Abstract
Field collections for parasites of green cloverworm (GCW), Plathypena scabra (F.), larvae during 1979–1981 revealed three species to be prevalent. Rogas nolophanae Ashmead was predominant in 1979 and 1980, whereas Apanteles marginiventris (Cresson) was most numerous during 1981. Winthemia sinuata (Reinhard) was the third most numerous collected, although they accounted for only a very small proportion of the parasites collected. Percent parasitism in 1979 was not calculated because of low GCW larval survivorship in the laboratory. Overall GCW parasitism in 1980 and 1981 was 34.6 and 44.2%, respectively. Concomitant monitoring of the larval fungal pathogen, Nomuraea rileyi Samson, showed that the pathogen was most prevalent in mid-August.
