Abstract : The eriophyid Cisaberoptus kenyae has become a new pest of mango in Uttar Pradesh, India, with symptoms of white coating on the leaves. Studies on the suitable sample size, monthly population fluctuation, susceptibility of some common varieties and percentage leaf area coated in these varieties by C. kenyae were conducted in Varanasi. The results revealed that a sample size of 2 mm˛ was the most suitable for estimating the population of this mite. The population of C. kenyae increased from November and reached a peak in March and a minimum in December. Severity of incidence varied with variety. Among 5 varieties 'Himsagar' was the most susceptible and 'Chowsa' the least susceptible. Percentage leaf surface area coated was greatest in the variety 'Himsagar' and least in the variety 'Deshi'.
