The concept of environment involves social, political and economic aspects, in addition to natural elements. The acknowledgement that the environmental issue is complex highlights the importance of understanding the dynamics of relations that guide the individuals in their interactions with the environment. In this sense, studies have shown the relation between values, beliefs and behaviors. The theory on values developed by Schwartz (1992) identifies the complexity of the relations between values and behavior, organizing the field of human motivation into ten motivational types. Studies conducted by Pato (2004) on environmental beliefs are capable of indicating how the individuals relate to the environment, and its predisposition in acting or not in an ecological manner, allowing an understanding of ecological behavior and its forms of manifestation. Therefore, the objective of this study consisted of analyzing the value perception over environmental beliefs and ecological behavior of the individuals inserted into the environmental theme of the municipality of Lavras, Minas Gerais, Brazil. The research was conducted using a sample of 82 participants, comprised in its majority of male (62.2%), married (54.9%) individuals, and those with age from 31 to 40 years (35.4%). A survey of four segments was conducted: Ecological Behavior Scale (EBS), Environmental Beliefs Scale (EBeS), Schwatz Value Profile (SVP-40) and sociodemographic variables. The participants assumed, first, a value orientation directed to the universalism motivational type, which involves an important set of values for understanding the behaviors in relation to the environment. Furthermore, the results showed that the behaviors related to urban cleaning and economy of water and energy are more easily assimilated, while behaviors oriented to activism/consumerism and recycling were not yet incorporated in a satisfactory manner. On the other hand, the fact of belonging to an institution of which mission is to care for the environment seems to induce the participants to show a greater predisposition to pro-environmental behaviors. The environmental issue, urgent and moved by not always confluent debates, points to the need for reorganizing daily life, which necessarily involves change in values and behaviors. Thus, this study is relevant given that the interaction between the constructs can contribute with the research and the proposition of strategies that promote a reduction of behaviors damaging to the environment, as well as the strengthening of those that contribute for its preservation, sensitizing the actors involved to reorder their roles for benefiting the environment.

Bacterial fruit blotch of cucurbits (BFB), caused by the seed borne Gramnegative bacterium Acidovorax citrulli is a serious threat to cucurbit industry worldwide. Since late 1980`s after devastating outbreaks in watermelon fields in southern United States, BFB has spread worldwide and has been reported in other cucurbit crops such as melon, pumpkin, cucumber and squash. To date, there is evidence for the existence of at least two genetically and pathogenically distinct populations of A. citrulli. In Brazil, the first report of BFB was in 1991, in a watermelon field in São Paulo. Although widespread in the country, BFB has been a major problem to melon production. More precisely, BFB has caused significant yield losses to melon production in northeastern Brazil, which concentrates > 90% of the country`s melon production. Despite the management efforts and the recent advances in A. citrulli research, BFB is still a continuous threat to the cucurbit industry, including seed producers, growers and transplant nurseries. To better understand the population structure of A. citrulli strains in Brazil, and to provide a basis for the integrated management of BFB, we used pulsed-field gel electrophoresis (PFGE), multilocus sequence analysis (MLSA) of housekeeping and virulence-associated genes and pathogenicity tests on different cucurbit seedlings to characterize a Brazilian population of A. citrulli strains from different hosts and regions. Additionally, we conducted for the first time a comparative analysis of the A. citrulli group I and II population at genomic level and showed that these two groups differ on their genome sizes due to the presence of eight DNA segments, which are present in group II and absent in group I genomes. We also provide the first evidence to suggest that temperature might be a driver in the ecological adaptation of A. citrulli populations under nutrient-rich or -depleted conditions. Finally, in order to improve the routine detection of A. citrulli on melon seedlots, we designed a new primer set that is able to detect the different Brazilian haplotypes, thus minimizing the risk of false-negatives on PCR-based seed health testing.
