“…The species transmits at least the following viruses: OSDV, EWSMV, Aster yellows virus and maize rough dwarf virus (e.g. SLYKHUIS 1958, SLYKHUIS and WATSON 1958, PRIJ §A 1958, VACKE and PRI'AA 1959, KLINKOWSICI 1961, BLATTNY et al 1965, HARPAZ et al 1965. The reduction of grain yield caused by the toxic saliva are apparently quite small in ali countries, while those resulting from the viruses, especially OSDV, may be very large.…”

“…The plants exhibited a wide range of symptoms, varying from a few lesions to numerous rings on all the leaves except a few lower ones, and often on the husks and sheats as well. BLATTNY et al (1965) observed and illustrated leaf fleck in Czechoslovakia. Symptom expression was favoured by hot, sunny weather.…”

“…Tosic (1962) described four of the virus diseases of maize in Serbia, including leaf fleck, and stated that in the regions, where hybrid corn was grown, 50-90 % of the plants were infected with virus diseases, while in regions where dent and flint corn were grown virus infections were observed to the extent of 15-30 %. BLATTNY et al (1965) observed and illustrated leaf fleck in Czechoslovakia. This is all the information which we had on maize leaf fleck before the author published his first paper on this disease (1965).…”

“…The second type of syndrome is noticeably milder, infected plants being almost as tall as non-infected ones, and the number of vein swellings much smaller. This non-dwarfing form of the disease also affects the reproductive organs of the plant resulting in either partial sterility of both male and female flowers, or other floral malformations as described by Grancini (1958), Harpaz (1959) and Blattny. Pozdena & Prochazkova (1965).…”

The planthopper‐borne rough dwarf virus disease manifests itself on maize plants in two different groups of symptoms presumably caused by two distinct strains of the virus. The severe, dwarfing strain is transmitted to maize plants only by Laodelphax striatellus and Javesella pellucida. The milder, non‐dwarfing strain is transmissible by two additional delphacid species, namely Delphacodes propinqua and Sogatella vibix, which are unable to provoke the dwarfing‐strain syndrome on maize test plants. However, when the dwarfing strain was injected into the haemocoel of these two non‐vectors, the virus, upon replication and circulation in this unnatural medium, was modified into a novel strain inducing hermaphroditism in the vector‐inoculated maize test plant. Modification of the dwarfing strain into the non‐dwarfing one also occurs in the body of the natural vector (L. striatellus) when the insect acquires the former strain in an imperfect manner. This happens when the vector feeds on infected maize which is an unsuitable host species for this planthopper, or when the virus is acquired by trans‐ovum transmission. All above‐mentioned modifications are irreversible. ZUSAMMENFASSUNG VEKTOR‐BEDINGTE MODIFIKATIONEN IN EINEM PFLANZENVIRUS Die durch Langkopfzirpen übertragene Rauhverzwergungsvirose zeigt sich auf Maispflanzen in zwei verschiedenen Symptomgruppen, die vermutlich durch zwei getrennte Virusstämme verursacht werden. Der schwere, Verzwergung erregende Stamm wird auf die Maispflanzen nur durch Laodelphax striatellus und Javesella pellucida übertragen. Der mildere, nicht Verzwergung erregende Stamm ist auch durch zwei andere Langkopfzirpenarten (Delphacodes propinqua und Sogatella vibix) übertragbar, die aber unfähig sind, das Verzwergungssyndrom an Maistestpflanzen hervorzurufen. Jedoch, wenn der Verzwergungsstamm in das Haemocoel dieser zwei Nichtüberträger injiziert wurde, modifizierte das Virus infolge der Vermehrung und Zirkulation in diesem unnatürlichen Medium der Zirpenkörper in einen neuen Stamm. Dieser neue, vorher nicht vorhandene Stamm führte Hermaphroditismus in die vektor‐geimpfte Maistestpflanze ein. Modifikation des Verzwergungsstammes in einen nicht Verzwergung erregenden Stamm kommt auch im Körper des natürlichen Vektors (L. striatellus) vor, wenn dieser Überträger den erstgenannten Stamm auf unvollkommene Weise aufnimmt. Dies geschieht, wenn der Vektor auf infiziertem Mais saugt, der eine ungeeignete Wirtsart für diese Zirpe ist, oder wenn das Virus durch eine transovum‐Übertragung von der Mutterzirpe auf ihre Nachkommen aufgenommen wurde. All diese genannten Modifikationen sind nicht umkehrbar.
