The rugose spiraling whitefly (RSW), Aleurodicus rugioperculatus was first described by Martin from Belize in Central America in 2004 based on puparium collected from the leaves of coconut. This whitefly was first documented as a pest in Florida in urban landscapes in Miami Dade County in March 2009, but little is known about its biology.The RSW is highly polyphagous with more than 118 hosts belonging to 43 plant families, including several economically important crops in the United States. Division of Plant Industry host record frequency data from 2009 to 2012 proved that 22 % of RSW affected palm species, 16 % gumbo limbo, 10 % on Callophyllum spp., 9 % avocado, 3 % mango and within the Areacaceae (palms), 44% coconut. Initially, this whitefly was observed in several coconut farms in the Pollachi area of Coimbatore district, Tamil Nadu and Palakkad from kerala during July - August 2016. A total of 17 plant species under 11 families were recorded as preferred hosts of A. rugioperculatus. The infestation was found very severe on lower leaves compared to that of the middle and upper young leaves in dwarf and hybrid coconut palms hich are about 4 to 6 years old. The population of nymphs ranged between 18 to 37 nymphs / cm 2 of leaflet. Natural enemies to recorded were RSW viz., Encarsia guadeloupae Viggiani, E. noyesi, Alueroctonus vittatus, Nephaspis oculata. Among these E. guadeloupae potential biocontrol agent against RSW as 50 to 60 % natural parasitization.
