The present invention relates to nitro-containing heterocyclic or ring-opening nitrogenous compounds of formula (A), wherein R, R, R, R, R, Y, Z, and W are as defined in the specification. The present invention discloses the preparation and the uses of a novel insecticide. Said compound and the derivatives thereof have high insecticidal activity to farm insects including homoptera and lepidoptera pests, such as aphis, fulgorides, aleyrodids, leafhopper, commom thrips, cotton bollworm, cabbage caterpillar, cabbage moth, cotton leafworm, armyworn and so on. 

Nitrogenous heterocyclic compounds with insecticidal activity, and the preparation and use thereof

The present invention discloses nitromethylene derivatives and the uses thereof. These derivatives are obtained by adding ring structure onto the known nitromethylene compounds, by which both their stability for light and their liposolubility are increased. Furthermore, by using the substituents linked to ether bond, the steric orientation of the nitro group and the liposolubility of the compounds are controlled. The insecticidal activity tests show that the compounds and their derivatives of the invention display high efficiency on killing various destructive insects with piercing-sucking type or scratching type mouthparts, such as aphid, leafhopper, plant hopper, thrips and white fly.
