Özet

The insecticidal effect of native entomopathogenic nematode (EPN) isolates (Steinernema feltiae UTP-5 isolate, Heterorhabditis bacteriophora UMK-7 isolate, S. feltiae DDKY-11 isolate and H. bacteriophora AVB-15 isolate) recovered from the Cappadocia Region of Turkey were investigated on the adults of S. granarius and R. dominica and the larvae of E. kuehniella at different temperatures (15 degrees C, 20 degrees C and 25 degrees C) and concentrations (250, 500 and 1000 IJs/adult for S. granarius and R. dominica; 10, 50 and 100 IJs/larvae for E. kuehniella) under controlled conditions. Insect mortality was recorded after 4th, 6th and 8th day of exposure time for S. granarius and R. dominica, and 2nd and 4th day for E. kuehniella. The results showed that the efficacy of the isolates at 25 degrees C was generally higher than the ones at 15 degrees C and 20 degrees C. Steinernema feltiae DDKB-17 isolate caused the highest mortality (86%) against S. granarius adults at all temperatures tested. The virulence of the tested isolates on R. dominica adults did not exceed 44% at all temperatures and concentrations tested. UMK-7 and AVB-15 isolates were the most virulent isolates against E. kuehniella larvae with a mortality rate of 100%. Based on the results obtained from the laboratory tests, it appeared that the isolates tested have a good potential for the management of S. granarius, R. dominica and E. kuehniella.
