Author(s): Virendra, AS Thakur, M Thomas, Shailendra Kumar and Narayan Lal

Abstract:
Population fluctuation of P. pulverea and E. amabilis were recorded under storage structures. The mean monthly population (larvae + pupae) of P. pulverea and E. amabilis at its peak were (16.33) and (15.33) in month of December and November 2015, respectively. High populations of these pests were found in kuchcha storage structures. The adult of P. pulverea and E. amabilis emerged from the stored lac samples were recorded. The adult of P. pulverea are generally small to medium size, dull-blackish patterned moths while the adult of E. amabilis is generally white-pinkish in colour. The adult emergence (%) of P. pulvereawas highest (81.99 %) from the October 2015 lac samples while in case of E. amabilisitwas highest (80.18 %) in the August 2015. There was no emergence of adult of these pests from the lac samples collected in the months of September 2015, January and February 2016. The mean population of P. pulverea was highest (16.33) in Kuchcha storage and lowest (6.00) in Pucca storage. The mean population of P. pulverea was highest (12.67) among Small traders and lowest (6.67) in Big traders. The mean population of E. amabilis was highest (15.33) in Kuchcha storage and lowest (6.67) in Pucca storage. The mean population of E. amabilis was highest (12.00) among Small traders and lowest (7.00) in big traders.
