Community compositions and population dynamics of true bugs (Hemipera: Heteroptera) in the Taimali Experimental Forest

Nocturnal bugs were collected using the light traps at the first and second work posts in the Taimali Experimental Forest from January to December in 2005. A total of 848 individuals, belonging to 58 species in 12 families, were collected during the sampling period. Lyaeidae is the most diverse family with 16 species recorded in the study area. Largidae is the most dominant family, accounting 52.8% of total abundance. The second work post showed more species and higher abundance of true bugs than the first work post, but the Shannon-Wiener diversity index was lower due to the dominance of Physopelta cincticollis. Eighty species belonging to 17 families of bugs were collected in the daytime. A total of 115 species in 17 families of bugs were collected in the Taimali Experimental Forest. Lists of Heteroptera in the Taimali Experimental Forest were provided, and the population dynamics of dominant species and the relationships between bugs and plants were also discussed.
