Evaluasi Efektivitas Pengendalian Hama Oryctes rhinoceros pada TBM di PT Surya Intisari Raya 1

Abstract

Oryctes rhinoceros merupakan salah satu hama utama pada tanaman kelapa sawit yang dapat menurunkan pertumbuhan dan produktivitas tanaman. Penelitian ini bertujuan mengevaluasi efektivitas ferotrap dan boxtrap sebagai metode monitoring populasi O. rhinoceros. Penelitian dilaksanakan selama 30 hari dengan pengamatan setiap tiga hari. Data yang diamati meliputi jumlah imago tertangkap, jumlah tangkapan kumulatif, serta efektivitas penangkapan berdasarkan catch per trap (CPT) dan catch per trap per day (CTD). Perbedaan jumlah tangkapan dianalisis menggunakan uji Mann–Whitney. Hasil penelitian menunjukkan bahwa ferotrap menangkap imago lebih banyak dibandingkan boxtrap, dengan jumlah tangkapan kumulatif masing-masing 564 ekor dan 45 ekor. Hasil uji Mann–Whitney menunjukkan perbedaan nyata antara kedua metode (p < 0,001). Nilai CPT dan CTD boxtrap juga lebih tinggi dibandingkan ferotrap. Hasil penelitian menunjukkan bahwa boxtrap lebih efektif dibandingkan ferotrap sebagai metode monitoring populasi O. rhinoceros pada kondisi lokasi penelitian.

Oryctes rhinoceros is one of the major pests of oil palm, causing damage that reduces plant growth and productivity. This study aimed to evaluate the effectiveness of pheromone traps and barrier nets as monitoring methods for O. rhinoceros populations. The study was conducted over 30 days with observations every three days. The observed variables included the number of adults captured, cumulative catches, and trapping efficiency based on catch per trap (CPT) and catch per trap per day (CTD). Differences between the two monitoring methods were analyzed using the Mann–Whitney test. Pheromone trap captured more adults than boxtrap, with cumulative catches of 2,221 and 564 individuals, respectively. The Mann–Whitney test showed a significant difference between the two methods (p < 0.001). Barrier nets also produced higher CPT and CTD values than pheromone traps. These findings indicate that barrier nets were more effective than pheromone traps for monitoring O. rhinoceros populations under the conditions of this study.
