  • Publication number: 20050143418
    Abstract: It has now been found that certain novel heterocyclic derivatives have provided unexpected insecticidal activity. These compounds are represented by formula (I): R Preferred are those compounds of formula (I) where R2 and R3 taken together is ?NCH(R6)CH(R7)N(R8)—, ?NC(R6)?C(R7)N(R8)—, or ?CHN?C(R7)N(R8)—, and tautomers thereof, and where R4 and R5 taken together is —C(R11)?C(R12)C(R13)?C(R14) 1 12, —, where R,R,R 6, R 7, R8, R I1, R R 13, R 14, and X are described. In addition, compositions comprising an insecticidally effective amount of at least one compound of formula (I), and optionally, an effective amount of at least one of a second compound, with at least one insecticidally compatible carrier are also disclosed; along with methods of controlling insects comprising applying said compositions to a locus where insects are present or are expected to be present.
