Fruit flies (Diptera: Tephritidae) from the geeach Annona species at each locality. In all, 23.1 nus Anastrepha are endemic to subtropical and kg of A. liebmanniana fruits were collected (15 tropical areas in the Americas (Stone 1942; Aluja kg in Feb 2010 and 8.1 kg in Feb 2012); 3.2 kg of 1994), and collectively infest a wide variety of A. reticulata fruits were collected in Apr 2010; economically important hosts (Hernandez-Ortiz and 1.6 kg of A. cherimola x A. reticulata fruits 1992; Norrbom 2004). In Mexico and northern were sampled in Oct 2010. Collections focused Central America, Anastrepha ludens Loew, the on fruit that appeared to be physiologically ma Mexican fruit fly, is the most common and most ture. After sampling, all fruit was labeled and damaging insect pest of perennial fruit crops such transported to the laboratory. The collected as citrus (Rutaceae) and mango (Anacardiaceae). fruit were placed in individual trays labeled This polyphagous species also attacks fruit spewith the name of the host species and covered cies belonging to the plant families Myrtaceae, with mesh netting to prevent the emerging in Fabaceae, Rosaceae, and Sapotaceae, among othsects from escaping (Borror & White 1970; Pena ers (Baker et al. 1944; Bush 1962; Aluja & Maret al 2002). Pupae were collected and kept in tinez 1984; Aluja et al 1987; Aluja 1993,1994). plastic containers with moist (50-70%) vermic Several species of Anastrepha have been reulite until the emergence of the adult insects, ported to infest Annona spp. For example, in Emerged fruit flies were collected and placed Mexico several authors have reported A. ludens in vials containing 70% alcohol. Keys provided feeding in Annona cherimola Mill., A. reticulata by Hernandez-Ortiz (1992) were used for insect L., A. squamosa L., and A. muricata L. (Baker et taxonomic identification. Voucher specimens al 1944; Aluja et al 1987; Hernandez-Ortiz 1992; of A. ludens were deposited at the Instituto de White & Elson-Harris 1992; Vidal 1994). In the Investigaciones Forestales, Universidad Vera state of Veracruz, Piedra-Rodriguez & Zunigacruzana, in Xalapa, Veracruz, Mexico. Voucher Anell (1993) reportedA. ludens infestingA. cherispecimens of A. liebmanniana and A. cherimola mola fruits in the locality of Llano Grande, Mux A. reticulata were deposited in the herbarium nicipality of Teocelo. Here, we provide the first XALU of Faculty of Biology of Universidad Ve report of A. ludens feeding in two new host plants: racruzana (Xalapa, Mexico). Annona liebmanniana BaiW.

This is the first firm previous reports indicating that A. ludens report documenting the emergence of A. ludens infests fruits of A. reticulata. from A. liebmanniana (Tuzantan, Chiapas) and Fruits were collected in 2010 and 2012 in difA. cherimola x A. reticulata (Llano Grande-Vera ferent agro-ecosystems in the communities of cruz).
