Trapping systems for Zaprionus indianus (Diptera: Drosophilidae)

An African fig fly (AFF), Zaprionus indianus Gupta (Diptera: Drosophilidae), is an invasive fruit pest that has spread rapidly through much of the eastern United States after first being detected in Florida in 2005. This drosophilid is a primary pest of figs in Brazil, so there were initial concerns that it would be a primary pest of small fruit in the US.  Although it has a wide host range in Africa, it has been found primarily in damaged fruit in Florida to date. With the appearance of the spotted wing drosophila (SWD), Drosophila suzukii (Matsumura), there is a greater interest in pest drosophilid trapping systems and the development of a trapping system to monitor distribution of AFF. Studies were conducted in south Florida to evaluate vinegar-based baits as attractants for this fly.  Baits included apple cider vinegar, combinations of rice vinegar and wine, and chemicals emitted from those baits.
