ABSTRACT
In this chapter, the authors present some of the general approaches for determining when to begin sampling and discuss some considerations of host, pest, and environment that pertain to this question. They explore some of the techniques associated with initiating sampling programs. The authors conclude with a discussion of practical considerations in initiating sampling programs. They also present key issues as they relate to initiating sampling programs and refer to major reviews that can guide the reader to additional information as desired. There is a large volume of literature on questions of temperature and insect development. The authors then present key issues as they relate to initiating sampling programs and refer to major reviews that can guide the reader to additional information as desired. The points consider are the physical basis for temperature-development relationships, approaches for estimating development, limitations to existing methods, and using estimates of development to start sampling programs.
