Description

Detention spraying insecticidal composition and application thereof Technical Field The invention relates to a sanitary insecticide, in particular to a detention spraying insecticidal composition and application thereof. Background The 4-trifluoromethyl nicotinamide is a metabolite of flonicamid and has insecticidal activity. 4-trifluoromethyl nicotinamide can bind to and inhibit the activity of nicotinamide enzymes in insects. Nicotinamide enzyme is expressed in the spinal cord tension receptor neurons/chordae neurons and is also the 9 th molecular target in the insect nervous system. Inhibition of nicotinamide enzyme by 4-trifluoromethyl nicotinamide results in accumulation of the substrate nicotinamide, thereby overactivating TRPV ion channels resulting in toxic symptoms. In the current external environment field retention spraying products, pyrethroid insecticide products are more, and the large-scale use of pyrethroid insecticide or the long-term use of single product can possibly cause the large drug resistance of insects such as mosquitoes, flies, cockroaches and the like, and the phenomenon of general reduction of the prevention effect occurs in recent years. Therefore, an environment-friendly and efficient pesticide compound variety is needed at present to delay the generation of drug resistance of sanitary pests. The current mixing of different pesticides is a common method for delaying the generation of resistance, and reasonable formulas are obtained through formula screening, so that the dosage can be effectively reduced, the cost is reduced, and the generation of the drug resistance of pests is delayed. However, the blending property should be further investigated.
