“…It lays eggs in a typical spiral pattern, so it is more commonly known worldwide as 'spiralling whitefly'. This whitefly is native to the Caribbean region and Central America (Russell, 1965). The insect is highly polyphagous, and has been recorded on more than 100 plants belonging to 38 genera and 27 families, including many vegetables, ornamental and fruit crops (Waterhouse and Norris, 1989;Charati et al, 2003).…”

ABSTRACT. Ten microsatellite markers were isolated and characterized from Aleurodicus dispersus, the spiraling whitefly, an exotic pest species that is considered to be one of the most serious agricultural pests on Hainan Island, China. The polymorphism of these loci was examined in individual whiteflies from Hainan Island and from the Canary Islands. All loci were polymorphic, with two to four alleles per locus. Mean observed and expected heterozygosity values were 0.773 and 0.585, respectively. These microsatellite markers provide powerful tools for ecological, epidemiological and population genetic studies on this highly invasive insect. Thirty insects were collected

“…Fortunately biological control is easily achieved using a variety of specialist natural enemies (Kumashiro et al 1983;Neuenschwander 1996;D'Almeida et al 1998;Mani et al 2004). The results of these studies and the observation that A. dispersus is generally rare in its native range (Russell 1965;Waterhouse and Norris 1989), suggest that 'enemy release' is important in determining the success of A. dispersus in areas where its natural enemies are absent.…”

“…Since 1962 A. dispersus has spread rapidly around the tropics from its native range of Central America and the Caribbean (Russell 1965;Waterhouse and Norris 1989;Ramani et al 2002). Typically A. dispersus populations increase dramatically during the early stages of an invasion and then stabilise after a number of years at levels many orders of magnitude higher than in their native range (Ramani 2000;Ramani et al 2002).…”

The role of exotic plants in the invasion of Seychelles by the polyphagous insect Aleurodicus dispersus: a phylogenetically controlled analysis

The accidental introduction of the spiralling whitefly, Aleurodicus dispersus Russell (Homoptera: Aleyrodidae) to Seychelles in late 2003 is exploited during early 2005 to study interactions between A. dispersus, native and exotic host plants and their associated arthropod fauna. The numbers of A. dispersus egg spirals and pupae, predator and herbivore taxa were recorded for eight related native/exotic pairs of host plants found on Mahé, the largest island in Seychelles. Our data revealed no significant difference in herbivore density (excluding A. dispersus) between related native and exotic plants, which suggests that the exotic plants do not benefit from 'enemy release'. There were also no differences in predator density, or combined species richness between native and exotic plants. Together these data suggest that 'biotic resistance' to invasion is also unlikely. Despite the apparent lack of differences in community structure significantly fewer A. dispersus egg spirals and pupae were found on the native plants than on the exotic plants. Additional data on A. dispersus density were collected on Cousin Island, a managed nature reserve in which exotic plants are carefully controlled. Significantly higher densities of A. dispersus were observed on Mahé, where exotic plants are abundant, than on Cousin. These data suggest that the rapid invasion of Seychelles by A. dispersus may largely be due to the high proportion of plant species that are both exotic and hosts of A. dispersus; no support was found for either the 'enemy release' or the 'biotic resistance' hypotheses.

The spiraling whitefly Aleurodicus dispersus (Russell) is an insect pest that causes substantial damage to ornamental plants, shade trees and food crops. It was first observed in Benin in 1993. Two host specific parasitoids, Encarsia dispersa and E. guadeloupae, fortuitously introduced with its host, were recovered in the second half of 1993 in Southern Benin. Survey results from 1993 to 1995 (already published) showed the decline in the population of A. dispersus due to the parasitoids, and the spread from Cotonou (6°10 0 N) in a northern directions of both parasitoids and their host. Results from similar field surveys from 1996 to 2003 document that the spiraling whitefly and both its parasitoids spread to Natitingou (10°20 0 N, 540 km) in 1995 and Bembereke (10°14 0 N) in 1996, whereby E. dispersa arrived within less than a year of its host and quickly became dominant in the two localities on the northern front. In subsequent years, the parasitoids established their geographical niches, with E. dispersa being more abundant (up to 89%) in the coastal south bellow latitude 7°30 0 N and E. guadeloupae (up to 84%) in the north between latitudes 7°30 0 and 10°30 0 N. We conclude that the gradual replacement observed over ten years and over 500 km has to do with longitudinal shifts in the length and severity of the dry season and the higher susceptibility to these conditions by E. dispersa.
