abstract
The study was undertaken on Leaf roller, Argyroploce leucaspis larval behavioral at laboratory condition during year 2015 and 2016 at RMD College of Agriculture and Research Station, Ambikapur, Surguja Chhattisgarh. Leaf roller, Argyroploce leucaspis larva completed its development in five instars. Fifth instar larva occupied more time to convert into pre pupal stage (4.63 days) of larval length, weight and percent leaf damage was also highest in fifth instar larvae of 11.27 mm, 25.08 mg and 78.01 percent respectively. Third instar larvae started rolling the leaves with silk threads. Rolls were constructed and occupied by one or more larvae. The larvae matured up to fifth instar and completed pre pupal and pupal stage inside the leaf roll.
