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.

Abstract

Bagworm (Metisa plana Walker) is a major defoliating pest of oil palm, causing significant yield losses during outbreaks. Biological control using predatory insects offers an environmentally sustainable alternative to chemical insecticides. This study evaluated the predatory performance of Sycanus sp. against M. plana larvae and assessed the effect of predator density on prey suppression under laboratory conditions. A completely randomized design was used with five predator-density treatments (1, 2, 3, 4, and 5 predators per 10 larvae) and ten replications. Predator performance was evaluated based on prey-search duration, handling time, larval mortality, and prey consumption. The initial prey-search duration ranged from 2.11 to 2.25 min, while subsequent searches ranged from 1.69 to 2.04 min. Prey-handling time remained relatively constant across treatments (58.1–59.1 min). Predation by Sycanus sp. substantially reduced M. plana populations within three days, with the highest mortality occurring on the first day after predator introduction. Predator density significantly increased prey consumption, which rose from 1.26 ± 0.21 larvae at one predator to 4.43 ± 0.19 larvae at five predators. A strong positive relationship was observed between predator density and prey consumption (y = 0.795x + 0.451; R² = 0.9531). Although the highest prey suppression occurred at the greatest predator density, a ratio of two Sycanus sp. adults per ten M. plana larvae provided a favorable balance between prey suppression and predator deployment efficiency. These findings support the potential use of Sycanus sp. as a biological control agent in sustainable oil palm integrated pest management programs.
