New records of Anastrepha (Diptera: Tephritidae) from Paraguay.

This work presents new distribution records in Paraguay for 19 fruit fly species of the genus Anastrepha Schiner, including four new records for the country: A. alveatoides Blanchard, A. australis (Blanchard), A.

L. (Solanaceae) Is Not a Host of (Diptera: Tephritidae): Evidence from Multi-Year Field and Laboratory Studies in Colombia.

Scientifically-based, tephritid fly host status determination lies at the heart of strategic regulatory decisions impinging on international fruit trade. Here we conducted intensive field and laboratory studies with peaches as controls, to determine the host status of for the Medfly- , as this fruit is experiencing a consumption boom worldwide. A total of 98,132 Uchuvas (local name), collected in Colombia from the plant or the ground over a three-year period (2016-2018) did not yield a single .

New records of Anastrepha (Diptera: Tephritidae) primarily from Colombia.

New distribution information, primarily from Colombia, is provided for 60 species of Anastrepha, including the first records of 33 species from Colombia: A. acca Norrbom, A. acris Stone, A.

Nuclear ribosomal internal transcribed spacer 1 (ITS1) variation in the Anastrepha fraterculus cryptic species complex (Diptera, Tephritidae) of the Andean region.

The nuclear ribosomal internal transcribed spacer 1 (ITS1) was sequenced for Anastrepha fraterculus (Wiedemann, 1830) originating from 85 collections from the northern and central Andean countries of South America including Argentina (Tucumán), Bolivia, Perú, Ecuador, Colombia, and Venezuela. The ITS1 regions of additional specimens (17 collections) from Central America (México, Guatemala, Costa Rica, and Panamá), Brazil, Caribbean Colombia, and coastal Venezuela were sequenced and together with published sequences (Paraguay) provided context for interpretation. A total of six ITS1 sequence variants were recognized in the Andean region comprising four groups.
