The existence of allegations about the presence of various mycorrhizae in the forest area of Fatusene Village, East Miomaffo District, North Central Timor Regency, is a benchmark for assessing the characterization of mycorrhizae in the area. The purpose of this study was to isolate and identify mycorrhizae in the forest area of Fatusene Village, East Miomaffo District, North Central Timor Regency. Mycorrhizal identification begins with sampling the soil under the tree stands using the quadratic method. Soil samples were taken randomly at three points per observation plot with a depth of 0-30 cm from the base of the tree trunk. Separation of spores from soil samples was carried out using a wet sieve technique. Data analysis was carried out descriptively by identifying morphological characters including the shape and color of the spores. The results of mycorrhizal research found in the research location of the forest area of Fatusene Village are endomycorrhizal types, especially arbuscular vesicles. Characterization of mycorrhizal spores showed that there were three different spore genera in soil samples, namely the genus Glomus, Gigaspora and Acaulospora. The three genus found in the soil samples at the study location were present in each dominant tree with different numbers of individuals. The spores of the three mycorrhizal genus found at the study site were 65 spores, with the distribution of 35 spores genus Glomus, 20 spores genus Acaulospora and 10 spores the genus Gigaspora. The characters the genus glomus are round, slightly round, oval and brown and dark brown in, have hyphae and are equipped with oily fluid spots on cook spores. The characters the genus Acaulospora are round and oval in shape, blackish brown in color, brownish red and brownish yellow, have several layers of cell walls, one of which is dark in color. The characters the genus Gigaspora are irregular in shape, somewhat round and round, yellow, brownish yellow, to yellowish brown, large in size and black spore walls. Conclusion The mycorrhizae found in the study site were endomycorrhizal, especially arbuscular vesicles which consisted of 3 genera, namely Glomus, Acaulospora and Gigaspora. The characters of the genus glomus are round to oval in shape, dark brown in color, have hyphae and spotting of oil. The characters the genus Acaulospora are round and oblong, brownish yellow in color, have several layers of cell walls.

Insect diversity is believed to be used as a bio-indicator of spring quality. This study aimed at determining the spring insect diversity around the Mutis Timau Nature Reserve. The study was conducted from June to August 2019. Insects were caught by using the yellow pan trap and hand sorting. The diversity of spring insects was determined based on the Shannon-Wienner diversity index (H'), species richness index (R1), species dominance index (D), and evenness index (E). The results showed that 16 species belong to 11 families, and 5 orders of insects. The families included Gryllidae, Gryllotalpidae, Tetrigidae, Formicidae, Pompilidae, Apidae, Ochteridae, Veliidae, Hydrometridae, Nepidae, Coenagrionidae, Libellulidae, Carabidae, and Coccinellidae. The Shannon-Wiener species diversity index and the wealth index of the species of springs were classified as moderate (H '= 2.12 and R1 = 4.19). There was no type of spring insects dominated (D = 0.23). All springs insects were found to have almost the same level of evenness (E<1), with a value of 0.76. Abiotic factors such as pH and soil temperature were within the tolerance range of spring insects. Key words: Insects diversity, Spring, Mutis Timau Nature Reserve
