The mangrove area in Donggala Regency is a unique and potential area, but the area tends to be threatened by increasing mining activities in the area. Management of the mangrove area in Donggala Regency as an ecotourism area is an alternative form as an innovative effort to maintain environmental functions as a provider of environmental services in order to remain sustainable. This study was aimed at analyzing the Local Community Ecological Knowledge (LCEK) pertaining to mangrove ecosystems and ecotourism development in Donggala Regency. The study used a survey method, utilizing the analysis of the tourism suitability index (IKW) and the carrying capacity of the area (DDK). Community knowledge and perceptions were based on a Likert scale scoring system. The results of the study and the discussion showed that people in Donggala Regency had local ecological knowledge of mangrove forests, especially mangrove habitats, mangrove damage factors and the impact of mangrove damage was better than the function of mangroves. Utilization of mangrove ecosystems in Donggala Regency is very diverse, ranging from the utilization of mangrove stems, fruits, leaves and roots and fishery products such as small fish and shellfish. The community's understanding of ecotourism activities was very good and they agreed with the ecotourism activities that were carried out.

Insect pollinators and plants have a mutually beneficial interaction. Insects get their needs in the form of pollen and nectar, while plants benefit from the pollination process. Dragon fruit (Hylocereus polyrhizus) is one of the fruit plants that is now starting to be widely cultivated in Indonesia after its first entry in the early 2000s. This study aims to analyze the diversity of visitor and pollinating insects and their role in fruit formation in dragon fruit plants. The research was conducted starting in October 2023. Sampling and observation of the diversity of visitor insects and pollinators were carried out in one of the gardens in Parigi Moutong Regency. Identification of visitor insects, and data analysis were carried out at the Biology Laboratory, Faculty of Teacher Training and Education, Tadulako University. Flower visitor insects found in this study were 7 species, namely Tetragonula clypearis, T. laeviceps, Scolia sp., butterflies E. Phaenareta and M. leda, D. thoracicus, and Stenogastrine sp. Five insect species have a role as pollinators on dragon fruit plants. Two insect species are predatory insects. Insect visitation activity on dragon fruit flowers was highest in the morning to afternoon and decreased in the afternoon.

Soil arthropods play an important role in nutrient cycling and maintenance of soil structure. Thus, their abundance and diver­sity can indicate the biological quality of the soil. Due to different soil management practices, arthropods are also very sensitive to en­vironmental changes. This study aims to analyze the abundance and diversity of soil arthropods and the environmental factors that sup­port the abundance of soil arthropods in terrestrial of Situ Lengkong Panjalu, West Java, Indonesia. The methods used to obtain samples of soil arthropods are pitfall trap. Soil arthropod data were analyzed to determine the Shannon diversity index (H'), Margalef richness index (R), and Evenness index (E). The effect of abiotic environmental fac­tors was analyzed using Principal Component Analysis (PCA). A total of 1263 arthropods were found in Situ Lengkong Panjalu, belonging to 11 orders, 24 families, and 32 morphospecies. The current work determined the scores of H'= 2.08, R = 3,08, and E = 0.72 of soil arthropods in Situ Lengkong Panjalu, West Java, Indonesia. Results revealed that humidity is one such environmental parameter affecting the presence of soil arthropods in Situ Lengkong Panjalu, West Java, Indonesia. This research can be used as a guide in validating and conservation of the habitat of soil arthropod species on West Java

A catalog provides an index to previous studies in taxonomy, behavioral research, and pollination ecology, thus consolidating the existing knowledge in an accessible format. In this study, we explore the annotated catalog and bibliography of the Indonesian meliponini stingless bees (Hymenoptera, Apidae, Apinae, Meliponini). The catalog format is arranged based on Rasmussen (2008). All available literature was reviewed for compiling this catalog and bibliography. References to a Meliponini genus only were not included in the list of references. Cited references must have used a trackable specific epithet to have been included. In total, Indonesia has 52 recorded stingless bee species across the Indonesian archipelagoes of Sumatera (27 species), Java (13 species), Nusa Tenggara (1 species), Kalimantan (34 species), Sulawesi (8 species), Bali (1 species), Maluku (4 species), and Papua (12 species). After the data was updated, there was an increase in the number of stingless bee species in Indonesia, namely 46 species (before update) to 52 species (after update). An up-to-date, comprehensive taxonomic and biological catalog is fundamental to any comparative evolutionary, ecological, and behavioral research on any group of organisms.

Background: Habitat is a place for living things to grow and develop. Differences in habitat in an area can affect the size of an organism. This study aims to determine the morphometric variations of Tetragonula laeviceps found in urban and forest habitats in Central Sulawesi Province. Methods: This research was conducted with roaming technique. Morphometric characters observed were 35 characters of stingless bee and analyzed using Microsoft Excel software. Results: The results of this study indicated that the morphometric size variation of T. laeviceps found in forest habitats (3.58 mm) is greater than that of wild bee in urban habitats (3.05 mm). Conclusions: Different habitat characteristics can affect the morphometry variations of the bee, especially in T. laeviceps species. The bee's morphometry body size is greater than in the forest habitat, because in that habitat there are environmental temperatures and types of plant sources of nectar which are more supportive for bee life compared to urban habitats.

The diversity of pollinating insects is used as conservation management. Pollen is gametophyte from male which can give characteristics to its offspring. The pollen carried by bees can be used as an identification of feed favored by bees. This study aims to identity pollen derived from the legs of stingless bees based on the color morphological characteristics of the pollen. The methods include color identification of pollen collected by stingless bees, pollen extraction, acetolysis, and pollen identification. Pollen with the same species at the study site has a color that is not much different. Stingless bees take pollen based on the size and distance of the plant to the hive. Smell and color as a secondary binder for stingless bees. Different plant pollen species can also be influenced by the protein requirements of each stingless bee colony. It can recognize the presence of flowering plants aroud the hive. The size of pollen can affect the bees in taking plant pollen.

Knowledge of behavior is very important to maintain the habitat of the maleo as an endemic animal to Sulawesi that must be preserved. Research takes place in March-December 2021. The research location is in the Saluki Lore Lindu National Park, Central Sulawesi Province. The study took place in March-December 2021. The findings targeted in the study are: (1) Information on egg-laying behavior, (2). When laying eggs, (3) After laying eggs, (4) Determining the length of time for laying eggs, (5) Physical characteristics of the nest and vegetation. The research method used the survey method. Observations of maleo bird activity were carried out every day for 3 months in the egg-laying season from May to July. The results showed that the physical condition of the average nest depth was 67.78 cm, the average nest width was 52.78 cm, the average nest temperature was 33.44°C, the nest humidity was 76.11% and, the soil acidity (pH) with an average of 6.35. The vegetation found at the nesting site consisted of 18 species. The maleo maleo bird's egg-laying behavior activities are playing, snooping (observation), and making a trick hole. There were four activities of female maleo bird laying behavior, namely playing, digging holes for laying eggs, lurking, making trick holes and laying eggs. The duration of time needed by male maleo birds when playing, snooping, making holes, until the female finishes laying eggs, which takes 92 minutes. While the female takes 84 minutes.

This study aims to determine the diversity of insects found in tomato plants (Lycoperscium escelentum Mill.). This research was conducted on tomato farming land in the village of Ogomolos, Mepanga District, Central Sulawesi from February to March 2018. This type of research in descriptive qualitative with a sampling technique using survey methods. This study use three insect trapping techniques (Sweep net, Pitfall trap and Yellos sticky trap). Based on the result of the research that has been carried out, the results obtained are 658 individuals consisting of 18 types of nsects from 9 orders and 16 families. The value of the insect diversity index of Shannor-Weiner (H’) = 2,282 is classified as moderate.

Hymenopteran order is an order of insects that is useful for pollinating plants, producing honey and wax and can kill insects that harm plants (pests). This study aims to determine the results of collections of Hymenoptera parasitoid insects from forest stands and rice fields. The research was carried out in January-March 2019. The sampling locations were carried out in two types of areas, namely forest stands and rice fields. Based on the results of the study, it was found that the two orders of insects that had a dominant number from the collection were the Order Diptera and Order Hymenoptera. The number of Hymenoptera insects in the forest stands and rice fields were 1.586 individuals and 2.179 individuals, respectively, with a total of 21 families of parasitoid insects. The use of separators in the collection of Hymenoptera parasitoid insects has several advantages compared to using other insect net, namely making it easier to collect insects and the number of insects caught is also higher.
