Abstract
Nocturnal bugs were collected using light traps at 3 sampling sites in the Lienhuachih area, Nantou County from January to December in 2006. In total, 1833 individuals, belonging to 84 species in 11 families, were collected during the sampling period. Among them, Miridae is the most diverse and dominant family, and Tinginotum perlatum Linnavuor was the most dominant species. More species, a higher abundance, a higher Margalef index, and a higher Shannon-Wiener diversity index were observed at site 1. In addition, 64 species belonging to 14 families of true bugs were collected in the daytime. In total, 126 species in 18 families of bugs were collected in the Lienhuachih area. These data were compared to those from the Taimali Experimental Forest, Taitung County, and relationships between plant diversity and bug diversity were discussed. The results confirmed that bug diversity was positively correlated with vegetation structure and plant diversity.
