中文摘要：烟粉虱是许多园艺蔬菜上一种重要的害虫。烟粉虱携带传播新德里番茄曲叶病（ToLCNDV），可对西葫芦造成重大损害。害虫和病害均已在欧洲最大的蔬菜生产地区西班牙东南部的大田和温室作物上建立。已知胡瓜钝绥螨可通过取食烟粉虱的卵和幼虫有效控制甜椒和黄瓜等作物上的烟粉虱种群。然而，还未有关于这种捕食螨有效控制西葫芦烟粉虱的报道。本研究通过在幼苗上预投放胡瓜钝绥螨来评估其减少烟粉虱种群和ToLCNDV传播的潜在可能性。研究结果表明，在有捕食螨的西葫芦上烟粉虱成虫及产在西葫芦上的卵数量明显减少，由此可见，胡瓜钝绥螨对烟粉虱的定植与繁殖有显著负面影响，但对ToLCNDV的初期侵染没有显著影响。
外文摘要：The tobacco whitefly, Bemisia tabaci (Gennadius) (Homoptera: Aleyrodidae), is a serious pest of vegetables in many horticulture systems. It vectors the Tomato leaf curl New Delhi virus (ToLCNDV) which causes considerable damage in zucchini crops. Both pest and the disease are well established in field and greenhouse crops in the southeast of Spain, the largest vegetable growing area in Europe. The predatory mite Amblyseius swirskii Athias-Henriot (Arachnida: Phytoseiidae) is known to effectively manage B. tabaci populations in crops such as sweet pepper and cucumber, feeding on eggs and crawlers of this pest. However, there are no reports on the effectiveness of predatory mites against tobacco whitefly in zucchini crops. The potential to reduce whitefly populations as well as the spread of ToLCNDV in zucchini was evaluated by the pre-installation of A. swirskii in seedlings. Results showed that the number of adult whiteflies and deposited eggs on zucchini plants were significantly lower on plants with the phytoseiid predator, showing a significant negative impact of A. swirskii on B. tabaci colonization and reproduction but not on the primary infection with ToLCNDV. However, the pre-release of the predatory mites resulted in a strong decrease in eggs and subsequently emerging adults of whiteflies relative to plants without predators, and a significant reduction in secondary spread of the virus.
