Field longevity studies of pheromone lure of brinjal shoot and fruit borer (Leucinodes orbonalis Guenee) in relation to weather parameters

Abstract

An experiment was conducted at farmers field of simikeri, bagalkot district during 6th February to 6th april, 2013 to assess the field longevity of pheromone lures in relation with weather parameters. It revealed that after 2 months of exposure of lure in the field, the left over pheromone quantity observed was 1.55mg. The maxi mum and minimum temperature showed non-signifcant negative relationship with male moth catches. Morning and afternoon relative humidity had negative relationships with brinjal shoot & fruit borer moth catches and rainfall had non significant positive relationship with male moth catches, whereas, wind speed showed negative relationship with brinjal shoot and fruit borer.
