ABSTRACT
With the objective to find out the most harmful and injurious mite pests occurring on fruit trees, surveys were made throughout the different districts of South Bengal and Panonychus citri (McGregor) commonly known as citrus red mite, appeared to be the major pest of Papaya and showed different degrees of damage symptoms. Hence, a biochemical component study was undertaken to examine the extent of damage done by this mite. Different minerals, inorganic and organic compounds were taken into consideration for experiments and they were examined according to the standard methodologies. The result revealed huge mechanical damage and depletion in amount of chlorophyll a and chlorophyll b (76.47% and 77.93% respectively). The nitrates and nitrites were also damaged by considerable amount (61.53% and 70.93% respectively). Among the minerals, Calcium and Magnesium were affected with the percentage of depletion of 36.12% and 35.83% respectively. Depletion in case of Total Protein and Carbohydrate were 26.01% and 48.73% respectively.
