["Boris Uvarov's researches on taxonomy, morphology, biometrics and behaviour of locusts led him to formulate the phase theory respecting those insects, greatly influencing locus research throughout the world. It has also provided a basis for international policy of prevention of locust outbreaks. His studies of outbreaks in Africa contributed much towards establishing correlation between seasonal weather conditions and locus migrations thus providing a basis for forecasting. Other work includes over 150 papers on taxonomy of Orthoptera and many on Orthopterous faunas. Has also done much to encourage locust research and played a leading part in planning international anti-locus measures.".
