异带属绦虫两新种(圆叶目:囊宫科)

The Methods for Examination of Quality of Paecilomyces lilacinus Production Determination for the Colony forming Unit

记述两种异带属绦虫新种：林鹬异带绦虫和矶鹜异带绦虫．对新种和形态作了较详细的描述，并与相似种类进行了图、表比较．

The Paecilomyces lilacinus produced has biological control effects against nematodes parasitizing on many plants.The methods of examining its quality were studied. In view of absence of a quality control standard in China,the colony forming units (CFU) were proposed as one of the most important parameters of the product′s quality, and was determined by the dilution plate method. The examination of 10 batches of specimens prepared demonstrated that the parameters 3.5×10 6 CFU/g specimen could reflect the product′s quality, which is also in accordance with the technological requirements and peasant′s demands.Therefore,it was recommended as an industrial standard of Paecilomyces lilacinus production.
