AB  - Scale insects are serious pests of mango (Mangifera indica) in many mango-producing countries of the world, including Ethiopia. Among the many scale insects, the white mango scale, Aulacaspis tubercularis Newstead (Homoptera: Diaspididae), is a key insect pest of mango causing devastating losses. The current experiment was conducted to study the host preference of A. tubercularis to different mango cultivars grown at Raj Agro Industry Loko Mango Commercial Farm (RAILMCF) in the East Wollega and Melkasa Agricultural Research Center (MARC) mango orchards in the East Shewa zones.
