Abstract

This study aims to analyse the diversity and dominance of insect species in maize fields in Caturharjo Village, Sleman District, Yogyakarta. The research was conducted from March to August 2025 on 1,000 m² of maize fields divided into three plots, each measuring 10 × 15 m. Light traps were installed in the centre of each plot, and insects were captured manually (direct capture) every three days. Species diversity was calculated using the Shannon-Wiener Index, dominance using the Simpson Index, and the data were analysed for correlation with abiotic factors. The results showed that the total number of insect individuals in the vegetative phase of maize plants was 19,874 individuals, consisting of 6 orders, 24 families, and 30 species. The largest proportion of insects were predators (33.33%), followed by herbivores (26.67%), maize pests (16.67%), visitors (10%), detritivores (10%), and pollinators (3.33%). The insect diversity index was (H') = 0.83, which was classified as low diversity, and the dominance index was (D) = 0.18, indicating low dominance. The conclusion of this study is that the insect species diversity at the study site was low, with no dominant species found, and a total of 30 insect species found.

Abstract

Fruit flies, Bactrocera spp. (Diptera: Tephritidae), cause severe yield losses in chili production and conventional insecticide-based control raises environmental and resistance concerns. To our knowledge, this study was the first field evaluation in Indonesia to measure the mesh size threshold for an augmentorium that simultaneously retains newly emerged adult Bactrocera insects and allows for the release of naturally occurring parasitoids. This research aimed to identify fruit fly parasitoid species found in chili (Capsicum frutescens L.) fields and recommend mesh sizes that would enable parasitoids to pass through augmentation devices. This study was conducted in Balung District and the Agrofarmaka Laboratory of Jember University, Jember Regency, East Java, Indonesia. Infested chili fruits were placed in augmentorium devices fitted with four mesh diameters 0.5 mm/32 Mesh; 0.75 mm/24 Mesh; 1 mm/16 Mesh; and.5 mm/12 Mesh. Observations were made by identifying parasitoid species and counting the number of emerging parasitoids. The results showed the presence of two parasitoids, Psyttalia fijiensis and Trichopria sp., which successfully emerged from samples and passed through the meshes. P. fijiensis was able to traverse only the largest mesh (1.5 mm), whereas Trichopria sp. passed even the smallest mesh (0.5 mm). Based on these results, the 1.5 mm (12-mesh) augmentorium optimizes its dual function as a sanitation tool for fruit infested with fruit flies and as a parasitoid augmentation in chili cultivation. This evidence supports the practical application of augmentorium as a landscape-scale celement in integrated pest management for Bactrocera spp. is supported by this evidence.

Abstract

Cigarette smoke generates free radicals that can cause various respiratory disorders. Red spinach (Amaranthus tricolor L.) is a plant rich in antioxidants, which may help neutralize free radicals produced by cigarette smoke exposure. This study aimed to evaluate the protective effects of red spinach ethanol extract on the trachea of Wistar rats exposed to cigarette smoke. Twenty-four male Wistar rats were randomly assigned to four groups: K (distilled water), KN (cigarette smoke exposure), P1 (cigarette smoke exposure with 200 mg/kg BW extract), and P2 (cigarette smoke exposure with 400 mg/kg BW extract). Treatments were administered daily for 21 consecutive days. On day 22, the rats were euthanized, and their tracheas were collected for histological analysis. The tracheal tissues were processed using the paraffin embedding method and stained with hematoxylin and eosin. The evaluated parameters included epithelial cell height, tracheal lumen diameter, and goblet cell number. Data were analyzed using one-way ANOVA followed by Duncan’s post hoc test, with significance set at p < 0.05. Results demonstrated that exposure to cigarette smoke (KN group) significantly disrupted the tracheal histological structure (p < 0.05). However, administration of 400 mg/kg BW red spinach ethanol extract (P2 group) exhibited a protective effect by preserving epithelial cell height, lumen diameter, and goblet cell number comparable to those of the control group (K). In conclusion, red spinach ethanol extract at a dose of 400 mg/kg BW effectively protects the tracheal structure of Wistar rats against cigarette smoke-induced damage by maintaining epithelial cell height, lumen diameter, and goblet cell number at near-normal levels.

Abstract

Spodoptera frugiperda Smith is a major invasive pest of maize and has also been reported attacking other host plants, including rice. As a migratory pest with high reproductive capacity, the population dynamics of S. frugiperda are influenced by cropping systems and host plant availability. Accurate population monitoring is a key component of integrated pest management (IPM). However, the performance of different trap types under varying agroecosystems has not been fully understood. This study aimed to evaluate the performance of different trap types (pheromone, light, and pheromone–light combination traps) in detecting S. frugiperda populations in maize and rice fields under different agroecosystem conditions. The study was conducted at four locations representing distinct agroecosystem conditions. Each location consisted of three field plots as independent replications. The number of adults captured per trap per week was used as an indicator of trap performance. The results showed that S. frugiperda populations were significantly higher in maize fields than in rice fields (p < 0.0001). A significant interaction was found between trap type and agroecosystem condition (p < 0.001). Pheromone traps recorded the highest captures under high population conditions, whereas light and combination traps performed relatively similarly under low population conditions. Light traps captured more non-target insects than pheromone traps. These findings indicate that the performance of S. frugiperda traps is context-dependent and should be adapted to the cropping system to support IPM-based monitoring strategies.
