Social wasps can be serious pests in fruit growing plantings and are becoming increasingly problematic for grape growers. In this study, we conducted two experiments to assess the species composition and seasonal phenology of social wasps in Wisconsin vineyards in 2015 and 2017. In 2015, three attractants were used: (1) wine; (2) heptyl butyrate (HB); and (3) acetic acid and isobutanol (AAIB) and in 2017, two attractants were used: HB and AAIB. In both years, the same eight species were trapped from the genera , , and . The predominant wasp species trapped were , , , and in 2015 and , , , and in 2017, in order of total abundance. The populations of decreased in 2017 compared to 2015, indicating large inter-annual variation. In both years, AAIB lures trapped significantly more , , and , the three most prevalent species during grape harvest, than HB, whereas HB lures trapped more than AAIB. Wine was generally attractive to all species in 2015. This study identifies for the first time the wasp species present in Wisconsin commercial vineyards using chemical attractants. This knowledge, along with the seasonal phenology of these pest species, will help facilitate the development of management strategies for social wasps in commercial vineyards.
群居黄蜂在水果种植园中可能成为严重害虫，对葡萄种植者而言问题日益突出。在本研究中，我们于2015年和2017年开展了两项实验，以评估威斯康星州葡萄园群居黄蜂的物种组成和季节性物候。2015年使用了三种引诱剂：（1）葡萄酒；（2）丁酸庚酯（HB）；（3）乙酸和异丁醇（AAIB），2017年使用了两种引诱剂：HB和AAIB。在这两年中，从[具体属名]属中诱捕到了相同的8个物种。2015年诱捕到的主要黄蜂物种按总捕获量排序依次为[具体物种1]、[具体物种2]、[具体物种3]和[具体物种4]，2017年为[具体物种5]、[具体物种6]、[具体物种7]和[具体物种8]。与2015年相比，2017年[具体物种]的数量减少，表明年际间变化较大。在这两年中，AAIB诱捕器捕获的葡萄收获期间最常见的三种物种[具体物种1]、[具体物种2]和[具体物种3]显著多于HB诱捕器，而HB诱捕器捕获的[具体物种]比AAIB诱捕器多。2015年葡萄酒通常对所有物种都有吸引力。本研究首次使用化学引诱剂确定了威斯康星州商业葡萄园中存在的黄蜂物种。这些知识，连同这些害虫物种的季节性物候，将有助于推动商业葡萄园群居黄蜂管理策略的制定。
