The field experiments were carried out during Kharif 2017-18 at Hittinahalli village near the College of Agriculture, Vijayapura. The contemporary research unveiled that peak moth activity was observed during the II week of December (47th standard meteorological week) (52.78 moths / trap / night). Later on, the trap catches declined gradually with a minimum trap catch of 12.50 moths / trap / night. The rosette flowers were ranged from (2.25 to 15.45%) with seasonal mean of (9.05 %). While the incidence in green bolls was noticed from the first fortnight of September (34th SMW) and rose gradually to reach its zenith during the second fortnight of December (48th SMW). The larval incidence ranged from (9.00 to 51.00 larvae/50 bolls) with a mean of (34.75 larvae /50 bolls) and the green boll damage ranged from (7.60 to 42.21 %) with mean of (30.52 %). Moreover, open boll damage was ranged from (48.36 to 53.48 %) with a mean of (53.45 %) during the cropping season. Furthermore, locule damage ranged from (24.71 to 39.35 %) with a mean of (39.05 %). The trap catches had a negative and non-significant relationship with rainfall and a negative and significant relationship with maximum temperature.
