agricultural and horticultural crops all over the world including Pakistan. Insecticides have
been widely used against different instar larvae of S. litura to minimize the pest population on
various crops. New chemistry insecticides were tested to check their toxicity against S. litura
on cabbage under laboratory conditions during 2019. Emamectin benzoate was highly toxic
followed by chlorantraniliprole, flubendiamide and fipronil. LC50 and LC 90 values of
emamectin benzoate were 30.54, 19.73 ppm and 459.07 and 275.65ppm after 24 and 48 h,
respectively. 100% mortality of larvae was recorded at all concentrations of emamectin
benzoate after 72 h of treatment. The lethal concentration, 50 % (LC50) values of
chlorantraniliprole after 24, 48 and 72 h were 47.03, 32.49 and 17.58 ppm, respectively.
Chlorantraniliprole was found to be extra lethal insecticide than flubendiamide and fipronil.
Both (LC50 and LC90) values of fipronil after 24, 48 and 72 h were 55.76, 46.26, 28.47, and
801.03, 647.27, 510.44 ppm respectively. The results concluded that emamectin benzoate has
potential to be used in integrated pest management strategies to significantly reduce the pest
population.
