| Abstract | The pumpkin fruit fly (Zeugodacus tau) is an important agricultural pest in many regions of the world. It has more than 91 economic host-plant species, particularly in the family Cucurbitaceae. The infestation of this fruit fly species has caused damage to quality and quantity of agricultural products. The host preference of the pumpkin fruit fly with choice and no choice tests using cucumber, pumpkin and bitter gourd as host-plants were performed under laboratory conditions. The results demonstrated that the number of pupae and adult pumpkin fruit fly found in the three cucurbit host-plants were significantly different (P < 0.05). The highest number of pupae and emerged adults for the choice test were found in pumpkin, followed by cucumber and bitter gourd, respectively. For the no choice test, the highest number of pupae and emerged adults were observed in cucumber, followed by pumpkin and bitter gourd, respectively. The host preference of the pumpkin fruit fly in this study indicated that female fruit flies use vision and olfactory cues to locate the host-plant. They were attracted by cucumber odor and yellow color of pumpkin. In addition, the nutrient compositions of the host-plant also affect fruit fly performance. Tephritid fruit flies preferred host with high concentration of water, carbohydrate and fat. In conclusion, the study on host preference of the pumpkin fruit fly revealed factors affecting host-plant selection that can be used as information for pest management for the imported and exported cucurbit products. |
