Abstract

Here, we provide the first record of the chafer beetle genus Epholcis Waterhouse, 1875 from the Moluccan Islands, Indonesia. We describe four new species: E. acutus sp. nov., E. arcuatus sp. nov., E. cakalele sp. nov., and E. obiensis sp. nov. A lectotype is designated for Maechidius moluccanus Moser, 1920, which is redescribed and transferred to the genus Epholcis as E. moluccanus (Moser) comb. nov.

Abstract

Vespa affinis is a hornet with wide geographical distribution, occurring across the Indonesian Archipelago (Sumatra, Java, Kalimantan, Sulawesi, the Moluccas, and Papua) but excluding the Lesser Sunda Islands. Species with wide distribution typically show morphological variations that may differ across their range. This study aims to provide a detailed description of island-to-island diversity in morphometric characters and marking patterns among Indonesian populations of V. affinis. A total of 18 morphometric characters and 18 color patterns were analyzed. Principal Component Analysis (PCA) and Linear Discriminant Analysis (LDA) were employed to distinguish variations in morphometric data. Marking pattern data were analyzed using the hierarchical clustering, to understand the clustering and relationship of marking patterns. The morphometric similarity recorded across the Indonesian archipelago suggests limited morphometric divergence among the populations. The marking patterns of V. affinis showed considerable variation across its geographical range, with brighter coloration in populations from eastern Indonesia compared to those from Sundaland.

Abstract

The increasing use of plastic materials in daily life has led to a rise in plastic waste, contributing significantly to environmental pollution. This study aims to analyze the characteristics of insects that contribute to the eco-friendly degradation of plastic waste and to evaluate the rate of plastic waste degradation and the waste reduction index (WRI) achieved through insect larvae. The research uses a Randomized Factorial Design, investigating plastics such as styrofoam blocks, low-density polyethylene, polyurethane, polystyrene, and a control. The parameters examined include insect characteristics, larval length and weight, degradation rate, and WRI. Both Zophobas atratus and Tenebrio molitor exhibit the potential for the bioconversion of plastic waste. The weight of T. molitor larvae ranges from 0.07-0.09g, while Z. atratus larvae weigh between 0.51 and 0.60g. The WRI is directly proportional to the reduction rate, with higher reduction rates corresponding to higher WRI values. The results showed that the control using Z. atratus and T. molitor larvae achieved the highest WRI values among all treatments. Among the plastic types studied, styrofoam blocks showed the highest WRI value, indicating that a feeding rate of 1g of plastic per larva per day is optimal for efficiently reducing plastic waste. This supports circular economy initiatives for companies developing insect-based proteins for food, feed, and natural products while advancing sustainable development goals.

Abstract

This study examines the potential for rearing Apis cerana Fabricius honey bees in Taman Kehati Kiarapayung, West Java. Observations were conducted by installing 39 beehive in various locations and observing the flora that serve as bee food sources. A total of 50 plant species from 24 families were identified as bee food sources. Out of the 39 beehive, only 4 were successfully inhabited by bee colonies, showing a success rate of 10.3%. The observed colony growth ranged from 3 to 9 honey combs per hive. The main challenges in cultivation are the decrease in food availability during the dry season with very low rainfall, and pest disturbances such as wax moths (Galleria mellonella), wasps (Vespa sp.), and ants (Formicidae). The results of this study indicate that A. cerana beekeeping has the potential to be implemented in specific locations with sufficient food availability and effective pest management. This potential can serve as an additional source of income for the local community and support environmental conservation efforts by utilizing biological resources and biodiversity in a non-destructive manner at conservation sites.
