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

W. R. Nickle, W. J. Connick, Jr., W. W. Cantelo


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%. Key words: biological control, Diabrotica virgifera virgifera, entomopathogenic nematode, formulation, Leptinotarsa decemlineata, nematode, pesta, Steinernema carpocapsae.
