The results showed that yellow sticky trap received the best trapping effect on adult B. odoriphaga, follow by blue and green sticky traps, while cyan and white sticky traps received worse effects. The yellow sticky trap settled at south position was most attractive to adult B. odoriphaga, which had significant differences with tho^e placed at east and north positions (P 〈 0.05 ) ; the yellow sticky trap at hanging height of 0 cm showed significantly higher attractive- ness than those at heights of 20 and 40 cm.展开更多
【目的】为探究黄色粘虫板对苹果绣线菊蚜(Aphis citricola Van der Goot)的诱捕效果以及诱集昆虫种类和数量,探明其应用价值和正确使用方法。【方法】于苹果年生长周期内悬挂黄板,并对苹果绣线菊蚜、其他害虫和天敌的种类及数量进行统...【目的】为探究黄色粘虫板对苹果绣线菊蚜(Aphis citricola Van der Goot)的诱捕效果以及诱集昆虫种类和数量,探明其应用价值和正确使用方法。【方法】于苹果年生长周期内悬挂黄板,并对苹果绣线菊蚜、其他害虫和天敌的种类及数量进行统计分析。【结果】整个试验阶段苹果绣线菊蚜诱捕数量仅(109.9±5.1)头·板-1,与其他昆虫相比,数量并不显著;其他害虫中,叶蝉诱捕数量最多,数量高于苹果绣线菊蚜;瓢虫、食蚜蝇、草蛉、蛇蛉等与苹果绣线菊蚜诱捕数量相当,以靶标害虫蚜虫计算,益害比为1:1.2,悬挂黄板会影响天敌控害效果;黄板对于蝇类诱捕量最多,证明蝇类也可能存在趋黄性;苹果花期悬挂黄板,主要诱捕的是授粉蜜蜂。【结论】黄板对苹果绣线菊蚜防控效果不显著,研究发现其他害虫可能存在趋黄性,其使用价值有待多方面评估。黄板诱杀具有广谱性,会影响自然条件下蜜蜂和天敌种群,在苹果开花期和天敌数量较多的果园应谨慎悬挂。展开更多
