“…The results of the genetic analysis of S. frugiperda spread in West Sumatra belong to two groups. Genetically, S.frugiperda in West Sumatra is very closely related to other Asian countries such as Japan and China [12]. S. frugiperda was also found in Lampung and showed genetic similarities with other populations [13].…”

Maize is commonly planted in monoculture. However, in several areas of West Sumatra, it is also cultivated as polyculture side-by-side with oil palm. The study aimed to investigate the important pests that attacked maize plants in oil palm plantations in Pasaman, West Sumatra. This research was conducted in existing and replanting oil palm plantations. Insect pests data collection was purposive random sampled from represented plots of maize plants that were attacked by pests. Five sample plots of 1x1 m2 were taken for assessing insect pests incidence. The average number of maize plant stalks observed 32. Observations were made on the condition of the maize and oil palm agroecosystem, species and populations, and symptoms of insect pests that attack maize. The result showed that Stenocranus pacificus and Spodoptera frugiperda were the most dominant insect pests. The insects damaged the leaves and stems of maize plants. Stenocranus pacificus population was 4.45 individuals/plants, and Spodoptera frugiperda was 1.7 individuals/plants. The maize in West Pasaman is mostly planted on oil palm plantations consisting of monoculture and in oil palms that would be replanted. It was found that two insect pest species were dominant attackers, i.e., Symptoms of the attacks were seen on the leaves and stems of the plants.

O Objective: To perform the first molecular characterization of the barcoding COI region of the S. frugiperda found in Tabasco and to test whether it can reliably identify the strain detected in the said state. Design/Methodology/Approach: We collected S. frugiperda specimens using four pheromone traps placed in corn plots. Subsequently, we implemented DNA extraction, PCR with LCO-L/HCO-L primers, and the sequencing of six individuals captured in the traps. Results: After aligning the sequences, we developed a phylogenetic tree, determining that S. frugiperda belongs to the rice strain (RS). Implications: Identifying the S. frugiperda strain is necessary for management purposes, since different strains may require different control methods. Findings/Conclusions: Our study revealed that the isolates from Chontalpa, Tabasco, Mexico, match the RS fall armyworm reported in other latitudes. Consequently, this is the first report to identify this strain of S. frugiperda in Tabasco. Our findings are relevant because this species can potentially become a pest in sugarcane- and rice-growing areas of the state.

Jagung adalah sumber pakan utama pada ternak unggas, dengan komposisi dalam ransum mencapai 58%. Tingkat kebutuhan jagung sangat ditentukan oleh populasi dan jenis unggas. Telah dilakukan analisis untuk mengetahui produksi dan kebutuhan jagung per tahun. Jumlah atau produksi yang harus ditingkatkan untuk memenuhi kebutuhan pakan unggas di Sumatera Barat. Penelitian dilakukan menggunakan data sekunder dari Badan Pusat Statistik (BPS) Sumatera Barat tahun 2020. Penelitian menggunakan metoda deskriptif kuantitatif. Pengamatan dilakukan di semua Kabupaten/Kota di Sumatera Barat, yaitu; jenis dan populasi unggas, produksi per kabupaten/kota dan kebutuhan jagung sebagai pakan unggas. Data dianalisis dengan menggunakan excel for window dan ditampilkan dalam bentuk gambar dan tabel. Hasil analisis menunjukan bahwa rata rata kebutuhan jagung per tahun di Sumatera Barat untuk pakan ternak unggas adalah 3.774,1 ton/hari setara dengan 1.377.546,5 ton/tahun atau 1,38 juta ton/tahun. Sedangkan rata rata produksi jagung per tahun hanya 925 564 ton atau 0,9 juta ton/tahun. Berdasarkan hasil analisis kebutuhan dan produksi, jagung belum mencukupi untuk kebutuhan pakan ternak unggas. Perlu peningkatan produksi jagung untuk pakan ternak unggas di Sumatera Barat,sebanyak 0,48 juta ton/tahun.
