Diversity and distribution of immature trichoptera and odonata in Taman Negara Kuala Koh in Kelantan

The aquatic insect community is one of the most important faunas in the rivers that are established for biological indicators. This study focuses on to determine the diversity and distribution of Trichoptera and Odonata at three rivers which is Lubuk Sinar, Lubuk Kaloi Bawah and Lubuk Pertang in Taman Negara Kuala Koh, Gua Musang, Kelantan. Trichoptera (caddisflies) and Odonata (damselflies and dragonflies) is an aquatic insect that is very vulnerable to pollution and can only thrive in aquatic environments with good water quality. The distribution of aquatic insect larvae was high at Lubuk Sinar and Lubuk Kaloi Bawah stream of diverse microhabitats. The physicochemical parameters were determined such as pH, temperature, velocity, and dissolved oxygen. The most abundant family in Trichoptera was Leptoceridae with 9 total individuals and 3 genera, Ceraclea, Setodes, and Apataniidae. As a result, the project’s purpose is to collect baseline data for future study and conservation initiatives.
