Description
Technical Field
The invention relates to the technical field of phagostimulants, in particular to a phagostimulant for migratory locusts and a preparation method thereof.
Background
Migratory locusts are a kind of serious devastating disaster in agriculture and grassland. The existing method for preventing and controlling the pests is mainly chemical pesticide control, and although locust can be effectively controlled by using a large amount of chemical pesticide, adverse effects such as environmental pollution, overproof chemical pesticide residue of agricultural products, increased locust drug resistance, increased control cost, severe cases frequently causing poisoning of people and livestock and the like can be brought. Therefore, the adoption of a control method which can replace chemical pesticides so as to achieve the aim of sustainable development is a very urgent task at present. Insect behavior modifiers, also known as pheromones, are generally compounds obtained from the natural environment that modulate insect behavior and are therefore degradable in nature. And the insects are extremely sensitive to pheromones, so the use amount is low generally, the environment and agricultural products are not easy to be polluted, the pests are not easy to generate drug resistance, and the pesticide is nontoxic to people and livestock. Is widely considered to have wide prospect in the field of pest control in the world. The pheromone behavior regulator of the desert locusts has been studied.
Since migratory locusts are not the same species as desert locusts, the pheromone of migratory locusts described herein is clearly different from desert locusts. Migratory locusts are major pests seriously threatening the production of agriculture and animal husbandry in China, the existing method for preventing and controlling the pests is mainly chemical pesticide, and no report is provided for the attractant of the pests.
