Abiotic factors on incidence of leaf mite, Schizotetranychus andropogoni (Hirst) and its web colony on Sugarcane plant

The nymph mite showed significantly related to temperature and relative humidity and non significant with rainfall. The adult mite population showed significance relation with temperature, relative humidity and rainfall. The peak mite mean influence was (7.59, 3.36, 5.22, 5.29 & 137.03) recorded in the month of July 2011 (i e. egg, nymph, adult, web size & mite colony), respectively. The average atmospheric temperature during the period was found to be around 31.50°C which favoured in increasing the mite population. The adult mite showed significantly related with temperature, relative humidity and non significance to rainfall. The web size and mite colony showed influence of temperature, relative humidity and non significance to rainfall.
