Comments: Aleurothrixus floccosus , commonly known as the “woolly whitefly”, is an economically important pest of citrus. In the field, it can be easily distinguished by the finely tangled flocculent white wax obscuring the immature stages ( Fig. 44, 45), and copious excretion of honeydew. The species is native to the neotropical region, and has been slowly extending its range for many years. In mainland Spain, A. floccosus was introduced into Málaga by 1968 and spread across all the citrus-growing areas in the country in just a few years ( Llorens-Climent & Garrido-Vivas, 1992). The first record of this species in the Canary Islands was from 1966 ( Anonymous, 1971); however, material collected from the Canaries in 1937 is deposited at the BMNH. Currently, in the archipelago it is a relatively minor pest of Citrus and Codiaeum variegatum , an ornamental shrub, as the parasitoid Cales noacki (Howard) ( Hymenoptera , Aphelinidae ) is naturally controlling A. floccosus populations ( Hernández-Suárez, 1999). Both pale-puparium and dark-puparium populations of A. floccosus have been observed in the Canary Islands, and elsewhere. This variation in puparial cuticular pigmentation between populations was mentioned by Quaintance & Baker (1917), Bink-Moenen (1983) and Martin (1999) and it suggests the possible existence of several races of this species.
