like fruitbody the size of fruitbody is 1 0 u02dc 2 0 cm and white powder like conidia are present countlessly on a fruit portion fig6 paecilomyces sp can be cultivated artificially using silkworm as a host insect therefore the cultivation of paecilomyces sp will be illustrated in more detail by the following description first paecilomyces sp is inoculated into the epidermis of silkworm by spraying a dilution of its spores the dilution is prepared by incubating spores of paecilomyces sp on uncleaned rice medium and then diluting with water to a concentration of 10 7 u02dc 10 8 spores ml then inoculation is preformed into larva epidermis of 4th u02dc 5th instar of silkworm at a temperature 26 u02dc 30 u00b0 c and a humidity of about 90 or more particularly about 90 for 15 u02dc 24 hours after inoculation the infected silkworm is reared under a standard condition such as temperature and humidity according to the conventional method for instance with feeding mulberry tree leaves to it 2nd u02dc 4th in a one day after 15 days the infected silkworm is transformed into hardened pupa whose interior is full of the white spawn the hardened pupa is maintained at a temperature of 15 u02dc 30 u00b0 c and a humidity of about 90 or more particularly about 90 for inducing of fruitbodies after 1 u02dc 5 days the light white spawn is appeared on the epidermis of pupa and after further 1 u02dc 5 days the fruitbodies start to be induced after further 30 u02dc 40.
