Shivamogga region is one of the richest sources of biodiversity in the world, having a wide range of medicinal and aromatic plants. The present studies were undertaken to record the incidence of fruit borer Helicoverpa armigera on Ashwagandha. Fruit borer, Helicoverpa armigera (H.) (Noctuidae: Lepidoptera) is one of the pest of ashwagandha in Shivamogga. Its incidence in cultivated ashwagandha during 2014-2015 was studied at Organic Farming Research Center (OFRC) Shivamogga. The larval incidence and per cent fruit borer damage on ashwagandha at OFRC, Shivamogga was recorded during September 2014 to February 2015 and its occurrence was peak during third week of December i.e., 1.3 larvae per plant and 41.40 per cent respectively. A non-significant correlation was observed between the larval population of H. armigera and weather factors. The correlation between fruit damage and weather factor was found negatively significant to rainfall and non-significant to temperature and relative humidity.
