Abstract

Salah satu musuh alami yang dapat digunakan untuk mengendalikan populasi Spodoptera frugiperda di lapangan adalah parasitoid. Parasitoid yang telah diketahui potensial dalam mengendalikan populasi S. frugiperda adalah Telenomus remus. Tujuan dari penelitian ini yaitu untuk menganalisis persebaran, tingkat parasitasi, dan tingkat parasitisme T. remus pada telur S. frugiperda di Kabupaten Sleman, Yogyakarta. Lahan yang digunakan dalam pengambilan sampel telur ditentukan dengan metode stratified random, sedangkan pengambilan sampel pada lahan penelitian dilakukan dengan metode purposive. Sampel yang diambil berupa telur S. frugiperda dan dipelihara sampai telur menetas menjadi larva atau keluar parasitoidnya. Baik telur yang menetas ataupun tidak kemudian dihitung untuk menentukan tingkat parasitasi dan tingkat parasitisme T. remus. Analisis data yang digunakan dalam penelitian ini adalah analisis korelasi. Hasil penelitian menunjukkan bahwa T. remus tersebar pada 17 kecamatan di Sleman dengan persebaran tertinggi di Sleman dan Pakem, sedangkan persebaran terendah di daerah Tempel, Minggir, dan Ngaglik. Tingkat parasitasi T. remus terhadap telur S. frugiperda masuk kedalam kategori tinggi cenderung sangat tinggi, sedangkan untuk Tingkat parasitisme mencapai 86%. Berdasarkan hasil ini, dapat disimpulkan bahwa persebaran dan kemampuan parasitasi T. remus terhadap telur S. frugiperda di Sleman tergolong baik. Sehubungan dengan hal tersebut untuk mendukung efektivitas pengendalian hayati ini, perlu dilakukan upaya pengurangan penggunaan pestisida kimia, misalnya melalui penerapan pengendalian hama terpadu (PHT), penggunaan pestisida selektif yang ramah musuh alami, serta peningkatan pelatihan petani terkait konservasi agen hayati.

Abstract

The high number of filariasis cases in Indonesia requires efforts to control the population of Culex quinquefasciatus larvae. This study aims to analyse the concentration that is effective in killing Cx. quinquefasciatus larvae for 48 hours, and to analyse the LC50 and LT50 values of bandotan leaf extract within 48 hours. Bandotan leaves were collected from Jamblang village, Sleman, Yogyakarta. The leaves were extracted using 96% ethanol, diluted into five concentrations repeated 5 times. Third instar larvae of Cx. quinquefasciatus were obtained from the Salatiga Environmental Health Laboratory (BBLKL). Larval mortality was analysed using Kruskal-Wallis test and LC50 and LT50 probit analysis. The results obtained showed that 96% ethanol extract of bandotan leaves at concentrations of 1% (positive control) and 9% had an effect on larval mortality, with an LC50 value obtained of 3.88%. The LT50 values at concentrations of 0%, 1%, 3%, 5%, 7%, and 9% were 0 hours; 2.64 hours; 146.90 hours; 102.43 hours; 79, 24 hours; and 53.83 hours. The conclusion of this study is that 96% ethanol extract of bandotan leaves at the concentration used in this study does not have the potential to be used as a larvicide against Cx. quinquefasciatus.

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

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.
