Abstract:
The fungus Verticillium lecanii was assessed for entomopathogenicity against nymphal Bemisia tabaci in an environmental chamber and in a greenhouse mist chamber on the host Euphorbia pulcherima. Proportional mortality of Bemisia nymphs due to fungal exposure were; in the environmental chamber 89-96%, and in the mist chamber 61-89%. Two fungal characteristics, hyphae growth and sporulation, were used as parameters for augmentation experiments. Response to particular honeydew constituents, glutamine, glutamic acid, serine and sucrose in concentrations ranging 500-40,000 ppm were measured. Hyphae growth, in comparison to water agar (1.26-1.52 mm/24 h), was inhibited by all substrates at all concentrations (0.82-1.47 mm/24 h). Sporulation was enhanced at higher concentrations, 17.0-117.0 (x10⁴) spores produced, in comparison with water agar, 10.2-15.5 (x10⁴) spores produced.
