abstract
Study was conducted on wild grown milkweed (Calotropis gigantea (L.) W. T. Aiton) during 2016 in various localities of Punjab, India. Infestation of Aphis nerii Boyer de Fonscolombe was recorded on C. gigantea. Discoloured spot on leaves and sooty mould development on honeydew was observed on C. gigantea. Body of this aphid is yellowish to dark yellow in colour with uniquely black legs, antennae, siphunculi and cauda. Earlier, Aphis nerii was not reported from Punjab. So, the present study is the first report of Aphis nerii on any crop from Punjab, India.
