烟粉虱Bemisia tabaci（Genn.）生物型B（半翅目：粉虱科）是番茄Solanum lycopersicum（L.）导致果实不规则成熟并传播几种植物病原双生病毒。该害虫的管理通常基于重复喷洒合成农药，造成严重的环境破坏和昆虫种群抗性的增加。本研究采用化学气相色谱法、气相色谱法和气相色谱法，胜红蓟，小茴香，白唇藓Lippia alba（Mill.）N. E. Br.，香茶，和万寿菊（Tagetes erecta L.）研究了它们对B的驱避和产卵忌避作用。烟粉虱生物型B在番茄上的分布。在多项选择试验中，桃金娘精油是最有效的驱避剂和产卵忌避剂。精油A. conyzoides和T.直立对雌性B有显著的阻吓作用。烟粉虱生物型B在处理的番茄叶片上产卵。经鉴定，（E）-香芹烯（30.67%）、单萜类化合物α-蒎烯（15.02%）和α-崖柏烯（11.70%）为金鱼草挥发油的主要成分。实验结果表明，桃金娘精油和其他精油对B的产卵和定居有一定的抑制作用。烟粉虱生物型B在番茄上的分布。
The silverleaf whitefly Bemisia tabaci (Genn.) biotype B (Hemiptera: Aleyrodidae) is an economically important pest of tomatoes Solanum lycopersicum (L.), causing irregular ripening on fruits and transmitting several plant pathogenic geminiviruses. The management of this pest is commonly based on repetitive spraying with synthetic pesticides, causing serious environmental damages and increase of resistance by insect population. In the present study, essential oils from the leaves of Artemisia camphorata Vill., Ageratum conyzoides L., Foeniculum vulgare Mill., Lippia alba (Mill.) N. E. Br., Plectranthus neochilus Schltr., and Tagetes erecta L. were investigated for their possible repellent and oviposition-deterrent effects against B. tabaci biotype B on tomato. In a multi-choice assay, P. neochilus essential oil was the most active repellent and oviposition deterrent. Essential oils of A. conyzoides and T. erecta significantly deterred the female B. tabaci biotype B from laying eggs on treated tomato leaflets compared with the control. (E)-Caryophyllene (30.67 %) and the monoterpenes alpha-pinene (15.02 %) and alpha-thujene (11.70 %) were identified as the major constituents of the essential oil of P. neochilus. Our findings demonstrated the potential of essential oil of P. neochilus and other oils in the reduction of settlement and oviposition of B. tabaci biotype B on tomato.
