Abstract
Methods of assaying insects for pesticide resistance and to identify insect species are based on feeding disruption caused by pesticides such as the biopesticide Bacillus thuringiensis toxin (Bt). The assay end-point is feeding disruption, measured by the fecal production of insects exposed to a diagnostic dose of pesticide in a test diet. Pesticide resistance can be assessed at the level of an individual insect or at population levels. Apparatus useful in such assays are described.
