is an eriophyoid mite pest of the ornamental plant . compromises the esthetics of by inducing erinea formation. Management practices for are currently lacking. This study assessed the potential of commercial biorational (citric acid, potassium salt of fatty acids, garlic, thyme, and mineral oil) and conventional (abamectin, fenpyroximate, bifenthrin, spiromesifen) pesticides under laboratory conditions, using two types of spray applications: (A) curative, after erinea formation, and (B) prophylactic, before erinea formation. In the curative application, abamectin, garlic oil, and mineral oil were most effective; in the prophylactic application, abamectin and mineral oil showed the highest efficacies. Abamectin and mineral oil were further tested under greenhouse conditions. Both treatments effectively controlled by preventing erinea formation over a four-week post-application period, regardless of the application type. At the end of the experiment, mites were extracted from plants. In the curative application, significantly fewer mites were extracted from abamectin and mineral oil treatments than in the control. In the prophylactic application, mites were absent in abamectin and mineral oil treatments but present in the control. Abamectin and mineral oil can be used to manage in landscapes.
是一种观赏植物的瘿螨害虫。通过诱导瘿瘤形成损害其美观。目前缺乏针对它的管理措施。本研究在实验室条件下，使用两种喷雾施药方式评估了商业生物源农药（柠檬酸、脂肪酸钾盐、大蒜、百里香和矿物油）和传统农药（阿维菌素、唑螨酯、联苯菊酯、螺虫乙酯）的防治潜力：（A）治疗性施药，在瘿瘤形成后；（B）预防性施药，在瘿瘤形成前。在治疗性施药中，阿维菌素、大蒜油和矿物油最有效；在预防性施药中，阿维菌素和矿物油显示出最高的防治效果。阿维菌素和矿物油在温室条件下进一步进行了测试。两种处理方式在施药后的四周内都通过防止瘿瘤形成有效地控制了该害虫，且与施药类型无关。在实验结束时，从植株上提取螨类。在治疗性施药中，从阿维菌素和矿物油处理的植株上提取到的螨类明显少于对照。在预防性施药中，阿维菌素和矿物油处理的植株上没有螨类，而对照中有。阿维菌素和矿物油可用于园林中对该害虫的防治。
