Problems solved by technology

[0006] The purpose of the present invention is to provide a practical and efficient plant volatile-based attractant for fall armyworm adults in order to overcome the existing technical problems that the control of fall armyworm is difficult and ineffective. The moth attractant composition has a good attracting effect on the fall armyworm, improves the male moth trapping rate, and can attract a certain number of female insects, and can be used for the monitoring and control of the fall armyworm

Embodiment 1

[0028] This embodiment studies the influence of the plant volatile odor compound component formula on the trapping effect, weighs each raw material according to the amount in Table 1, and then mixes cis-9-tetradecyl acetate and cis-7-dodecyl acetate Mixed, dissolved in n-hexane, configured into a solution, added to the silicone rubber lure, the solution was immersed in the silicone rubber lure, after the n-hexane was completely volatilized, cis-9-tetradecyl acetate and cis-7-deca The dicarbonyl acetate is adsorbed inside the lure of the silicone rubber head, and the lure of the silicone rubber head is stored at low temperature for subsequent use.

[0029] The plant volatile odor compound adopts PE bottle lures. After mixing the components, dissolve them in vegetable oil, add them to the PE bottle lures for heat sealing, and make plant volatiles lures. The lure core is placed in the barrel trap at the same time. The trap is 1.5 meters away from the ground, and the distance betw...

Embodiment 2

[0038] With reference to the method in Example 1, the difference is that the amount of raw materials used in Table 3 is used to study the impact of the volume ratio of plant volatile odor compounds on the trapping effect, wherein cis-9-tetradecyl acetate and cis-7-dodecyl The mass ratio of carbon acetate is 30:1.

[0039] Table 3 Amounts used for ratio screening of plant volatile odor compounds

[0040]

[0041] The trapping effects of different plant volatile odor compound ratios are shown in Table 4, from which it can be seen that the best ratio of phenylacetaldehyde, linalool and limonene three odor compounds is 1:2:1, followed by 1: 3:1. The difference in proportioning is reflected in the difference in concentration and speed of odor transmission released after mixing, so it has an impact on the trapping effect, which further illustrates that the three odor compounds of phenylacetaldehyde, linalool and limonene in the present invention interfere with each other when th...

Embodiment 3

[0045] Referring to the method in Example 1, the difference lies in the amount of each raw material in Table 5, and the influence of the mass ratio of the research attractant on the trapping effect.

[0046] Table 5 Scale for sex attractant ratio screening

[0047]

[0048] The trapping effects of different sex attractant ratios are shown in Table 6, from which it can be seen that the optimal mass ratio of sex attractant cis-9-tetradecyl acetate and cis-7-dodecyl acetate is 30 :1, followed by 100:3. Wherein, the C3 test group: 9.3 males of Spodoptera frugiperda were caught on average in 15 days, and the total number of females was 19, and the trapping rate of females was higher than that of males.

Abstract

The invention relates to a grassland spodoptera litura adult attractant based on a plant volatile matter and a trapping device comprising the grassland spodoptera litura adult attractant. The grassland spodoptera litura adult attractant is composed of a sex attractant and the plant smell volatile matter. The sex attractant is prepared from cis-9-tetradecane acetate and cis-7-dodecane acetate; theplant smell volatile matter is one or more of ethyl benzoate, benzyl alcohol, methyl salicylate, benzaldehyde, phenylacetaldehyde, limonene, linalool and benzyl acetate. The adult attractant for the grassland spodoptera litura has a good attracting effect on the grassland spodoptera litura through synergistic interaction of the sex attractant and the plant smell volatile matter, can attract part of female insects, can be used for monitoring and large-area prevention and control of the grassland spodoptera litura, and has a good application prospect.

Description

technical field [0001] The invention relates to insect trapping technology, in particular to an attractant for fall armyworm and a trapping device containing the attractant. Background technique [0002] Spodoptera frugiperda (J.E.Smith) is native to tropical and subtropical regions of America and is a major migratory pest on corn and other food crops. On January 13, 2019, it was confirmed that the fall armyworm had invaded Yunnan Province of my country. Spodoptera frugiperda has the following prominent features: First, it has miscellaneous feeding habits. It has a wide range of host plants, including corn, rice, barley, cotton, peanut, sorghum and 353 species of plants in 76 families. The second is strong reproductive ability. Females can mate and lay eggs many times, and can lay 900-1000 eggs in a lifetime, up to 2000 eggs. The third is that migration spreads quickly. It can fly more than 150 km per night, and can fly to areas beyond 1500 km with the airflow. The fou...
