摘　　要：[目的]综合评价黄板和性诱剂对斑潜蝇和小菜蛾的防治效果,为大面积科学推广使用该类技术防治害虫提供参考。[方法]通过田间调查和结构式访谈对通海县蔬菜主产区使用黄色粘虫板和小菜蛾性诱剂复合配置防治靶标害虫斑潜蝇和小菜蛾的防治成本、农药减少情况、诱集效果以及对非靶标昆虫的影响等进行综合评价。[结果]黄板对斑潜蝇和性诱剂对小菜蛾均具有良好的诱集效果,诱集数量分别为3 414±720和(219±157)头/张。在3种不同防治方法中,单独使用农药的防治成本最高,为(10 099.5±2 752.5)元/hm2,其次是黄板+诱芯配套使用,为(1 125.0±465.0)元/hm2,单独使用黄板的防治成本最低,为(450.0±186.0)元/hm2。不使用黄板+诱芯防治时,农药使用次数和费用分别为(15.0±2.7)次和(12 070.5±2 136.0)元/hm2;兼用黄板+诱芯防治时,农药的使用次数和防治费用分别减少5.7次和4 618.5元/hm2。诱集的益虫与靶标害虫的比例(益害比)为1∶1 131,表明黄色粘虫板和小菜蛾性诱剂分别对靶标害虫斑潜蝇和小菜蛾的诱集效果显著高于非靶标昆虫。[结论]综合来看,采用粘虫色板附着诱芯的防治方法不但诱集效果良好而且操作简单,比以往单独使用粘虫色板和性诱捕器节约防治成本,是目前较实用的一种害虫诱杀复合配置方法,具有良好的应用前景和推广价值。[ Objective ] To evaluate the control effect of yellow sticky cards and sex pheromone on Plutella xylostella and Liriomyza spp. , which can provide reference for large area extension of the technique. [ Method] The integrated assessment of trapping efficiency of colored sticky cards and sex pheromone on Liriomyza spp. and Plutella xylostella was conducted by field surveys and structured interview in Tonghai County, Yunnan Province, China. [ Result] The results showed that yellow sticky cards and sex pheromone have strong power of trapping Liriomyza spp. and Plutella xylostella 3 414 ±720 and （219 ± 157） head/piece, respectively） ; the control cost by the usage of pesticide is the highest, （ 10 099.5 ± 2 752.5 ） yuan/hm^2, yellow sticky cards and sex pheromone takes the second place, （ 1 125.0 ± 465.0 ） yuan/hm^2, the control cost by the usage of yellow sticky cards is the lowest, （450.0 ± 186.0） yuan/hm^2. Without the usage of yellow sticky cards and sex pheromone, pesticide application times and costs are （15.0±2.7 ）times and （12 070.5 ± 2 136.0） yuan/hm^2 ; combined with usage of yellow sticky cards and sex pheromone, pesticide application times and costs reduce by 5.7 times and 4 618.5 yuan/hm^2. The ratio of trapped beneficial insects and target pests was 1：1 131, which showed that the negative effect of yellow sticky cards and sex pheromone on the non-target insects was very limited. [ Conclusion] The trapping approach has become popular among all the local farmers. Looking at the above factors, the trapping technology has strong application prospect and promotion value in pest control field.
