Abstract: The present invention is in the field of identification and characterization of novel insecticidal target sites and, in particular, relates to host cells, assays and antibodies thereto.

Abstract: The present invention relates to the use of substituted aryl- and heteroarylpropargylamines of the formula (I) where a) R1 is heteroaryl or aryl, unsubstituted or mono- or polysubstituted by identical or different radicals, b) A is a group CR4R5 or C?O, where R4 is hydrogen, halogen or alkyl; R5 is hydrogen, halogen or a substituted or unsubstituted hydrocarbon radical; c) R2 and R3 together with the nitrogen atom to which they are attached form N-heteroaryl or N-heterocyclyl, unsubstituted or mono- or polysubstituted by identical or different radicals, if appropriate also as N-oxide or salt, as pesticide against arthropods and helminths for protecting plants and animals.
