Última Identification of the Er1 resistence gene and RNase S-alleles in Malus prunifolia var. ringo rootstock Scientia Agricola Agapito-Tenfen,Sarah Zanon; Dantas,Adriana Cibele de Mesquita; Denardi,Frederico; Nodari,Rubens Onofre. Woolly apple aphid (WAA; Eriosoma lanigerum Hausm.) is a major insect pest that has significant economic impact on apple growers worldwide. Modern breeding technologies rely on several molecular tools to help breeders select genetic determinants for traits of interest. Consequently, there is a need for specific markers linked to the genes of interest. Apple scions and rootstocks have an additional barrier to the introduction of pest resistance genes due to the presence of self-incompatibility S-RNase alleles. The genetic characterization and early identification of these alleles can amplify the contribution of a breeding program to the selection of resistant genitors that are as compatible as possible. In this study, we identified the Er1 gene involved in...

Bras. Frutic. Monteiro,Lino Bittencourt; Souza,Alexander; Belli,Edson Luiz. The parasitism of the woolly apple aphid (Eriosoma lanigerum Hausmann) by Aphelinus mali (Hald.) was evaluated in apple orchards cultivated with the varieties Gala and Fuji in Fraiburgo County, State of Santa Catarina, Southern Brazil. Colonies of the woolly apple aphid were evaluated during one year on 16 apple trees of each variety, starting in August 1999. The number of aphids at the mummy stage or presenting the orifice of the parasitoid emergence was recorded. Results have shown that A. mali parasitized more than 50% of the woolly apple aphids and occurred during the four seasons. It was concluded that that under these conditions no chemical control against the aphid is necessary for the apple varieties Gala and Fuji.
