- Abstract
Potential of three native Turkish isolates of entomopathogenic nematodes (EPNs) (Steinernema feltiae, S. carpocapsae and Heterorhabditis bacteriophora) was evaluated against Holotrichapion pullum (Gyllenhal) (Coleoptera, Apionidae) under laboratory conditions. Suspensions of EPNs were applied at three concentrations (500, 1000 and 2000 IJs ml-1) and at two temperatures (15 and 20°C). After one week, mortality rate of H. pullum adults was assessed. Mortality rate was higher in the nematode treatments than in the control. All nematodes showed more effect depending on temperature increase. At 20°C and all concentrations, S. carpocapsae was the most effect by (80.43, 83.35 and 82.15% mortality, respectively). S. feltiae had relatively high effects (30.44, 41.93 and 35.21% mortality, respectively), while H. bacteriophora had the lowest rates (24.15, 27.16 and 30.55% mortality, respectively). At 15°C, EPNs showed an effect less than 25%. Obtained results indicated that H. pullum adults are susceptible to EPNs infection in particular for S. carpocapsae (the black sea strain). Further studies are required under laboratory and field conditions.
