Abstract

ABSTRACT We surveyed the mite fauna on three vegetable crops (cucumber, eggplant, and pepper) in plastic-houses throughout the autumn of 2020 by taking weekly leaf samples. These samples revealed several plant-feeding and predatory mites belonging to 13 species in ten genera and five families, as well as some insect pests. Tetranychus urticae Koch (Tetranychidae) was a significant pest in all three crops and Integrated Pest Management (IPM) control was used for its control. A bioassay was performed to evaluate the effect of a mixture of essential oils (clove, lavender, eucalyptus, and sweet orange) on T. urticae and its associated predator, Phytoseiulus persimilis Athias-Henriot (Phytoseiidae). The lethal concentration of this essential oil mixture determined by laboratory bioassay, was used on eggplant and cucumber crops in plastic-houses. The active ingredients of the tested oil mixture were determined using GC-MS analysis of the mixed essential oil. The total constituents of the mixed essential oil were identified as 43 compounds, primarily d-limonene, but also monoterpenes, sesquiterpens, diterpens, sestetraterpens, triterpens, and tetraterpens.

塑料大棚蔬菜上的螨虫生物多样性以及一种精油混合物对荨麻蠹蛾和柿螨的功效

摘要 2020 年秋季，我们通过每周采集叶片样本，对塑料大棚内的三种蔬菜作物（黄瓜、茄子和辣椒）上的螨类进行了调查。这些样本揭示了属于 10 属 5 科 13 种的植食性和捕食性螨虫以及一些害虫。Tetranychus urticae Koch (Tetranychidae)是所有三种作物中的主要害虫，采用虫害综合防治（IPM）方法对其进行防治。生物测定评估了精油（丁香、薰衣草、桉树和甜橙）混合物对 T. urticae 及其相关天敌 Phytoseiulus persimilis Athias-Henriot （Phytoseiidae）的影响。这种精油混合物的致死浓度是通过实验室生物测定确定的，用于塑料大棚中的茄子和黄瓜作物。通过对混合精油进行气相色谱-质谱分析，确定了测试精油混合物的有效成分。经鉴定，混合精油的总成分为 43 种化合物，主要是二柠檬烯，还有单萜、倍半萜、二萜、雌四萜、三萜和四萜。

期刊介绍： The International Journal of Acarology has a global readership and publishes original research and review papers on a wide variety of acarological subjects including: • mite and tick behavior • biochemistry • biology • control • ecology • evolution • morphology • physiology • systematics • taxonomy (single species descriptions are discouraged unless accompanied by additional new information on ecology, biology, systematics, etc.) All submitted manuscripts are subject to initial appraisal by the Editor. If the English is not of a quality suitable for reviewers, the manuscript will be returned. If found suitable for further consideration, it will be submitted to peer review by independent, anonymous expert referees. All peer review is single blind.
