Abstract

The invention discloses an insecticidal composition comprising pyriproxyfen, the insecticidal composition comprises an active component A and an active component B, the active component A is selected from the pyriproxyfen, the active component B is selected from any one of the following compounds: methoxyfenozide, furan tebufenozide, tebufenozide and chlorine tebufenozide, and the weight ratio of the active components A to the active component B is 1: 80-60:1. The insecticidal composition has a synergistic effect on a plurality of insect pests damaging agricultural production, can reduce the pesticide dosage, reduce pesticide residues in crops, and reduce environmental pollution, is safe to human and livestock, and has good environment compatibility, and the insect pests have low tendency to produce resistance to the insecticidal composition.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a pyriproxyfen-containing insecticidal composition on crop pests. Background technique [0002] Pyriproxyfen chemical name: 4-phenoxyphenyl (RS)-2-(2-pyridyloxy)propyl ether. Pyriproxyfen is a juvenile hormone-type chitin synthesis inhibitor with strong ovicidal effect. Pyriproxyfen also has systemic transfer activity, affecting larvae hiding behind leaves. The inhibitory effect on insects is manifested in affecting insect metamorphosis and reproduction. Toxicological tests on Spodoptera litura show that the high concentration of pyriproxyfen in the hemolymph accelerates the secretion of sex hormones in the prothymus of insects; on the other hand, because pyriproxyfen can make insects lack the stimulating factors required for oviposition, Inhibit embryonic development and egg hatching, or generate eggs without viability, so as to effectively control and ach...
