The striped cucumber beetle is the main pest of crops in the cucumber family. Apart from feeding on foliage, it is a vector of bacterial wilt, a disease that can kill the plants. Striped cucumber beetle abundance, bacterial wilt incidence, plant mortality, and yield on plots seeded with spaghetti squash sprayed with BioCérès were evaluated and compared to data from control plots. In summer 2015, the following bioinsecticides were tested: BioCérès by Anatis Bioprotection and Grandevo® and Venerate™ by Marrone Bio Innovations.
