 ABSTRACT

Seasonal Incidence of fruit borer(Helicoverpa armigera Hubner) of chilli (Capsicum annum L.) was studied during June to December 2014, at Horticulture farm, Rajsthan College of Agriculture, Udaipur.The study revealed that the incidence of fruit borer, H. armigera (1.00 larvae plant-1) was commenced in the fourth week of August (34 SMW) and touched its peak in the first week (40 SMW) of October (2.80 larvae plant-1). The mean atmospheric temperature and relative humidity during the peak incidence were 26.95 °C and 59.55 %, respectively. In 47th SMW, the fruit borer population was 0.40 larvae plant-1 was recorded. The Fruit borer exhibited a negative and significant correlation with relative humidity and total rainfall, while with temperature positively non-significant.
