Pyrilla perpusilla, commonly known as the sugarcane planthopper,[1] is a planthopper in the family Lophopidae. It is native to Asia where it feeds on grasses and other plants and is a major pest of sugarcane and sorghum.[2]
Description
The adult P. perpusilla has an elongated snout with piercing and sucking mouthparts, and a soft body, and is a yellowish-brown colour. Males have a wing-span of about 20 mm (0.8 in) and females are slightly smaller, averaging 17 mm (0.7 in). The eggs are ovoid, white to yellowish-green and about 2 mm (0.08 in) long. The nymphs are creamy-white and each instar stage has long filaments projecting near the anus.[3]
Distribution
P. perpusilla is native to southern Asia and occurs in Afghanistan, Bangladesh, Cambodia, China, India, Indonesia, Laos, Myanmar, Nepal, Pakistan, Sri Lanka, Thailand and Vietnam.[1]
Hosts
Besides sugarcane, this planthopper has been found feeding on other host plants, and breeding on some of them. These include maize, sorghum, pearl millet, barley, bitter melon, okra, Vietnamese luffa, watermelon, squash, rice, wild oat, pea and Indian thorny bamboo.[4]
Life cycle
Adult female P. perpusilla lay small batches of eggs on sugarcane leaves, mostly on the underside but sometimes on the upper surface, and during the winter, inside the leaf sheath. The eggs are laid in four or five rows and are protected with filaments of whitish wax protruded by the female. They hatch after six to thirty days depending on the time of year.[3] The nymphs pass through five developmental stages, before moulting for a last time and becoming adult. Breeding commences eight or more days later. In Sri Lanka, fecundity in the female is about 133; females live longer than males but there is no overlap of generations because the longevity of the adults is less than the time taken for the nymphs to develop. In India, fecundity ranges up to 880, and the lifespan ranges from 14 to 200 days depending on climatological conditions.[3]
