Calliphoridae and Mesembrinellidae include Diptera species that are good indicators of changes in forest environments. The present work aimed to inventory the Calliphoridae and Mesembrinellidae in Ilha Grande National Park and correlate the abundance of these organisms with environmental variables. Adult dipterans were collected during two expeditions in 2019 using two sampling methods, a Malaise trap and baited traps, distributed on two islands in the park. During the study, 1,007 individuals of 12 species of Calliphoridae and four species of Mesembrinellidae were collected. Family Calliphoridae was more abundant (97.12%). The abundance of native species showed a strong negative correlation with the abundance of the genus Chrysomya. Rodrigues Island (Island I) had higher diversity levels and no species of Chrysomya were recorded in this area, which may indicate a greater degree of environmental preservation. The results indicate that human action in natural environments can negatively impact species diversity, as found in Ilha Grande National Park that, historically, was partially occupied and is still in the process of regeneration.
Social wasps are insects that perform numerous environmental services, with emphasis on pollination and predation of agricultural pests. However, despite the increase in efforts to know the social wasps geographical distribution and richness, there are still many areas and ecosystems with few studies of this nature, such as the Paraná State, Southern Brazil. To collaborate with these efforts, this work aimed to carry out an inventory of social wasps in semideciduous forest in the Ilha Grande National Park, an integral conservation unit in the Paraná State. The Sampling took place from February to November 2019, totalizing 15 days and 60 hours, being carried out on six islands of the Paraná River, using the active search for species and colonies records. Fourteen species were registered, distributed in six genera. The study revealed a low species richness, which may be related to the area's usage history, as well as to other factors. This highlights the need for greater sampling efforts in other areas of this conservation unit.
O estado do Paraná situa-se como um importante polo do agronegócio e do setor agroindustrial nacional, com produção tanto no eixo alimentar quanto não-alimentar. No presente estudo, realizou-se o diagnóstico da produção agrícola do estado do Paraná com base nos dados consolidados do ano de 2018, investigou-se a contribuição de cada região intermediária do estado e realizou-se uma apresentação das principais possibilidades de valorização de resíduos agroindustriais. Por meio de dados do IBGE e IPARDES, as três principais culturas do estado do Paraná são a de cana-de-açúcar, soja e milho, seguindo a mesma tendência nacional, sendo o terceiro estado brasileiro com maior produção agrícola entre cultura temporárias e permanentes. Avaliou-se que a região de Curitiba é a que apresenta maior capacidade financeira do setor agroindustrial embora a região Noroeste do estado do Paraná seja a aquela que produz mais toneladas de grãos. Fato interpretado como a inclusão da região portuária do litoral do estado na região de Curitiba e a necessidade da instalação de mais agroindústrias no Noroeste do Estado. A compostagem, alimentação animal, biossorventes, compensados, compósitos, biocombustíveis e biotecnologia foram apontadas como possibilidades de valorização de resíduos agroindustriais, contribuindo para a sustentabilidade das cadeias produtivas. Dessa forma, espera-se com este trabalho favorecer o desenvolvimento do setor agroindustrial do estado do Paraná e divulgar as potencialidades de destinação de resíduos agroindustriais, completando o ciclo de beneficiamento agrícola.
Harvestmen are arachnids that play an important role in organic matter breakdown. However, there are many ecosystems in Brazil, including Conservation Units, which lack information about these organisms or are sub-sampled. Even in areas of Atlantic forest, a biome that hosts the greatest diversity and endemic rates of these arthropods in the world. In this perspective, the purpose of this study was to survey the harvestmen fauna in areas of Semideciduous Seasonal Forest in the Ilha Grande National Park, Paraná, southern Brazil, from February to November 2019, totaling 15 days and 60 hours, on six islands in the Paraná River. A total of 170 specimens was collected, distributed in five genera, comprising two species and three morphotypes. The low species richness may reflect the isolation of populations imposed by the island effect, however the study expanded the geographic distribution of Parapachyloides uncinatus and Discocyrtus invalidus, for which until then there was no record of occurrence in the Paraná State.
