[22] The effects of these bacteria on A. ludens are not well studied but it has been proposed by M. Aluja that A. ludens regurgitate internal bacteria onto their host and use the bacterial colonies as a protein source. A. ludens has a broad host range and is a major pest, especially of citrus and mango (Mangifera indica) in most parts of its range. Provided assistance to PPQ canine handlers from Newnan, Georgia in training detector dogs for locating Mexican fruit fly larvae in citrus fruit.

In the event of a quarantine, some of the commodities affected include: Guava, cherimoya, passionfruit, coffee, and many other subtropical fruits [5] According to the USDA, A. ludens is the only important member of the Anastrepha genus that is subtropical instead of tropical and thus has a range much further North than most Anastrepha species.

A. suspensa prey on many of the same fruits in the same regions where A. ludens primarily reside as well. They go on to attribute this genetic diversity to natural selection across the wide habitat range of the fly and to pest management practices.
