The multicoloured Asian lady beetle, Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae), has become a pest in North American vineyards during harvest due to its adverse effects on wine quality. This study evaluated alternative products that may be suitable for use in vineyards as repellents to the beetle. Products were screened as repellent for multicoloured Asian lady beetle in short-term laboratory trials. Thirteen products significantly reduced the number of beetles on grapes, Vitis vinifera (Vitaceae). Products that showed a 50% or greater repellency were evaluated for residual repellency 24, 48, and 72 hours after application. In these trials, pine oil was highly repellent at each testing period, whereas the repellency of most other products decreased over time. Eight repellent compounds were evaluated in field trials in commercial vineyards that had high multicoloured Asian lady beetle populations. The number of beetles on vines was counted 2–6 and 24–28 hours after application. In the field, the most effective repellents overall were Biobenton and Buran, which reduced the number of multicoloured Asian lady beetles by 39 and 34%, respectively. The discovery of new repellents of multicoloured Asian lady beetle provides an opportunity to improve management of the pest in vineyards and to reduce risk of wine taint without using broad-spectrum insecticides.

五彩的亚洲瓢虫Harmonia axyridis (Pallas) (鞘翅目：瓢虫科)，由于对葡萄酒品质产生不利影响，在收获期间已成为北美葡萄园的害虫。这项研究评估了可能适合在葡萄园中用作甲虫驱虫剂的替代产品。在短期实验室试验中，产品被筛选为对多色亚洲瓢虫的驱虫剂。13 款产品显着减少葡萄、Vitis vinifera上的甲虫数量（葡萄科）。应用后 24、48 和 72 小时，对显示出 50% 或更高防水性的产品进行评估。在这些试验中，松油在每个测试期间都具有高度的驱避性，​​而大多数其他产品的驱避性随着时间的推移而下降。在具有大量多色亚洲瓢虫种群的商业葡萄园的田间试验中评估了八种驱虫化合物。在施用后 2-6 小时和 24-28 小时计算葡萄藤上甲虫的数量。在该领域，总体上最有效的驱虫剂是 Biobenton 和 Buran，它们分别将多色亚洲瓢虫的数量减少了 39% 和 34%。
