“…Two other microsatellite banks recently published (De Barro et al, 2003 ;Tsagkarakou & Roditakis, 2003) will provide more microsatellite markers which might be very interesting for generalizing our kind of study to largescale sampling of different biotypes.…”

Microsatellites reveal extensive geographical, ecological and genetic contacts between invasive and indigenous whitefly biotypes in an insular environment

SummaryHuman-mediated bioinvasions provide the opportunity to study the early stages of contact between formerly allopatric, divergent populations of a species. However, when invasive and resident populations are morphologically similar, it may be very difficult to assess their distribution in the field, as well as the extent of ecological overlap and genetic exchanges between invasive and resident populations. We here illustrate the use of data obtained from a set of eight microsatellite markers together with Bayesian clustering methods to document invasions in a group of major tropical pests, Bemisia tabaci, which comprises several morphologically indistinguishable biotypes with different agronomic impacts. We focus on the island of La Re´union, where an invasive biotype (B) has recently been introduced and now interacts with the resident biotype (Ms). The temporal and spatial distribution, host-plant range and genetic structure of both biotypes are investigated. We showed (i) that, without prior information, clustering methods separate two groups of individuals that can safely be identified as the B and Ms biotypes; (ii) that the B biotype has invaded all regions of the island, and showed no signs of genetic founder effect relative to the Ms biotype ; (iii) that the B and Ms biotypes coexist in sympatry throughout most of their geographical ranges, although they tend to segregate into different host plants ; and finally (iv) that asymmetrical and locus-specific introgression occurs between the two biotypes when they are in syntopy.

“…This may be due to the widespread distribution of B. tabaci throughout the world, besides the fact that the pest is a species complex with a number of biotypes which are morphologically indistinguishable as only known recently by modern molecular techniques (Byrne and Devonshire, 1991;De Barro et al, 2003;Viscarret et al, 2003). For instances, A, Q, An, Nauru and cassava biotypes are distributed in America, Mediterranean, Australia, Pacific region and Africa, respectively.…”

Alien insect species affecting agriculture and natural resources in Sudan

Agricultural crops in Sudan are usually attacked by different local pests at variable levels based on the prevailing climatic and ecological conditions. However, with the modernization of agriculture coupled with the rapid movement of global trade during the last decades, new species of insects were accidentally introduced to the country. Unfortunately, most of these insects are potentially harmful species, hence imposing serious threats to agriculture and/or natural resources. This paper sheds light on the important established alien insect species, their original homes and the main host plants affected. More than twenty five species believed to be exotic were listed, and brief accounts were given on important ones. They include devastating pests on field and horticultural crops, store products and natural flora, among which are species of stemborers, bollworms, leafminers, fruitflies, scale insects, beetles and others. The paper stressed the steady increase in the frequency of introductions as a consequence of trade globalization, and warned from the entry of some new invasive species in the near future. Finally, the paper emphasizes the importance of cooperation in combating alien pests, particularly through biological approach, and asks for upgrading of quarantine measures in our countries so as to keep pace with the accelerating world trade.
