  • Patent number: 7655665
    Abstract: 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.
