Insecticidal impact on the post-embryonic development of Rhynocoris kumarii Ambrose and Livingstone (Het., Reduviidae)

The impact of sublethal concentration of five insecticides namely monocroto phos, dimethoate, methylparathion, quinalphos and endosulfan on the post-em bryonic developmental characteristics such as stadial period, body weight, fecundity and longevity of Rhynocoris kumarii was studied. All of the insec ticides except endosulfan increased stadial period, decreased body weight, fecundity and longevity.
