Abstract
Acetylation of 4-(4-hydroxy-penyl)-3-butene-2-one by anhydride of acetic acid catalyzed by sulphuric acid results in 4-(4-acetoxy-phenyl)-3-butene-2-one compound, and 4-(4-hydroxy-phenyl)-2-butanone compound as a by product. The first compound alone doesn’t attract fruit flies, but a mixture of the two products attracts male fruit flies. This mixture was tested for its attractancy to the fruit flies in Bantul, Sleman and Kulon Progo regencies, Yogyakarta Special Province; along with Cue and Methyl eugenol lures as comparison. The result showed that the mixture was able to attract four fruit flies species, i.e. Bactrocera albistrigata, B. caudata, B. cibodase, and Bactrocera sp1. One genus found has not been able to be identified to species level. Based on its wing morphometric measures, this species is put under Bactrocera dorsalis complex group.   Reaksi asetilasi terhadap 4-(4-hidroksi-fenil)-3-buten-2-on dengan asam asetat anhidrid berkatalis asam sulfat menghasilkan senyawa 4-(4-asetoksi-fenil)-3-buten-2-on dan hasil samping berupa senyawa 4-(4-hidroksi-fenil)-2-butanon. Senyawa 4-(4-asetoksi-fenil)-3-buten-2-on tidakmemiliki daya pikatterhadap lalat buah, sedangkan campuran kedua senyawa hasil asetilasi tersebut memiliki daya pikat terhadap lalat buah jantan. Uji atraktansi campuran kedua senyawa ini terhadap lalat buah dilakukan di daerah Bantul, Sleman, dan Kulon Progo, Daerah Istimewa Yogyakarta dengan CUE lure dan ME lure sebagai pembanding. Hasil penelitian menunjukkan bahwa campuran senyawa 4-(4-asetoksi-fenil)-3-buten-2-on dan 4-(4-hidroksi-fenil)-2-butanon mampu memikat 4 spesieslalat buah. Empat spesies lalat buah yang terpikat tersebut adalah Bactrocera albistrigata, B. caudata, B. cibodase, dan Bactrocera sp1. Satu Genus Bactrocera tidak teridentifikasi sampai tingkat spesies. Bactrocera sp1. diduga merupakan spesies lalat buah yang belum pernah dideskripsi sebelumnya. Berdasar perhitungan wing morphometric technique, spesies lalat buah tersebut dikelompokkan ke dalam kelompok Bactrocera dorsalis Complex.
