Host Range

Pumpkin (Cucurbita pepo)(Cucurbitaceae) is the only recorded host (Leblanc et al. 2012).

Major commercial hosts (Drew 1989):

  • Cucurbita pepo (pumpkin)


Papua New Guinea (New Britain) (Drew 1989).

Similar species

Distinctive in having a medial vitta and recurved pattern on the wings.

Additional information:

Zeugodacus decipiens larvae can co-exist in pumpkin with melon fly larvae (Zeugodacus cucurbitae) but its rate of development is much slower.

Previously known as Bactrocera (Paradacus) decipiens in the Zeugodacus subgenus group until Zeugodacus was elevated to genus level by Virgilio et al. 2015. Now known as Zeugodacus (Paradacus) decipiens. For a full list of Zeugodacus species see DeMeyer et al. 2015.
