Embodiment 1

[0024] Example 1 : Test of different attractant formulations on the lure and monitoring effect of Spodoptera frugiperda

[0025] Test location: the core area of ​​corn planting in Laibin City, Guangxi, where corn is planted contiguously.

[0026] 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.

[0027] Table 1 attractant formula

[0028]

[0029] For the analysis of test results, see Table 1 and figure 1 .

[0030] 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 ...

Embodiment 2

[0032] Example 2: Experiments on the Lure and Monitoring Effect of Different Attractant Formulas on Spodoptera frugiperda

[0033] Specific test method with reference to embodiment 1.

[0034] Table 2 attractant formula

[0035]

[0036] Analysis of test results: For details, see figure 2 .

[0037] 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 .

Abstract

The invention belongs to the field of attractants, and particularly relates to an attractant composition for preventing and treating spodoptera frugiperda. The invention discloses an attractant composition for preventing and treating spodoptera frugiperda. The attractant composition comprises sex pheromones, an odor substance and an auxiliary component, the sex pheromone is composed of (Z)-7-dodecene-1-alcohol acetate, (Z)-9-tetradecene acetate, (Z)-11-hexadecanol acetate and (Z)-9-dodecene-1-alcohol acetate, and the mass content ratio of (Z)-7-dodecene-1-alcohol acetate to (Z)-9-tetradecene acetate to (Z)-11-hexadecanol acetate to (Z)-9-dodecene-1-alcohol acetate is (0.01 to 0.05): (1 to 5): (0.1 to 1): (0.01 to 0.05); the odor substance is composed of linalool oxide and methyl salicylate, and the volume ratio of the linalool oxide to the methyl salicylate is (0.1-1): (0.1-1). The attractant composition provided by the invention can be used for trapping spodoptera frugiperda.

Description

technical field [0001] The invention belongs to the field of attractants, and in particular relates to an attractant composition for controlling Spodoptera frugiperda and its application. Background technique [0002] Spodoptera frugiperda has the characteristics of strong reproductive ability, wide range of hosts, rapid migration and great destructiveness. Adults of Spodoptera frugiperda have strong long-distance migratory ability and can fly about 100 kilometers per night. Affected by the number of adult populations and wind direction and speed, the occurrence area is highly uncertain. At present, the insect has been found in Yunnan, Guangxi, Guizhou and other places in my country. Because most of the control methods against Spodoptera frugiperda are mainly chemical methods, which cause different degrees of resistance to various insecticides and have obvious impact on the ecological environment, so it is imminent to seek a pollution-free and sustainable control method , ...
