Based on the picture, it looks like a false cinch bug. (My certainty in identifications is better when looking at samples with microscope, but I am pretty confident about this one). Generally speaking, Hemipterans don’t become a big problem unless they are present in at greater abundances. It looks like this particular insect could cause problems to young vines, so I would recommend monitoring to see if they exceed an acceptable threshold, which, based on the email below, may be the case.<o:p></o:p></span></p><p class="MsoNormal" style="margin: 0in 0in 0.0001pt;"><span style="background-color: rgba(255, 255, 255, 0);"> </span></p><p class="MsoNormal" style="margin: 0in 0in 0.0001pt;"><span style="background-color: rgba(255, 255, 255, 0);">Here’s some more info, which includes management recommendations: <a href="http://ipm.ucanr.edu/PMG/r302301111.html">http://ipm.ucanr.edu/PMG/r302301111.html</a><o:p></o:p></span></p><p class="MsoNormal" style="margin: 0in 0in 0.0001pt;"><span style="background-color: rgba(255, 255, 255, 0);"> </span></p>Thanks, </div><div>David Goldfarb </div><div>Clos de la Tech </div><div><br><div id="AppleMailSignature">Sent from my iPhone</div><div><br>On Jun 12, 2018, at 12:25 PM, Jeff Griffin <<a href="mailto:griffinhillvineyards@gmail.com">griffinhillvineyards@gmail.com</a>> wrote:<br><br></div><blockquote type="cite"><div><span>Hi VASCM,</span><br><span>We have a pest in our vineyard that showed up in a few spots last year and has expanded to include about half the vineyard this year. It is about the size and appearance of a fruit fly. Before becoming adults and growing wings, they inhabit the ground under dead vegetation in populations that appear like large and very energetic ant colonies. They amass on some green weeds and vine suckers that emerge from the ground. They leave a shiny resin on the suckers, which turn a bronze and whither. In some cases they get into the canopy of stressed vines where do do similar damage.
