Conura albifrons

(Walsh, 1861)

Conura albifrons is a native North American hyperparasitoid in the Chalcididae. It has been documented attacking Diadromus pulchellus, an ichneumonid introduced for of the leek moth (Acrolepiopsis assectella). This hyperparasitoid relationship represents a potential challenge to biological control programs, as native hyperparasitoids can reduce the effectiveness of introduced natural enemies. The is recorded from multiple Canadian provinces including Alberta, British Columbia, Manitoba, and New Brunswick.

Identification

As a member of Chalcididae, Conura albifrons likely exhibits the 's characteristic enlarged hind with serrated inner margins and a distinct pronotal carina. The specific epithet 'albifrons' (white-fronted) suggests a pale or white-marked , which may serve as a distinguishing feature from . Positive identification requires examination of morphological characters used in chalcidid , including antennal structure, wing venation patterns, and body sculpturing.

Distribution

Recorded from Canada: Alberta, British Columbia, Manitoba, and New Brunswick. The is native to North America.

Diet

Hyperparasitoid: attacks the ichneumonid Diadromus pulchellus.

Host Associations

Behavior

Exhibits hyperparasitoid , attacking an established agent. This represents a case of native hyperparasitoid interference with introduced .

Ecological Role

Native hyperparasitoid with potential negative impact on programs. By attacking introduced agents, it may reduce their effectiveness in managing pest .

Human Relevance

Documented as a factor potentially compromising efforts against the leek moth, an agricultural pest. Its presence highlights the importance of considering native hyperparasitoid when evaluating the success of introductions.
