ABSTRACT
In this chapter, the area of insect pathology is used to demonstrate an approach to time to event analysis that has much in common with ecotoxicology. Insect pathology involves the study of mortality when insects are challenged by pathogenic microorganisms. The time to response of such studies is of particular interest because pathogens (biopesticides) do not have the immediacy of chemical control agents. Two examples are used to demonstrate several methods used in insect pathology for analyzing time to response. The examples illustrate both a simple parametric analysis, and the
use of survival analysis in a semi-parametric context. It is shown that, although a modeling approach is used, the methods are robust and have considerable potential for routine time to response analysis in ecotoxicology.
