摘　　要：采用虫孔塞药、喷施药物、树干涂白、综合防治4种不同方式对核桃云斑天牛进行田间防治效果对比试验,围绕云斑天牛防控效果、核桃树体长势、核桃产量增幅、防治成本4个方面进行调查分析,并对防治效果进行评价。结果表明,综合防治防控效果最好,校正防效达92.4%,虫孔塞药方式防控效果略低,校正防效达90.7%,喷施药物和树干涂白均有防控效果但效果不佳;综合防治对核桃树体长势和产量增幅影响最大,虫孔塞药方式效果次之且差异不明显;综合防治成本显著高于虫孔塞药、喷施药物和树干涂白防治成本。因此,综合考虑防治效果和节约成本等重要因素,虫孔塞药方式是防治云斑天牛的最佳选择。A comparative experiment was conducted on the field control effects of four different methods,including insect hole plugging,spraying,trunk whitening,and comprehensive prevention and control,on walnut Batocera horsfieldi.The control effects of Batocera horsfieldi,walnut tree growth,walnut yield increase,and control costs,and the evaluation of the control effects were investigated and analysisd in this paper.The results showed that the comprehensive prevention and control effect was the best,with a corrected control effect of 92.4%.The pest hole plugging method had a slightly lower control effect,with a corrected control effect of 90.7%.Spraying drugs and whitening tree trunks both had control effects,but the effect was not good;The comprehensive prevention and control has the greatest impact on the growth and yield increase of walnut trees,followed by the method of plugging insect holes with pesticides,and the difference is not significant;The cost of comprehensive prevention and control is significantly higher than that of insect hole plugging,spraying drugs,and trunk whitening prevention and control.Therefore,considering important factors such as prevention and control effectiveness and cost savings,the method of plugging insect holes with pesticides is the best choice for preventing and controlling Batocera horsfieldi.
