Natural mortality factors acting on western corn rootworm populations: a comparison between the United States and Central Europe.

Abstract

This chapter provides details on natural mortality factors acting on the life stages of Diabrotica virgifera virgifera, and summarizes statistically reliable information compiled and published over the last 40 years. Reported information on mortality factors acting on the egg, larval, pupal and adult stages of D. virgifera virgifera in the USA have been compiled into comparable units and compared directly with the results obtained from similar life table studies on D. virgifera virgifera in Hungary, representing mortality factors in Central Europe.
