Project Number: 1926-22000-023-24
Start Date: Aug 01, 2013
End Date: Jun 30, 2015
Evaluations of egg and larval survival and mortality factors will be based on EAB life tables developed from marked cohorts of eggs and larvae on common American ash trees at a minimum of four field sites in natural forests, where some indigenous parasitoids may have become associated with EAB, and the three introduced Chinese parasitoids (Oobius agrili, Tetrastichus planipennisi, Spathius agrili) either have already been released or will be released in the first year of the study. Naturally occurring native species (if any) in each of the study sites will be treated as sequential and/or contemporary factors inflicting mortality of EAB along with the previously introduced Chinese parasitoids. If work from associated EAB projects leads to successful discovery and introduction of new species of parasitoids from Russia and/or China, these species will be introduced and then included in the evaluation studies.
