Trapping the African fig fly (Diptera: Drosophilidae) with combinations of vinegar and wine
Florida Entomologist 97 (1), 85-89
Abstract: The African fig fly, Zaprionus indianus Gupta (Diptera: Drosophilidae), is an invasive fruit pest that has spread rapidly through much of the eastern United States. Tests were conducted in southern Florida that recorded the response of Z. indianus to baits that included Merlot wine, rice vinegar, ethanol and acetic acid, alone and in combination. The flies were attracted to the wine but not to the vinegar or unbaited traps and were most strongly attracted to the combination of wine and vinegar. More flies were captured in traps baited with the combination of ethanol and acetic acid, the most abundant volatiles of wine and vinegar respectively, than in traps baited with either chemical alone or in unbaited traps. A subsequent test found that traps baited with wine plus acetic acid were as attractive as traps baited with wine plus vinegar. In this test, there was no difference in capture in unbaited traps or traps baited with ethanol plus acetic acid, and intermediate capture was obtained in traps baited with vinegar plus ethanol. These findings suggest that it may be possible to develop a synthetic chemical lure for Z. indianus that is based on volatiles from wine used in combination with acetic acid alone or in combination with other volatiles from vinegar.
