Embodiment 1

[0016] Example 1 : Attractive effect of attractant composition on Spodoptera litura

[0017] Test method: The insect inlet of the trap is 1.5m from the ground, and the distance between the traps is about 20m. The trapping experiment lasted for 5 days, and 10 traps were set for each treatment (that is, repeated 10 times in the same experiment), with a total of 6 plots.

[0018] Table 1 Test drug formulation

[0019]

[0020]

[0021] The attractant composition of table 2 is to the attracting effect of Spodoptera litura

[0022]

[0023] It can be seen from Table 1-2 that the odor attractant phenylacetaldehyde has a good strengthening effect on the sex attractant, and different odor attractant combinations have certain differences in the attracting effect on the sex attractant. The combination of odor compounds cis-3-hexene acetate, phenylacetaldehyde and limonene in formula H3 can better enhance the attractant effect of the sex attractant.

Embodiment 2

[0024] Example 2 : Optimum ratio screening of odor compounds

[0025] Test method: The insect inlet of the trap is 1.5m from the ground, and the distance between the traps is about 20m. The trapping experiment lasted for 5 days, and 10 traps were set for each treatment (that is, repeated 10 times in the same experiment), with a total of 6 plots.

[0026] Table 3 Odor compound optimal ratio screening formula

[0027]

[0028]

[0029] Table 4 Attractive effect of different combinations of odor compounds on Spodoptera litura

[0030]

[0031] As can be seen from Table 3-4, the combination of odor compounds cis-3-hexene acetate, phenylacetaldehyde and limonene in different proportions has certain differences in the attracting effect of the sex attractant. Preferably, phenylacetaldehyde, cis - The ratio of 3-hexene acetate to limonene is 2:1:1.

Embodiment 3

[0032] Example 3 : Optimum ratio screening of sex attractant formula

[0033] Test method: The insect inlet of the trap is 1.5m from the ground, and the distance between the traps is about 20m. The trapping experiment lasted for 5 days, and 10 traps were set for each treatment (that is, repeated 10 times in the same experiment), with a total of 6 plots.

[0034] Table 5 Sex attractant ratio screening formula

[0035]

[0036]

[0037] Table 6 Attractive effect of different proportioning attractant combinations on Spodoptera litura

[0038]

[0039] It can be seen from Table 5-6 that the attractant formulas of different ratios have little difference in attracting effect on Spodoptera litura, and the combination of 9Z, 11E-tetradecadienyl acetate and 9Z, 12E-tetradecadienyl acetate is preferred. The ratio is 9.5:1.

Abstract

The invention belongs to the agricultural field and in particular relates to a prodenia litura attractant composition. The prodenia litura attractant composition comprises a sex attractant, a smell compound, an antioxidant and a slow release carrier. The sex attractant is composed of 9Z, 11E-tetradecyl acetate and 9Z, 12E-tetradecyl acetate; the smell compound is composed of phenylacetaldehyde, cis-3-hexenyl acetate and limonene. The prodenia litura attractant composition has a very good induction effect to prodenia litura and can be used for preventing and treating the injurious insect prodenia litura. In addition, the smell compound screened has very good enhancing action to the sex attractant, and in particular, the preferred smell compound comprises phenylacetaldehyde, cis-3-hexenyl acetate and limonene in a ratio of 2: 1: 1.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to an attractant composition for Spodoptera litura and its application. Background technique [0002] Spodoptera litura is one of the main pests that harm vegetables. It has the characteristics of long-term damage, wide feeding habits, and great harm, and it is easy to break out and cause disasters. At present, chemical control is the main measure to control Spodoptera litura in vegetable production. However, in the process of vegetable production, due to excessive reliance and frequent use of high-concentration chemical agents to control pests and diseases, not only the resistance of pests is significantly enhanced, but also the pesticide residues in vegetable products exceed the standard, seriously affecting vegetable quality and food safety. How to effectively resolve these problems and effectively curb the harm of Spodoptera litura has become a major constraint factor in ...
