laboratory studies on australian isolates of metarhizium anisopliae as a biopesticide for the cattle tick boophilus microplus. | thirty-one isolates of metarhizium anisopliae were bioassayed against the cattle tick (boophilus microplus). more than half of the isolates showed a high degree of virulence to ticks. radial growth curves for growth between 20 degrees c and 40 degrees c were obtained for all isolates. this information together with information on virulence will be important for the selection of isolates suitable to kill ticks on the surface of cattle. a biopesticide for cattle ticks must kill ticks rapidly at te ... | 2008 | 17764687 |
