Ethnoentomology studies can be important tools for the Productions of knowledge about the biological and cultural heritage of a region, which can be used for the valorization and cultural maintenance of a people as well as to assist in the maintenance of natural environments. Thus, this research aimed to record the traditional ethnoentomological knowledge of the residents of the Soledade community, in the municipality of Caxias, Maranhão. Data collection was carried out in two stages. In the first stage, recon- naissance of the study area and presentation of the project to the community were conducted, and in the second stage, semi-structured interviews were conducted. The collected data were transcribed as faithfully as possible and organized into digital tables, with the assistance of Microsoft Word and Excel programs. For the data analysis regarding the most important local insects, the Importance Value (IVs) was calculated. Sixteen interviews were conducted, with the majority of the interviewees being female, aged between 41-72 years old, and most having only incomplete elementary education. For the interviewees, the ethnozoological domain "in- sect" can encompass 74 different animals, not always systematically classified in the class In- secta. Different uses were described, linked to food, medicine, leisure, mystical-religious prac- tices, and predictions of events. The most important local insects were ants and caterpillars, mainly identified for causing damage to the community's crops and plantations. Therefore, the importance of ethnobiological work in quilombola communities, as well as other traditional communities, is emphasized with the intention of preserving knowledge and also conducting research. 2024-02-21T00:00:00Z https://repositorio.uema.br/jspui/handle/123456789/6055 Título: Fauna de flebotomíneos (díptera: psychodidae) e morfometria geométrica das asas de lutzomyia longipalpis (Lutz e Neiva, 1912) de áreas antropizadas do município de Codó, Maranhão, Brasil Abstact: Sandflies (Diptera, Psychodidae, Phlebotominae)are insects involved in the transmissionof leishmaniasis, and anthropogenic actions have caused to the dispersion and adaptation of vector species inareas with humansettlements. The objective was to conduct an entomological survey and analyze the morphometry of Lu.longipalpis wings in two areas in the city of Codó, Maranhão.Sandflies were collected intradomicile and peridomicile between October 2020 and January 2021.A total of 17,796 sandflies were captured, 17.89% in São Francisco and 82.11% in Montevidéo, distributedin five generaand six species. The abundance was higher in the rural area (82.1%), with the species Lu. longipalpis (rural=96.80% / urban=99.47%) and Ev. evandroi (rural=2.32% / urban= 0.28%) were the most abundant in both areas. The most frequent type of environment for sandflies was the peridomicile (94.56%). The type of chicken bait (rural=92.3%/urban=79.5%) had a higher occurrence of sandflies in both areas. The months of December and January showed a greater abundance of captured sandflies, coinciding with a decrease in temperature and an increase in humidity in the environment. For morphometric analysis, 140 specimens (60 females and 80 males) of Lu.longipalpis were used and all analyzes were performed separately by sex. Regarding the analysis of wing morphometry, wing anomalies were foundin two female specimens from Montevidéo.The canonical variables did not separate groups of male and female specimens, but the centroid size of male specimens from SãoFrancisco 1S was significantly larger than the other groups.Studies of the phlebotomine fauna contribute to more efficient measures for disease prevention and vector control, and data on the geometric morphometry of Lu. longipalpis will be a source of knowledge for future studies in the city of Codó, Maranhão. 2023-07-18T00:00:00Z https://repositorio.uema.br/jspui/handle/123456789/6043 Título: Efeito da antropização sobre a diversidade da macrofauna edáfica em diferentes áreas do município de Caxias-MA Abstact: Soil is a non-renewable natural resource, where living organisms of great importance are found, such as soil macrofauna, living beings that comprise the phyla Annelida, Arthropoda and Mollusca. Soil macroinvertebrates actively participate in the environment they inhabit, but they can suffer directly from climate changes and anthropogenic actions. Based on the above, the present study aimed to understand the influence of human actions on the diversity of soil macrofauna in areas of the municipality of Caxias, MA. For this purpose, the diversity of soil macrofauna at the Universidade Estadual do Maranhão, campus deCaxias (intensely anthropized area) and the Área de Proteção Ambiental do Inhamum (conserved area), both in the municipality of Caxias, MA, was studied and compared. Two collections were carried out (one in the rainy season and the other in the dry season) with the use of 20 pitfall traps distributed at a distance of seven meters from each other and in a zig-zag shape. The collected specimens were taken to the Laboratório de Entomologia Aquática na Universidade Estadual do Maranhão, CampusCaxias, for identification, data tabulation and statistical analysis. In total, 4327 specimens from 10 orders, 39 families of Hexapoda, Arachnida and Myriapoda were sampled. Thegreatest abundance of sampledspecimens occurred during the rainy season in both areas. The conserved area presented higher diversity and equitability indexes, as well as a lower dominance index, which demonstrates that its community is more diverse and has a greater balance between taxa. Formicidae was the most abundant and dominant family in both areas and in both periods. The resultsof the present study reinforce the need to conserve natural environments to conserve the greatest diversity of soil macrofauna, as well as the negative effect of anthropogenic actions on this fauna. 2024-02-20T00:00:00Z https://repositorio.uema.br/jspui/handle/123456789/6042 Título: Ocorrência e caracterização dos habitats de Aedes aegypti (Linnaeus, 1762) e Aedes albopictus (Skuse, 1894) nos períodos seco e chuvoso, no povoado Barriguda, zona rural do município de Caxias, Maranhão Abstact: Aedes aegypti (Linnaeus, 1762) and Aedes albopictus (Skuse, 1894) are vectors of important arboviruses such as dengue fever, Zika fever and chikungunya fever,which cause serious public health problems worldwide. The aim was to verify the occurrence, characteristics and habitat location of A. aegypti and A. albopictus in residential and wild areas in dry and wet seasons in the village of Barriguda, rural area of Caxias, Maranhão. The collection of juveniles and alates was carried out in 20 residences, ten of them on the sides of MA 034 and ten residences closest to areas with denser vegetation in the dry season (September to December 2022) and in the wet season (January to April 2023). A total of 677 specimens of A. aegypti and A. albopictus larvae and pupae were collected, with the highest frequency in December(297; 43.9%)followedby February (156; 23%). A. aegypti scored higher positivity with 537 compared to A. albopictus; 79.3%. Thirteen positive containers were found with immature A. aegypti and A. albopictus, with the highest positivity in the water storage group at 71.4% in the dry season and 50% in the wet season, with the frequency in buckets (75%) being higher. Juveniles in plasticbuckets (46.1%) and rubber tires (38.5%) predominated, most of them in the shade (61.5%) and with organic material (leaf debris and moss) (92.3%). Ten winged specimens were collected, eight A. aegypti and two A. albopctus, five were found in space, and seven specimens were collected with a height of 0–50 cm. This study made it possible to obtain data on the behavior of the vectors A. aegypti and A. albopictus, which can help fight these vectors and thus reduce the spread of arboviruses, including dengue fever 2026-07-18T00:00:00Z
