Abstract
Spodoptera frugiperda Smith, 1797 (Lepidoptera: Noctuidae) is commonly known as fall
armyworm or FAW. It affects more than 300 crops including maize, sorghum,
sugarcane, paddy, spinach, potato, castor, and chickpea where maize is being
attacked the most (Montezano et al., 2018) [7]. This insect
pest has been causing severe loss to crops since its first invasion in India
(Deshmukh et al., 2018) [3]. Various classes of Insecticides
like organophosphates carbamates and synthetic pyrethroids are being used by
the farmers in the agricultural fields to control the pest but in vain. Hence,
a new insecticide, a diamide: chlorantraniliprole was chosen for laboratory testing
against S. frugiperda. Insect pest was brought from fields and reared in
the lab for multiple generations to create a pure breed and study the
pesticide-resistance development in insects if any. Laboratory rearing
of S. frugiperda was done on a chickpea-based artificial diet. The LC50
was achieved at a concentration of 0.05 ppm in the first three generations of
testing on larval instars whereas, in the fourth generation, LC50 was achieved
at 0.5 ppm. The effectiveness however reduced after three generations. The
present work highlights that; the diamide Chlorantraniliprole is effectively
controlling the population of S. frugiperda from generations 1 to 3 and
can be recommended to the farmers. At the same time, overuse of
Chlorantraniliprole cannot be advocated as, in Generation 4 perishability
decreases leading to the development of resistance against Chlorantraniliprole
in S. frugiperda.
