ABSTRACT. The South American Tortricid Moth (Meyrick, 1909) (Lepidoptera: Tortricidae) is often found damaging vineyards and other temperate fruit orchards, in Southern Brazil and Uruguay. This work was conducted to study the seasonal occurrence of A. sphaleropa adults in vineyards using sexual synthetic pheromone. Based on weekly evaluation of A.

ABSTRACT. Plants were propagated by fruits and cuttings. Cuttings were rooted in two seasons:autumn (May 19, 1992), in a field nursery under plastic cover, and spring (September 14, 1992) in plastic containers under shade. Seeds were sown in a field nursery under plastic cover on June 8, 1992. Plants were taken to the field on November 25, 1992, planted at a spacing of 30 x 40 cm. For the three treatments, the mortality of plants after transplanting was 42, 4 and 46% respectively. Within each treatment, plants were harvested on February 5, 1993, November 12, 1993 and November 3, 1994.

ABSTRACT. The claim that organic agriculture produces higher levels of phytochemicals has been controversial for decades. Using strawberries as a model crop in field conditions, a preharvest leaf wounding stress was applied to study the production of phytochemicals in fruits. As a result phenolic compounds (PCs) and total soluble sugars increased significantly, where specific phenylpropanoids showed increment up to 137% and several genes related to PCs biosynthesis and sugar transport were overexpressed.

RESUMEN. En este trabajo se evaluaron accesiones de frutos nativos de ?Arazá? (Psidium ­cattleianum), ?Guaviyú? (Myrcianthes pungens) y Guayabo del país? (Acca sellowiana) como parte de un programa de selección de variedades para obtener cultivares comerciales. El objetivo es ofrecer a los productores nuevas posibilidades de cultivos frutícolas locales y brindar a los consumidores alternativas alimenticias con reconocidas propiedades nutricionales y nutracéuticas.

ABSTRACT. We examined the effect of lipid content in the diet on the transcriptome of the Longissimus dorsi muscle in pigs. Our objective was to examine changes at the molecular level affecting economically relevant meat quality characteristics such as intramuscular fat deposition and fatty acid profile. The treatments consisted of isoproteic and isoenergetic diets with differing lipid contents due to addition of rice bran. The control diet (T0) was a normal basic diet and the test diet (T15) had 15% rice bran.

RESUMEN. Las frutas y hortalizas pueden contener contaminantes que llegan al producto en cualquier punto de la cadena productiva.

ABSTRACT. We have investigated the origin of swine breeds through the joint analysis of mitochondrial, microsatellite, and Y-chromosome polymorphisms in a sample of pigs and wild boars with a worldwide distribution. Genetic differentiation between pigs and wild boars was remarkably weak, likely as a consequence of a sustained gene flow between both populations.

ABSTRACT. The incidence of short oestrous cycles and kidding rate in dairy goats were evaluated after administering a low dose (500 IU) of equine chorionic gonadotrophin (eCG) during two breeding seasons. The first year, 46 does (Saanen, n = 10; Nubian, n = 26; and their local crossbred, n = 10) were used. The second year of the study was performed on 34 of the same does (Saanen, n = 4; Nubian, n = 19; local crossbred, n = 11). The goats were synchronised with intravaginal sponges that contained medroxyprogesterone acetate during a period of 14 days.
