苏州市福寿螺发生规律及农田防控技术研究

Study on occurrence regularity and farmland control technology of Pomacea canaliculata in Suzhou City

福寿螺是近年来苏州市水稻及其他水生作物上的重要有害生物,由于其繁殖能力强,容易随水流扩散,目前生产上缺乏有效的监测和防控措施。本文通过野外调查和定点监测,初步摸清其在苏州的发生规律。在此基础上,积极开展农田综合防控技术研究,明确了水旱轮作、物理拦截、引诱灭螺、人工捡拾、药剂防控等具体防控措施,并提出下一步的防控思路,为农田防控福寿螺提供参考。

Pomacea canaliculate is an important pest on rice and other aquatic crops in Suzhou in recent years. Because of its strong reproductive ability,it is easy to spread with the water flow,and there is no effective monitoring and prevention and control measures in agricultural production. Through field investigation and fixed-point monitoring,the occurrence and damage regularity in Suzhou were preliminarily clear.In addition,the research on com prehensive prevention and control technology of farmland was actively carried out,and the specific prevention and control measures such as rotation of water and drought,physical interception,attracting and killing snails,manual picking up and pesticide prevention and control were clarified. The ideas of next step prevention and control were put forward to provide reference for the prevention and control of it in farmland.
