Problems solved by technology

At present, chemical pesticides are mainly used to prevent and control silver spider moths, but because chemical pesticides have brought huge pollution to humans and the environment, and the excessive use of chemical pesticides can easily make silver spider mites develop resistance, so humans have gradually changed chemical control to Biological control, exploring ways of sustainable control

Embodiment 1

[0011] The preparation of embodiment 1 silver ingot moth sex pheromone

[0012] Add the dichloromethane solution containing the pheromone of the silver moth armyworm dropwise on the lure core, after the dichloromethane solution containing the silver moth armyworm pheromone volatilizes, add n-hexane dropwise on the lure core, and wait for the n-hexane volatilization A lure wick containing the lure of silver-spotted moth is prepared, the lure is placed in a barrel-shaped trap, and then the trap is placed on a field where the occurrence of silver-spotted moth is serious. In order to ensure the release effect, 50-1000 μg of silver moth sex pheromone was placed in each 1mL rubber lure, the average distance between the traps was 10m, and the height of the traps was set at 30cm, 90cm, 150cm, and 210cm from the ground, respectively. In order to further illustrate the feasibility of the present embodiment, 10 specific formulas are provided in table 1:

Abstract

The invention discloses a sex pheromone for controlling macdunncughna crasssisigna warren. Macdunncughna crasssisigna warren pheromones comprise one or a plurality of types of cis-11-hexadecene acetate, cis-9-trans-12-tetradecene acetate and hexadecene acetate, and a mass ratio of the macdunncughna crasssisigna warren pheromones is 1.0-3.6:0.75-2:0.5-1.2. The sex pheromone has the advantages thatthe sex pheromone is low in dosage, is environmentally friendly and can be accurately applied to insect pest situation forecasting, mass trapping and mating disruption; effects of comprehensively managing the macdunncughna crasssisigna warren can be obviously improved, and accordingly the sex pheromone has important significance in comprehensively managing the macdunncughna crasssisigna warren.

Description

technical field [0001] The invention belongs to the technical field of preparation of insect sex pheromones, and in particular relates to a sex pheromone used for preventing and treating silver moths. Background technique [0002] Macdunnoughia crassisigna Warren, belonging to Lepidoptera, Noctuidae, is a leaf-eating pest. It mainly damages soybeans and cruciferous vegetables such as cabbage, lettuce, green peppers, eggplants, beans, carrots, chrysanthemums, etc. It is one of the important agricultural pests in my country. At present, chemical pesticides are mainly used to prevent and control silver spider moths, but because chemical pesticides have brought huge pollution to humans and the environment, and the excessive use of chemical pesticides can easily make silver spider mites develop resistance, so humans have gradually changed chemical control to Biological control, exploring ways of sustainable control. Insect pheromones come from insects, which will not cause harm...
