The present comparative study on relative toxicity of Cypermethrin, Malathion, Methyl Parathion and Monocrotophos to the adults of Dysdercus cingulatus (Fabricius) shows that Methyl Parathion in most effective (LC50 = 0.437) where as Monocrotophos is the least effective. On the basis of LC50 value the order of toxicity in descending manner is Methyl Parathion>Cypermethrin>Malathion>Monocrotophos.

 

Keywords : Insecticides, Cypermethrin, Malathion, Methyl Parathion, Monocrotophos.
