Ataque de Trigona spinipes (Fabr.) (Hymenoptera: Apidae: Meliponinae) em pitaia Hylocereus undatus (Haw.) e Hylocereus polyrhizus (Weber) (Cactaceae) em Couto de Magalhães de Minas, Minas Gerais, Brasil

Abstract

Resumo. A pitaia Hylocereus spp. (Cactaceae) é uma espécie frutífera exótica com cultivo em fase de expansão no Brasil. Problemas com pragas ainda são poucos relatados. Com isso, o objetivo deste trabalho foi relatar a ocorrência da abelha arapuá Trigona spinipes (Fabr.)(Hymenoptera: Apidae) em espécies de pitaia Hylocereus undatus (Haw.) e Hylocereus polyrhizus (Weber) no município de Couto de Magalhães de Minas, Minas Gerais, Brasil. Os danos principais decorrentes do ataque ocorrem nos frutos maduros, depreciando o fruto para comercialização. Este registro demonstra que T. spinipes necessita ser monitorada pelo potencial causador de danos significativos em pitaia e consequentemente perdas na produção.Attack of Trigona spinipes (Fabr.) (Hymenoptera: Apidae: Meliponinae) in dragon fruit Hylocereus undatus (Haw.) and Hylocereus polyrhizus (Weber) (Cactaceae) in Couto de Magalhães de Minas, Minas Gerais State, BrazilAbstract. The dragon fruit Hylocereus spp. (Cactaceae) is an exotic fruit species with crop in expansion phase in Brazil. Problems with pests are still few reported. The objective of this work was to report the occurrence of the Trigona spinipes (Fabr.) (Hymenoptera: Apidae) bee on the dragon fruit species Hylocereus undatus (Haw.) and Hylocereus polyrhizus (Weber) in the municipality of Couto de Magalhães de Minas, Minas Gerais State, Brazil. The main damages resulting from the attack occur in the mature fruits, depreciating them for commercialization. This record demonstrates that T. spinipes needs to be monitored for the potential to damage dragon fruit and consequently production losses.

POPULATION FLUCTUATION OF Trigona spinipes (Fabricius, 1793) IN PEACH TREE AT THE EXPERIMENTAL STATION OF EPAMIG, MARIA DA FÉ, MG

“…For example, the study carried out by (BOIÇA JR; SANTOS; PASSILONGO, 2004) investigated the population fluctuation of T. spinipes bees in seven varieties of passion fruit and found that the presence of these insects resulted in a significant decrease in the number of fruits produced. Similar results were observed in the planting of dragon fruit (Hylocereus undatus and Hylocereus polyrhizus) (ALVES et al, 2018). These studies suggest that the role of T. spinipes in pollination may vary according to the specific crop and its interactions with other species.…”

“…T. spinipes jaws cut the tissues of the plants causing a release of certain secretions, resins or brous laments for the construction of their nests in the branches of the trees or, in abandoned termite mounds (Moura et al 2017). In addition to the injuries caused by the direct attack of this insect, such as destruction of ower buds, new branches, owers and fruits (Gallo et al 2002), the exposure of tissues can allow the entry of pathogens, causing even greater problems in production (Alves et al 2018).…”
