Ion channels remain the primary target of most of the small molecule
insecticides. This review examines how the subunit composition of heterologously
expressed receptors determines their insecticide-specific pharmacology and how
the pharmacology of expressed receptors differs from those found in the insect
nervous system. We find that the insecticide-specific pharmacology of some
receptors, like that containing subunits of the Rdl encoded GABA receptor, can be
reconstituted with very few of the naturally occurring subunits expressed. In
contrast, workers have struggled even to express functional insect nicotinic
acetylcholine receptors (nAChRs), and work has therefore often relied upon the
expression of vertebrate receptor subunits in their place. We also examine the
extent to which insecticide-resistance-associated mutations, such as those in the
para encoded voltage-gated sodium channel, can reveal details of
insecticide-binding sites and mode of action. In particular, we examine whether
mutations are present in the insecticide-binding site and/or at sites that
allosterically affect the drug preferred conformation of the receptor. We also
discuss the ryanodine receptor as a target for the recently developed diamides.
Finally, we examine the lethality of the genes encoding these receptor subunits
and discuss how this might determine the degree of conservation of the
resistance-associated mutations found.
