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.

Abstract

Rainforest conversion into monoculture plantations has decreased tree canopy cover and insect diversity, including Diptera. Diptera is a group of insects that play a crucial role in maintaining the balance of ecosystems. This study aimed to assess the impact of forest conversion to plantations on the diversity and composition of Diptera across four landuse types in Jambi, Sumatra. Diptera sampling was conducted using canopy fogging in two landscapes: Bukit Duabelas National Park and Harapan Rainforest. In each landscape, four land use types were determined: forest, jungle rubber, rubber plantation, and oil palm plantation. A total of 13,513 Diptera individuals were collected, representing 39 families, 169 genera, and 399 species. The dominant family is Cecidomyiidae, and the dominant species is Procontarinia sp. 01. The highest abundance and species richness was found in forest, followed by jungle rubber. The lowest abundance was found in oil palm plantations, while the lowest species richness was found in rubber plantations. ANOVA test results indicated that different land use type significantly influenced Diptera abundance and species richness, whereas landscape had no significant effect. Diptera composition was influenced by land use type, landscape, and the interaction between land use type and landscape. Diptera composition in forest and jungle rubber showed the highest similarity, while the lowest similarity was in forest and oil palm plantation. This composition change was driven by species turnover. In addition, land conversion also caused a shift in dominance, with forests dominated by Cecidomyiidae, then dominance shifted to Ceratopogonidae in monoculture plantations.

Abstract

A nanoemulsion formulation of a mixture of Piper aduncum extract and Cymbopogon nardus hydrosol was evaluated for its effectiveness against the major broccoli pests, Crocidolomia pavonana and Plutella xylostella. The study was conducted in Alahan Panjang, West Sumatra, using a completely randomized design with four treatments (the nanoemulsion formulation, Bacillus thuringiensis, cypermethrin, and a control) and seven replications. Treatments were applied weekly from 21 to 70 days after planting (DAP). Larval population density and plant damage were recorded, and the data were analyzed using analysis of variance (ANOVA) followed by a least significant difference (LSD) test at a 5% significance level. Infestation by P. xylostella occurred earlier at 21 DAP, whereas infestation by C. pavonana began at 28 DAP. Overall, the population density of P. xylostella was higher than that of C. pavonana. The nanoemulsion formulation exhibited insecticidal activity, although its effectiveness was lower than that of cypermethrin and B. thuringiensis. The effectiveness rates against C. pavonana were 71.49%, 48.54%, 33.33%, and against P. xylostella were 73.49%, 60.88%, and 57.52% for cypermethrin, B. thuringiensis, and the nanoemulsion formulation, respectively.

Abstract

Fipronil merupakan insektisida yang banyak digunakan dalam pengendalian hama wereng batang cokelat (WBC) (Nilaparvata lugens Stal.) di Indonesia. Penggunaan fipronil di tingkat petani seringkali tidak sesuai anjuran sehingga menimbulkan kekhawatiran terjadinya resurjensi. Penelitian ini bertujuan untuk mengkaji pengaruh konsentrasi subletal dan frekuensi aplikasi insektisida fipronil terhadap peningkatan populasi WBC pada dua varietas padi, yaitu IR64 dan Ciherang. Sampel WBC yang digunakan berasal dari Kabupaten Karawang, Jawa Barat. Penelitian terdiri atas uji toksisitas untuk menentukan konsentrasi subletal fipronil, yaitu pada tingkat LC15, LC25, dan LC40, air sebagai kontrol. Masing-masing perlakuan diaplikasikan sebanyak 1, 2, dan 3 kali dengan selang waktu 5 hari antar aplikasi. Hasil penelitian menunjukkan bahwa paparan konsentrasi subletal (LC15, LC25, dan LC40) memicu fenomena hormoligosis yang ditandai dengan peningkatan signifikan pada persentase penetasan telur di semua tingkat konsentrasi dibandingkan dengan kontrol. Persentase penetasan telur tertinggi terdapat pada perlakuan LC15  dengan varietas Ciherang, yakni 82,55%. Meskipun peningkatan konsentrasi dan frekuensi aplikasi (1–3 kali) secara linear meningkatkan mortalitas nimfa hingga 94,44% pada perlakuan LC40, namun pada dosis rendah LC15, peningkatan frekuensi aplikasi justru menstimulasi lonjakan populasi nimfa F1. Populasi nimfa tertinggi terdapat pada varietas Ciherang dengan perlakuan LC15 dua kali aplikasi, yakni 1197,33 individu. Temuan ini mengonfirmasi bahwa aplikasi fipronil pada tingkat subletal, terutama pada varietas rentan, tidak hanya gagal mengendalikan WBC tetapi justru memicu resurjensi melalui peningkatan keberhasilan penetasan telur dan stimulasi reproduksi generasi berikutnya.

Abstract

Apis dorsata Fabricius is a giant forest honey bee with a wide distribution that includes Indonesia. South Sumatra, Belitung, and West Kalimantan exhibit distinct geographic and ecological characteristics that may influence the morphometric variations of this species. This study aimed to analyze the similarities and differences across various morphometric parameters of A. dorsata colonies from these three regions. A traditional morphometric approach was conducted to measure 23 morphometric parameters. A total of 120 individuals from 12 A. dorsata colonies originating from South Sumatra, Belitung, and West Kalimantan were examined. The results indicated that 12 of the 23 parameters (52.2%) differed significantly among populations. Populations from South Sumatra generally exhibited larger structural dimensions across several head, thorax, and wing parameters, whereas the Belitung populations demonstrated higher values for proboscis length and antennal socket distance. Multivariate analysis (NMDS and ANOSIM) revealed statistically significant, albeit weak, differentiation among the populations. Overall, these findings indicate the presence of localized morphometric variations across the islands, although the degree of morphological differentiation remains relatively low.

Abstract

Malaria remains a public health burden in tropical coastal regions, where complex environmental conditions support vector populations and increase transmission risk, particularly among vulnerable groups. Understanding the environmental characteristics of Anopheles spp. breeding habitats is essential for explaining vector distribution and informing control strategies. This study analyzed the environmental characteristics of potential Anopheles spp. breeding habitats in the coastal areas of Gaura Village. An observational descriptive survey with a cross-sectional approach was conducted using purposive spatial sampling across two survey rounds, measuring physical, chemical, and biological variables. A total of 12 breeding sites were identified, with confirmed vectors including Anopheles sundaicus (Rodenwaldt), An. subpictus Grassi, and An. barbirostris van der Wulp. Larval densities peaked in confined anthropogenic microhabitats, particularly buffalo wallows (3.5 larvae/dip) and footprints (3.1 larvae/dip). The habitats exhibited wide physicochemical variability (temperature 29.0–39.4°C; pH 7.3–9.2; salinity 0–20‰). Principal component analysis (PCA) explained 61.3% of total variation, distinguishing habitats along two gradients: PC1 (34.3%), driven by structural area, dissolved oxygen, and light intensity; and PC2 (27.0%), driven by pH and salinity. All highly productive habitats were located within 512 meters of residential areas, placing communities within the active flight range of vectors. These findings indicate that malaria transmission risk in coastal Gaura Village is driven by environmentally diverse yet spatially clustered larval habitats, particularly small, human-proximal sites associated with livestock, highlighting the need for targeted larval source management.

Abstract

The fall armyworm (Spodoptera frugiperda Smith) is an invasive pest that attacks corn crops and has the potential to cause crop failure. One effective strategy is to utilize natural enemies, specifically parasitoids. This study aimed to identify parasitoid species and determine parasitism rates in S. frugiperda across three corn fields in Rasau Jaya I Village, West Kalimantan. Larval samples were collected from 50 plants per field using purposive sampling with a W-shaped scouting pattern, then reared in the laboratory. The results revealed the presence of the parasitoid Chelonus formosanus Sonan with an average parasitism rate of 11.24%, as well as differences in the number of antenna segments compared to previous studies. Chelonus formosanus has the potential to be developed as a biological control agent.

Abstract

Wallacetrigona incisa (Sakagami & Inoue) and Tetragonula sapiens (Cockerell) are two stingless bee species widely cultivated for honey production in West Sulawesi, Indonesia. Yet, no comparative physicochemical data on their honey from this region exist. This study compared the physicochemical properties of W. incisa honey from a highland meliponary (1340 m a.s.l) and T. sapiens honey from a lowland meliponary (9 m a.s.l), and documented the flowering plant assemblages and abiotic conditions at each site. Ten parameters were assessed, including water content, ash, glucose, reducing sugar, fat, vitamins A and C, and antioxidant activity (IC50). W. incisa honey had higher water content (28.61%), glucose (61.18%), and vitamin C (374.61 µg/g) than T. sapiens (22.45%, 44.86%, 270.77 µg/g, respectively). T. sapiens honey had higher ash content (0.91% vs. 0.18%) and a higher IC50 value (562.81 vs. 423.40 ppm), indicating weaker antioxidant activity. These differences may be attributed to the contrasting altitudinal environments, including ambient humidity at the highland site (77.5% vs. 69.5% RH) and differences in surrounding vegetation (24 vs. 12 flowering plant species). W. incisa honey complied more closely with the Indonesian National Standards (SNI 8664:2024) threshold than T. sapiens honey. Further studies with replicated sampling are needed to confirm these preliminary findings.
