Attractant composition for preventing and treating spodoptera frugiperda and application of attractant composition
A technology of Spodoptera frugiperda and attractant, which is applied in the fields of attracting pests, chemicals for biological control, application, etc., can solve the problems of large regional uncertainty, influence of wind direction and wind speed, etc., and achieves the improvement of trapping effect.

 Example 1 : Test of different attractant formulations on the lure and monitoring effect of Spodoptera frugiperda
 Test location: the core area of corn planting in Laibin City, Guangxi, where corn is planted contiguously.
 Test method: Prepare the formula in Table 1 into lures and place them in boat-type traps. The traps are separated by about 10 meters and the height above the ground is 1.5 meters. Random block design is adopted. Each treatment is repeated three times, and the investigation is continued for 15 days. In the morning, the number of insects trapped by each trap was counted, and the fallen armyworm trapped by the trap was cleared, and the total amount of trapping was recorded.
 Table 1 attractant formula
 For the analysis of test results, see Table 1 and figure 1 .
 From Table 1 and figure 1 It can be seen that the combination of sex pheromone and odorant can improve the trapping effect of the lure ...
 Example 2: Experiments on the Lure and Monitoring Effect of Different Attractant Formulas on Spodoptera frugiperda
 Specific test method with reference to embodiment 1.
 Table 2 attractant formula
 Analysis of test results: For details, see figure 2 .
 Depend on figure 2 It can be seen that the different ratios of linalool oxide and methyl salicylate have a more obvious impact on the attracting effect: when the ratio of linalool oxide and methyl salicylate in formula 11 is 1:4, the attracting effect is poor, The total number of traps was 285; while formulas 12, 13, and 14 had better attracting effects, especially when the ratio of linalool oxide and methyl salicylate was 4:1, the attracting effect was the best, and the total amount of trapping was 331 .
