Effect of abiotic factors on population dynamics of Tetranychus urticae Koch on brinjal crop

Abstract

An experiment was conducted during March 2010 to August 2010 at the Pili Kothi farm of T.D. College Jaunpur to study the abundance of mite population Tetranychus urticae on brinjal crop. The highest population was recorded in the month of May and lowest population was recorded in the month of March. A positive correlation was observed between population and temperature and negative correlation was observed between population with rain fall and relative humidity.
