Efficacy of entomopathogenic nematode isolates from Turkey against wheat stink bug, Aelia rostrata Boheman (Hemiptera: Pentatomidae) adults under laboratory conditions

Abstract Background The wheat stink bug, Aelia rostrata Boheman (Hemiptera: Pentatomidae), is one of the harmful insects that caused significant product losses in cereals due to outbreaks. Entomopathogenic nematodes (EPNs) are natural enemies soil insect pests whose effects as a biocontrol agent against many have been demonstrated by laboratories and field/garden studies world. present laboratory studies, using native EPNs [ Steinernema carpocapsae (Black sea isolate), S. feltiae (isolate 09-31) (Aydin isolate) Heterorhabditis bacteriophora 09-43) isolate)] bug adults, were carried out. Results In application plastic cups, highest mortality rates (75 70%) on occurred at 200 IJs cm −2 concentration isolate 15 12 °C, respectively. other tested nematode species, was observed H. isolates, with 65–35% 55–25%, most pathogenic among three tested. Conclusions It concluded had potential A. . applications great for management pest. Effective use should be evaluated integrated pest strategies between biological control agents. According experiments results, field trials conducted future studies.
