The results indicated that the magnetized water affected the production of submerged conidia. The output of submerged conidia were increased significantly in proper magnetized water medium. In addition, the infectivity of submerged conidia of M337 strain was tested in laboratory. The test showed that there were no significant differences in the toxicity to the 3rd～4th instar larvae of Dendrolimus punctatus between Submerged conidia harvested from medium of magnetized water and those from medium of non\|magnetized water. It is hoped that the results may be used as the basis for the study on large scale of submerged conidia of Metarrhizium anisopliae and Metarrhizium guizhouense cultivated by magnetized water.展开更多
