Problems solved by technology

At present, some researchers have studied the pheromone behavior regulators of desert locusts and African migratory locusts, and locust plagues occur every year in my country, and it is urgent to find methods that can replace chemical pesticides to control locusts. There are still few research reports on the methods and applications of controlling locusts, controlling locust behavior, and stimulating locusts to feed.

Embodiment 1

[0018] (1) Calculated on the basis of 100 parts by weight, weigh 12 parts of starch and 85 parts of sucrose and mix thoroughly to obtain a mixture of starch and sucrose.

[0019] (2) Mix 2-heptanone, trans-2-pentanal, 2-methyl-2-pentenal, and 2-octanone in a 1:1 ratio to obtain a mixture of chemical substances .

[0020] (3) Weigh 3 parts of the mixture of the above chemical substances, add the mixture of starch and sucrose, and stir thoroughly for 10 minutes to obtain a locust feeding stimulant.

Embodiment 2

[0022] Cover the filter paper evenly with the locust feeding stimulant, and then put it in ten petri dishes prepared in advance as the experimental group, and prepare ten petri dishes, put the filter paper not coated with the locust feeding stimulant as the control experimental group .

[0023] Put a locust in each petri dish, and determine the selection index of the locust biting and feeding stimulus by the biting response of the locust to the filter paper sheet, selection index=number of locust biting filter paper sheets / total number of petri dishes. The results showed that the selection index of locusts biting the filter paper coated with feeding stimulant was 0.56, while the selection index of biting the filter paper not coated with feeding stimulant was 0.22, and the difference between the two was extremely significant. It shows that the feeding stimulant can effectively stimulate locusts to feed ( image 3 ).

Abstract

The invention relates to a locust feeding stimulant as well as a preparation method and application thereof, belonging to the technical field of pest control. The invention aims to provide the locustfeeding stimulant as well as the preparation method and application thereof. The locust feeding stimulant is used for preventing and treating locusts, can control locust behaviors, stimulates locust feeding, and causes locust nymphs to generate a tropism biting feeding reaction on objects containing the locust feeding stimulant. During locust prevention and control, when the locust feeding stimulant is applied to pesticides and objects sprayed with the pesticides, the active contact of the locusts to the pesticides and pesticide intake probability can be increased, and the killing, preventingand controlling effects of the pesticide are better improved. During locust prevention and control, when the locust feeding stimulant is applied to a locust monitoring device and a locust killing device, the probability that the locusts actively make contact with the locust monitoring or killing device can be increased, so the locust monitoring device can monitor more locusts and has improved accuracy, the locust killing device can kill more locusts and has increased killing rate, and locust prevention, control 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 feeding stimulator and its preparation method and application. Background technique [0002] Locusts are major pests that seriously threaten my country's agricultural and animal husbandry production. At present, the method of controlling this pest is mainly chemical pesticide control. Although the large-scale use of chemical pesticides can effectively control locust infestation, it will also bring environmental pollution, excessive chemical pesticide residues in agricultural products, increased resistance of locusts, and increased control costs. Serious incidents such as human and animal poisoning often occur. Therefore adopting the method that can replace chemical pesticide to control locust infestation, so that realize the goal of sustainable development is present very urgent task. Insect behavior regulators, also known as pheromones, are generally compounds ob...
