Abstract
Aleurodicus dispersus Russell, commonly known as spiralling whitefly (SWF), is a noxious polyphagous sucking pest infesting on an array of agricultural and horticultural crops, both in the glasshouse and field conditions. Bacterial endosymbionts associated with insects provide several benefits for the survival and reproduction of their host. Since endosymbionts play a vital role in the physiology of their host, identification of bacteria associated with SWF will entail the formulation of appropriate strategy to contain the noxious pest. In the present investigation bacterial strains associated with A. dispersus Russell were isolated and identified based on the biochemical parameters and comparative analysis of 16S rDNA sequences. Biochemical tests with VITEK 2 analyser and DNA revealed that there are four different strains of bacterium belonging to three different genera -- Bacillus, Staphylococcus and Pantoea associated with SFW.
