不同环境条件对球孢白僵菌HFW-05的敏感性变化
Sensitivity to Changes of Environmental Factors on Beauveria bassiana HFW-05 Strain
摘要
Abstract
To explore sensitivity changes of HFW-05 strain treated by different temperature and ultraviolet irradiation, the growth and toxicity of the strain under different temperature and UV radiation was studied. Results indicated that germination and sporulation of the strain was appropriate at 25℃ , and the enzyme production could increase at 30℃. The growth rate and sporulation were increased at 35°C with UV radiation under 1 h,but the growth rate would reduce with postponement of the exposure time. The lethal rate of the Plutella xylostella (Linnaeus) was 93. 1% by the treatment of 30℃ ,and it could effectively control the population of insect.关键词
