ABSTRACT
The assumption that insects generally respond to toxicants in direct proportion to their body weight has led some investigators
to compensate for effects of weight by proportionally adjusting doses to the weight of the test subjects during the application process. The adjustment-for example, the application of l
μ
l/100 mg body weight-was (and unfortunately still is) used routinely. Results of experiments with locust species,
and several species of lepidoptera,
suggested that such dose adjustments were appropriate. But evidence that responses do not vary as simple functions of body weight was also described by Bliss
and Way.
