Studies on the susceptibility of varieties of apple to the feeding of two strains of woolly aphis (Homoptera) and relation to the chemical content of the tissues of the host


, : Studies on the susceptibility of varieties of apple to the feeding of two strains of woolly aphis (Homoptera) and relation to the chemical content of the tissues of the host. Australian Journal of Agricultural Research 26(1): 157-168

Two strains of Eriosoma lanigerum (Hsm.) have been demonstrated in South Australia, the one ('Blackwood strain') able to attack varieties of apple resistant to the other ('Clare strain'). Both strains displayed well defined differences in the case with which they colonise different varieties of apple and different parts of any one variety, including the roots.
