The green peach aphid, Myzus persicae, and the melon aphid, Aphis gossypii, are common pests of a number of important greenhouse crops. Virulence of several isolates of hyphomycete entomopathogenic fungi against adult and nymphal stages of both species was evaluated in a series of multiple dose bioassays. Mortality, time to death and impact on adult fecundity were measured and compared to that of commercially-available strains of the fungi Beauveria bassiana, Paecilomyces fumosoroseus and Lecanicillium (=Verticillium) spp. Implications for biological control are discussed.



Species 1: Homoptera Aphididae Myzus persicae (green peach aphid)
Species 2: Homoptera Aphididae Aphis gossypii (melon aphid, cotton aphid)
Keywords: biological control, entomopathogenic fungi
