Abstract:
Most of the published methods for DNA isolation from vectors (insects) are not always effective in mealy-bugs, aphids and leafhoppers because they have high amount of polyphenols in their body systems. A simple, rapid, reliable labor-effective and carcinogenic compound-free salting out method for isolation of high molecular DNA from these insects is described. The ratio of OD260/OD280 ranged between 1.8 to 2.0. The method was successfully applied to Rolling Circle Amplification and in restriction analysis, indicating the removal of the common inhibitors.
