广西甘蔗螟虫发生概况和动态变化

广西甘蔗对我国食糖安全起重要作用,而螟虫是影响甘蔗产业最重要害虫。因此,螟虫防治一直是科研工作者重点关注的科学问题,20世纪60年代以来研究者一直对螟虫预测预报、防治方法等进行了深入研究,但是几十年以来还是依赖化学防治为主,长期使用化学药剂,易导致害虫产生抗药性,污染环境破坏生态平衡。对螟虫种类、分布、为害特点等进行简述,重点分析广西甘蔗虫害预测预报、危害情况和防治方法等方面的历史和现状差异,并对现阶段螟虫防治存在的问题和未来发展提出了一些建议,望为广西甘蔗螟虫防治提供参考依据。

Occurrence Profile and Population Dynamics of Sugarcane Borers in Guangxi

Sugarcane in Guangxi plays a critical role in the sugar security in China,sugarcane borers are the most significant pest which impose huge impact on sugarcane industry.Therefore,sugarcane bores control has been the scientific issues that the scientists focused on all the time,and since the 1960s,researchers has been investigated the predication and control for sugarcane bores.However,for the past several decades,the chemical insecticide has always been the primary control strategies.The long-term application of chemical insecticide would cause pest resistance,environmental pollution and ecological imbalance.In this review,we summarized the species,distribution and the damage feature of sugarcane bores,particularly in the historical and current differences of sugarcane pest forecast,damage and control methods in Guangxi.What is more,some suggestions were put forward for the current problems and future development of stem borers control.This investigation may provide some support reference for the sugarcane bores control in Guangxi.
