Abstract

Woodlice, Tracheoniscus rathkei, fed 100 to 1,000 PPM DDT and its metabolites DDE and DDA, were found to have significantly reduced survival times when exposed to environ­mental stress in the form of low humidity or high temperature. Such sensitivity to stress could result in significantly lower population density during some months of the year. The increase in unconsolidated organic materials which could result if population density were reduced might affect the structure and function of the community and the ecosystem.
