Potential of Local Entomopathogenic Nematode Isolates to Control the Adults of the Scarab Beetle, Epicometis hirta (Coleoptera: Scarabaeidae)*

Abstract

The scarab beetle, Epicometis (Tropinota) hirta (Poda) (Coleoptera: Scarabaeidae), is a serious pest that feeds and destroys developing and blossoming flowers of apple plants. The pest has recently been reported more frequently from apple orchards in Turkey. The control of the adults of E. hirta is challenging due to the restrictions on the application of the chemicals used against the adults during the flowering period of apple orchards in Turkey. Other control methods fail to achieve desired results in the control of the adults. Therefore, there is an increasing need for more sustainable and environmentally-friendly control methods against the adults of E. hirta. In the present study, the pathogenicity of Turkish entomopathogenic nematode (EPN) isolates was evaluated using adults of this pest under laboratory conditions, toward developing an EPN-based integrated E. hirta control plan. Virulence of local EPN isolates against E. hirta was tested in 12-well bioassay plates containing sterile soil treated with different EPN concentrations (0, 190 and 380 IJs adult-1) and then incubated at 25 or 30 oC. All the EPNs isolates caused high mortality ranging from 45 to 100% at 25 oC, or 60 to 100% at 30oC, respectively. The local Steinernema carpocapsae (Weiser) (Nematoda: Rhabditida) isolate E76-S from Turkey was the most efficient, achieving the maximum mortality rate (100%) at both temperatures. The evidence of this study gave promising results for the control of the adults of E. hirta using local EPN isolates but further studies should be carried out in field conditions to determine the field performance of EPNs.
