Anastrepha striata

Guava fruit fly
Previous scientific names: Dictya cancellaria Fabricius, Trypeta cancellaria Fabricius


Morphological – adult

This species belongs to the striata-group (note that some publications place this species in the serpentina-group).

Features include:

  • frons without brown markings except ocellar tubercle
  • scutum with distinct dark patterns, posteriorly with brown or orange brown band or other transverse marking or larger posteromedial mark, with large U-shaped mark including posterior band and vittae
  • scutellum entirely yellow or with dark markings only on extreme base of disk
  • subscutellum yellow to red brown medially, dark brown laterally
  • wing with typical Anastrepha pattern (S-band complete or at most interrupted at crossvein r-m, C-band and at least proximal arm of V-band present), C-band and S-band connected or separated, V-band proximal arm as dark as apical half of S-band and not connected anteriorly to S-band, V-band distal band usually complete, but can be incomplete or absent
  • abdominal tergites without brown markings
  • aculeus length 1.95 – 2.3 mm; aculeus tip length 0.22 – 0.33 mm; aculeus tip width 0.17 – 0.2 mm
  • lateral aculeus margins not curved dorsally, serrated part 0 – 0.2 times length of tip
  • aculeus tip is distinctly broad and wedge-shaped with a very blunt apex and extremely fine lateral serrations.

Similar species

Anastrepha striata is a smaller species of Anastrepha and best diagnosed by the distinct dark colour markings on the scutum, especially the presence of a U-shaped pattern. It belongs to the striata-group, which contains A. bistrigata with which it may possibly be confused; however, A. bistrigata does not possess the distinct U-shaped patters on the scutum.

Pest Status

  • Exotic
  • Important pest in the American tropics and subtropics, especially of guavas and other myrtaceous fruits
  • Also recorded as attacking mango, mombins, orange, and peach


No known record, but can be captured in traps emitting ammonia.
