Screening of Some Mycoinsecticides for the Managing Hairy Caterpillar, Pericallia ricini Fab. (Lepidoptera: Arctiidae) in Castor

K. Sahayaraj and J. Francis Borgio

Abstract:
The effectiveness of oil-based conidia formulation of three indigenous fungal isolates such as Beauveria bassiana (Balsamo) Vaillemin, Verticillium lecanii (Zimm). Viegas and Paecilomyces fumosoroseus (Wize) Brown et Smith (Deuteromycotina: Hyphomycetes) were evaluated against fourth instar larvae of Pericallia ricini Fab. (Lepidoptera: Arctiidae) under laboratory conditions by dermal toxicity test. All the three isolates were pathogenic to P. ricini at all tested concentrations. Among the three isolates, P. fumosoroseus caused lowest mortality (21.67% at 2.7x109 spores mL-1), followed by B. bassiana (57.33% at 4.1x109 spores mL-1) and V. lecanii caused highest (97.33% at 3.9x109 spores mL-1). LC50 values at 96 h was calculated as 9.6x108, 1.3x108 and 2.36x1011 conidia mL-1 for B. bassiana, V. lecanii and P. fumosoroseus respectively. Hence, oil-based formulation of V. lecanii can be important castor pest P. ricini.
