有害生物稻水象甲的研究及综合防控体系构建策略——以广元地区为例

Strategy Construction of Comprehensive Control System on Rice Water Weevil,Lissorhoptrus oryzophilus Kuschel,in Guangyuan

近几年,广元地区出现了检疫性有害生物稻水象甲,对农作物生长造成了一定的危害,研究其发生、传播、危害特点及防控措施等很有必要.当前,农业生产实践中主要是利用化学药剂实施防控,不仅会对环境造成污染,还会影响粮食生产安全,因而构建常态化、环保化的防控体系意义重大.该文提出了生物防治、植物检疫、农业防治和物理防治等措施并举的综合防控体系,在有效防控稻水象甲,确保农业生产获得丰收的同时,保护自然环境.

In recent years,the rice water weevil,Lissorhoptrus oryzophilus Kuschel,aquarantine pest appeared in Guangyuan area and done some harm to crops,so it isnecessary to study the occurrence,spread,harm and control.The main method incurrent agricultural practice is to use chemical prevention and control,which not only may cause environment pollution,but also can affect the safety of grain production.Therefore the establishment of normal and environmental system is of great significance.This paper puts forward comprehensive prevention and control systemincluding biological control,plant quarantine,agricultural and physical methods,tocontrol rice water weevil effectively and obtain a good harvest,moreover,protectingthe natural environment.
