Biotype B of the whitefly, Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae), causes considerable losses to growers worldwide. Phytoseiid mites have been successfully used for the control of this pest in several countries. The Brazilian phytoseiid fauna is very diverse and potentially useful for this purpose. The aim of this study was to evaluate five Brazilian populations of phytoseiids as candidates for the control of the whitefly, a serious pest of different crops worldwide. Evaluated species were Amblydromalus limonicus (Garman & McGregor), Amblyseius herbicolus (Chant), Amblyseius largoensis (Muma), Amblyseius tamatavensis (Blommers), and Neoseiulus tunus (De Leon), which are found naturally in Brazil and elsewhere. The work was conducted at 28±1°C, 75±10% relative humidity, and a photoperiod of 12:12 (L:D) h. All evaluated phytoseiids preyed on eggs of B. tabaci, with the highest levels of predation recorded for Am. herbicolus and N. tunus, and highest level of oviposition recorded for Am. tamatavensis. The results show the Brazilian populations of those three species to be promising as control agents of B. tabaci. Aleuroglyphus ovatus (Troupeau) (Acari: Acaridae) was found to be a suitable prey for the mass production of those predators. Complementary studies are considered justified, given the positive results of this study.
烟粉虱的生物型B，即烟粉虱（Gennadius）（半翅目：粉虱科），给全球种植者造成了巨大损失。植绥螨已在多个国家成功用于控制这种害虫。巴西的植绥螨动物群非常多样，可能在此方面具有利用价值。本研究的目的是评估五个巴西植绥螨种群作为控制烟粉虱的候选者，烟粉虱是全球不同作物的一种严重害虫。评估的物种有柠檬钝绥螨（Garman & McGregor）、杂草钝绥螨（Chant）、长毛钝绥螨（Muma）、塔马塔夫钝绥螨（Blommers）和突尼斯新小绥螨（De Leon），这些物种在巴西和其他地方都有自然分布。实验在温度28±1°C、相对湿度75±10%、光周期12:12（L:D）小时的条件下进行。所有评估的植绥螨都捕食烟粉虱的卵，捕食量最高的是杂草钝绥螨和突尼斯新小绥螨，产卵量最高的是塔马塔夫钝绥螨。结果表明这三个物种的巴西种群有望成为烟粉虱的控制剂。卵形嗜卷螨（Troupeau）（蜱螨亚纲：粉螨科）被发现是这些捕食者大规模生产的合适猎物。鉴于本研究的积极结果，认为有必要进行补充研究。
