摘要：

Differences were observed in the pathogenicities of two strains of Verticillium lecanii (strain numbers 1.72 and 19.79) to the whitefly Trialeurodes vaporariorum and the aphid Macrosiphoniella sanborni. The mean pathogenicity of a mixture of the two strains was intermediate to that of the individual strains, attributable to a competitive interaction during infection. Differences between strains were observed in the production of conidia in vitro and on host insect cadavers. When hosts were infected with the dual-strain suspension, conidia of strain 19.79 only were recovered from T. vaporariorum whereas conidia from both strains were recovered from M. sanborni.
