Abstract

Studies were carried out during 2021-2022 to evaluate toxicity levels of different insecticides against larvae of bamboo leaf roller Pyrausta coclesalis (Pyraustidae: Lepidoptera) are one of the most important group of leaf feeders on bamboo (Family: Poaceae) in Central India. Spinosad 45 SC (0.03%), Profenofos 50 EC (0.04%), Cypermethrin 25 EC (0.03%), Fenvalerate 20 EC (0.03%), Chlorantraniliprole 18.5 SC (0.03%) and bio pesticide Azadiractin 10000 PPM (0.05%) at the recommended concentration was evaluated against of bamboo leaf roller at the Division of Forest Protection, Tropical Forest Research Institute, Jabalpur, Madhya Pradesh, India. The study revealed that Spinosad 45 SC (0.03%), Profenofos 50 EC (0.03%) and Cypermethrin 25 EC (0.03%) were effective with the maximum larval mortality of 91.66, 83.33 and 75 percent at 72 hours after treatment followed by Fenvalerate 20 EC (0.03%) and Chlorantraniliprole 18.5 SC (0.03%) which recorded similar mortality of 66.66 were at par to each other at the same period of observation. Among bio pesticide Azadiractin (0.05%) treatment recorded least larval mortality of leaf roller 58.33 percent at 72 hours after treatment.

Conclusion

The data on percent mortality after 72 hours of exposure showed that the chemical pesticide showed not only significant but superior results over control. Therefore it is suggested that the population of bamboo leaf roller larvae can be checked by spraying chemical insecticides viz., Spinosad 45 SC (0.03%), Profenofos 50 EC (0.03%) and Cypermethrin 25 EC (0.03%) are effective pesticides against bamboo leaf roller and can act as better tools in insect pest management for leaf roller menace in bamboo nursery and young plantations.
