Abstract

Rugose Spiralling Whitefly (RSW), Aleurodicus rugioperculatus Martin initially described from Belize. It is a tiny, sap-sucking, phloem feeder that is polyphagous. A review was conducted on sustainable and effective alternative techniques to pest management. Under biological management, coconut orchards sprayed twice with an introduction release of the parasitoid Encarsia guadeloupae, and twice with Isaria fumosorosea fungus (NBAIR-Pfu-5) @ 5 g/lt with sticker @ 10 g/lit, saw a substantial reduction in rugose spiralling whiteflies. In Karnataka, natural parasitism ranged from 7 to 80%, and the parasitoid Encarsia guadeloupae was identified as the main parasitoid linked to the pest. It was discovered that extensive infestations were more common in dwarf coconut types and hybrids than in tall kinds. The application of eco-friendly integrated pest management practices, such as light traps, yellow sticky traps, jet water spray, 0.5% neem oil, and the parasitization of Encarsia guadeloupae puparia on palm leaflets, significantly decreased both the incidence and intensity of the disease. The most successful method for lowering the RSW population on coconut was to spray Isaria fumosorosea (5 ml/l) and profenophos 50 EC (2 ml/l) twice at intervals of 15 days

Conclusion

Systemic insecticides can be used to control rugose spiralling whiteflies, but they should only be used as a last resort because they can destroy the biological control agents. To discover the pest early and promote the natural parasitoid Encarsia guadeloupae, periodic surveys and monitoring should be carried out. Yellow sticky traps can be used to control the rugose spiralling whitefly. Apart from the entomopathogenic fungus, Isaria fumosorosea exhibits remarkable efficacy in controlling pests
