The present investigation entitled “Seasonal incidence fruit borer, Helicoverpa armigera (Hubner) (Lepidoptera: Noctuidae) infesting tomato†was carried out during rabi season in 2015-16 at the Central Experimental Station, Wakawali, Dist.-Ratnagiri. The study revealed that there were marked differences in fruit borer infestation as regard Standard Meteorological Weeks. The initiation of pest incidence was found in the first week of January. During the cropping season the fruit damage varied from 7.88 to 42.83 percent on a number basis. Minimum (7.88%) fruit borer infestation was recorded in 14th SMW (2-8 April), while maximum (42.83%) fruit borer infestation was recorded during 11th SMW (12-18 March). It was evident from the results that tomato fruit borer, H. armigera incidence increased gradually with the advancement of the cropping season.
