Among hosts are fruits (including citrus), castorbean, soybean, corn, sorghum, cotton, chestnut, pine and teak. Life History and Habits: This pest breeds throughout the year in India and parts of Australia. The small, oval eggs are laid on or near fruit or seeds of hosts. Larvae feed on or in seed, seed capsules or young shoots. In Australia the larvae mature in approximately 3 weeks in summer and pupation lasts for 2 to 3 weeks; however in winter pupation may be prolonged to eight weeks or more. In severe attacks on sorghum in Australia, plant heads touching each other are bound to- gether in a tight mass of webbing. The pest also bores into and tunnels the stalk, although this type of damage is less common in grain sorghum than in corn. Description: The adult is conspicuous having orange wings with numerous black spots and a wing expanse of approximately 25 mm. Full-grown larva is 15 to 25 mm. long, rather stout, pale or reddish brown with numerous flattened horny warts from which arise short bristly hairs; head red-brown, prothoracic shield large. The pupa is brown and about 11 mm. long and is enclosed by a white silken cocoon. (Prepared in Plant Pest Survey Section in cooperation with other ARS agencies.) CEIR 7(34) 8-23-57 \ %i^j.*y.
