Abstract:
The study was conducted at eight streams in various parts of Terengganu and an estuary in
Tumpat, Kelantan between 22 May 2006 until 13 October 2006. They were Sungai
Jeneris, Sungai Nerus, Lata Tembakah, Lata Belatan, Sungai Kemat, Belukar Bukit and
two unnamed streams of Bukit Bauk. A total of 1431 aquatic insects' individuals were
collected, consisting of seven orders and 43 families. Perlidae from the order Plecoptera
had the highest collected individuals (34%) followed with Hydropscychidae (22%) (order
Trichoptera) and Heptageniidae (16%) (order Ephemeroptera). Lata Tembakah recorded
the most individuals collected with 423 while Tumpat was the least with 46 individuals
only. Rocky streams beds, fast flowing water with little debris and forest litter maximized
the collection of aquatic insects in some streams.
