| Abstract | The decreasing of firefly population is due to the alteration of habitats such as pollution, physical changes, and human activities that are voraciously destroying the environment. This study aims to determine the abundance of the firefly population, to measure the river water quality level and to analyse the relationship between the firefly population and the river water quality. Six sampling stations were set up along Cherating River. The photo visual method was used for the firefly sampling and was conducted on three different nights. The water sampling was conducted at two different times of day and night. A total of 243 individual fireflies were counted from each sampling station, with Pteroptyx bearni was the dominant species in the area. Based on Water Quality Index (WQI) and Interim National Water Quality Standards (INWQS), the water quality of Cherating River was in Class III (medium contaminated). The Pearson correlation result showed that there was a strong positive correlation between dissolvedoxygen (DO) and the firefly population, but strongly negatively correlated with temperature, biochemical oxygen demand (BOD), chemical oxygen demand (COD), and ammonia nitrogen.The parameters of pH, total suspended solid (TSS) and Escherichia coli did not show any correlation with firefly populations. Therefore, only temperature, DO, BOD, COD and ammonia nitrogen seem to influence the population abundance of fireflies in Cherating River. To agitate the abundance of firefly populations, organic pollutants should be removed from the water body to prevent DO from decreasing while increasing BOD, COD, and Ammonia-nitrogen. |
