Abstract : The population fluctuations of Eugnamptus marginellus [Deporaus marginatus] were investigated in relation to major abiotic factors in West Bengal, India, in 1993-95. It was found that leaf damage on mangoes was at a peak during July-August and least during the 2nd fortnight of November, followed by no activity during December-February. Temperature, relative humidity and rainfall all influenced the development of the population.
