Invasion of rugose spiralling whitefly in West Bengal.

Abstract

Recently, occurrence of rugose spiralling whitefly, Aleurodicus rugioperculatus, was noticed in Purba Midnapur and Howrah districts of West Bengal during April 2019 on coconut (Cocos nucifera), banana (Musa spp.), mango (Mangifera indica), sapota (Manilkara zapota), Hibiscus (Hibiscus rosa-sinensis), guava (Psidium guajava), citrus (Citrus spp.), water apple (Syzygium samarangense), Jamun (Syzygium cumini), ficus (Ficus benghalensis), custard apple (Annona spp.), jack fruit (Artocarpus heterophyllus), areca nut (Areca catechu), betel vine (Piper betle), Spanish cherry (Mimusops elengi), akashmoni (Acacia auriculiformis) and areca palm (Dypsis lutescens). This is thought to be the first report of this pest from West Bengal. This paper describes its distribution, severity, host range, natural enemies, integrated management strategies, and impact on coconut cultivation in India. In India, the pest was found to feed on 35 host plants across the field, horticultural, plantation and ornamental plants. The pest is believed to be originated from Central America and could be introduced to India accidentally from Florida, USA, through ornamental plants trade from the region.
