Influence of Weather Parameters on Pheromone Traps Catches of Spodopteralitura Febr

A study on influence of weather parameters on Spodoptera litura moth trapping pattern based on pheromone trap catch was carried out at Institute of Forest Productivity, Ranchi, (Jharkhand) during 2010-11 to 2011-12. During the year 2010-11,highest 76.00 moths/trap and in 2011-12 160.00 moth /trap were trapped in the month of July. Weather parameters viz. temperature and relative humidity was positively correlated with the moth trapping pattern. Rainfall negatively effects to Spodoptera. Lituramoth trapping during both the years
