Abstract

This study describes the basic ecological characteristics of the entomopathogenic nematode Steinernema monticolum that was originally isolated from soil in a mountain forest on Mount Jiri, Republic of Korea. Under laboratoryconditions, S. monticolum infected a wide range of insect species but appeared best adapted to lepidopteran larvae as hosts. It uses an intermediate foraging strategy with a low attachment rate to mobile hosts on the soil surface and poor infection of sedentary hosts placed at greater than or equalto5 cm soil depth. S. monticolum infected hosts over a wide range of soil moisture ranging from -1500 kPa to -3 kPa. It has a wide thermal activity range with optimum infectivity from 12 to 25 degreesC. When stored in water over a 6 month period, S. monticolum persisted well from 5 to 25 degreesC. Its infectivity also remained high when stored from 5 to 15 degreesC but declined faster at 25 degreesC. Because of its foraging strategy and adaptation to cool temperatures, S. monticolum has potential for the control of pests, especially Lepidoptera, that hibernate in the upper soil layer or soil litter.
