[Studies on Paecilomyces muscardine of Cordyceps sinensis host insect].
OBJECTIVE
To Clarify the cause of the disease of Cordyceps sinensis host insect Paecilomyces muscardine.


METHODS
Separately observing eggs, larvals, pupals, adults and their circumstances causing diseases in every stage. Adopting separately Hemolymph, bodies of dead insects and conidiospores; separating and culturing them, them observing and identifying the inoculum. Inoculating healthy larvals from the purely separated and cultured plants of inoculum.


CONCLUSIONS
The original inoculum of the disease is Paecilongces frinoues, which may often be found in the period of larvals and seldom found in the period of pupals but never in that of adults and eggs. The main symptom of larval is dullness and weakness. But the typical Symptom is a layer of a kind of white power of conidiospore on the surface of the dead body which comes into being later stage.
