Abstract

The invention belongs to the technical field of pesticide compound, and concretely provides a composition used for controlling liriomyza sativae. The effective components of the composition are theta-cypermethrin and spinosad, and the weight ratio of spinosad to theta-cypermethrin is 1:1-10:1. The compound combination resists generation of drug resistance of insects effectively, the problem of existing drug resistance of insects is solved at the greatest extent, and therefore the pesticide dosage is decreased, the influence to the environment is reduced, and the composition can be applied to nuisanceless crops.

Description

technical field [0001] The invention belongs to the technical field of compounding pesticides and insecticides, in particular to a composition for preventing and controlling Liriomyza sativae. Background technique [0002] Liriomyza sativae [0003] Liriomyza sativae, the adult body is small, the head is yellow, the back of the eyes is black; the mesothoracic back plate is black and bright, and the mesothoracic side plate is mostly yellow; the legs are yellow; the eggs are white and translucent; Translucent, then bright orange-yellow; pupae oval, orange-yellow, 1.3-2.3mm long. [0004] There were more than 110 species of host plants, among which Cucurbitaceae, Solanaceae and Leguminosae suffered the most. Its damage rate to leaves can reach 10% to 80%, often resulting in reduced production and quality of melons and vegetables, and even failure in serious cases. This species is difficult to find. There are many species of Liriomyza sativae in my country. Because their bod...
