CN-121986780-A - Application of n-pentadecane in preparation of cockroach control product

Abstract

The invention belongs to the technical field of green prevention and control of pests, and particularly relates to application of n-pentadecane in preparation of cockroach control products. The structure of n-pentadecane is shown below. The invention provides a sustainable cockroach control strategy. The natural chemical n-pentadecane volatilized from the body surface of the spider is used as a lure agent, so that cockroaches can be effectively prevented, excessive use of chemicals can be avoided, and negative influence on ecological environment is reduced. 。

Description

Application of n-pentadecane in preparation of cockroach control product Technical Field The invention belongs to the technical field of green prevention and control of pests, and particularly relates to application of n-pentadecane in preparation of cockroach control products. Background Cockroaches (e.g., cherry red cockroaches) are widely used as important hygienic pests in homes, restaurants, food processing plants, etc., transmitting pathogens, contaminating food, and causing allergic reactions. The control of which has been dependent on chemical pesticides, such as the most commercially available pesticides containing cypermethrin, prathrin, bifenthrin components. However, there is an increasing problem of resistance to drugs for long-term use of existing chemical pesticides in large quantities. Disclosure of Invention In order to solve the problem that the existing chemical pesticides are increasingly serious in drug resistance after being used for a large amount for a long time in the prior art, the invention aims to develop a novel cockroach control strategy, and the invention provides application of n-pentadecane in preparation of cockroach control products. In order to achieve the above purpose, the present invention adopts the following technical scheme. The invention provides an application of n-pentadecane in preparing cockroach control products, wherein the structure of the n-pentadecane is as follows: 。 further, the cockroach control product takes n-pentadecane as an active ingredient and is assisted with an agropharmaceutically acceptable carrier. Further, the n-pentadecane accounts for 10% -50% of the total mass of the n-pentadecane and the carrier. Further, the cockroach control product is selected from any one of spray, gel, slow release particles and smearing agent. Further, when the cockroach control product is a spray, the carrier is selected from any one or more of water, an organic solvent, and a surfactant. When the cockroach control product is a gel, the carrier is selected from any one or more of carbomers, xanthan gum, cellulose derivatives and polyols. When the cockroach control product is a slow release granule, the carrier is selected from any one or more of diatomite, bentonite, starch and saccharides. When the cockroach control product is a coating agent, the carrier is selected from any one or more of mineral oil, vegetable oil, paraffin and vaseline. Further, the mass percentage concentration of the n-pentadecane in the cockroach control product is 40% -50%. Further, the n-pentadecane is extracted from the body surface of the white giant crab spider. Further, the cockroach control product is used for repelling cockroaches. Further, the cockroach control product is used in a spraying mode. Further, the cockroaches include at least one of the following varieties: Cherry red cockroach, american cockroach, german cockroach, and oriental cockroach (Blatta orientalis). Compared with the prior art, the invention has the following beneficial effects: 1. The invention aims to develop a novel cockroach control strategy, and provides a novel, environment-friendly and efficient cockroach control strategy by innovatively extracting and screening n-pentadecane (n-pentadecane) which is a chemical substance with remarkable repellent effect from the body surface of the white giant crab spider, and finding that the n-pentadecane can remarkably induce the repellent behavior of cockroaches, namely provides application of the n-pentadecane in preparation of cockroach control products. The invention adopts n-pentadecane as an active ingredient, and fundamentally avoids the drug resistance mechanism of the traditional chemical pesticide. Traditional chemical pesticides are mostly nerve agents, and act on specific molecular targets such as acetylcholine receptors, sodium ion channels and the like to play a role in killing insects, so that cockroaches are easy to generate resistance through target site mutation or over-expression of metabolic enzymes under continuous selection pressure. N-pentadecane is used as saturated alkane, the action mode is not based on the poisoning effect of specific molecular targets, but the repellent or lethal effect is realized through physical actions (such as dissolving or destroying a waxy layer on the surface of the cockroach, blocking pores or interfering with chemical communication), the action mechanism lacks specific protein targets which can be mutated, and the cockroaches are difficult to evolve an enzyme system which can efficiently metabolize long-chain alkane. Therefore, the cockroach population cannot generate adaptive resistance to the n-pentadecane through the traditional resistance evolution path, so that the problem of increasingly serious drug resistance of chemical pesticides is effectively solved. 2. The invention adopts the chemical substance n-pentadecane of natural source, avoids the toxicity and environmental pollution of chemical pesticides,
