| Abstract:
In the Federal Republic of Germany strawberry yellow edge and strawberry crinkle were first observed in 1974. Since then, only strawberry yellow edge has spread. Biological data collected on the strawberry aphid in laboratory experiments indicates, that the natural spread of the strawberry crinkle virus is affected by the life span of the strawberry aphid. The number of aphids which live long enough to complete the latent period of the virus in the vector may be not sufficient for a fast spread of the disease. | |
