| Summary: | Hymenopteran parasitoid is one of the major insect component in the terrestrial ecosystems. A study was
conducted to determine the diversity and abundance of hymenopteran parasitoids in a coastal and inland forest
of Perhentian Island, Terengganu. Three Malaise traps were installed for each sampling points of the plot areas
(i.e. coastal and inland forest). The insect samples were collected after seven days and brought to the laboratory
for sorting, enumerating and identifying from order up to family level. The abundance of parasitoids collected
was analyzed using T-test analysis and Kruskal-Wallis test whilst their diversity was analyzed using the ShannonWeiner Diversity Index (H’). A total of 25 hymenopteran parasitoids comprising of 10 families were identified.
The most abundance families recorded was Braconidae with eight individuals followed by Ceraphronidae with
six individuals whilst Figitidae, Scelionidae and Trichogrammatidae represented by two individuals, respectively.
The diversity of Hymenopteran parasitoids in the coastal forest showed higher diversity value with H’=2.03
than in the inland forest (H’=1.17). The abundance of Hymenopteran parasitoids individuals, however, was not
significantly different (p > 0.05) between coastal forest and the inland forest plots. Overall, this study showed
that the diversity of Hymenopteran parasitoids was higher in the coastal forest although the abundance was not
obviously differed from the inland forest of Perhentian Island. For the future, vegetation species, distribution
and abiotic factors can be taken into consideration in determining the diversity and abundance of Hymenopteran
parasitoids in an island forest. |
