The three native entomopathogenic nematode (EPN) species; Steinernema feltiae, S. carpocapsae and Heterorhabditis bacteriophora, isolated from Turkey, were tested for the control of the lesser grain borer, Rhyzopertha dominica (F.) (Coleoptera: Bostrichidae) under laboratory conditions. The study was conducted at the Department of Entomology, Plant Protection Central Research Institute, Ankara, Turkey in 2013. Suspensions of the nematodes were applied at three different concentrations (500, 1000 and 2000IJs insect-1 or approximately 78, 157 and 314IJcm-2) and incubated at three different temperatures (15, 20 and 25°C). Mortality rate of the beetle's adults was assessed one week post application. Mortality rates were significantly higher at all the nematode treatments than in the control at 20 and 25°C. S. carpocapsae species showed highest mortality rates (37.95 and 54.06%) at the higher doses of (1000 and 2000IJs insect-1), respectively at 25°C. [ABSTRACT FROM AUTHOR]
