Aggregation Pheromones of Weevils (Coleoptera: Curculionidae): Advances in the Identification and Potential Uses in Semiochemical-Based Pest Management Strategies BANDEIRA, PAMELA TAISLINE; FÁVARO, CARLA FERNANDA; FRANCKE, WITTKO; BERGMANN, JAN; Paulo Henrique Gorgatti Zarbin JOURNAL OF CHEMICAL ECOLOGY, v. 47, p. n/a 2021 DOI Palavra-chave: feromônios; controle de pragas Áreas do conhecimento: Ciências Exatas e da Terra; Química; Química Orgânica; Química dos Produtos Naturais; Ciências Exatas e da Terra; Química; Química Orgânica; Evolução, Sistemática e Ecologia Química resumo ... With approximately 83,000 species described, Curculionidae is the largest family of beetles, comprising more than 80% of all weevil species worldwide. Many species of Curculionidae attack a wide range of native and orchards crops, as well as globally important stored products such as grains, flour, and seeds, being responsible for significant environmental and economic losses. This work provides an overview of the research in the identification of aggregation pheromones of Curculionidae, and their potential contributions to the development of semiochemical-based pest management strategies. The synergistic effect of the host plant volatiles in the attractiveness of weevil pheromones is also briefly reported, demonstrating the important role of these additional attractants in the chemical communication of curculionids.

An Approach for the Generation of Multi-Objective Algorithms Applied to the Integration and Test Order Problem Giovani Guizzo; Thaina Mariani; Silvia Regiina Vergilio; Aurora Trinidad Ramirez Pozo JOURNAL OF SOFTWARE ENGINEERING RESEARCH AND DEVELOPMENT, v. 9, n. 1, p. 4:1-4:18, 2021 DOI Palavra-chave: hiper-heuristica; otimização multiobjetivo; Teste de Software Áreas do conhecimento: Ciências Exatas e da Terra; Ciência da Computação; Metodologia e Técnicas da Computação; Engenharia de Software resumo ... (en) Multi-Objective Evolutionary Algorithms (MOEAs) have been successfully applied to solve hard real software engineering problems. However, to choose and design a MOEA is considered a difficult task, since there are several parameters and components to be configured. These aspects directly impact the generated solutions and the performance of MOEAs. In this sense, this paper proposes an approach for the automatic generation of MOEAs applied to the Integration and Test Order (ITO) problem. Such a problem refers to the generation of optimal sequences of units for integration testing. The approach includes a set of parameters and components of different MOEAs, and is implemented with two design algorithms: Grammatical Evolution (GE) and Iterated Racing (irace). Evaluation results are presented, comparing the MOEAs generated by both design algorithms. Furthermore, the generated MOEAs are compared to two well-known MOEAs used in the literature to solve the ITO problem. Results show that the MOEAs generated with GE and irace perform similarly, and both outperform traditional MOEAs. The approach can reduce efforts spent to design and configure MOEAs, and serves as basis for implementing solutions to other software engineering problems.

An integrated assessment of the impacts of PM2.5 and black carbon particles on the air quality of a large Brazilian city GIDHAGEN, LARS; WOLF, ALYSON; ALONSO, MARCELO; SEGERSSON, DAVID; CASTELHANO, FRANCISCO J.; AMORIM, JORGE H.; Francisco de Assis Mendonça; KRECL, PATRICIA; TARGINO, ADMIR CRÉSO; POLEZER, GABRIELA; GODOI, RICARDO H.

Data on airborne fine particle (PM2.5) emissions and concentrations in cities are valuable for traffic and air quality managers, urban planners, health practitioners, researchers, and ultimately for legislators and decision makers. Emissions and ambient concentrations of PM2.5 and black carbon (BC) were assessed in the city of Curitiba, southern Brazil. The methodology combined a month-long monitoring campaign with both fixed and mobile instruments, development of emission inventories, and dispersion model simulations on different scales. The mean urban background PM2.5 concentrations during the campaign were 7.3 μg m−3 in Curitiba city center, but three- to fourfold higher (25.3 μg m-3) in a residential area on the city’s outskirts, indicating the presence of local sources, possibly linked to biomass combustion. BC concentrations seemed to be more uniformly distributed over the city, with mean urban background concentrations around 2 μg m−3, half of which due to local traffic emissions. Higher mean BC concentrations (3–5 μg m-3) were found along busy roads. The dispersion modeling also showed high PM2.5 and BC concentrations along the heavily transited ring road. However, the lack of in situ data over these peripheral areas prevented the verification of the model output. The vehicular emission factors for PM2.5 and BC from the literature were found not to be suitable for Curitiba’s fleet and needed to be adjusted. The integrated approach of this study can be implemented in other cities, as long as an open data policy and a close cooperation among regional, municipal authorities and academia can be achieved.
