Joint action of Beauveria bassiana and the insect growth regulators diflubenzuron and novaluron, on the migratory locust, Locusta migratoria
Journal of Pest Science 86 (2), 293-300
Abstract: Beauveria bassiana (Balsamo) Vuillemin and sublethal concentrations of the insect growth regulators (IGR) diflubenzuron and novaluron were applied simultaneously and sequentially to second-instar Locusta migratoria migratorioides (Sauss.) to determine the interaction between these materials and an entomopathogenic fungus. Nymphs were fed on corn leaf disks treated with several concentrations of each IGR, and a constant dose of B. bassiana was applied topically. Additive interaction was demonstrated in all instances when second-instar nymphs were exposed to diflubenzuron or novaluron simultaneously with B. bassiana treatment, and when the fungus was applied first and IGR after 48 h. Additive interaction was also exhibited when novaluron was applied first and B. bassiana after 48 h. Antagonism was demonstrated when nymphs were fed diflubenzuron-treated corn leaves first, then after 48 h were treated with B. bassiana. The additive interaction that was observed in our experiments could still be useful to achieve efficacious levels of acridid control at low rates of an IGR along with a biological control agent such as an entomopathogenic fungus.
