چکیده

Abstract Background Potato tuber worm (PTM) [ Phthorimaea operculella (Zeller) (Lepidoptera: Gelechiidae)] is one of the most significant and widespread pests potato. PTM damages potatoes both in field potato storage areas. Control pest getting harder as it developing resistance to pesticides. Several entomopathogenic nematode (EPN) species have been reported successfully control numerous agricultural worldwide. The main aim study was isolate native nematode/s a biological agent against P. . Morphometric measurements infective juvenile (IJ) sequencing characterization internal transcribed spacer (ITS) region used identify level. efficacy EPN Z-1 obtained from Zonguldak province, Turkey tested different life stages pest. Experiments were conducted 150 ml plastic pots containing sterile soil mixture. Four concentrations (i.e., 0, 250, 500 1000 IJs/ml) applied soil. Data relating mortality collected daily till 6 days after inoculation. Results Molecular analyses based on ITS sequence morphometric data revealed that Heterorhabditis bacteriophora Mortality rates larvae exposed 500, IJs/ml 62.9 ± 9.8, 74.0 3.7, 92.5 3.7%, respectively. There non-significant differences among for pupal highest concentration caused 25.6% mortality. Conclusions results H. effective late-stage under laboratory conditions. Therefore, can be an alternative management option
