Biological source insecticidal composition and applications thereof

Abstract

The invention provides a biological source insecticidal composition and applications thereof. According to the invention, Metarhizium spores and boric acid are used as main active components, and auxiliary agents such as trehalose, sorbitol and the like are added, such that the moisture evaporation loss is reduced, the activity of Metarhizium spores is improved, and the use period is prolonged; and creamy flavors and Blattella germanica exoskeleton powder rich in cockroach pheromone are adopted to induce cockroaches to eat, and extra sugar is not introduced as a phagostimulant, such that the possibility of mixed bacterial introducing is reduced while the induction range is expanded and the attraction effect is enhanced so as to substantially prolong the storage and use period and achieve good practical application value.

Description

technical field [0001] The invention belongs to the technical field of microorganism and pest control, and in particular relates to a biological source insecticidal composition and its application. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Among the cockroach-killing drugs, contact killers are the most widely used, including water, powder, oil, granule, gel bait and other types. At present, among the same type of biological compound cockroach-killing drugs, granules are in the majority. However, it is difficult to ensure the long-term survival of biologically active ingredients in granules, and long-term storage may easily cause the photolysis of hydrazone, making ...

Problems solved by technology

[0004] The inventor discovered a pathogenic fungus used for the biological control of cockroaches - Metarhizium anisopliae EB0732, and applied for a related patent and obtained authorization (CN201611044989.1). In order to further improve the control effect, the inventor further developed a compound biological Insecticide (CN201611044989.1), the insecticide uses Metarhizium anisopliae spores and boric acid as active ingredients. However, the inventor found in follow-up research that, as one of the active ingredients, Metarhizium anisopliae spores are often difficult to overcome long-term The problem of storage and rapid recovery makes the shelf life of the product extremely short, and the spores cannot be recovered in a short time after application, which in turn affects the cockroach killing effect of the product; the selection of insect attractants is often brown sugar, biscuits and other foods with high sugar content. It is easy to germinate a large number of miscellaneous bacteria in a short period of time, especially in the glue bait paste with high water content, which is very easy to rot, which seizes the survival resources of Metarhizium anisopliae spores, resulting in a large number of deaths, which seriously affects the insecticidal effect of the glue bait

And the product is granules, if it is used in small spaces such as residences and restaurants, it will hinder daily cleaning and easily cause hygienic dead ends

Moreover, this type of granule uses oil as a solvent, so it is difficult for the spores to contact oxygen after application, and then germinate quickly, which affects the effect of killing cockroaches
