“…That insect vectors vary within species in ability to transmit plant viruses is now well documented with examples existing for aphid vectors of non-persistent, semipersistent and persistent plant viruses and leafhopper vectors of persistent viruses (Storey, 1932;Storey & Ryland, 1955;Stubbs, 1955;Bj6rling & Ossiannilsson, 1958;Rochow, 1963;Sohi & Swenson, 1964;Hinz, 1966;Bath & Chapman, 1967;Tsai et al, 1972;Thottappilly et al, 1972). In addition, forms and stages of aphid j vectors have been shown to vary significantly in efficiency of non-persistent and persistent virus transmission (Anderson, 1951;Swenson, 1962;Ehrhardt & Schmutterer, 1965;Chapman & Bath, 1968;Thottappilly, 1969Thottappilly, , 1971).…”

“…Biotypes EL and WARF have been shown to transmit BYMV with the same relative transmission efficiency as PEMV (Thottappilly et al, 1972). Tsai et al (1972) separated EL and WARF on their ability to transmit PEMV, but no morphological studies were undertaken to distinguish these two biotypes. In our present studies, attempts were made to differentiate EL and WARF morphologically.…”

The EL and WARF biotypes of Acyrthosiphon pisum (Harris), which were originally isolated on the basis of their differential efficiency in transmitting pea enation mosaic virus (PEMV), were studied morphologically, and a key based on observed morphological differences is presented. The two biotypes also were compared as vectors of broad bean severe chlorosis virus (BBSCV). The EL biotype was more efficient than that of WARF in transmitting BBSCV; 1st‐stage nymphs of EL and WARF were more efficient vectors of BBSCV than their counterpart adults. ZUSAMMENFASSUNG ÜBER MORPHOLOGISCHER UNTERSCHIEDE INNERHALB ACYRTHOSIPHON PISUM UND IN DER ÜBERTRAGUNGSFÄHIGKEIT FÜR DAS SCHWERE CHLOROSEVIRUS DER ACKERBOHNE Die EL und WARF Biotypen von Acyrthosiphon pisum, die ursprünglich nach ihrer Übertragungsfähigkeit für das Scharfe Adernmosaik der Erbse (PEMV) isoliert worden waren, wurden morphologisch studiert und ein Bestimmungsschlüssel ausgearbeitet. Die beiden Biotypen wurden auch als Vcktoren des Schweren Chlorosevirus der Ackerbohne (BBSCV) verglichen. Der EL Biotyp war leistungsfähiger in der Ubertragung von BBSCV als der WARF Typ. Erstlarven von EL und WARF waren wirksamere Vektoren von BBSCV als die entsprechenden Adulttiere.
