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 under these conditions no chemical control against the aphid is necessary for the apple varieties Gala and Fuji. |

An intense search for new cultivars amongat recently collected and introduced ecotypes from Africa is in effect since 1988, at the National Beef Cattle Research Center, of the Brazilian Agricultural Research Corporation (Embrapa Beef Cattle). After agronomic evaluation of a large collection, 21 ecotypes were pre selected for multilocational trial was thus to evaluate the persistence and carying capacity of these eight new Brachiaria brizantha ecotypes after two years of grazing. The experimental design was a randomized complete block with nine treatment and two replicates. The experimental area was divided into 18 paddocks of 1000m. The were grazed acording to a deferred flexible system. After two years. it was possible to selected four ecotypes, which were indicated for animal performance trials aiming at releasing at least one of them as a new cultivar in 2002. |
