Abstract

The present invention provides a compound botanical insecticide for mosquito larvae control, a preparation method therefor and applications thereof. The insecticide consists of a bulk drug and conventional auxiliaries, wherein the mass of the bulk drug is 40-80% of the mass of the insecticide, and the mass of the conventional auxiliaries is 20-60% of the mass of the insecticide. The bulk drug comprises the following components in weight percentages based on the total weight of the bulk drug: 2-20% of a tomato extract, 5-30% of a garlic extract, 5-30% of a Euphorbia humifusa extract, 5-10% of a ginger extract, 5-25% of a potato extract, 5-30% of a Cinnamomum camphora extract, 5-20% of a photinia extract, 5-15% of a Liriodendron chinense extract, and 4-10% of a Camptotheca acuminata extract. The compound botanical insecticide for mosquito larvae control provided by the present invention is high in efficiency, free of residuals, low in production cost, economical and practical, environmentally-friendly, and excellent in comprehensive properties, and comprises agricultural wastes.

Description

technical field [0001] The invention relates to a plant insecticide for killing mosquito larvae in the technical field of biological control of hygienic insect pests, in particular to a compound plant insecticide using waste plant resources for killing mosquito larvae and its preparation and application . Background technique [0002] Mosquitoes are tiny flying insects with piercing-sucking mouthparts and are one of the four pests. The deadliest animal in the world ranks NO.1 mosquito, which kills more than 725,000 people every year. Usually the females feed on blood, while the males drink the sap of plants. Mosquitoes have their own anti-virus organs and cannot transmit viruses through bites. Blood-sucking female mosquitoes are intermediate hosts for other pathogens such as dengue fever, malaria, yellow fever, filariasis, and Japanese encephalitis. [0003] At present, the main components of mosquito killers on the market are pyrethroids, such as tetramethrin, permethrin...
