Assemblage Patterns of Hymenoptera at Different Elevations of Gunung Datuk, Rembau

A study on abundance and diversity of Hymenoptera was conducted inGunung Datuk, Rembau. Samplings were conducted from November 2014 toFebruary 2015 using six Malaise traps. Three traps were placed at Site 1 at700m height for high elevation and the remaining traps were placed at Site 2at 200m height for low elevation. A total number of 221 Hymenopteran werecollected which consist of nine families namely Ichneumonidae, Formicidae,Braconidae, Bethylidae, Evaniidae, Tiphiidae, Vespidae, Pompilidae andApidae. In this study, 93 individuals were obtained from Site 1, comprisingnine families and 43 morphospecies while 127 individuals were obtainedfrom Site 2 with nine families and 45 morphospecies. Formicidae was themost dominant family collected from both sites with a total of 104 individualswhile the least family recorded was Apidae with only one individual.Shannon’s Weiner Diversity Index (H’) showed Site 1 had the higher diversityvalue with H’ = 3.17 compared to Site 2 with value H’ = 3.12. For EvennessIndex, Site 1 had higher value compared to Site 2 with E’ = 0.84 and E’ =0.82 respectively. Moreover, for Margalef Richness Index, Site 1 recordedR’ = 9.24 while site two recorded R’ = 9.08 which concluded that Site 1had higher species richness compared to Site 2. Paired t-test showed thatboth sites had no significant difference with p 0.05. Overall study showedthat the diversity and abundance of Hymenoptera in Gunung Datuk werelow since the value of H’ is less than 3.50.
