Abstract:
... Mosquito-borne disease research in India has remained stagnant for decades, and will continue to remain. This is so as the hard work in the field by entomologists has given way to comfortable work in air-conditioned laboratories, with computer as the main tool. Critical reviews are being written by men not of science, and also others, but our government totally ignores them. ...
