The present invention concerns novel N-substituted (heteroaryl)alkyl sulfilimines and their use in controlling insects, particularly aphids and other sucking insects, as well as certain other invertebrates. This invention also includes new synthetic procedures for preparing the compounds, pesticide compositions containing the compounds, and methods of controlling insects using the compounds.
There is an acute need for new insecticides. Insects are developing resistance to the insecticides in current use. At least 400 species of arthropods are resistant to one or more insecticides. The development of resistance to some of the older insecticides, such as DDT, the carbamates, and the organophosphates, is well known. But resistance has even developed to some of the newer pyrethroid insecticides. Therefore a need exists for new insecticides, and particularly for compounds that have new or atypical modes of action.
