Non-target testing with possible biocontrol agents is an imperative step before a control agent can be approved for release. While biological host range testing often takes the forefront of research on this front, ecological host range testing is another tool that should be used to better understand the biology of any possible control agent. In this presentation, methods and results will be discussed on the ecological host range testing of Anastatus orientalis (Hymenoptera: Eupelmidae). These behavioral tests were conducted to quantify host-seeking behaviors of female A. orientalis when presented with chemical residues left behind by adult female lanternflies during locomotion and egg mass residues from lanternfly ootheca. These tests were conducted using EthoVision XT and The Observer XT software.
