Abstract

Encarsia dispersa Polaszek (Hymenoptera: Aphelinidae), an exotic parasitoid fortuitously introduced in India in the late 1990s along with spiralling whitefly, Aleurodicus dispersus Russell (Hemiptera: Aleyrodidae), is reported here as a parasitoid of the rugose spiralling whitefly, Aleurodicus rugioperculatus Martin, a recent invasive pest in India. This is the first report of this host association for E. dispersa , a parasitoid of many species of Aleurodicus in its native geographic range. This marks the reappearance of E. dispersa in South India more than a decade after its total displacement by E. guadeloupae . Predators of the rugose spiralling whitefly observed on banana in Tamil Nadu and Kerala are also listed.
