- Abstract
Dung beetles serve as the intermediate host for Streptopharagus pigmentatus, a nematode parasite that infects an old world primate, the Japanese Macaque ( Macaca fuscata). This study compares the behaviors of infected and uninfected beetles in both transmission dynamics and the ecological role of the parasite. The results suggest that parasitism does not alter the beetle's use of shelter or choice of substrate on Yakushima Island, Japan. However, infected beetles consume significantly less feces. Dung beetles remove the majority of fecal material in this forest ecosystem, eliminating breeding grounds for many insect pests and burying nutrients that are essential for plant health. Thus, the nematode parasite S. pigmentatus, by altering its host's behavior, changes the availability of fecal resources to both plant and animal communities and should therefore be classified as an ecosystem engineer.
