Item Uso do caulim no controle do pulgão preto do feijoeiro Aphis craccivora Koch (Hemiptera:Aphididae)(2019-07-16) Maciel, Thiago Nunes; Evangelista Júnior, Walter Santos; http://lattes.cnpq.br/6728342264331935The present work had as objective to evaluate the effect of kaolin on the aphid Aphis craccivora black control Koch of the bean. The experiment was conducted in the experimental area of the academic unit of Serra Talhada, Universidade Federal Rural de Pernambuco in the municipality of Serra Talhada-PE. Evaluated the effect of kaolin on prevention of aphid infestation black and your effect on mortality of aphid in screenhouse nursery. As it was decided to split the methodology experiment in two steps, in both was used the variety of cowpea "Paulistinha", in the first step to evaluate the efficiency of kaolin as preventive agent was conducted in random blocks design where the treatments consisted of weekly sprays (i) kaolin and scatter adhesive, (ii) only scatter adhesive and (iii) witness (water), enough to cover the whole aerial part of plants, in the second stage in order to evaluate the effect of kaolin on the black aphid mortality the experiment was carried out in completely randomized design, being made manually infestation plants 20 days after your emergency and after the establishment of the colony of aphids the treatments consisted of a single spraying with: (i) kaolin and scatter adhesive and (ii) water, and made scores of individuals living and dead every 24 hours until the fifth day after application. The black aphid a. craccivora presented high infestation in the field, all blocks and treatments with greater than 90% infestation, not showing differences between blocks and treatments. The percentage of infestation per week of black aphid bean cowpea plants showed that in every week (1-5) with larger infestations in the first two weeks with decreasing values ranging of 88.21% 93.91%, respectively. The kaolin presented toxic effect on the black bean aphid with mortality of approximately 20% a day after application. It is concluded that the application of the kaolin as preventive agent in the emergence of the black bean aphid showed no significant effects, not showed your effect on the occurrence and population growth of the aphid, the reduction of the infestation occurred in all treatments. On the other hand, the kaolin caused mortality of black aphid, under controlled conditions, on the first day after application, so applications with kaolin, every two days, will promote a black aphid control in Cowpea bean culture.Item Estudo comparativo dos preceitos propostos por duas correntes de pensamento: o caso da economia verde e agroecologia(2019) Silva, Mariany Barbosa da; Silva, Filipe Lima; http://lattes.cnpq.br/0793640526993320In this paper, the discussion involves two streams of thought or conceptions of analysis on sustainable development cataloged from their references to apparently different economic models, but inserted in the same economic system, which present mediate discrepancies between their concepts, namely agroecology and the green economy. From this problem we have as a general objective: Analyze the discrepancies and convergences between the concepts brought by the principles of agroecology and the green economy in the productive processes that involve pluriactivity, multifunctionality and subsistence production of family agriculture. And while specific objectives: 1) Map the discursive structure of the classic concepts of green economy and agroecology; 2) To structure a comparative framework on sustainability before agroecological and green economy projects. The main characteristics of the green economy are the low carbon emission, efficiency in the use of resources and search for social inclusion. Parallel to this is agroecology, a science (and philosophy of life) whose main characteristic is the production of healthy and natural foods. Both the green economy and agroecological production are aimed at practices that lead to sustainable development, which is explained by a better quality of life.Item A importância da agricultura orgânica na composição da renda familiar do produtor do município de Triunfo-PE(2019) Diniz, Ataine Gonçalves; Leão, Éder Lira de Souza; http://lattes.cnpq.br/4434499456331867The constant search of people for a healthier life has put in evidence the organic agriculture that consists of a balanced way of production, which dispenses the use of substances harmful to the human health and the maintenance of the natural ecosystems. This has meant that the interest of farmers in entering this niche market is increasing, especially by those who belong to the class of small family farmers, who are attracted by the possibility of acquiring a better quality of life through of this system of production, which also constitutes a good alternative for income composition. In the light of this, this work sought, through field research, to identify the main characteristics of the producers of Triunfo -PE, in order to obtain data that allowed to draw the profile of the current situation experienced by them in the production and commercialization of their products. Where, through the obtained results, it was possible to verify the relevance that the gains derived from organic activities play in the income composition of the families, occupying the second place in degree of importance with respect to the income of the family nucleus.
