蜡蚧轮枝菌MZ041024菌株对平菇厉眼蕈蚊成虫的毒力测定
Determination on the Virulence of Verticillium lecanii Strain MZ041024 to Adult Lycoriella pleuroti
摘要
Abstract
[Objective] The purpose was to study the pathogenicity of Verticillum lecanii MZ041024 to the adult of Lycoriella plewoti. [Method] With L. pleuroti selected from the fungi bags in the edible fungi cultivation land in Mengzi County as the tested material, the conidium concn. of V. lecanii MZ041024 was set up as 5 treating concn. from 5.0 × 10~4 -5.0 × 10~8 spores/ml to make the determination on the virulence to the adult of L. plewoti in lab. [Result] The virulence of V. lecanii to the adult of L pleuroti was strengthened along with the increase of conidium concn. and the adult of L. pleuroti appeared to be dead from 2nd d, with the mortality rate of adult was 31. 92% , 45. 16% , 62. 25% , 73.03% and 79.78% resp. under 5 conidium concn. from 5.0 × 10~4 -5.0 × 10~8 spores/ml. LC_(50) was 3. 581 × 10~8, 2.451 × 10~7, 4.218 × 10~6 and 2. 648 × 10~5 spores/ml in 4th, 5th, 6th, 7th d resp. LT_(50) of adult under 5 conidium concn. from 5. 0 × 10~4 - 5. 0 × 10~8 spores/ml was shortened along with the increase of conidium concn. and it was shortened from 7. 5 d to 4. 8 d. [Conclusion] V. lecanii MZ041024 had stronger virulence and better control effect on the adult of L. pleuroti in the lab.关键词
