不同诱杀方法对砂糖橘实蝇的防控效果和效益分析

柑橘实蝇危害是肇庆柑橘产区蔓延和潜在爆发的重要检疫性害虫。物理方法可用于多种实蝇的监测和防治,但生产上缺乏对不同实蝇的诱杀效果评价。在肇庆地区砂糖橘园测试了不同物理诱杀方法对柑橘大实蝇和柑橘小实蝇的诱杀效果。结果表明,未挂果果园和挂果果园内性诱剂诱捕到柑橘小实蝇的数量分别为110、32头,食物诱剂的诱捕量为25.7、6头,黄板的诱捕量为24、5头,性诱剂诱捕到柑橘小实蝇的数量显著多于食物诱剂和黄板;相反,食物诱剂和黄板诱捕到的昆虫种类和数量多于性诱剂,并能诱捕到柑橘大实蝇。在10-12月期间,柑橘小实蝇的诱捕量出现两个高峰期,而柑橘大实蝇的诱捕量一直保持较平稳的状态。在防治成本上,第一诱杀周期...

Summary:柑橘实蝇危害是肇庆柑橘产区蔓延和潜在爆发的重要检疫性害虫。物理方法可用于多种实蝇的监测和防治,但生产上缺乏对不同实蝇的诱杀效果评价。在肇庆地区砂糖橘园测试了不同物理诱杀方法对柑橘大实蝇和柑橘小实蝇的诱杀效果。结果表明,未挂果果园和挂果果园内性诱剂诱捕到柑橘小实蝇的数量分别为110、32头,食物诱剂的诱捕量为25.7、6头,黄板的诱捕量为24、5头,性诱剂诱捕到柑橘小实蝇的数量显著多于食物诱剂和黄板;相反,食物诱剂和黄板诱捕到的昆虫种类和数量多于性诱剂,并能诱捕到柑橘大实蝇。在10-12月期间,柑橘小实蝇的诱捕量出现两个高峰期,而柑橘大实蝇的诱捕量一直保持较平稳的状态。在防治成本上,第一诱杀周期使用性诱剂、食物诱剂和黄板每667m^2的成本分别为55、40、40元,第二个周期后分别为15、40、40元,3种诱杀方法均未有有毒灭杀化学药剂接触果实。结合两种实蝇生命周期的全年发生规律,从未挂果果园管理开始,采用多种诱捕方法结合的综合防控措施是肇庆地区砂糖橘园有效防治柑橘实蝇,推进农药减量控害的经济、绿色植保技术。

Citrus fruit flies are a major kind of quarantine pest that spreads with a potential outbreak in citrus producing areas in Zhaoqing. A variety of fruit flies can be monitored and controlled by physical methods. However,there is a lack of effect evaluation of trapping fruit flies during production. In this study,the effects of different physical traps were tested for bactrocera minax and bactrocera dorsalis in the Citrus reticulate Blanco cv. Shatangju orchards in Zhaoqing. The results showed that in a non-fruiting orchard and fruiting orchard respectively,the numbers of bactrocera dorsalis trapped by sex pheromones were 110 and 32,25.7 and six by food attractants,and 24 and five by yellow sticky boards. While the number of bactrocera dorsalis
