Monitoring of okra shoot and fruit borer (Earias vittella) fabricius through pheromone traps and the impact of abiotic factors on trap catch
SK Mohanty, A Mohanty and S Srichandan
Seasonal incidence of Okra Shoot and Fruit borer, Earias vittella Fabricius was studied from the pheromone trap catches during Summer 2013 and 2014 in Balasore district of Odisha. The adult moth was first appeared during 10th and 11th Standard Meteorological Week (SMW) in two years of study respectively. The correlation study between abiotic factors and pheromone catch of the adult male population revealed a significant positive correlation with temperature (maximum, minimum, average) and a negative correlation with relative humidity (morning, afternoon and average) and rainfall. The extent of fluctuation in trapped adult male population due to multiple interactions of abiotic factors was 85.4% during 2013 and 89.9% during 2014. Among the independent environmental variables temperatures played the dominant role followed by relative humidity in adult population variation.
