Molecular characterization of Bemisia tabaci Genn. spread in Syrian coastal environments using ISSR markers

Abstract EN

According to the International Union for the Conservation of Nature and Natural Resources (IUCN) whitefly Bemisia tabaci Genn.

classified in the globally invasive species.

This study was aimed to characterize this insect molecularly by detecting the genetic variations of its populations on tomato and eggplant in the Syrian coast region.

So, ISSR markers were used to compare the results with these obtained by RAPD.

The results showed that the number of ISSR bands was 102 with 0.75 polymorphism, the variance among populations was 14.3 % and the similarity was 77.5 %.

Our results also showed a weak correlation between the ho^ (tomato and eggplant) and the insect populations (r =0.04).

The dendrogram was divided into two principal groups depending on the heights of sea level and di^ributed in three classes according to the agricultural environment.

A weak correlation was also found between RAPD and ISSR markers using Mantel test r= 0.2.

This Sudy reinforce the efficiency of ISSR marker in detecting the genetic diversity of whitefly Bemisia tabaci Genn.
