      Abstract
      The rice stem borer is one of the most important rice pests in Indonesia. Three species of rice stem borer are found in Subang Regency, including the yellow rice stem borer (Scirpophaga incertulas), the striped rice stem borer (Chilo suppressalis), and the pink rice stem borer (Sesamia inferens). This study aims to determine the population dynamics of rice stem borer species in Kiarasari Village, Compreng District, Subang Regency. Rice stem borers were collected using an Insect Light traps 0.4 watt LED trap lamp, then counted and identified to determine the species. The research was conducted from January to October 2022. Lightrap was placed in three parts of the rice fields based on the compass point, west, east and north. The dominant rice stem borer was the yellow rice stem borer (92.2%). Other types of rice stem borer are pink rice stem borer (4.4%) and striped rice stem borer (3.5%). There was a difference in the average number of rice stem borer adults caught in each wind direction. The number of catches of the yellow rice stem borer was higher when the lamp traps were placed in the north, west and east directions compared to the striped rice stem borer and the pink rice stem borer. The development of rice stem borer populations can be affected by wind speed, temperature, and humidity.
       
      Penggerek batang padi merupakan salah satu hama tanaman padi yang penting di Indonesia. Penggerek batang padi yang ditemukan di Kabupaten Subang ada tiga jenis yaitu penggerek batang padi kuning (Scirpophaga incertulas), penggerek batang padi bergaris (Chilo suppressalis), dan penggerek batang padi merah muda (Sesamia inferens). Penelitian ini bertujuan untuk mengetahui dinamika populasi spesies penggerek batang padi di Desa Kiarasari, Kecamatan Compreng, Kabupaten Subang. Penggerek batang padi dikumpulkan dengan lampu perangkap LED Insect Lightrap 0,4 watt, kemudian dihitung dan diidentifikasi untuk menentukan spesiesnya. Penelitian dilakukan pada bulan Januari hingga Oktober 2022. Lightrap ditempatkan di tiga bagian pesawahan berdasarkan arah mata angin, yaitu barat, timur, dan utara. Penggerek batang padi yang dominan adalah penggerek batang padi kuning (92,2%). Jenis penggerek batang padi lainnya adalah penggerek batang padi merah jambu (4,4%) dan penggerek batang padi bergaris (3,5%). Terdapat perbedaan rata-rata jumlah imago penggerek batang padi yang tertangkap pada setiap arah mata angin. Jumlah tangkapan penggerek batang padi kuning lebih banyak tertangkap pada semua penempatan lampu perangkap dibandingkan dengan penggerek batang padi bergaris dan penggerek batang padi merah jambu. Kecepatan angin, suhu, dan kelembapan udara dapat berpengaruh terhadap perkembangan populasi penggerek batang padi.
