Abstract


The effectiveness of a synthetic-pheromone trap with active ingredient of ethyl-4-methyloctanoate in catching adults of Oryctes rhinoceros was believed to be influenced by the trap color. A RCBD trial with single factor and three block replicates was conducted during September to October 2008 at Oil-Palm-Trial Station at PTPN III, Labuhan Batu District, North-Sumatera Province. The single factor was trap color i.e. orange, green, white, blue, red, yellow, and pink. Results showed that total numbers and sex ratios of collected O. rhinoceros adults were not significantly influenced by the trap color. The total numbers of collected O. rhinoceros adult during 30 days on color of orange, green, white, blue, red, yellow, and pink were 136, 177, 126, 155, 129, 114, and 113 individuals with sex ratios ♂/♀ 0.47, 0.52, 0.62, 0.50, 0.60, 0.49, and 0.54, respectively. The synthetic pheromone significantly attracted more O. rhinoceros female (65%) rather than the male one (35%).

 

Keefektifan perangkap feromon sintetik berbahan aktif ethyl-4-methyloctanoate dalam menangkap imago Oryctes rhinoceros diyakini dipengaruhi oleh warna perangkap tersebut. Percobaan RCBD faktor tunggal dengan tiga blok ulangan dilakukan pada bulan September sampai dengan Oktober 2008 di kebun penelitian kelapa sawit PTPN III, Kabupaten Labuhan Batu, Provinsi Sumatera Utara. Faktor tunggal tersebut yakni warna perangkap meliputi oranye, hijau, putih, biru, merah, kuning, dan pink. Hasil penelitian menunjukkan bahwa warna perangkap tidak berpengaruh signifikan terhadap hasil tangkapan dan sex ratio imago O. rhinoceros. Total imago O. rhinoceros yang tertangkap selama 30 hari pada warna oranye, hijau, putih, biru, merah, kuning dan pink sebanyak 136, 177, 126, 155, 129, 114 dan 113 dengan sex ratio ♂/♀ 0,47; 0,52; 0,62; 0,50; 0,60; 0,49 dan 0,54. Feromon sintetik secara signifikan lebih banyak menarik imago betina (65%) daripada yang jantan (35%).
