Abstract

The Sesaot Nature Tourism Forest Area is a tourist area and an area that is used for the production of several plantation commodities, along with increasing human activities in the Sesaot Nature Tourism Forest area, it raises questions related to the state of its ecosystem, one aspect that reflects the state of the ecosystem, namely the diversity of soil fauna. The sample locations are divided into three paths based on the characteristics of the ecosystem, namely the waterway which is niche points located along the river flow, the middle lane in the form of a path around a forest area filled with large tree stands, and the edge lane which is a path located in the middle of the river around residential areas and rice fields. The purpose of this study was to determine the index of diversity, evenness of species, and species richness of soil fauna in the Sesaot Nature Tourism Forest. Sampling of soil fauna using the pitt fall trap method is placed along 3 predetermined paths. The results showed that in the Sesaot Nature Tourism Forest, there were at least 30 types of soil fauna dominated by the Formicidae family. The highest soil fauna diversity index was found in the waterway with 2.24, followed by the edge lane at 2.22, and the middle lane at 1.13. The evenness value of soil surface fauna species in the Sesaot Nature Tourism Forest in the waterway is 0.66, followed by 0.65 in the edge lane, and 0.33 in the waterway. The highest value of species richness (Margalef index) was found in the waterway with 3.26, followed by the edge and middle lane with 2.69.

Abstract

The objective of this study was to assess the ratio of fruit fly captures using attractants derived from basil and celery extracts, as well as to examine the impact of attractant concentrations in basil and celery leaf extracts on fruit fly catches. Traps made from recycled mineral water bottles were baited with basil and celery extracts containing essential oils known for their attractiveness to fruit flies. The findings indicated that traps using basil extract captured a greater number of fruit flies compared to those with celery extract. Furthermore, varying concentrations of the attractants significantly influenced fruit fly captures. The highest yield of fruit fly captures was observed at a 20% concentration of basil extract. The 20% concentration of basil extract had a higher number of fruit fly captures compared to the 10% and 30% basil extract concentrations, as well as the 10%, 20%, and 30% celery extract concentrations. The study results demonstrated a significant difference in the number of fruit fly captures between basil and celery extracts, with the highest number of captures observed with a 20% concentration of basil extract.

Abstract

Several Odonata studies on Lombok Island still focus on forest and river habitat types. This causes the diversity of this insect group to be unknown in other habitats such as rice fields. This research aims to explore the richness of dragonfly species in the rice field ecosystem of Perian village, Montong Gading subdistrict, East Lombok district. Sample collection was carried out in May – June 2022. Dragonfly searches were carried out in the morning from 08.00 – 12.00, and in the afternoon from 14.00 – 18.00 on two transects determined purposively. The odonata found were documented using a digital camera, and captured using insect nets. Samples that were successfully collected were identified to the species taxon. The total odonata we found were 2 suborders, 5 families and 11 species. The suborder Zygoptera is the group with the highest species richness. For families, Libellulidae and Coenagrionida are the families with the highest species richness compared to other families. Of the 11 species that we found, 1 species is endemic, namely Euphaea lara lombokensis. Compared with the results of previous research conducted in Suranadi and Batu Bolong River, there are 5 species which are new records. The five species are Copera ciliata, Rhinocypha bisignata, Ischnura senegalensis, Ischnura heterosticta, and Brachythemis contaminata. The results of this study indicate that there are more species from the Odonata order on Lombok Island compared to previous reports.
