After considering this PRA, it was decided not to add Aleurotrachelus trachoides to EPPO A1 Lists of pests recommended for regulation as quarantine pests. 

The endangered area is considered to be the southern part of the Mediterranean Basin (south of a line from southern Spain to southern Turkey) and southern Portugal, as well as indoors production of Solanaceae throughout the PRA area. There is a high uncertainty on the limits of the endangered area because of lack of data on the adaptability of the pest. 

Overall assessment of risk: A. trachoides is considered to pose a low phytosanitary risk for the endangered area. A. trachoides is a whitefly native to the neotropical region; it has spread to the Pacific, and there are recent findings in Africa. It is oligophagous, with a preference for Solanaceae. The life stages of A. trachoides are present mostly on leaves, and occasionally on other green parts. A. trachoides causes direct damage by feeding on plants and through the production of honeydew on leaves and fruits, which in turn favour the development of sooty moulds. Entry is considered possible on plants for planting, on fruit with green parts (incl. tomato), and on cut plant parts (cut flowers and branches, cut herbs, leafy vegetables). A. trachoides may cause outbreaks and transient populations under protected conditions (where it may cause damage even it is does not establish permanently). It is expected to have a moderate impact, and is not known as a virus vector. It may have impact especially on hot and sweet peppers, but also tomato and eggplant. Spread will mainly be with traded commodities rather than natural spread. 

Phytosanitary Measures to reduce the probability of entry: No phytosanitary measures are recommended as the risk is considered low
