious mollusc pest threating the rice crop in Guangdong province. The paper deals with Ampullaria gigas Spix's ecological characteristics,annual lifehistory,liv- ing habits,fecundity of female adults,rate of hatch,threshold of development temperature,ef- fecfive accumulative temperature of hatch,and distribution and damage effects etc. Besides,the paper reports 3 kinds of control methods.There are.1.Poisoning method,2. Agricultural method,3.biological control of these The best one is the first method,which kills the molluscs by using Camellia oleifera seed brans or copper sulfate before rice seedlings are trans- planted.This method is hypotoxic,less expensive,convenient to use,and highly effective. |
