Abstract
The whitefly Bemisia tabaci (Gennadius) is one of the most important pests causing economic losses in a variety of cropping systems around the world. This species was recently found in a coastal region of Colombia and has now spread inland. To investigate this invasive process, the genetic structure of B. tabaci was examined in 8 sampling locations from 2 infested regions (coastal, inland) using 9 microsatellite markers and the mitochondrial COI gene. The mitochondrial analysis indicated that only the invasive species of the B. tabaci complex Middle East-Asia Minor 1 (MEAM 1 known previously as biotype B) was present. The microsatellite data pointed to genetic differences among the regions a..

We thank the "Bean Entomology Lab" at the International Center for Tropical Agriculture (CIAT) in Colombia and Dr. Maria del Rosario Manzano for field work assistance as well as the "Molecular Biology and Ecogenetic Studies Team" (Universidad del Valle), especially to Biologist Diana L. Juvinao, Cinthya Saldana, and Vanessa Munoz for help with sampling; to the farmers for permission to collect the whitefly samples in their crops; and we also thank Dr. De Barro for some advice with selecting the right microsatellites for this study. Some support was provided through the Australian Research Council through their Fellowship scheme.
