Abstract:
Laboratory experiments was carried out in the Department of Entomology, Institute of Agricultural Sciences, SOADU during 2017-2018. Correlation between weather parameters and biological parameters indicated highly significant correlation between maximum temperature, minimum temperatures, humidity and rainfall with the biology of Leucinodes orbonalis in brinjal. The experiment was laid out in a Complete Randomized Block Design. The incubation period was highest with (6.7 days) during December to January in 2016 and lowest incubation period of (4.0 days) during May to June 2015. The total larval period ranged between a minimum of 13.40 days in May-June to a maximum of 16.80days in December-January. Adult longevity and fecundity of L. orbonalis revealed that males live for a maximum of 4.9±0.1 days whereas the shortest longevity of males was found in the month of May-June (1.6±0.2) days. Accordingly the total longevity was longest (7.1±0.1) days was in December- January and the shortest one (3.2±0.5) was found in May-June.
