- Abstract
Spodoptera litura along with other core insects is a premeditated severe pest of sugar beet. S. litura can damage crop completely at 125 days after sowing and causes physiological spoiling in economical part and crown rot. Development of eco-friendly management practices to obtain sustained crop yields over a long period is highly essential. It is essential to evaluate all the IPM tools to reduce S. litura incidence in commercial cultivation of sugar beet crops. Present study suggested that earliest incidence of S. litura seen during last week of 4th month after sowing and remain continuously vigorous nearly maturity stage. S. litura damage sugar beet crop during March to May but no damage found during January to first fortnight of February. During study it was found that S. litura infant larvae defoliate the total crop. Late harvesting of the crops was severely damaged by Spodoptera than the right time of the harvest in all the tested entries. Resistance has been developed by S. litura against all know chemical insecticide due to continuous application. So, novel insecticides are much needed to control S. liturato prevent an increasing pest population from reaching the ETL.
