Life tables may be used as a quantitative tool to assess the impact of natural enemies on pests. One of the critical challenges in constructing life tables for concealed insect pests such as emerald ash borer is to create or establish cohorts that can be used to quantify the contemporary contributions of various mortality factors, including insect parasitoids. The present study investigates and compares techniques to create egg and larval cohorts of emerald ash borer for measuring the impact of several introduced egg and larval parasitoids.
