“…They revealed progressive decrement in viral efficiency with prolong sunlight exposure and concluded that Tinopal supplemented was acted as optical brightener that provided excellent protection from sunlight inactivation by enhancing insecticidal properties. However, supplementation of Tween 80 (Polysorbate) provides least protection to virus it might be due to its surfactant nature with fatty acid chain moiety of 15 carbons and negative charge that stimulates the antiviral activity (Prabhu and Mahalingam, 2017). Effect of natural and synthetic additives against UV inactivation of baculoviruses was investigated by Gifani et al (2021).…”

This experimental study evaluated the effect of adjuvant supplementation on larval mortality of nuclear polyhedrosis virus under sunlight. Study revealed that Tinopal @1% provided best protection from sunlight and retained viral efficacy up to 68.75 and 66.75% in SpltNPV (native) and SpltNPV (NIPHM) respectively, against third instar larvae of Spodoptera litura (F). However, all adjutants resulted in significantly higher larval mortality as compared to control (virus alone) under sunlight. SpltNPV viral formulations stored at different storage conditions recorded minimum reduction in larval mortality, when stored in amber coloured glass bottle at refrigeration temperature (4± 2°C).
