Figure 12.  Mexican fruit flies, Anastrepha ludens (Loew), laying eggs in grapefruit during a laboratory test. The Mexican fruit fly is a very serious pest of various fruits, particularly citrus and mango, in Mexico and Central America. Its natural distribution includes the Rio Grande Valley of Texas, where populations routinely attain pest status if control measures are not practiced. It is a frequent invader in southern California and Arizona. Mexican fruit fly represents a particular threat to Florida because of its special affinity for grapefruit, of which Florida is one of the world’s leading producers. Mexican fruit fly larvae are transported widely in infested fruits. This 6-page fact sheet was written by H. V. Weems, Jr, J. B. Heppner, G. J. Steck, T. R. Fasulo and J. L.
