The mobility and the origin of BW infestations at the Canary Islands (Tenerife, La Gomera and La Palma) have been analysed using Random Amplified Polymorphic DNA (RAPD) as molecular markers. Populations from Costa Rica, Colombia, Uganda and Madeira were also included for comparison. One hundred and fifteen reproducible bands from eight primers were obtained. The level of polymorphism in the populations from the Canary Islands (40-62%) was in the range of those found in other populations. Nei's genetic distances, pair-wise fixation index (FST) values indicate that the closest populations are Tenerife populations among themselves (Nei's genetic distance=0.054-0.100; FST=0.091-0.157) and Costa Rica and Colombia populations (Nei's genetic distance=0.049; FST=0.113). Our results indicate the existence of BW local biotypes with limited gene flow and affected by genetic drift. These results are compatible with a unique event of colonization at Tenerife; whereas, the outbreaks in La Gomera and La Palma may come from independent introductions. The Madeira population is phylogenetically and geographically closer to the Canary Islands populations, suggesting that it is the most likely source of the insects introduced in the Canary Islands.10aCosmopolites sordidus1 aMagana, C.1 aBeroiz, B.1 aHernandez-Crespo, P.1 ade Oca, Montes1 aCarnego, A.1 aOrtego, F.1 aCastanera, P.  uhttps://weevil.myspecies.info/population-structure-banana-weevil-introduced-pest-canary-islands-studied-rapd-analysis-002167nas a2200229   4500008004100000020001400041245011400055210006900169260001300238300001200251490000700263520139600270653002601666100001501692700001501707700002501722700001901747700001601766700001501782700001801797856012201815       2007                        eng d  a0007-485300aPopulation structure of the banana weevil, an introduced pest in the Canary Islands, studied by RAPD analysis0 aPopulation structure of the banana weevil an introduced pest in   cDecember  a585-5900 v973 aThe banana weevil (BW), Cosmopolites sordidus (Coleoptera: Curculionidae), is one of the most important insect pests of bananas and plantains.
