| Summary: | 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. |
