Embodiment 1

[0021] Food attractant formula 1: 2 grams of linalool, 2 grams of citric acid, 1.5 grams of β-caryophyllene, and 1.5 grams of cis-phylloyl acetate, mixed evenly to obtain formula 1.

[0022] Food attractant formula 2: 4 grams of linalool, 4 grams of citric acid, 3 grams of β-caryophyllene, and 3 grams of cis-phylloyl acetate, mixed evenly to obtain formula 2.

Embodiment 2

[0024] Sex lure formula 1: 1 gram of (cis, trans)-9,12-tetradecadienol acetate and 1 gram of (cis)-9-tetradecenol, mixed uniformly to obtain sex lure formula 1.

[0025] Sex lure formula 2: 1.5 g of (cis, trans)-9,12-tetradecadienol acetate and 1.5 g of (cis)-9-tetradecenol, mixed uniformly to obtain sex lure formula 2.

Embodiment 3

[0027] Food attractant and sex attractant joint formula 1: 2 grams of linalool, 2 grams of citric acid, 1.5 grams of β-caryophyllene, 1.5 grams of cis-phyllyl acetate, (cis, trans)-9,12-tetradecyl 1 gram of dienyl acetate and 1 gram of (cis)-9-tetradecenol were mixed uniformly to obtain joint formula 1 of food attractant and sex attractant.

[0028] Put food attractant and sex attractant joint formula 1, food attractant formula 1 and sex attractant formula 1 into the trap respectively, arrange them in an equilateral triangle, and the hanging time and hanging height are the same. According to the statistics of the target pest beet armyworm caught every day, 1616 traps were caught by the food attractant and sex attractant formula 1 trap, 398 were caught by the sex attractant formula 1 trap, and 735 were caught by the food attractant formula 1 trap Head, the trapping effect of joint formula 1 is 35.46% higher than the sum of trapping alone.

Abstract

The invention discloses a composition for preventing and treating spodoptera exigua Hubner and application thereof, and belongs to the technical field of biological control of crop pests. The composition for preventing and treating the spodoptera exigua Hubner is composed of a food attractant and a sex attractant according to the mass ratio of 7:1-3, wherein the effective components of the food attractant are linalool, citric acid, beta caryophyllene and cis-3-hexenyl acetate; and the effective components of the sex attractant are (Z,E)-9,12-Tetradecadien-1-ol acetate and (Z)-9-Tetradecenyl acetate. The food attractant and the sex attractant are combined to cooperatively prevent and control the beet armyworms in a soybean field, so that the environment pollution caused by pesticide is avoided, the prevention and control effect is ideal, the harm of the beet armyworms to soybeans is reduced, and the economic benefit and the ecological benefit are obvious.

Description

technical field [0001] The invention belongs to the technical field of biological control of crop pests, and in particular relates to a composition and application for controlling beet armyworm. Background technique [0002] Beet armyworm (Spodoptera exigua Hübner) belongs to Lepidoptera and Noctuidae. It is a worldwide obstinate pest. The insect has many generations, miscellaneous feeding habits and rapid reproduction, and it does serious damage. There are more than 100 species of host plants. In addition to small miscellaneous grains such as soybeans and corn, he also likes to eat a variety of vegetables and Chinese herbal medicines. The soybeans harmed by the beet armyworm generally lose 20% to 30% of their yield, and the maximum can reach more than 80%, which seriously affects the healthy development of the soybean industry. [0003] In recent years, due to the impact of trade barriers, the domestic demand for soybeans has been increasing, resulting in an increase in th...
