The scarab beetle, Temnorhynchus baal(Reiche & Saulcy) (Coleoptera: Scarabaeidae), becomes a key pest of strawberry, especially after increasing its cultivated area and economic importance in Egypt. Few entomopathogenic nematode (EPN) species/strains were tested against this pest, where only a foreign species had good effect comparable to the native populations tested previously. Thirty-eight indigenous Heterorhabditis indicapopulations were tested against the most damaging, third instar larvae of H. baalin two soil types, where strawberry cultivation prevails. The corrected mortality induced by indigenous H. indicapopulation in T. baallarvae was (99.52 and 98.57%) for 15 populations in the sandy soil and 23 in loamy sand soil, respectively. Overall average of infective juveniles (IJs) per T. baallarva was about (41,000). The average of emerged nematode-IJs from the infected grubs for the 15 EPN populations in sandy soil, (46,960 IJs/grub), was significantly (P< 0.001) higher than that (36,502 IJs/grub) of 23 EPN populations in loamy sand soil. The insignificant difference was detected in the reproductive capacity among nematode populations in T. baallarvae in sandy or loamy sand soil. A highly significant difference was found among total IJ numbers collected 10, 18, 26, and 30 days post-inoculation in sandy or loamy sand soil. The persistence of the H. indicapopulations in the soil varied greatly. Obtained results suggest further use of at least ten populations of such indigenous nematodes under field conditions.
