Fruit Monitoring<br />

•Collect approx 20 to 40 ripening berries evenly<br />

di distributed t ib t d th through h an area where h ttraps showed h d<br />

adult SWD flies.<br />

•Drop fruit into 1qt Ziplock bag <strong>and</strong> lightly crush.<br />

•Add ¼ cup sugar <strong>and</strong> 4 cups water OR 3 Tbsp. to 2<br />

cups water<br />

•Larvae float to top, smaller larvae may y require a h<strong>and</strong><br />

lens to see.<br />

•Alternatively leave fruit inside the Ziplock bag at room<br />

temperature for a few days <strong>and</strong> larvae will emerge<br />

due to warmth.<br />
