摘要：The fruit fly Bactrocera spp. (Diptera: Tephritidae) is one of the important pests attacking crops of fruits and vegetables. In the laboratory, B. carambolae was attracted by the processed cocoa waste. The results of field trials have not been satisfactory yet, because the processed cocoa waste was easily damaged. The purpose of the study wast to examine the response of Bactrocera to the bait made of processed cocoa extract waste containing preservatives. The preservatives used were: Sodium chloride (NaCl), sodium benzoate (C7 H5NaO2) andpotassium sorbate (C6H7KO2). The concentration of each preservative was 0.1%; 0.2% and 0.3%. A one-week observation was made. The result showed that there was no significant difference on the durability of the preserved waste and the non-preserved waste. This can be seen from the physical properties (color and texture). However, there was difference in odor. The non-preserved waste tended to produce unpleasant smell than the preserved waste. This odor affected the capability to attract the flies to the processed cocoa waste. The Bactrocera was highly responsive to the waste containing preservative 0.3% sodium chloride, followed by 0.2% potassium sorbate and 0.1% sodium benzoate.
