Abstract

The transmission of the carrot mosaic virus (CMV) by the aphidsAcyrtJiosiphon pisum HARRÍS,Cavariela aegopodii SCOP, andMyzus persicae SULZ was proved experimentally. It was observed simultaneously that CMV has a non-persistent character. CMV can be transmitted already 2 min after acquisition feeding by the aphidsMyzus persicae SDLZ andCavariella aego-podii Scop. When the time of acquisition feeding is prolonged to 4 min, CMV is transmitted also by aphidAcyrthosiphon pisum HAREÍs. The host range of the investigated virus wasalso determined and its transmission to 8 plant species, belonging to 4 families, was achieved. On the basis of studies of the vector virus relationship and of the host range, further proof was given for the different character of the Australian Carrot motley dwarf virus, theApivm virus 1 Roland and CMV. The experiments showed that preliminary starving of the aphids for 1 h increases their ability to transmit the virus by 3–3%.

Abstract

Experimementálně byl prokázán přenos viru mozaiky mrkve (VMM) mšicemi, a to mšicí:Acyrthosiphon pisum HARRÍS,Cavariella aegopodii SCOP. aMyzus persicae SULZ. Zároveň bylo zjištěno, že VMM má neperzistentní povahu. VMM je přenosný již po 2 min. nabývacího sání mšicemiMyzus persicae SULZ aCavariella aegopodii SCOP., při prodlouzení doby nabyvacího sání na 4 min. je VMM přenášen i mšicíAcyrthosiphon pisum HARRIS. U studovaného viru byl dále vyšetřován jeho hostitelský okruh a podařilo so ho píenést na 9 druhů rostlin, pocházejících ze 4 čeledí. Na základě studia vztahu vektor—virus a hostitelského okruhu byl podán další důkaz odlišení VMM od viru australské zakrslosti mrkve (Carrot motley dwarf virus) a od viru mozaiky celeru (Apium virus 1 ROLAND). Při pokusech bylo zjištěno, že předbězné hladovění mšic po dobu 1 hod. zvyšuje jejich schopnost přenést virus o 3,3 %.

Abstract

Экспериментальным путем доказан перенос вируса мозаики моркови (BMM) тлями, а именно тлями:Acyrthosiphon pisum HARIS,Cavariella aegopodii SCOP.,Myzus persicae Sulz. Установлено также, что BMM неперсистентной природы. BMM переносима уже после 2-минутного сосания тлямиMyzus persicae SULZ иCavariella aegopodii SCOP., в случае удлинения врвмени сосания на 4 мин. BMM переносима и тлейAcyrthosiphon pisum HARIS. У изучаемого вируса исследован также округ его рас.тений — хозяев и удалось его перенести на 9 растений из 4 семейств. На основании изучения отношений вектор — вирус и окоуга растений — хозяев принесено дальнейшее доказательство для отличения BMM от вируса австралийской карликовости моркови (Carrot motley dwarf virus) и от вируса мозаики сельдерси (Apium вирус 1 ROLAND). В опытах установлено, что предварительное голодание тлей в тейение 1 часа повышает их способность переносить вирус на 3,3%.
