Effects of Pesta-Pelletized Steinernema carpocapsae (All) on Western Corn Rootworms and Colorado Potato Beetles

Pesta-pelletized Steinernema carpocapsae (All) nematodes were used in soil treatments in the greenhouse against larvae of Western corn rootworm and prepupae of Colorado potato beetle. The pesta-pellets delivered 100,000 living nematodes/g. Infective-stage nematodes and their associated bacteria survived the pesta-pellet process, emerged from the pellets in large numbers in the soil, and reduced adult emergence of both pest insects by more than 90%.
