Bactrocera oleae

Definition

A tephritid fruit fly (Diptera: Tephritidae) whose larvae develop exclusively in olive fruits, causing direct damage through feeding tunnels and secondary microbial rot. Native to the Mediterranean basin and now invasive in California and other olive-growing regions, it is the most economically significant pest of cultivated olives worldwide.

Etymology

Bactrocera from Greek baktros (staff, cudgel) + keras (horn), referring to the club-shaped wing pattern; oleae from Latin olea (olive), denoting the host association.

Example

In integrated pest management programs for Bactrocera oleae, mass trapping with food-based lures and targeted spinosad bait sprays are combined to reduce larval infestation rates below the economic threshold of 10% fruit damage.

Synonyms

• Olive fruit fly
• olive fly

Related Terms

• Tephritidae
• Dacinae
• Phytophagy
• fruit fly
• Integrated Pest Management
• olive cultivation
• host specificity

Usage Notes

Sometimes confused with the smaller, non-pest olive fly Sphaeniscus atilius (Ulidiidae), which breeds in decaying olives rather than intact fruit. The specific epithet is occasionally misspelled 'olea' in older literature. Rossi, 1790 is the accepted authority, though Gmelin, 1790 appears in some databases due to historical synonymy.
