Abstract:

This study reviewed the main factors of accumulation, distribution and excretion of some significant environmental pollutants in insects. It is found that accumulation of heavy metals was a continuous and dynamic process, which depends largely on the stress time, feeding amount, and excretion capacity of heavy metals for insects. And the pollutants are mainly accumulated in digestive tracts. Detoxification of insects to those heavy metals is by means of feces, ecdysis molt and metamorphosis. It is suggested that future study should focus on metal pollution to insects in successive generations.
