Problems solved by technology

The Pythium can effectively kill the highly dense mosquito larvae, larvae, which are still in the aquatic stage, and can effectively cut off the way for mosquitoes to transmit diseases. However, its application in killing mosquitoes is still in its infancy. Mosquito killing can only be done under the condition of vigor, directly making Pythium into mosquito killing products, the vigor is poor, it is difficult to meet the needs of practical application, at present, there is no report to use the mosquito killing products prepared by this Pythium

Abstract

The invention discloses a mosquito-killing gel. The gel is prepared by taking Pythium sp.GY1938 mycelium as an active ingredient and adding auxiliary materials. The gel comprises the following components: 150-300g / L of Pythium sp.GY1938 mycelium and 0.5-2g / L of 1 / 8-1 / 2* common fungus culture medium and coagulating agent. The invention further discloses a preparation method of the mosquito-killing gel. The mosquito-killing gel disclosed by the invention has the advantages of remarkable mosquito-killing effect, high stability, long effective period and environment friendliness.

Description

technical field [0001] The invention relates to a mosquito-killing gel. Background technique [0002] Mosquitoes are Diptera insects, which can transmit malaria, filariasis, yellow fever and dengue fever and other mosquito-borne diseases, threatening human health. Their development is metamorphosis, and they need to go through eggs, larvae (larvae), pupae, and adults4 period. Compared with adults, mosquito larvae must live in water at a high density, so the aquatic stage is the most effective entry point for mass killing mosquitoes and controlling mosquito-borne diseases from the source. At present, the common methods of mosquito control are still traditional chemical pesticides, but chemical pesticides pollute the environment, disrupt the ecological balance, and cause insecticide resistance. Biological control is the use of natural enemies of pests or microorganisms that can cause diseases to pests to control or kill pests. It is highly specific to pests, non-toxic and h...
