Studies on the Growth Conditions for Paecilomyces griseoviride Strain U-2 and Its Ability to Infect Aphids

摘要

The growth of Paecilomyces griseoviride U-2 strain in different cultures and the effects of temperature, pH, humidity on growth and utilization of carbon and nitrogen sources were reported in this paper. The results of bioassay showed that the cinidiosphore of U-2 strain has infectious activity to aphids (vegetable aphids) and its fermentation liquid (from centrifuging) also has a certain aphid -killing activity.
