Apontamentos críticos para o tratamento da questão ambiental na perspectiva da emancipação

The belief in the existence of an ecological crisis that would affect the future of the planet, is one of the factors that causes the appearance of ecological concern, resulting in the adoption of non-predatory consumer practices and more respectful relationships with non-humans beings. This study starts from the assumption of the existence of an environmental question, and aims to investigate some of the cultural causes of human predation and identify possible ways in which environmental question can be treated critically to search overcomes. Follows the reasoning that western society as a complex of social relations, the capitalism, as a mode of production utilities and rational right, are all consequences of the modern rationality, cognitive and moral logic that transforms people and nature in satisfaction instruments of individual interests. However, despite being identified as the causative root of environmental question, modern rationality takes with it enough to promote the development of ecological respect, necessary in confronting and overcoming the environmental question, as it will be applied as a principle in redefinition of the relationship of human beings with themselves and with nature. And modern rationality can also make capitalism more efficient in the use and reuse of materials so as to consume fewer resources on the planet to satisfy human needs.

Technical and economic evaluation of different types of control of Brevipalpus phoenicis (Acari: Tenuipalpidae) in citrus leprosies management

The objective of this work was to evaluate the effect of acaricide applications and pruning of symptomatic branches in citrus leprosis management in Brazil. It was conducted in an orange plantation of the 'Pera' variety, grafted onto the 'Cleopatra' tangerine, in two seasons (2006-2007 and 2007-2008). The experimental design was randomized blocks in a factorial scheme consisting of the following factors: (A) acaricide, in three levels: spirodiclofen and cyhexatin applied in rotation, lime sulphur; no acaricides; (B) pruning to remove branches that showed symptoms of leprosis, with two levels: with pruning, without pruning. We carried out periodic assessments of Brevipalpus phoenicis (Geijskes) populations (vector of the leprosis virus), leprosis incidence and severity, fruit yield, and the economic feasibility of the applied strategies. Based on the results, we concluded that spirodiclofen and cyhexatin were more effective than lime sulphur in B. phoenicis control. Control with lime sulphur required more applications than spirodiclofen and cyhexatin in rotation, making it more expensive. Pruning of symptomatic branches used in isolation was not sufficiently effective to control leprosis and significantly increased control costs. Profits were higher when the control involved sprayings of spirodiclofen and cyhexatin in alternation, with or without pruning.

Um mundo radicalmente melhor: criatividade, colaboração e padrão de redes como estratégias para o desenvolvimento sustentável

There are substantial evidences that the period experienced by humanity globally is unprecedented and is heading towards a major transformation that results from the Globalization. Totally conditioned to the addictions of the dominant and predatory capitalism, humanity has, for decades, exhausted natural resources, disregarded the nature of its own social existence and walked away from its humanity. It is notable, however, an impressive flow of factors that dialogue and support each other as trends that go towards sustainable development, based on the harmonious integration between Technology, Culture, Society, Environment and Economy. This emerging moment can be seen from the perspectives of the Creative Economy as economic paradigm centered on the subjectivity and the human capacity to undertake innovative services, products and solutions guided by social values. Within this fluid and dynamic global context, initiatives that legitimately intend to act sustainably are gaining space. This socioeconomic moment fosters and is fostered by new kinds of work and organization guided by the Collaboration and social structuring on Network Patterns. These new social models significantly transform the understanding and insights about the Communication flows. The HUB São Paulo, as creative and social organization that operates under the logic of Collaboration through a Network Structure, was the subject of a case study used to sustain the defense of this emerging scenario and also to perform an analysis on the new role of Communication, at perspectives of transformation of mental paradigms towards sustainability and establishment of meaningful connections

Platinosomíase em felinos domésticos: um diferencial para obstrução biliar

The platinosomiase is a disease the hepatobiliary system of domestic felines being caused by trematode Platynosomum fastosum. The life cycle of the parasite includes the presence of three intermediate hosts (snails, terrestrial isopodes, lizards or frogs). The cat is considered definitive host of the parasite and acquires the infection eating a vertebrate intermediate host containing metacercariae. The adult parasites generally inhabit the liver, gallbladder and bile ducts of cats. The severity of clinical manifestations depends mainly on the number of flukes in the biliary tract. Many animals are asymptomatic or exhibit nonspecific clinical manifestations such as anorexia, lethargy, weight loss, vomiting and diarrhea. In large infestations can occur biliary obstruction resulting in jaundice, cirrhosis, hepatitis cholangiohepatitis and even death. The definitive diagnosis is accomplished through by the detection of fluke eggs in feces or through laparotomy and liver biopsy. Treatment should be based on the use of anthelmintic for the elimination of the parasite and supportive therapy for the animal. Prevention is difficult due to predatory nature of the cat. The control can be accomplished through periodic fecal examinations

Efeito Pesticida de Ésteres de Sacarose Sobre Calacarus heveae Feres (Acari: Eriophyidae) em Dois Clones de Seringueira

Sucrose esters are biodegradable, non pollutant and safe for health; moreover, they have shown great potential in the pest control. We tested a crude mix of sucrose esters on the survivorship and oviposition of Calacarus heveae Feres (Acari: Eriophyidae) females, an important rubber tree pest mite. The females were collected from rubber leaflets of the GT 1 and RRIM 600 clones. The mites were kept on stock arenas placed in rearing chamber at 28 + 0,1°C, 80 + 10% of relative humidity and 12h of light phase about two weeks before the assays. After this period, the mites were transferred to assay arenas made with leaflets from the same clone of stock arenas. The survivorship of females sprayed with sucrose esters in the concentrations of 1, 2, 3 and 4 g/L and their oviposition effect with 0.5 and 1 g/L were analyzed. The mites sprayed with 4 g/L had about 80% of mortality, while those with 1 g/L around 60%. All mites that died in the treatments with sucrose ester became dark with wrinkled tegument and decreased their body volume, suggesting dehydration. We also observed the efficacy of 1 g/L concentration to decrease the female oviposition in about 50%, in the third day after spraying. No differences were observed in the mortality and oviposition between females kept on both clones.

Mites (Arthropoda: Acari) associated with three species of the genus Jatropha (Euphorbiaceae) in Brazil, with emphasis on Jatropha curcas L.

The physic nut (Jatropha curcas L.) (Euphorbiaceae) has emerged as a new option in cultivation aimed at biodiesel production. In order to provide information that may be useful to further develop management plans for that specific crop, samples of mites were collected from cultured and wild J. curcas plants in various regions of the country and from two other species of the same genus, Jatropha gossypiifolia L. and Jatropha mollissima (Pohl) Baill. in the northeastern region of Brazil. Altogether 31 species belonging to 10 families were recorded. The family Phytoseiidae presented the largest number of species (17). Polyphagotarsonemus latus Banks (Tarsonemidae) was the most abundant species (8,503 specimens). A dichotomous key was prepared to identify all the sampled species. At least four mite species of the samples deserve attention as showing potential for being pests in the crops of J. curcas, Brevipalpus phoenicis, Brevipalpus obovatus, Polyphagotarsonemus latus and Tetranychus bastosi, the latter two often found in great abundance.

Phytoseiidae mites associated with Hevea spp. from the Amazon region: a hidden diversity under the canopy of native trees

Despite the Amazon Forest being the largest tropical forest in the world, and cradle of rubber trees (Hevea brasiliensis), no studies have aimed to report the occurrence of mites associated with native trees from this ecosystem. Our survey investigates the phytoseiid mites associated with five species of native rubber trees from nine sites of the Amazon Forest, and also presents a major review of phytoseiid species from natural vegetation in Brazil. We found a total of 1305 mites, belonging to 30 species, of which seven were new to science, Amblydromalus akiri sp. nov., Amblyseius chicomendesi sp. nov., Amblyseius duckei sp. nov., Amblyseius manauara sp. nov., Iphiseiodes katukina sp. nov., Iphiseiodes raucuara sp. nov. and Typhlodromips igapo sp. nov.; beyond two new records for Brazil, Iphiseiodes kamahorae and Amblyseius martus. Our results emphasize the importance of Amazon native trees as an unexplored source of predator mites, which in turn may be further studied as biological control agents of pest mites on rubber trees. The impressive diversity, endemism and rate of new species found highlight the importance of studies on arthropod communities associated with the Amazon vegetation.
