Abstract Currently, in Brazil, part of the cucumber production is cultivated in greenhouses, in rotation with bell pepper and tomato. However, this kind of cultivation seems to be contributing to heavy infestations of Bemisia tabaci Mediterranean cryptic species (MED) in cucumbers, which is indeed related to the recent detection of tomato chlorosis virus (ToCV) in this crop. Thus, the present study investigated the settling preference of B. tabaci Middle east Asia-Minor 1 (MEAM1) and MED cryptic species for cucumber, bell pepper, and tomato plants cultivated in the same area. In addition, the settling preference and biological performance of MEAM1 and MED on representative cucumber commercial cultivars were also compared. Cucumber was the most preferred host when compared with tomato and bell pepper for both whiteflies, which were also capable of establishing and ovipositioning in all cucumber cultivars tested. The Mediterranean species showed better adaptability than MEAM1 in almost all cucumber cultivars tested, by showing a better capacity of survival and resulting in a more significant number of adults. When evaluating cultivars, ‘Aodai’ stood out for presenting high MEAM1 nymph mortality, showing that it may be a good option to be implemented in areas with the absence of MED. In contrast, no cultivars were potentially satisfactory for use in the management of MED, reinforcing the need to develop specific management strategies directed for this cryptic whitefly species.

烟粉虱对黄瓜的性能和偏好：了解最近在巴西爆发的地中海隐性物种。

摘要 目前，在巴西，部分黄瓜生产在温室中种植，与甜椒和番茄轮作。然而，这种栽培方式似乎导致了黄瓜中烟粉虱地中海隐性种（MED）的严重侵染，这确实与最近在该作物中检测到的番茄萎黄病病毒（ToCV）有关。因此，本研究调查了粉虱中东小亚 1 (MEAM1) 和 MED 隐性物种对同一地区种植的黄瓜、甜椒和番茄植物的沉降偏好。此外，还比较了 MEAM1 和 MED 对代表性黄瓜商业品种的沉降偏好和生物学性能。与番茄和甜椒相比，黄瓜是两种粉虱的首选宿主，它还能够在所有测试的黄瓜品种中建立和产卵。地中海品种在几乎所有测试的黄瓜品种中都表现出比 MEAM1 更好的适应性，表现出更好的生存能力并导致更多的成虫。在评估品种时，'奥黛' 因 MEAM1 若虫死亡率高而脱颖而出，表明在没有 MED 的地区实施它可能是一个不错的选择。相比之下，没有一个品种在 MED 的管理中可能令人满意，这加强了针对这种神秘的粉虱物种制定特定管理策略的必要性。通过表现出更好的生存能力并导致更多的成年人。在评估品种时，'奥黛' 因 MEAM1 若虫死亡率高而脱颖而出，表明在没有 MED 的地区实施它可能是一个不错的选择。相比之下，没有一个品种在 MED 的管理中可能令人满意，这加强了针对这种神秘的粉虱物种制定特定管理策略的必要性。通过表现出更好的生存能力并导致更多的成年人。在评估品种时，'奥黛' 因 MEAM1 若虫死亡率高而脱颖而出，表明在没有 MED 的地区实施它可能是一个不错的选择。相比之下，没有一个品种在 MED 的管理中可能令人满意，这加强了针对这种神秘的粉虱物种制定特定管理策略的必要性。
