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.

Poluição sonora é toda emissão de som que direta ou indiretamente seja ofensiva ou nociva à saúde da coletividade. Nas últimas décadas, a poluição sonora tem afetado os cidadãos das cidades em amplo desenvolvimento, pois além do aumento da frota de veículos (proporcionado por incentivo do governo às indústrias automobilísticas), houve uma ampliação da malha urbana das cidades. O ruído excessivo pode causar muitos problemas à sociedade, como distúrbios do sono, má compreensão da palavra falada, propensão à irritabilidade e, em casos extremos, a perda de audição. Com foco nessa problemática, a presente pesquisa objetivou diagnosticar e avaliar as causas e efeitos que a exposição a níveis de ruído provoca em cidadãos que trabalham ou mesmo que apenas transitam nas principais vias urbanas da cidade de Umuarama-PR. A metodologia utilizada foi aplicar um questionário diagnóstico em 14 localidades da cidade para 441 pessoas. Tal questionário englobava 11 perguntas e foi distribuído no mês de junho de 2015, em 03 turnos (manhã, tarde e noite). No geral verificou
