| description | A preliminary study on three aquatic insect orders, Ephemeroptera (mayfly), Plecoptera (stonefly) and Trichoptera (caddisJly) (EPT) was carried out in Kerian River Basin (KRB), at the border of Kedah-Perak states, in
Peninsular Malaysia. Ephemeroptera comprising six families of 10 genera and 460 individuals was the most
dominant order. Although both Plecoptera and Trichoptera was represented l7y similar number of families,
stoneflies were found to be more abundant in the river basin. In order of abundance, stonefly Tetropina, mayJlies
Caenis, and centroptilum, and caddisJly Macrostemum were the most common geneva. The diversity of the
EPTfauna ranged 1.41 - 2.65 with significantly different distribution (ANOVA, F/534o = 1.68) at P= 0.05 and
fairly unevenly distributed (Evennes Index Ranged 0.15-0.95). The EPT Richness i~dices were in low ranges in
all river and the FBI scores categorised the water quality of river in this river basin as moderately polluted to
excellent. |
