Introduction of bee by-products, such as honey, pollen, and propolis, while also being in accordance with the precepts of sustainable The pollination exercised by stingless bees in the natural resource use (Absy et al., 2013). Amazon is considered to be a great ecological benefit to this The genus Melipona Illiger is only found in Neotropical biome. The Amazon region contains a rich fauna of these America – South America, Central America, and the Caribbean insects, guaranteeing the production of fruits and seeds through Islands –, being most diversified in the Amazon basin (Michener, pollination, and promoting the conservation of plant species 2007). In this group can be found the principal native stingless and the survival of their colonies (Ferreira & Absy 2017a, b; bees used in the practice of meliponiculture in the Amazon Absy et al., 2018; Rezende et al., 2019). region (Brito et al., 2013; Ferreira & Absy 2017a). These Meliponiculture is an activity that has been gaining bees are popularly known as jandaíra, jandaíra-preta, and prominence in the Northern region of Brazil, because it exploits jandaíra-da-Amazônia, names that can be attributed to numerous the potential of native flora and helps to generate income different species of meliponines, depending on the region through family farming, allowing for the commercialization (Nogueira-Neto, 1997; Silveira et al., 2002; Oliveira et al., Open access journal: http://periodicos.uefs.br/ojs/index.php/sociobiology ISSN: 0361-6525 Sociobiology 67(2): 268-280 (June, 2020) 269 2013).

Diversos insetos são Anna Maria Amorim Silva1 mencionados como inquilinos das colmeias dessa abelha, alguns deles apenas Victor Hugo Pedraça Dias2 como comensais, outros prejudiciais. O objetivo deste estudo foi de identificar a 3* fauna de artrópodes encontrada no interior de colmeias da abelha jandaíra (M. Daniel Santiago Pereira subnitida) na região de Mossoró, RN. O trabalho foi realizado no mês de agosto a Paulo Roberto Menezes4 setembro de 2005, no meliponário Monsenhor HUBERTO BRUEINING. Foram Marcos Antonio Filgueira5 demarcadas de forma aleatória 40 colmeias.
