De verspreiding van virusziekten van de aardappel (Solanum tuberosum L.) door insekten
The object was to study the relation between virus and the transmitting insect, especially the aphids Myzus persicae Sulz., Myzus pseudosolani Theob., Macrosiphum solanifold Ashm., Aphis rhamni Fonsc. and Aphis fabae Scop. The diseases studied were leafroll, common mosaic (virus A), crinckle (virus Y), stipple streak (virus Yc), interveinal mosaic (virus X), aucuba mosaic (virus F) and spindling sprout.The aphids transmitted these viruses, except aucuba mosaic virus. M. persicae was the best transmitter.The development stage of the aphid was of no influence.A specific relation between M. persicae and leafroll virus was found. Only after incubation of the virus in the insect for 2448 h was the aphid able to transmit leafroll virus. After living 10 days on a resistant plant the aphid was still able to infect the potato plant but the virus could not be transmitted from mother insect to offspring.When the virus-bearing aphid cast its skin the leafroll virus was not lost.The virus was transmitted downwards to the tubers in about 4 weeks.The susceptibility of young plants was very high, in contrast to older plants (old- age resistance).
