石河子垦区果树食心虫迷向技术

【目的】研究迷向丝对果园食心虫的迷向效果。【方法】2018年在石河子垦区以桃单植园和苹果单植园为研究对象,利用梨小食心虫和苹果蠹蛾的混合迷向丝进行防治,并使用3种食心虫的性诱剂,诱捕调查石河子垦区果树食心虫的发生种类及其种群消长动态。【结果】桃园中果树食心虫的优势种群为梨小食心虫;苹果园优势种群为梨小食心虫和苹果蠹蛾,石河子垦区桃园和苹果园未悬挂迷向丝的对照区域虫口诱集数量均高于悬挂迷向丝的试验区域。【结论】石河子垦区桃园和苹果园利用悬挂迷向丝作为防治手段效果显著。

Study on the Mating Disruption Control Technology of Fruit Borer in Shihezi Reclamation Area

【Objective】 To clarity the control effect of the Grapholita molesta and the Cydia pomonella with mating disruption in fruit orchards.【Methods】The single planting orchards of flat peach and apple were used as the research objects and the control was carried out by using the mixed labyrinth of the baited core and codling moth in 2018 in Shihezi reclamation area. The growth and decline situation of carnivore in fruit trees were investigated by using three kinds of pheromone trap.【Results】The results showed that the dominant species in the peach orchards were pear carnivore and codling moth. The number of insects which were trapped in the control area of peach orchard and apple orchard with unsuspended labyrinth was higher than that in the experimental area with suspended labyrinth. 【Conclusion】 In Shihezi reclamation area, peach orchards and apple orchards using hanging mating disruption as control means have remarkable effect, and the mating disruption technology is worth popularizing.
