Response of Steinernema carpocapsae Infective Juveniles to the Plasma of Three Insect Species.
Exsheathed infective juveniles of Steinernema carpocapsae All strain were attracted to the plasma of three species of insects in agar plate bioassays. Plasma of Pieris rapae crucivora, Spodoptera litura, and Agrotis segetum attracted 88.6%, 80.4%, and 64.4%, respectively, of Steinernema carpocapsae juveniles added to plates. Autoclaved plasma of S. litura larvae attracted more juveniles than saline controls, but less than nonautoclaved plasma. The active agent passed through a 14,000 MW dialysis membrane.
