In this book chapter all activities that were performed at the Chair of Phytomedicine in the field of entomopathogenic nematodes (EN) are presented. In the beginning, the first laboratory trials from the time, when EN were still the exotic organisms, methods of soil sampling and detection of five EN species for indigenous in Slovenia, are described. Furthermore, the trials in greenhouses as well as in the open field, where satisfying efficacy of biological control agents mentioned against different insect pests are presented. On the basis of the results of the researches described in this chapter, EN are now already widely used among Slovenian producers of food.

In our investigation the flight of common cockchafer was monitored using light traps in 2007, the year before using the mycoinsecticide Melocont-Pilzgerste®, and in 2010, the year after its 3-year application (2007-2009). In these two years, in Zadlog, from 20 April till 10 June traps were checked daily and captured beetles were counted. In 2010 altogether catch reached just 42 % of the catch in 2007. The start of swarming mainly depends on the temperature and later the intensity of flight can be also affected by the rainfall. The flight curve shows three peaks in both years; among which one is very distinctive. In the period of absolute culmination of swarming the number of males prevailed over the females and only at the end of flight period there were more female beetles caught in the light traps. After the 3-year application of the mycoinsecticide Melocont-Pilzgerste® the adult population of Melolontha melolontha beetles was strongly reduced.
