Effect of application method of oil distilled from Melaleuca bracteata leaves and methyl eugenol on the trapping of fruit fly Bactrocera dorsalis

Research has been conducted at farmer's fruit garden in Cilebut area, Bogor during 1997-1998. The objective is to know the effect of some application techniques of oil distilled from Melaleuca bracteata leaves on trapping fruit fly. Research consisted of three activities, those were the effect of some techniques of application on trapping fruit flies (1) weekly, (2) in two weeks and (3) the effect of some concentration of methyl eugenol (ME) on trapping fruit fly. All treatments were hung at the fruit trees as high as 1.5 m. Observations were done in the number and gender of fruit flies trapped weekly and two weekly. Result revealed that melaleuca distilled oil can be applied either by dropping into water into cotton ball. Melaleuca leaves distilled oil should be applied once in two weeks, since its effectiveness lasted for two weeks only. The minimum concentration of methyl eugenol which could trap fruit flies effectively was 57 percent Penelitian telah dilakukan di kebun buah-buahan petani di desa Cilebut, Bogor dalam kurun waktu 1997-1998. Penelitian bertujuan untuk mengetahui pengaruh cara aplikasi minyak suling daun melaleuca (Melaleuca bracteata) terhadap daya pikat lalat buah. Penelitian terbagi menjadi tiga kegiatan, yaitu pengaruh cara aplikasi minyak suling daun melaleuca dalam memerangkap lalat buah (1) secara mingguan (2) selama dua minggu dan (3) pengaruh konsentrasi metil eugenol (ME) terhadap daya lalat buah. Semua perlakuan ditempatkan dalam botol mineral bekas yang digantungkan pada pohon setinggi +-1,5 m. Pengamatan dilakukan terhadap jumlah dan jenis kelamin lalat terperangkap setiap minggu dan setiap dua minggu. Hasil penelitian menunjukkan bahwa minyak suling melaleuca dapat diaplikasikan baik secara penetesan ke dalam air maupun pada kapas. Penetesan minyak perlu dilakukan setiap dua minggu, mengingat daya pikatnya sudah menurun pada minggu ke dua. Konsentrasi metil eugenol minimum yang efektif memerangkap lalat buah adalah 57 persen
