Bactrocera carambolae is an important pest on fruit trees and vegetables. One control measure practiced, which is considered relatively safe for human and other organisms, is the use of attractant food bait for fruit flies. One of such attractant baits is the processed beer waste. This kind of attractant bait has inspired the potency of other wastes to be observed as attractant. The study was proposed to observe several different wastes, i.e. cocoa, tofu, fish, brem (a Balinese liquor made of rice), milk, molasse, arrack, vinase and sludge (waste of sugar processing) as fruit fly attractants. Beer waste was used as a control. The study consisted of three phases. The first phase was to test the wastes� potency in attracting B. carambolae. In the second phase, the selected wastes with the highest attractancy were analyzed to identify its potential as attracting compounds. The third phase was done by potentiating the selected wastes. The results of the first phase showed that both male and female of B. carambolae were more attracted by processed wastes than water. The attractancy test of different wastes, from the strongest to the weakest were respectively cocoa, brem, tofu, fish, sludge, milk, arrack, mollase, and vinase. The second phase was focused on the identifying of the attractant compounds in processed cacao and beer wastes. The chemical analysis showed that the processed cacao waste contains 12.98% proteins, sugar (1.17% reducing sugar and 0.12% sucrose), (46.45 mg/100g) ammonia and six complex volatile attractant compounds. The processed beer waste contents were 12.45% proteins, (199.13 mg/100g) ammonia and 16 complex volatile attractant compounds. The third phase was potentiating the processed cocoa waste by adding 10% ammonium acetate solution, 10% sucrose solution, and a mixture of the two. It was shown that the processed cocoa waste added with 10% ammonium acetate solution was more attractive to B. carambolae compared to those added with the 10% sucrose solution or mixture of 10% ammonium acetate and 10% sucrose. Addition of 10% ammonium acetate solution can improve the attractiveness of 18% males and 12% females of B. carambolae compare with processed cocoa waste only.
