Compound causing muscle spasms in insects

Abstract

The invention provides a compound causing muscle spasms in insects, and belongs to the technical field of biology. The compound comprises an active insecticidal compound causing muscle spasms and death in insects, a copper-based bactericidal ingredient with gastric toxicity, an attractant containing vegetable hydrolyzed protein or animal hydrolyzed protein or higher fatty acids or sugar as well asa starch-based coating material. A preparation method of the compound comprises following steps: the copper-based insecticidal ingredient is dispersed in the protective starch-based coating material,a dispersoid formed after drying is mixed with the active insecticidal compound and the attractant, and a dispersed phase compound is prepared. The compound has no cross resistance to the existing insecticides, is not prone to agglomeration, has better fluidity, suspension and efficacy persistence, performs abnormal interference on insect nervous systems, and causes muscle spasms paralyzing insects to death. The preparation method can reduce molecular crystallization properties, improve coating mechanical properties, tensile strength and barrier properties, and prolong drug activity and shelflife.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a compound for causing muscle spasm in insects. Background technique [0002] Insect infection is a major threat to commercially important crops such as soybean and cotton, and the yield of plants is negatively affected by insect infestation. Chemical control is an important way to prevent and control pests in agriculture. However, existing agents are unsatisfactory effective against certain types of pests, being selective for invertebrates such as insects, arachnids and their larvae, and having little effect on vertebrates such as mammals, fish, poultry and others. Toxic or non-toxic, and have the disadvantages of residues and harm to the environment; toxic or have harmful effects on mammals, fish, poultry or other species that are not the target of the product, such as organophosphorus compounds and carbamates inhibit insects and all The activity of acetylcholinestera...

Problems solved by technology

However, existing agents are unsatisfactory effective against certain types of pests, being selective for invertebrates such as insects, arachnids and their larvae, and having little effect on vertebrates such as mammals, fish, poultry and others. Toxic or non-toxic, and have the disadvantages of residues and harm to the environment; toxic or have harmful effects on mammals, fish, poultry or other species that are not the target of the product, such as organophosphorus compounds and carbamates inhibit insects and all The activity of acetylcholinesterase in animal species, dimeform and related formamidines are known to act on octopamine receptors in insects, but due to potential cardiotoxicity to vertebrates and carcinogenicity to animals and to different insects various effects have been withdrawn from the market; although the alternate use of several insect inhibitors with different modes of action is suitable for good pest management, this method cannot control insects satisfactorily; the use of drugs is only in areas with high insect incidence Strip application, spot application, and soil application are used to avoid direct contact with natural enemies. The use of selective and non-permanent agents increases environmental safety and reduces the occurrence of insect resistance, but most of them can only be used in actual use. Control insect infestations individually to prevent cross-resistance in insects

In addition, due to the long-term use of conventional pesticides, many pests have developed resistance and resistance to commonly used pesticides, and the current environmental and economic requirements for the use of insecticides (such as spectrum of action, toxicity, selectivity, application rate, residual Formation of substances and good preparation ability) are increasing
