| North Dakota gross returns from HRS wheat, durum wheat, and barley declined in 1999, relative to the expected gross returns, due to adverse weather conditions and low prices. The total gross return reductions in 1999 was estimated to be $361 million, which was divided into $51 million from weather and disease and $329 million from lower-than-average prices. Gross return reductions were largest in Region 1 (Northwest), followed by Regions 3 (Northeast) and 6 (East Central). HRS wheat accounted for the largest income loss, followed by durum and barley. However, total net farm income increased in 1999 relative to 1998, because of government payments and crop insurance. |

| Avaliou-se a suplementação de proteína (12% de proteína bruta (PB) (T1) e 16% de PB (T2)) na temperatura retal (TR), frequências respiratória (FR) e cardíaca (FC), glicose (Gl), albumina (Alb), proteínas totais (PT), triiodotironina (T3) e tiroxina (T4) de 16 ovelhas Santa Inês, 16 Texel e 15 Ile de France. A FR não diferiu no T1 e T2 na Santa Inês e Ile de France, sendo maior na Texel no T2. FR aumentou na primavera, na Texel, seguida da Ile de France e pela Santa Inês e caiu no outono para Santa Inês e Ile de France. FR foi maior à tarde, na Texel, na Ile de France e na Santa Inês. Maior FC na Santa Inês e Texel no T1 e menor na Ile de France. FC na Santa Inês foi superior nas estações do ano, e na primavera maior para todas as raças. Maior Gl, PT, Alb e... |

| Este evento no fue pronosticado y no fue reconocido como "El Niño" hasta que estuvo bien desarrollado, así mismo su evolución y duración no fue anticipada. Se ha desarrollado una considerable investigación estimulada por la ocurrencia de este evento, lo cual pone de manifiesto el incompleto estado de nuestro conocimiento sobre el fenómeno de "El Niño". |

| Abstract The main open-field and greenhouse producer regions of tomato in Panama (Los Santos, Herrera, Veraguas and Chiriquí provinces) were surveyed to determine the occurrence and distribution of Bemisia tabaci and Trialeurodes vaporariorum during the growing seasons of 2017 and 2018. Twenty-two plots were surveyed, and DNA extracts of 112 adult whiteflies were analyzed by multiplex PCR, using a set of specific primers of B. tabaci MEAM1, B. tabaci NW, and T. vaporariorum. DNA extracts corresponding to 57 individual whiteflies (50.9 %) rendered PCR products of expected size with B. tabaci-specific primers (37 belonged to B. tabaci MEAM1 and 20 to B. tabaci NW), whereas the remaining DNA extracts corresponding to 55 individual whiteflies (49.1 %) rendered... |

| ABSTRACT We aimed to determine the response of cidró (Aloysia triphylla) submitted to different water replacement levels in summer and winter, in order to understand and relate the plant physiological performance under adverse weather conditions. The research was developed in a protected environment, in the city of Frederico Westphalen, Rio Grande do Sul State, Brazil. The experimental design was completely randomized, arranged in a 2x4x2 factorial scheme, two seasons of the year (summer and winter), four water availability (50, 75, 100, 125% of ETo) and two faces of leaf (abaxial and adaxial), with four replications. There were evaluated stomatal vapor diffusion resistance (s/cm), transpiration (µg/cm2/s) and leaf temperature (°C), on both faces of the... |
