Abstract
Insects are one of the biotic components that make up the mangrove ecosystem. The diversity of insects is believed to be used as one of the bio-indicators of the condition of the mangrove ecosystem. This study aimed at determining the profile of insect diversity in the mangrove ecosystem in Menipo Nature Tourism Park, East Amarasi, East Nusa Tenggara. The study was conducted in February 2018 to June 2018. Insect capture was carried out using the yellow pan trap method. Data analysis was done quantitatively to determine the profile of mangrove insects. The profile of mangrove insect diversity was determined based on species richness index, Shannon-Wienner diversity index, evenness index, and Jaccard similarity index. The results showed that there were 14 species, 11 families, and 5 orders with a total number of 56 individuals in mangrove ecosystem of Menipo Nature Tourism Park. Genetic wealth of mangrove buffer was still relatively low (R1 <3.5). The diversity of mangrove insects was classified as moderate (H’ = 1 - 3). All mangrove insects had almost the same level of evenness (E <1). The similarity index of mangrove insects in Menipo Nature Tourism Park, East Amarasi ranges from 0.18 to 0.5, meaning that the similarity of mangrove insect species among the three stations was different from each other.
