Abstract: The effects of roadway traffic pollutions and atmospheric pollutants on insects were reviewed based on the recently domestic and international studies. An introduction was presented about the status of roadway traffic pollutions and the impacts of the pollutants of automobile exhausted gas, e.g., sulfur dioxide (SO₂), nitrogen oxide (NO_x, including NO and NO₂), carbon oxide (CO_x, including CO and CO₂), volatile organic compounds (VOCs), acid rain, ozone (O₃) and particulate matters (PM), on the occurrence, performance and population fitness of insects, and the function mechanisms of the above pollutants were also elucidated. Moreover, some topics about the impacts of roadway traffic pollutions on insects were also provided to advise the future research in China. Furthermore, some ecological effects on peripheral environment of road-region ecosystems were also caused by roadway traffic pollutions. In the future, the constructions of ecological roadways should be reinforced in order to alleviate the adverse impacts of traffic pollutions on road region ecosystems.

Key words: Traffic pollution, road-region ecosystem, insect, function mechanism, ecological effect
