Abstract

Incidence of Spodoptera litura in terms of larval population showed non-significant relationship with maximum temperature, relative humidity, wind speed, spiders and coccinelIid predatory beetles, but significant relationship with minimum temperature. The results of chemical control trials indicated that emamectin benzoate 0.00725% + was the most effective treatment followed by indoxacarb 0.0145% and indoxacarb 0.00725%+ novaluron. 0.005% in reducing the larval population of S. litura.
