Abstract

As social insects, termites live in a colony that consist of reproductive (drone and queen), and non-reproductive (soldiers and workers) castes. Workers obtain their food directly from wood, humus, and other substances that contain cellulose. The objective of this study was to examine the alimentary canal of the Neotermes bosei workers. Observations of gut transverse section were carried out through the length, perimeter, and area of each alimentary canal region. The results showed that total length of N. bosei alimentary canal was 13.71+1.28 mm. The canal was divided into fore-, mid-, and hindgut which were 24, 28, and 48%, respectively of the gut total length. Two types of alimentary canal epithelial cells were found, i.e. the squamous and transitional cells. Areas covered with thick muscular tissues were crop, proventriculus, and rectum. Proventriculus was characterized with six large dentitions. There was no gastric caeca in N. bosei midgut, which commonly occurred in chewing insect. Secretory cells .were observed at proventriculus and ventriculus regions. Cardiac valve was found at the anterior end of ventriculus. Area with the largest outer perimeter was the rectum pouch. Enteric valve had three internal folds.Key words: drywood termites, alimentary canal, histology, Kalotermitidae

Abstract

Macrobrachium pilimanus is a type of freshwater prawn commonly found in Indonesian waters. This species is reported to have abbreviated larval development (ALD), and its life cycle is greatly influenced by the conditions of their environment, including the water currents. This study examined the relationship between water currents and the daily behavior of the M. pilimanus freshwater prawn. We observed the behavioral pattern using the scan sampling method on six individuals from two treatments (strong current and slow current) over 64 hours, with observations taken every 60 minutes. Our results showed a dominant behavior of M. pilimanus hiding in places with strong currents and high ingestion behavior. In contrast, the prawns that were not exposed to water currents predominantly showed partially inactive behavior.

Abstract

Tetragonula laeviceps Smith are widely found and cultivated in Indonesia. They play a crucial role in providing ecological services as pollinators of plants. However, there has been a global concern of bees’ population decline, which may be attributed to the intensive use of insecticides. This study aimed to analyze the toxicity level of several insecticide active ingredients and the effects of insecticide exposure on the physiology of T. laeviceps. Four insecticides active ingredients, carbosulfan, clothianidin, diafenthiuron, and tetraniliprole were tested for toxicity against T. laeviceps through dermal and oral exposures at five concentration levels. Bee preference testing was conducted through olfactory tests using a Y-tube olfactometer. Results showed that insecticide exposure affected the visitation length of T. laeviceps (P = 0.006), but not its visitation frequency (P = 0.286). Carbosulfan and clothianidin were toxic to T. laeviceps, both dermally (LC50 31.28 and 0.09 ppm, respectively) and orally (LC50 28.51 and 0.41 ppm, respectively). Meanwhile, diafentiuron and tetraniliprole were more harmful to bees during dermal exposure (LC50 7,882 and 148.81 ppm, respectively) compared to oral exposure (LC50 53,983 and 5,240 ppm, respectively). The toxicity levels of the insecticides carbosulfan and clothianidin are classified as highly toxic and harmful, while diafentiuron and tetraniliprole are not harmful to T. laeviceps bees. In addition, the capability of bees to consume feed was also significantly decreased due to exposure to carbosulfan (10,000 and 3,000 ppm) and clothianidin (300; 30; 3; 0,3; and 0,03 ppm) insecticides. Information of the toxicity levels and effects of various insecticides on bees may contribute to the development of insecticide management to keep the survival of bees in agricultural areas.

Abstract

Plantation landscapes offer ecological resources for commercial beekeeping, yet the sustainability of Acacia crassicarpa honey production in Sumatra faces institutional and market constraints. This study assesses the development potential of plantation-based beekeeping systems by examining productivity performance, honey quality characteristics, stakeholder perceptions, and institutional arrangements. A mixed-methods approach was employed, combining surveys of 60 beekeepers, in-depth interviews with plantation managers and government stakeholders, and laboratory analysis of honey and pollen samples. Quantitative descriptive analysis and qualitative interpretation were used to evaluate production dynamics and value chain constraints. Results indicate an average productivity of approximately 2 kg colony?¹ month?¹, with farm-gate prices averaging around IDR 24,000 kg?¹ across the study areas. At this price level, acacia honey remains positioned primarily as a bulk commodity, which limits its competitiveness in export markets where quality differentiation and certification are increasingly required. The findings suggest that increasing colony numbers and improving productivity could enable economically viable participation in the global honey supply chain. Alternatively, scaling production may support the development of domestic industrial-based honey utilization. Strengthening technical capacity, certification systems, and institutional coordination is therefore essential to enhance competitiveness and support the sustainable development of Indonesia’s plantation-based beekeeping sector

Abstract

Geosesarma noduliferum is a semi-terrestrial freshwater crab endemic to Java, exhibits behavioral activity potentially regulated by daily light-dark cycles. This study was aimed to analyze the circadian rhythm of this crab under laboratory conditions and examine habitat preferences during diurnal and nocturnal periods. Four individuals of 2 males and 2 female crabs were collected from their natural habitat and observed in simulated habitat tanks over three days. Behavioral observations were conducted using focal sampling during six daily sessions (three in diurnal and three nocturnal), and all activities were categorized in active or passive behaviour. The results showed that active behaviors—such as exploration, feeding, and social interaction—were more frequent and prolonged during the nocturnal period, peaking at 11:00 PM. However, passive behaviors such as resting and burial were more prevalent during diurnal. Kruskal-Wallis and Dunn tests indicated significant behavioral differences between day and night periods (p<0.05). Habitat preference also varied; both sexes favoring terrestrial areas at night; during diurnal, males predominantly occupied aquatic areas while females showed a balanced distribution. This study suggests that G. noduliferum exhibits a predominantly nocturnal activity pattern.

Abstract

Honey produced by stingless bees is generally characterized by higher acidity, which is associated with organic acid–producing microorganisms, such as lactic acid and acetic acid–producing. These bacteria can survive in this environment due to their tolerance to high sugar concentrations and low pH. Therefore, this study aimed to explore the presence of lactic acid– and acetic acid–producing bacteria and to analyze their relationship with honey sugar, with a particular focus on the characterization of acetic acid–producing bacteria isolated from Heterotrigona itama honey. This study involved characterizing honey for physicochemical properties and sugar content, and isolating bacteria. Additionally, isolates of acetic acid-producing bacteria were selected on selective media, and molecular identification was performed using 16S rRNA gene sequences. The results show that the proportion of lactic acid– and acetic acid–producing bacteria may influence the sugar content of honey. Honey Hi3 exhibited higher electrical conductivity (EC), total dissolved solids (TDS), moisture content, and acidity compared to the other honey samples. A total of 11 selected isolates showed diverse characteristics and were non-hemolytic. Isolate Hi11 produced 0.3% acetic acid over 48 hours and has optimal acetic acid production in glucose, yeast extract, peptone, and ethanol (GYPE1) medium. Based on 16S rRNA gene sequence analysis, this isolate was identified as the genus Enterobacter. These findings indicate the presence of acetic acid–producing bacteria and their potential contribution to the sour sensory characteristics of H. itama honey in Indonesia.
