摘要：

Two indigenous species of Trichogramma were reared from natural populations of the blackheaded fireworm, Rhopobota naevana (Hubner) infesting cranberries in British Columbia, Canada. One was identified as Trichogramma sp. nr. sibericum Sorokina and the other was Trichogramma minutum Riley. Percentage of parasitized hosts increased during the season in an abandoned field, but decreased in a commercial field where pesticides were used. The potential of Trichogramma as a biological control agent against the fireworm is discussed.
