Diversity, Species Richness and Evenness of Arctiidae and Geometriidae Moth Fauna of Barpeta and Cachar District

M. Choudhury | P. Choudhury

Abstract: Moth species were studied from some selected districts of Assam (i. e. , Cachar and Barpeta district) to determine their diversity index, species richness and evenness of Arctiidae and Geometriidae family of the moth fauna. The moths were collected by applying specialized trapping methods using UV light operating during night. Collected moth species were identified up to family-genus-species level. The diversity index (Shanon-Wiener diversity index, 1949) species richness (Margalefs index, 1958) and evenness (Pielou, 1996), of moth fauna werethen calculated. Based on the calculation, it was found that the diversity index, species richness and evenness of Arctiide moth fauna in Cachar were 6.955, 0.6557, 3.104 and geometride moth fauna were3.433, 7.902, and 0.8153 respectively. The diversity index, species richness and eveness of Arctiidaemoth fauna were 3.027, 6.981, 0.6065 andGeometriidae moth fauna were 3.207, 7.37, and 0.7247 respectively in Barpeta district.
