Abstract
A field experiment was conducted during 2014-15 in kharif and rabi season at GKVK and IIHR, Bengaluru, to document the population estimation and seasonal incidence of fruit borers viz., Helicovarpa armigera (Hubner), Diaphania indica (Saunder) and Bactrocera cucurbitae (Coquillet) on bitter gourd (Momordica charantia L.). Outcome of the study yielded, fruit infestation of fruit fly was more (40.07 & 30.57), followed by pumpkin caterpillar (5.85 & 3.20) and American bollworm was (1.88 & 1.95) in both kharif and rabi season, respectively. Fruit fly fruit infestation was peak during last week of September (52 %) and in last week of February (33 %). Incidence of fruit fly in kharif recorded significant positive correlation with rainfall (r = 0.71) and positively correlated with maximum temperature (r = 0.35) and maximum RH (r = 0.59). During rabi, significant positive correlation with maximum temperature (r = 0.76). Multiple linear regression suggests that incidence of fruit fly on bitter gourd was influenced by 51 per cent by rainfall during kharif and 59 per cent by maximum temperature during rabi.
