SPECIES DIVERSITY OF DRAGONFLY (ARTHROPODA: ODONATA) AND ITS RELATIONSHIP WITH AIR PARAMETERS AT SG. MUAR, KUALA PILAH

Abstract

The study of diversity and distribution of dragonfly, and their relationship with air parameters including temperature (°C) and humidity (%) at Sungai Muar, Kuala Pilah, Negeri Sembilan was carried out on 14 and 15 March 2020. The sampling of dragonfly was done in two parts of Sungai Muar, Kuala Pilah. For each site, the sampling was conducted in the morning and evening with the air temperature and humidity were recorded at the same time using hygrometer and digital thermometer clock humidity temperature HTC-1. Method that has been used for this study are net sweeping. The samples were collected, preserved and identified until species level. A total of 231 individuals were recorded with Ischnura elegans from Coenagrionidae family as a dominant species with 145 individuals, while the lowest abundance is Pseudagrionidae sp. of Coenagrionidae family with one individual only. For the relationship, there is no significant linear correlation between air parameters with individual number of dragonflies. As a recommendation, the other parameters including air and water parameters should be measured to increase our understanding on the abiotic parameters effects towards the survivability of dragonfly. This research give benefit to society and ecology where it provides knowledge and understanding about dragonfly species and the function of dragonfly as indication of environmental quality. Besides, this research can be used as guidelines for future research and update the checklist of dragonfly in Sungai Muar, Kuala Pilah.
