Abstract

The study records a new host, the jungle fire plant, Excoecaria cochinchinensis Lour. (Euphorbiaceae) for Conchaspis angraeci Cockerell (Hemiptera, Conchaspididae) in India from Kerala. E. cochinchinensis is a popular foliage ornamental plant with vibrant red and green coloration, which was observed with severe infestation of C. angraeci popularly known as common false armored scale. Infestation leads to yellowing, wilting and defoliation, thereby reducing the economic value.
