Abstract

The invention relates to the technical field of plant control, and discloses an agent for inhibiting the eclosion of mosquito larvae. The agent of the present invention include radix lithospermi, 2,3-dimethylhydroquinone and lithospermic acid, and the balance being water. In the present invention, radix lithospermi, 2,3-dimethylhydroquinone and lithospermic acid are selected as the effective components of the agent. By spraying the agent and controlling the mosquito larvae, the number of eclosion of mosquito larvae can be significantly reduced.

Description

technical field [0001] The invention relates to the technical field of plant control, in particular to a reagent for inhibiting the emergence of mosquito larvae and its application. Background technique [0002] Mosquitoes are one of the four pests, and their average lifespan is not long. Males are 3 to 10 days, and females are 10 to 20 days. They belong to the family Diptera, Insecta, and there are about 3,000 species in the world. Among them, Anopheles, Aedes and Culex are the most famous, among which Culex is our common house mosquito. [0003] Mosquitoes are tiny flying insects with sucking mouthparts. Usually females feed on blood, while males suck on plant sap. Mosquitoes have their own anti-virus organs and cannot transmit viruses through bites. The blood-sucking female mosquitoes are the intermediate hosts of other pathogens such as dengue fever, malaria, yellow fever, filariasis, and Japanese encephalitis. Therefore, mosquito control has always been a more import...
