Spiralling whitefly, Aleurodicus dispersus Russell, a polyphagous pest native to the Caribbean region and Central America has turned out to be cosmopolitan as well creating havoc to the farming community. The peculiar egg-laying pattern of this pest has given its name spiralling whitefly. The insect has four nymphal stages and has a pupal period of 2-3 days, thereby the total developmental period is of 18 to 23 days. It has been found that high temperature and high relative humidity during summer has a positive impact on pest incidence. As their body is covered with a heavy waxy material, management of this pest is quite a task. Since A. dispersus is an exotic pest in most of the countries, hence classical biological control through the introduction of natural enemies from the area of origin of the pest is considered as a sustainable management option. The natural enemies chiefly the parasitoids Encarsia guadeloupae Viggiani and Encarsia haitiensis Dozier has turned out to be a promising tool in suppressing the menace of spiralling whitefly.
