Abstract

The effect of infection by Pandora neoaphidis and Beauveria bassiana on the reproductive potential of the pea aphid, Acyrthosiphon pisum, and their progeny was assessed. Infection by either P. neoaphidis or B. bassiana reduced the number of nymphs produced within 24 h of inoculation and over the entire infection period compared to uninfected aphids. However, infection by either P. neoaphidis or B. bassiana for 24 or 72 h did not alter the intrinsic rate of increase of the host aphid's progeny. Therefore, fungal infection appears to have no indirect effects on the fitness of the host's progeny.
