26 Progress: Know when nd where SWD occurs in estern WA Hve workble, conservtive pproch to control Know which pesticides re effective nd how long they lst Know when cherries become susceptible Hve improved the sensitivity of the monitoring system

27 Needs work: Bsic ecology where do SWD overwinter Models DD, popultion Biocontrol ntives not working tht well, more hope for imports IPM not so much; threshold is too conservtive Need better trp in order to set threshold Need broder rnge of pesticides for resistnce mngement Need softer controls
