Field biology and sem study of sugarcane wooly aphid, Ceratovacuna lanigera Zehntner

Field biology, morphometrics and SEM study of body parts of sugarcane woolly aphid, Ceratovacuna lanigerum Zehntner are included in this study. Twenty morphological characters were measured. The line diagrams of body, head, abdomen, the arrangement of antennae, rhinaria, wax glands, wax gland plates, spiracles, subanal plate, cauda, frontal horns, wing venation of forewing and hindwing are given.
