Problems solved by technology

However, a large number of chemical pesticides have made the yellow cutworm resistant, and the excessive use of chemical pesticides has caused people to worry about the safety of crops. Therefore, humans have gradually transformed chemical control into biological control and explored sustainable control methods.

Embodiment 1

[0011] The preparation of embodiment 1 yellow cutworm sex pheromone

[0012] Add the dichloromethane solution containing the yellow cutcher pheromone dropwise on the lure, and after the dichloromethane solution containing the yellow cutcher pheromone volatilizes, add n-hexane dropwise on the lure, and wait until the n-hexane volatilizes. A lure core containing the yellow cutworm lure is prepared, the lure core is placed in a barrel trap, and then the trap is placed in a field where the yellow cutworm occurs more seriously. In order to ensure the release effect, 10-1500 μg of yellow cutworm sex pheromone is placed in each 1mL rubber lure, the average distance between the traps is about 10m, and the height of the lures is set to be about 150cm from the ground. The types of traps include There are two types of barrel traps and boat traps. In order to further illustrate the feasibility of the present embodiment, 10 specific formulas are provided in table 1:

Abstract

The invention discloses a yellow cutworm sex pheromone and its application. The yellow cutworm pheromone component is one or more of cis-7-dodecene acetate, cis-9-tetradecenyl acetate and cis-9-hexadecenal, wherein, The mass ratio of the yellow cutworm pheromone is 1.0-4.0:0.05-0.2:0.01-0.1. The sexual attractant of the present invention is simple to prepare, and the raw materials are easy to obtain; it has strong trapping ability, good stability, and long duration; it has strong specificity and will not cause resistance to the yellow cutworm; it is harmless to humans and animals, and is environmentally friendly. Friendly; strong stress resistance, easy to use. The sex attractant of the yellow cutworm of the invention can be accurately applied to insect situation monitoring, interfering with mating, and large-scale trapping, and is of great significance for comprehensive control of the yellow cutworm.

Description

technical field [0001] The invention belongs to the technical field of insect sex pheromone preparation, and in particular relates to a yellow cutworm sex pheromone and its application. Background technique [0002] Yellow cutworm (Agrotis segeium Schiff.), belonging to Lepidoptera, Noctuidae, is an important agricultural migratory pest. Also known as soil silkworm, it is widely distributed in Eurasia and Africa, and is more harmful in the north of the Yangtze River in my country. It has a wide range of hosts and is addicted to more than 50 kinds of crops such as wheat, corn, cotton, sugar beet, and rice. The larvae mainly feed on the stem tissue near the ground of tender seedlings, often causing the death of the whole plant and the broken seedlings and lack of ridges. Adults are nocturnal, concealed, and phototaxis. They like sweet and sour liquid. Each female lays 300-600 eggs. The yellow cutworm produces 2-4 generations every year, and survives the winter as mature lar...
