Population dynamics of phytophagous mite, Tetranychus ludeni Zacher on cowpea in relation to abiotic conditions of Varanasi region

Dharmendra Kumar, M Raghuraman, Ramesh Singh Yadav, and Mukesh Kumar Singh

The field experiment was conducted with a view to study the fluctuation of phytophagous mite’s (Tetranychus ludeni Zacher) population and their relation to prevailing weather variables during 2010 and 2011 at the farmer Salik Ram field, Village Raipur, Varanasi, the cowpea variety Kashi kanchan was sown on 15 February 2010 and 20 February 2011 respectively. The result reveals that the mite population commenced on 10th standard week in both the year. The population of mite was counted per leaf basis. The highest population buildup of mites was recorded on 18th standard week (51.80) in 2010 while in 2011 the maximum buildup of mite’s population was recorded in a 20th standard week (52.64). On an average the maximum mite’s population buildup was recorded in the May in both the year. Positive correlation were shown by mite (Tetranychus ludeni Zacher) with average temperature, sunshine hours and wind velocity, where as negative correlation was found with relative humidity and rainfall in mites population.
