European red mite is a serious problem of apple in Himachal Pradesh. At present more than 80 % orchards have been found infested with European red mite. It sucks cell sap from leaves which resulted into poor quality of fruits. Present studies were undertaken to see the effect of environmental factors e.g. temperature and relative humidity on the buildup of mite population in the apple trees at RHRS, Mashobra. The predicted optimum temperature and relative humidity was calculated by using Beta model is 21.45oC and <85% respectively. Since from the last few years regional observation and experimental database on prediction of pest attack on crop about infection index correspondence to above mentioned environmental parameters was prepared using software Microsoft EXCEL. After that from collected data a mathematical prediction model was developed using the MATLAB as software tool. A generalized form of Beta model was provided to best fit in the data. The value of R2 we observed for eggs and motiles was 82.8 and 84.5 respectively.
