Relative preference of peach fruit fly, Bactrocera zonata (Saunders) (Diptera: Tephritidae) to some fruit and vegetables under laboratory conditions.

摘要

Thirteen species of the available fruit and vegetables were chosen for this study under the laboratory conditions using a new choice chamber. Statistical analysis of obtained data indicated that guava fruit was the most preferable host according to an ascending sorted list of attraction percentages based on the number of flies attracted to guava. Lemon, zucchini, grapefruit and plum fruits were the least attractiveness, whereas, cantaloupe, apple and pear were found to be the highly preferable fruits. The rest of examined fruits, such as peach, fig, mango, orange and cucumber, had a moderate preferable level. This wide range of response, in the present work, may be attributed to the large number of volatile substances that emanate from fruit inducing insect responses. The results of the present study and related subjects were discussed.
