Abstract
AbstractThe susceptibility of 31 species of agricultural insect pests representing 7 families of Lepidoptera, 3 of Diptera, and 3 of Coleoptera to the entomogenous nematodesSteinernema feltiaeFilipjev andHeterorhabditis bacteriophoraPoinar, were investigated in the laboratory. Of the 27 species found susceptible toS. feltiae, 19 are reported for the first time. Of the 21 species killed byH. bacteriophora, 15 are reported for the first time. The Lepidoptera as a group were highly susceptible to the nematodes. On the basis of larval mortality caused by the nematodes, of nematode reproduction in insect cadavers, and of the known economic importance and life histories of the test insects,S. feltiaewas judged to warrant further research as a possible biological-control agent againstEuxoa ochrogaster(Guenée),E. auxiliaris(Grote),Agrotis orthogonia(Morr.),Actebia fennica(Tauscher),Mamestra configurataWalker,Delia radicum(L.),D. antiqua(Meig.), andZygogramma exclamationis(F.).
