Zusammenfassung:The invention provides insecticidal compositions exhibiting excellent knockdown activity against public health pests, in particular cockroach species, comprising compounds of formula (I) : wherein X represents a group of formula : where (i) R and R are each selected from hydrogen, halo and C1-4 alkyl, or (ii) R is hydrogen and R represents either R (R )C=CH- or R (R )(R )C-CH(R )-, where R and R are selected from hydrogen, methyl, halo and C1-2 haloalkyl and R is selected from chloro and bromo. The invention also provides methods of use of the compositions, novel compounds of formula (I) and processes for their preparation.
