Pitaya (Hylorereus sp.) is a fruit from the botanical family Cactaceae, originally from Latin America. In Brazil, pitaya cultivation is promising due to the fruit’s reputation of being nutritious and having many uses. This study’s objective was to analyze the economic viability of two pitaya production systems in Tomé-Açu municipality, the largest...

... that suggest a drop in pitaya productivity were not found in the literature, nor in the researched areas. In view of this, productivity was assumed-after attaining productive stability-to be constant during its useful life (20 years), for both the intensive (Figure 1) and extensive production systems (Figure 2). ...

... production starts with a total of 1600 kg ha -1 in the first year, followed by 8000 kg ha -1 in the second, then reaches productive stability in the third year, with 16 000 kg ha -1 (Figure 1). Extensive production starts with 834 kg ha -1 in the first year, then, unlike intensive production, reaches stability in the second year, with 16 680 kg ha -1 (Figure 2). Figure 2. Pitaya productivity curve for the extensive production system (kg ha -1 ) Source: Research data, 2019 Table 3 shows the cash flow for the intensive production system for each year, specifically, costs, the revenue generated by production, net cash flow (NCF), and accumulated cash flow (ACF). ...

... Dragon fruit species, originated from Central America, are found in different world regions (Tel-Zur, 2017). They were introduced in Brazil in the 1990s and cultivated mainly in the states of Minas Gerais, Pará, Santa Catarina, and São Paulo (de Loureiro et al., 2020). Some ant (Hymenoptera: Formicidae) species damaged flowers, fruits and stems of dragon fruit plants in Brazil, France, Indonesia, Mexico, Nicaragua, South Korea and Vietnam (Canto et al., 1993;Le Bellec et al., 2006;Choi et al., 2013;Sakdian et al., 2015;Marques et al., 2021 ant species and their role on the plants have to be identified to determine appropriate management strategies for these insects. ...
Ant species and their role on dragon fruit, Hylocereus undatus plants as possible mutualism, pests or pollinators are poorly known. This study aimed to identify ant species and their eventual injury on an urban plantation of dragon fruit in Sete Lagoas, state of Minas Gerais, Brazil. The ants collected on these plants were identified as Crematogaster evallans, Dorymyrmex brunneus, Dorymyrmex insanus and Linepithema neotropicum. Ants made holes and fed on flower buds, causing depreciation and abortion of dragon fruit flowers. After pruning, they also fed on fallen stem pieces of dragon fruit plants on the ground. Keywords: Dolichoderinae, injury, Myrmicinae.
