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 />
