Utetes lectoides (Gahan, 1930)

For additional information, see the Utetes page.
Taxonomic History / Nomenclature
Though treated as a synonym of Opius canaliculatus by Wharton and Marsh (1978), this western species seems to have a slightly shorter ovipositor and thus was recognized by Wharton (1997) as distinct.

This species was originally described as Opius lectoides by Gahan (1930). It was later formally transferred from Opius to Utetes by Wharton (1997). Utetes had been recognized as a subgenus of Opius by Fischer (1972) , and later elevated to generic rank by Wharton (1988). However, most of the species that attack Tephritidae were not formally transferred to Utetes until 1997, after Utetes had been redefined (Wharton 1997).

Utetes lectoides was originally described from reared material collected in Oregon Gahan (1930). Records from eastern U.S. and Canada need verification.

Label data for specimens in the Texas A&M University Collection, determined by R. Wharton in 1983, are as follows:

Biology / Hosts
The material from which this species was originally described was reared from Rhagoletis zephyria Snow infesting fruits of snowberry, Symphoricarpos. It was subsequently reared from apple maggot, Rhagoletis pomonella, after the apple maggot was discovered in northwestern USA (AliNiazee 1985).
Biological Control
See AliNiazee and Brunner (1986) for suggestions for possible use in management of apple maggot in Oregon.
