| The aim of this work was to construct life table of Bemisia tabaci (Gen.) A and B (silverleaf whitefly B. argentifolii Bellows and Perring) biotype (Hem.: Aleyrodidae) on two host plants; cotton, (Gossypium hirsutum L.) and rapeseed, (Brassica napus L.). Experiments were conducted in a growth chamber under 24 ± 2ºC, 55±3% RH and 16:8 (L:D) h photoperiod on caged plants of cotton G. hirsutum L. (Varamin 76 variety) and rapeseed B. napus L. (global variety. The intrinsic rate of natural increase (r m), net reproductive rate (R0) and mean generation time (T) for B. tabaci A biotype was 0.1010 females per female per day, 18.4075 females per female and 30.079 day (d) on cotton; 0.1286, 30.6760 and 26.77 d on rapeseed; and for B biotype (B. argentifolii) those... |

| Avaliou-se a degradabilidade in situ, dos grãos de linhaça, canola, colza e milho, caroço de algodão, e dos concentrados casca e farelo de soja, em ovinos. Foram utilizados três animais da raça Santa Inês, fistulados e providos de cânulas ruminais, mantidos em baias individuais, recebendo diariamente capim picado e ração concentrada. Os alimentos foram incubados em ordem decrescente de 72, 48, 24, 18, 6, 3 e 0h. O teor de proteína dos alimentos avaliados foram 34,77; 30,07; 23,70; 10,64; 26,12; 14,65 e 56,90% para canola, colza, linhaça, milho, caroço de algodão, casca de soja e farelo de soja, respectivamente. A canola e a colza apresentaram baixa degradabilidade efetiva para a MS, com valor médio de 33,68%. O grão de linhaça apresentou degradabilidade... |

| Two rapeseed meals (RM1 and RM2), containing glucosinolates at a concentration of 26 and 40 mumol/g, respectively, were incorporated at increasing levels (10, 20, and 30% for RM1 and 30 and 50% for RM2) in diets of juvenile rainbow trout. Disturbances in the thyroid axis appeared after 14 days of feeding (with a dietary incorporation level of 10%). The dietary supplementation with T-3 or iodine induced an increase in plasma T-3 levels, compared to that in fish fed the RM diets, and reduced the deleterious effect of RM on growth. When trout were reared in seawater, there was also a slight increase in thyroid hormone levels. TSH treatment had no effect on the thyroid hormone plasma levels. The incorporation of 30% of RM1, which induced a lower dietary... |

| Genetically modified (GMO) rapeseed (Brassica napus) is not grown commercially in European Union, but several lines have been approved for production and use as food and feed. A case-specific monitoring of herbicide-tolerant rapeseed, events RT73, RF3 and T45 was established by Ministry of Agriculture of Republic of Serbia. The objectives of the present study were to introduce methods for detection of herbicide-tolerant GM oilseed rape, investigate occurrence and monitor the presence of GM rapeseed in seed and the feed products, as well as to develop a protocol for quantification. The study was based on 48 samples, rapeseed (33) and feed (15) products, imported from EU countries (Germany, Belgium, France, Czech Republic, Austria) and from domestic market.... |

| This study aimed to evaluate different crops and plant species planted after soybeans for one year, in terms of their potential to inhibit the occurrence of weed species. The following crops that were planted as second crop after soybeans were evaluated: (1) corn (Zea mays) planted at spacing of 90 cm between rows, intercropped with Brachiaria ruziziensis in the inter-rows; (2) sunflower (Helianthus annuus); (3) crambe (Crambe abyssinica); (4) radish (Raphanus sativus); (5) rapeseed (Brassica napus); and (6) winter fallow - no plantation after soybeans. Phytosociological characterization of weed species was carried out at the pre-planting of soybeans in the following cropping season. Estimations of relative abundance, relative frequence, relative dominance... |

| ABSTRACT: Herbicide application is an effective weed control method for mitigating crop yield loss; however, herbicide overuse can cause toxicity in non-target plants. The present study evaluated the effects of glufosinate at recommended dose for agricultural application (0.45 kg ha-1) and at overuse dose (0.90 kg ha-1) glufosinate application on photosynthetic performance and nitrogen assimilation of the rapeseed varieties D148 and Zhongshuang 11 (ZS11). Both glufosinate concentrations significantly decreased the content of chlorophyll and nitrogenous compounds, except free proline, and the activity of glutamine synthetase and glutamate synthase, and increased the activity of glutamic acid dehydrogenase in both varieties. When the concentration of... |

| In this paper, we conduct an empirical investigation of potential adoption of herbicide-tolerant (HT) genetically modified (GM) rapeseed in France. Our aim is to study ex ante the potential impact of their adoption in France, in terms of adoption level, economic gains, and distribution of these gains between farmers and input suppliers. We use French survey data about current plant protection practices, in order to compute pesticide costs with conventional (i.e., non GM) crops for individual farms. Then, based on results of technical studies about GM variety trials in France, we compute a predicted pesticide cost with the GM variety. Next, we study adoption rates and gains or losses of farmers (adopters and non adopters) and upstream companies (sellers of... |
