摘要

本研究分析了迷迭香、薄荷、互叶千层和桃金娘精油及其混合物在实验室和保护性栽培中对二斑叶螨成年雌性的残留接触毒性和驱避作用。桃金娘精油的LC50为0.55 ml L-1，而R.officinalis+M.piperita+M.alternifolia+桃金娘、C.myrrha+M.piprita和C.myrrha+M.alternitfolia的混合物分别显示68%、60%和36%的死亡率。桃金娘和互叶互叶互叶的精油分别显示出95%和70%的排斥性。C.myrrha+M.alternifolia、C.myrrhara+M.piperita和C.myrrha+R.officinalis的混合物分别提供85%、74%和73%的排斥性。在保护性栽培中，C.myrrha精油残留接触的毒性表现出93%的死亡率，而杀螨剂苯吡肟酯表现出80%的死亡率。精油成分为桉树醇（49.66%）、胡椒薄荷醇（48.53%）、互叶萜品醇-4-醇（48.93%）和苯甲酸苄酯（97.71%）。然而，还需要进一步的研究来评估成本效益比以及对非目标生物的影响。

Acaricidal activity and repellency of commercial essential oils on Tetranychus urticae in vitro and protected cultivation

This study analyzed the toxicity by residual contact and the repellency effect of the essential oils of Rosmarinus officinalis, Mentha piperita, Melaleuca alternifolia, and Commiphora myrrha and their mixtures on adult females of Tetranychus urticae in laboratory and protected cultivation. The essential oil of C. myrrha exhibited a LC50 of 0.55 ml L-1, and the mixtures R. officinalis + M. piperita + M. alternifolia + C. myrrha, C. myrrha + M. piperita, and C. myrrha + M. alternifolia showed 68%, 60%, and 36% mortality, respectively. The essential oils of C. myrrha and M. alternifolia showed 95 and 70% of repellency, respectively. Mixtures of C. myrrha + M. alternifolia, C. myrrha + M. piperita, and C. myrrha + R. officinalis provided repellency of 85, 74 and 73%, respectively. Toxicity by residual contact of the essential oil of C. myrrha in protected cultivation exhibited 93% mortality, while the acaricide fenpyroximate showed 80%. The constituents of essential oils were eucalyptol (49.66%), M. piperita menthol (48.53%), M. alternifolia terpinen-4-ol (48.93%), and C. myrrha benzyl benzoate (97.71%). The essential oil of C. myrrha and the mixtures R. officinalis + M. piperita + M. alternifolia + C. myrrha and C. myrrha + M. piperita showed significant mortality. However, further studies are needed to assess the cost/benefit ratio and the effects on non-target organisms.
