Embodiment 1

[0015] (1) Fully mix the three chemical substances of acetophenone, valeraldehyde and 1-heptanol in a ratio of 1:1:1 to obtain a mixture of chemical substances.

[0016] (2) Based on 100 parts by weight, 97 parts of mineral oil were weighed to obtain a mineral oil solvent.

[0017] (3) Weighing 3 parts of the above chemical substance mixture, adding mineral oil solvent, and stirring thoroughly for 10 minutes, a locust repellent can be obtained.

[0018] (4) Then put it into a container and seal it for use.

Embodiment 2

[0020] Drop the repellant on the filter paper strip, and then put it in the insect olfactory behavior instrument (T-shaped tube, choose the tube arm length of 3 meters) to measure the locust's tendency response. It was found that the index of locust selection at the end with repellent was 0.23, the selection index of locust selection at the control (only solvent) was 0.61, and the selection index of no selection was about 0.16. The difference was extremely significant. Explain that this repellent is to repel locusts at a long distance, and also has a stronger repelling effect when it is 1 meter away from the smell source ( figure 1 ).

[0021] Selection index = number of locusts at a certain end / total number of locusts × 100%

Abstract

The invention discloses a locust repellent and a preparation method and application thereof, which are used for preventing and treating locusts and can repel the locusts, control locust behaviors, drive the locusts to be far away and cause locust tropism reaction. Because the chemical compounds are derived from plants, the chemical compounds have no toxic effect on the environment and human, livestock and poultry, are safe to natural enemies, and belong to natural pesticides. The locust repellent is used in areas and crops needing locust prevention and treatment, so that locusts are far away from the areas, the active contact probability of the locusts to the prevention and treatment areas and the crops is reduced, the prevention and treatment effect is achieved, and the environment and the crops are protected. The locust moving and migrating direction can also be controlled, locust repellents are used in one or more areas to force locusts to actively move to a target area by avoidingthe areas, then the locusts can be killed or monitored in a centralized mode in the target area, the locust killing rate and monitoring rate are increased, and the locust preventing, controlling and forecasting effects are better improved.

Description

technical field [0001] The invention relates to the technical field of pest control, in particular to a locust repellent and a preparation and use method thereof. Background technique [0002] Locusts are major pests that seriously threaten my country's agricultural and animal husbandry production. Insect behavior regulators, also known as pheromones, are generally compounds obtained from the natural environment that can regulate insect behavior, and thus can be degraded in nature. Moreover, insects are extremely sensitive to pheromones, so the general usage is very low, so it is not easy to pollute the environment and agricultural products, and it is not easy to make pests resistant to pesticides, and it is non-toxic to humans and animals. It is widely believed that it has broad prospects in the field of pest control. Studies have been conducted on pheromone behavioral regulators of desert locusts and African migratory locusts. The annual locust plague in our country is ...
