Abstract
The purpose of the following work was to explore the potential use of these nematodes and fungi as control agents of adult Japanese beetles. Twenty strains of Steinernema and Heterorhabditis nematodes were evaluated for their ability to cause mortality to the adult beetles. All strains caused significant mortality, compared to the control treatment. The ability of four nematode strains to infect and reproduce in adult beetles was also examined. While both genera were able to infect and kill the beetles, only Steinernema strains able to produce offspring. Steinernema scarabaei and Beauveria bassiana were placed in outdoor pheromone traps, in order to test them in the field. Beetles caught in the trap were observed for subsequent mortality and evidence of infection. S. scarabaei was unable to cause infection in the trap, and B. bassiana provided greater than 80% control, with over 70% of cadavers in that treatment developing mycelial growth.
