Efficacy of thirteen isolates of entomopathogenic nematodes (EPNs), 12 of them belongs to Heterorhabditis bacteriophora (H.b) and 1 to Steinernema cubanum (S.c) against neonate larvae of Capnodis carbonaria (C.c) and Capnodis tenebrionis (C.t) were evaluated in laboratory. Three application rates 30, 90 and 270 infective juveniles (IJ) of EPNs per 1ml distilled water for each species of Capnodis were used and replicated 12 times, each replicate contained 3 Capnodis larvae. Results showed that all EPNs isolates had a potential virulence to kill larvae of both species (C.c) and (C.t) 2-3 days after infection. Isolate 12 (H.b) was the most effective where 72%,86% and 94% of (C.c) larvae were killed at 30,90, and 270 IJ/1ml, respectively. Isolate 13 (S.c) was the lowest effective where 19%, 50% and 72% of larvae were killed, respectively. Killing percentage of both (C.c) and (C.t) were close.
