First report of Phytomyza orobanchia (Diptera: Agromyzidae) from Poland and Chymomyza amoena (Diptera: Drosophilidae) on Phelipanche ramosa (Orobanchaceae)
Keywords:
broomrape fly, branched broomrape, holoparasitic plantAbstract
Field surveys conducted in Poland in Sep and Oct 2017 revealed infestations of the parasitic plant Phelipanche ramosa (L.) Pomel (Orobanchaceae), also known as branched broomrape, by larvae of the monophagous fly Phytomyza orobanchia Kalt. (Diptera: Agromyzidae). A single broomrape plant could be infested by 1 to 10 larvae of P. orobanchia, and 70 to 80% of the broomrape population was infested. This fly is one of the most effective biological control agents of broomrape. Also, a single female of an alien species of drosophilid, Chymomyza amoena (Loew) (Diptera: Drosophilidae), was observed in 1 locality inSandomierz County, near Szewce, Poland.

Los sondeos de campo realizados en Polonia en septiembre y octubre del 2017 revelaron infestaciones de la planta parásita Phelipancheramosa (L.) Pomel (Orobanchaceae), también conocida como la flor azúl, por las larvas de la mosca monofácea Phytomyza orobanchia Kalt. (Diptera: Agromyzidae). Una sola planta de la flor azúl podría estar infestada por 1 a 10 larvas de P. orobanchia y el 70 a 80% de la población de la flor azúl estaba infestada. Esta mosca es uno de los agentes de control biológico más efectivos de la flor azúl.
