Insecticide bioassay refers to any quantitative procedure used to determine the relationship between the amount (i.e., dose or concentration) of an insecticide administered and the magnitude of response in a living organism. If the toxic effect (e.g., death) indeed results from the action of an insecticide, there must be a positive correlation between an appropriate range of the insecticide dose administered and the magnitude of the effect. Such a relationship is known as the dose-response relationship and is fundamentally important in insecticide bioassay (Fig. 15).

Insecticide bioassay with insects or other arthropods often is used to estimate the median lethal dose (LD50) or concentration (LC50) and its associated 95% confidence intervals (95% CI) from a dose-response model. The LD50 or LC50is the dose or concentration of an insecticide required to kill 50% of a given population or strain under the specified conditions. These statistics are adopted as the benchmarks to express the...
