On the Identity of the common Dipterous Parasite of the Larva of Diatraea saccharalis, Fabr., in the Northern Provinces of Argentina

Abstract

The first reference to the existence in Argentina of the parasite that is the subject of the present article appears to be that of Messrs. Rosenfeld & Barber, who, for lack of a more exact determination, referred to it as “ el parásito díptero ” or “ el díptero.” Some time after the appearance of their publication, these entomologists sent specimens to the late Dr. Frederick Knab, who determined them as Sarcophaga ochropyga, van der Wulp ; these specimens had been reared from Diatraea saccharalis, Fabr. (sugar-cane moth borer) at the Tucumán Agricultural Experiment Station, and were later incorporated in the collection of that institution under the “ accession number 47,” and bore labels indicating Dr. Knab's identification.
