Abstract

Butterflies are an important example of pollinating insects of the Order Lepidoptera. The presence of butterfly pollinating insects in nature is highly dependent or influenced by the availability of flowering plants visited in the ecosystem. The purpose of this study was to determine the diversity and abundance of butterfly pollinator in flowering plants. A direct survey method (visual) with a radius of ± 100-250 m² was done with scan sampling technique. Parameters measured were the abundance and the species richness of butterflies visited flowering plants as well as the species richness of flowering plants visited by butterflies pollinator. The data obtained were analyzed using the the Shannon-Wiener diversity index (H’). The results showed that at study sites in secondary forest habitats and yards, 25 species of butterfly pollinators were found consisting of 5 families with 308 individuals. Nine  species of flowering plants visited by butterfly pollinators. The Jatropha integerrima was the most visited by butterfly pollinators with 11 species, followed by Hibiscus rosa-sinensis and Ixora coccinea (9 species), Clerodendron paniculatum (6 species), Mussaenda ralateensis (4 species), Bidens pilosa and Celosia argentea (3 species), Zinnia elegans visited by 2 species and Portulaca oleracea visited by 1 species of butterfly pollinators. Based on the calculation, the value of Shannon-Wiener index (H') is 2.946, which indicates that the level of diversity of butterfly pollinators in the medium category.

Abstract

Insects have a very important role in maintaining the balance of the forest ecosystem and supporting the continuity of life in the forest. The main roles of insects in the forest include as pollinators, predators, decomposers, pest controllers and as indicators of environmental health. However, there is no data regarding the diversity and ecological function of insects in the Isyo Hills Rhepang Muaif tourist forest. Insect sampling technique uses the scan sampling method. Insect diversity data is analyzed using the Shannon-Wiener species diversity index. Based on research conducted in the Isyo Hills Rhepang Muaif Tourism Forest, Nimbokrang District, Jayapura Regency, a total of 606 individual insects were found with 54 types of insects representing 8 different orders, namely: Order Lepidoptera (26 types= 48%), Orthoptera (7 types= 13%), Coleoptera (6 types= 11%), Hemiptera (6 types= 11%), Odonata (4 types= 7%), Hymenoptera (2 types = 4%), Diptera (2 types = 4%) and the Order Blattodea (1 type= 2%). The results of the analysis show that species diversity in each insect order is in the medium and low categories. The Shannon-Wiener index (H') value for each order ranges from 0–2.99. Insects obtained from sampling results fall into eight levels of important ecological roles (feeding groups/ functional groups/trophic guilds) in nature, namely pollinators, phytophagous, xylophagous, predators, omnivores, carnivores, granivores and detrivores
