Biochemical resistance detection: an alternative to bioassay.
Insecticide resistance is an increasing problem in vector control programmes. Until recently, the usual means of detecting it has been by bioassay, requiring the use of relatively large numbers of insects and insecticide-impregnated test papers which may be difficult to prepare and store reproducibly. William Brogdon argues for the use of biochemical microplate assays which are cheaper and easier to use, permit up to 30 assays to be made on a single insect, and give more reproducible results.
