Insect composition diversity in Can Gio mangrove forest, Ho Chi Minh city

Abstract

The restored mangrove ecosystem creates favorable conditions for animals and plants to return to life and develop, including insects. Conducting surveys on insect species composition on 12 routes of different habitats in Can Gio Mangrove Forest from 2017 to 2022. Record information and collect specimens of all insects. Assess the insect flora through 2 diversity indicators: Shannon Wiener (H’) and Simpson dominance (D). The results of the study recorded 374 species, of which 10 orders and 49 families were identified. Lepidoptera and Hymenoptera have the largest number of species, accounting for 30.5% and 24.9%, respectively, and are found frequently in all habitats. Recorded 9 species of mangrove tree pests, 1 species of Attacus atlas (Atlas moth) is a large and rare species. The flora in the Can Gio Mangrove Forest has high diversity (mean H’ 3.42 ± 0.23) and species dominance (mean D 0.043 ± 0.010). The research results are the initial database for the conservation of biodiversity in the Can Gio mangrove ecosystem.
