Studies on the evaluation of biopesticides viz., Beauveria bassiana, Isaria fumosorosea NBAIR pfu- 5,Metarhizium anisopliae, Lecanicillium lecanii, Azadirachtin 10000 ppm, soapnut along with jet water spraywere undertakenat SKPP Horticultural Polytechnic College, Ramachandrapuram and Horticultural Research Station (HRS), Ambajipeta. Andhra Pradesh during 2020-21 and 2021-22 with an objective of examining their impact onthe management of rugose spiraling whitefly (RSW). Aleurodicus rugioperculetus Martin in coconut (Cocos nucifera L.) palms variety East Coast Tall (ECT). The overall and pooled results during the seasons 2020-21 and 2021-22, revealed that, Azadirachtin 10000 ppm @ 1 ml/l had recorded with lowest number of RSW nymphs per leaflet and I. fumosorosea NBAIR pfu-5 @ 5 g/l (T₂) recorded with lowest number of adults, incidence and intensity under high incidence (> 20 spirals per leaflet) of RSW. The natural enemies mainly predators viz., spiderswere documented during the study.
