Beauveria Endophytes Can Curb Grasshopper Pests

Beauveria bassiana effect on insects

By Andrew Porterfield Grasshopper species, including Dichroplus maculipennis, are common insect pests. They have been known to cause widespread damage to crops such as corn, soybeans, and wheat, by devouring the leaves and stems of targeted plants. The only means of controlling D. maculipennis so far is with chemical pesticides, which can have environmental consequences. […]
