First Report of Encarsia dispersa Polaszek (Hymenoptera:Aphelinidae) as a Parasitoid of Rugose Spiralling Whitefly, Aleurodicus rugioperculatus Martin (Hemiptera: Aleyrodidae), A Recent Invasive Pest in India, with Notes on its Predators

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.

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.
