Embodiment Construction

[0014] Specific embodiments of the present invention are described in detail below, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0015] Laboratory conditions: All experiments in this study were conducted in Jiangsu Provincial Key Laboratory of Medicinal Plant Biotechnology. The experimental department has an engineering technology center with a large number of advanced reaction instruments and testing equipment, which provides a good hardware foundation for scientific research and has the conditions to carry out indoor experiments on killing apple snails.

[0016] 1. Experimental materials

[0017] Biological materials: Apple snails were provided by Xuzhou Knott Company. Individuals with 5-7 spins of apple snails with high vitality were selected indoors. 800-1000 apple snails were used for each round of experiments, and 3 experiments were repeated.

[0018] Experimental medicament: The experimenta...

Abstract

The invention discloses a biopesticide oncomelania killing drug which is composed of the following raw materials in percentage by weight: 4% of metaldehyde powder, 12-20% of oil-tea-cake powder, 8% of gypsum powder, 1% of an attractant and 73-78% of flour. According to the biopesticide oncomelania killing drug disclosed by the invention, tea saponin is compounded with metaldehyde, the usage amount of the metaldehyde is reduced from 6% to 4%, the content of the metaldehyde in the pesticide is effectively reduced, and the field dosage is reduced; the problem that diseases even cancers are possibly caused due to long-term contact with the pesticide, and genetic mechanisms of living organisms are possibly injured in severe cases so as to cause gene mutation can be solved. The potential hazard of the metaldehyde on the environment and human bodies can be reduced; and the drug effect is obvious, and the dosage cost is reduced.

Description

Technical field: [0001] The invention belongs to the technical field of biochemistry, and in particular relates to a biological pesticide molluscicide and a preparation method of the molluscicide. Background technique: [0002] Metaldehyde, also known as Mida, Miscarling, and Snail Di, is a white needle-like crystal, which cannot be hydrolyzed or photolyzed. Metaldehyde is a special-effect pesticide for molluscs, which traps and kills apple snails with its strong selectivity. Metaldehyde replaces traditional highly toxic chemical pesticides and plays an important role in the prevention and control of mollusk disasters such as apple snails. However, metaldehyde is still a toxic chemical agent, and long-term exposure can still have adverse effects on the human body. [0003] Apple snails are also known as snow snails and apple snails. Adults generally have 5-6 spins and are relatively large in size, with a maximum shell diameter of 15cm. They are highly destructive to fruits...
