桃小食心虫与金纹细蛾不同性诱芯的诱蛾效果

Trapping efficiencies of different sex pheromone lures for Carposina sasakii Matsumura and Lithocolletis ringoniella Matsumura in apple orchards

【目的】筛选高效诱芯,研究其科学使用技术,为提高性诱剂诱捕目标害虫效果提供技术支撑。【方法】于2009-07―09,选用桃小食心虫2种诱芯及桃小食心虫与金纹细蛾的单一诱芯和复合诱芯,在陕西省白水县选择桃小食心虫和金纹细蛾混合发生的苹果园进行田间诱捕试验。【结果】桃小食心虫2种不同诱芯的平均日诱蛾量和不同时段诱蛾量均无显著差异,而诱蛾量的动态趋势有一定差异。桃小食心虫和金纹细蛾单一诱芯的诱蛾效果均极显著高于复合诱芯;不同时段诱蛾效果表现为,试验初期桃小食心虫单一诱芯的诱蛾量极显著高于复合诱芯,而金纹细蛾单一诱芯在整个试验期间诱蛾量均极显著或显著高于复合诱芯;单一诱芯和复合诱芯诱蛾量动态比较一致,单一诱芯的诱蛾高峰均高于复合诱芯。【结论】桃小食心虫2种诱芯都能起到诱集成虫的作用,但A诱芯能更好地监测成虫的发生动态。在桃小食心虫和金纹细蛾混合发生的果园,将2种诱芯分开使用效果较好。

【Objective】Selecting effective sex pheromone lure and understanding scientific application technique of sex pheromone lure is one of the keys to improve trapping efficiency of lures for target pest insects.【Method】Trapping efficiencies of two kinds of sex pheromone lures for Carposina sasakii Matsumura,and single lure containing only one sex pheromone for C.sasakii Matsumura or Lithocolletisringoniella Matsumura and combined lure containing two kinds of sex pheromones for above both insect pests were in-ves...
