中文摘要：B型烟粉虱是全球最严重的番茄害虫之一。这种害虫可导致作物100%减产，以前主要依赖于喷洒复合杀虫剂治理该虫。然而，由于这种治理方式会引起环境问题，现如今需要使用植物性杀虫剂取代复合杀虫剂，作为害虫综合治理（IPM）的策略。本文评估了5种植物精油对番茄中B型烟粉虱的影响，研究结果表明，植物精油PC-EO、AA-EO、PG-EO和PN-EO抑制了B型烟粉虱成虫在番茄植株上的着落和产卵。
外文摘要：The silverleaf whitefly Bemisia tabaci (Genn.) biotype B (Hemiptera: Aleyrodidae) is one of the most severe tomato pests in the world. The damage caused by this insect may compromise up to 100% of crop production, and management of this pest has relied on spraying of synthetic insecticides. However, due to the environmental issues associated with this practice, alternative methods such as the use of botanical pesticides are now used as a strategy of integrated pest management (IPM). We evaluated the effects of essential oils of five plant species on B. tabaci biotype B in tomato and demonstrate that the essential oils (0.5%) of Piper callosum (PC-EO), Adenocalymma alliaceum (AA-EO), Pelargonium graveolens (PG-EO), and Plectranthus neochilus (PN-EO) inhibit the settlement and oviposition of B. tabaci biotype B adults in tomato plants. In fumigation tests, A. alliaceum (AA-EO) at 0.4 mu L/L of air after 72 h and 0.1 mu L/L of air after 6 h was the most effective against nymphs and adults of B. tabaci biotype B, respectively. The major chemical constituents of PC-EO were identified as being safrole (29.3%), alpha-pinene (19.2%), and beta-pinene (14.3%), whereas diallyl trisulfide (66.9%) and diallyl disulfide (23.3%) were the major compounds identified in AA-EO. This is the first report on the reduction of oviposition by the use of P. callosum (PC-EO) and A. alliaceum (AA-EO). In addition, the fumigant effect of A. alliaceum (AA-EO) on nymphs and adults has also been reported here for the first time.
