Insecticidal synergistic composition for mosquitoes and flies

Abstract

The invention relates to an insecticidal synergistic composition, in particular to the insecticidal synergistic composition for mosquitoes and flies, and belongs to the technical field of compositions. The insecticidal synergistic composition for the mosquitoes and flies has active components of pyriproxyfen and organophosphorus, wherein the weight ratio of the pyriproxyfen to the organophosphorus is 30:1-1:45; and the organophosphorus is abathion or tiguron. The difference of a medicament prepared from the composition from conventional white ant killing medicaments lies in that: the pyriproxyfen and the abathion or tiguron are taken as the active components, through the synergism of double function mechanisms generated by the pyriproxyfen and the abathion or tiguron, the insecticidal synergistic composition can act on nervous systems of the larva of the mosquitoes and flies, inhibit pupation and eclosion of the larva of the mosquitoes and flies, and improve the activity of killing the larva and pupa of the mosquitoes and flies, has obvious synergism, can kill the larva of the mosquitoes and flies in short time, and can ensure the persistent effect for a long time.

Description

technical field [0001] The invention relates to an insecticidal synergistic composition, in particular to an insecticidal synergistic composition for mosquitoes and flies, and belongs to the technical field of compositions. Background technique [0002] Mosquitoes belong to the insect class Diptera, and there are about 3,300 species in the world. It is a tiny flying insect with piercing-sucking mouthparts. Mosquitoes are insects that undergo complete metamorphosis, and their life cycle can be divided into four stages: egg, larva, pupa, and adult. Usually the females feed on blood, while the males drink the sap of plants. Mosquitoes are found on every continent except Antarctica. Among them, Anopheles, Aedes, and Culex are the most famous. The main hazard of mosquitoes is the transmission of diseases, followed by biting, which causes discomfort to people. According to research, there are more than 80 kinds of diseases transmitted by mosquitoes. No animal on earth is mor...

Problems solved by technology

[0004] Pyriproxyfen and organophosphorus have different mechanisms of action. Although they are widely used in the control of mosquitoes, fly larvae and pupae, the quick-acting properties of pyriproxyfen and organophosphorus are poor, and they The mechanism of action of each is single, and it is easy to produce drug resistance, which leads to the reduction of the effect of killing mosquitoes and flies. The quick-acting and long-lasting effects cannot be combined, and the cost of use increases, causing great hidden dangers to people's living environment.
