Diversidade de insetos em duas áreas remanescentes de floresta amazônica em Manaus, Amazonas

Abstract

Insects represent the most diverse group of animals in number of species and are highly representative in the Amazon biome. All the types of natural and modified ecosystems, both terrestrial and aquatic, sustain communities of insects that present a variety of of lifestyles, forms and functions. Considering all this diversity and the interaction of these animals with people who frequent forest fragments urban areas, such as parks, and can promote education environmental analysis, it was proposed to analyze the entomofauna present in two areas Amazon forest remnants in the city of Manaus, capital of the state of the Amazon. Therefore, areas in the Municipal Park of the Mindu and on the campus of the Federal University of Amazonas, UFAM. Observations and records of insects were made using a camera from August 2018 to February 2020 in the Municipal Park of Mindu, and from August 2019 to February 2020 at UFAM. The extension of study sites was traversed through its trails and built-up areas. After the photographic records, identification was carried out according to order, family and species, when possible, with the help of literature and Prof. Zoological Collection Paulo Bührnheim – UFAM. In the Municipal Park of Mindu insects from 35 families distributed in ten orders were found, already at UFAM, insects from 38 families distributed in 11 orders were found. Considering that 30 orders of insects are known in Brazil, the numbers found are expressive in relation to this diversity. the order Lepidoptera had the highest number of species found, with 20 spp., followed by Hemiptera with 8 spp., Coleoptera and Hymenoptera with 4 spp. each. Knowing the composition of insects in these places provides the basis for studies futures on the relationships they have with flora, fauna and people in urban forest fragment environments. Area conservation forest remnants amid the growing urbanization of Manaus serves to maintain a more diverse entomofauna in this urban environment, where it is it can acquire food, contribute to the pollination of vegetation and serve as food for other animals in the food chain.
