| Abstract/Contents: | "Larvae of Scarabaeidae have emerged as the most important insect pests of turfgrass on golf courses in Japan. These larvae are generally very difficult to control with chemicals. Recently, the efficacy of an entomopathogenic nematode, Steinernema kushidai, which is specific to various scarabaeid larvae, was evaluated under laboratory tests and field trials. An evaluation of the infectivity of S. kushidai to five species of scarabaeid larvae was conducted by a plastic cup method (6 cm diameter, 4 cm height) containing 20 g of the leaf mold compost with ca. 1000 infective juveniles per larva. At ten days after inoculation larval mortality in all five species was 100%, which was significantly different from the untreated larvae. From the field trials in 1998, the mortality of Anomala orientalis (oriental beetle) larvae infested with S. kushidai infective juveniles was 85%, compared with 31.7% for diazinon application (0.8 g a.i. m-2). S. kushidai infected mature larvae at soil temperatures ranging from 20°C to 25°C. Furthermore, the infective juveniles of S. kushidai displayed an inability to survive for long times, in some cases more than ten months in areas of high larval density on golf courses. S. kushidai promises to be an effective biological control agent against scarabaeid larvae." |
