Problems solved by technology

[0004] Field production generally adopts chemical control methods, which have quick results, but there are problems of pesticide residues
At the same time, the food safety and taste of wheat are affected
In addition, long-term application of pesticides will also make wheat aphids resistant to pesticides, resulting in a decline in efficacy, making it more difficult for future control

Embodiment 1

[0020] Example 1 Preparation of hoverfly trapping composition

[0021] Mix cis-cis-11-hexadecene acetate and plant volatiles in different proportions (the total amount is 1000 μg), dissolve in 1 mL of n-hexane, drop into 1 mL of anti-mouth rubber tip, and air-dry to obtain hoverfly Lure composition lure core.

[0022] Mix cis-11-hexadecene acetate and plant volatiles in different proportions (the total amount is 1000 μg), dissolve them in 1 mL of chlorinated paraffin, add them to a 1 mL polyethylene bottle, and seal them to obtain hoverfly lures. Set composition lures. The formulations of different hoverfly trapping compositions are shown in Table 1.

Embodiment 2

[0026] Example 2 Field test of hoverfly trapping composition (anti-mouth rubber lure core)

[0027] A wheat field with consistent growth, consistent management conditions, and large and neat plots was selected as the experimental field. To facilitate the monitoring of the lure effect, the lure core prepared in Example 1 was placed on the box-type trap, and the middle part of the box-type trap was placed to be flush with the top of the crop. To ensure the release effect, 100 ~1500 μg of hoverfly trapping composition, the average distance between traps is above 10m. Three replicates were set up for each treatment, arranged randomly, and the rubber carrier of n-hexane was used as the control. After setting, the number of lured hoverflies was investigated every two days, and the investigation continued for 30 days. The test results are shown in Table 1.

Embodiment 3

[0031] Example 3 Investigation of the growth and decline of aphids by the hoverfly trapping composition,

[0032] According to the occurrence dynamics of wheat aphids and their natural enemies, and experimental data such as wheat aphid control indicators (about 500 heads / hundred plants) and the best time to release natural enemies, field investigations are carried out on the basis of Example 2, and wheat flower end grouting is carried out. At the initial stage, hoverflies were used to trap and prey on wheat aphids, and a good control effect was obtained (see Table 3).

Abstract

The invention discloses a trapping composition for hoverflies and application thereof in the technical field of the preparation of insect sex pheromone. The trapping composition contains an insect pheromone and a plant volatile matter, wherein the insect pheromone is cis-11-hexadecene acetate, the plant volatile matter is one or more of ocimene, nerol and alpha-caryophyllene, and the weight ratioof the insect pheromone to the plant volatile matter is (50-100) to 1. The trapping composition provided by the invention is easy to prepare, and raw materials are easily available; the composition has very strong trapping capacity, good stability and long lasting period, and the prevention and treatment effects last for 30 days or above; the specifity is strong, and the resistance of the hoverflies cannot be generated; the trapping composition is harmless to human and livestock and environment-friendly; and the trapping composition is strong in stress resistance and convenient to use. The trapping composition can be used for controlling pest situations of hoverflies and trapping a large amount of the hoverflies to capture cereal aphids and has very important significance to the comprehensive treatment of the cereal aphids.

Description

technical field [0001] The invention belongs to the technical field of insect sex pheromone preparation, and in particular relates to a hoverfly trapping composition and application thereof. Background technique [0002] Wheat is the second largest food crop in my country, second only to rice in terms of area and output. Wheat aphid is a major pest in wheat production, and its occurrence area is on the rise. Wheat aphid affects photosynthesis, nutrient absorption and conduction of wheat. It overwinters in wheat and rice piles, and clusters to suck juice from wheat leaves, stems and spikes during the nymph and adult stages. The peak period of wheat aphid damage is from the earing to grain filling stage of wheat. During the earing period, wheat aphids concentrate on the wheat ears and suck the wheat, which makes the wheat grains empty and the wheat yield decreases. Since the 1990s, the annual occurrence area of ​​wheat aphids has increased rapidly, from 3.42 million ha in 19...
