新疆果树害虫香梨优斑螟研究进展

Research Progress of Euzophera pyriella

香梨优斑螟是新疆重要的果树害虫之一,严重危害库尔勒香梨。通过总结国内外相关文献和实地调查,综述香梨优斑螟发生与危害特点、形态特征和生物生态学特性,总结生产中使用的各种防治措施,提出各种防治措施协调使用的综合管理实施方案,指出该害虫的发生与腐烂病、冻害、栽培管理措施、寄主情况等关系密切,防治难度大,急需开发性引诱剂、提高灯光诱杀效果、筛选特效化学农药和进行有害生物风险分析。

Euzophera pyriella is a primary reason causing the death of fragrant pear in Xinjiang.On the basis of the literature and field survey,this paper reviewed and summarized occurrence and damage of the pest,and morphology and biology of the insect.Additionally,the control measures,used in agriculture production,were also summarized.Furthermore,we put forward an integrated pest management measure.It was pointed out that the occurrence of E.pyriella was closely related with pear valsa canker,freeze injury,cultivation and management measure,host situation,and so on.Control of E.pyriella is very difficult.Some measures are urgently needed such as developing practical techniques of sex attractant,improving efficiency of light trap,screening specific pesticides and making pest risk analysis.
