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.

Plantas de oliveira Olea europaea L. (Oleaceae) foram introduzidas no município de Diamantina, Minas Gerais, Brasil devido ao potencial local para produzir azeitonas e azeite, fruto e processado com mercado mundial em expansão. O objetivo deste trabalho foi registrar, pela primeira vez, a presença da cochonilha negra, Saissetia oleae (Olivier) (Hemiptera: Coccidae), em oliveiras (cv. Ascolano) em Diamantina. O presente registro mostra que S. oleae precisa ser monitorada, quando da implantação de viveiros de mudas e áreas de cultivo nesta região, por ter potencial para causar danos severos nas plantas e perdas na produção. Occurrence of Black Scale Saissetia oleae (Hemiptera: Coccidae) in Olive Olea europaea (Oleaceae) cv. Ascolano in Diamantina, Minas Gerais State, Brazil. Abstract. Olive plants Olea europaea L. (Oleaceae) were introduced in the Diamantina region, Minas Gerais State, Brazil mainly because it is a potential place to produce olives and olive oil, with growing global market. The aim of this study was to record the presence of black scale Saissetia oleae (Olivier) (Hemiptera: Coccidae) on olive (cv. Ascolano) in Diamantina. This record shows that S. oleae needs to be monitored when deploying nurseries and crop areas for its potential to cause severe damage in plants and production losses.

Dragon fruit Hylocereus polyrhizus  and Hylocereus undatus are familiy of cactus, grown in Malang. The high consumption of dragon fruit, have an impact on the fruit skin buildup that simply disposed of as trash. Dragon fruit skin is known to have a source of natural red dye, which is Betacyanin. The purpose of this study was to determine the characteristics of the dragon fruit peel extract Betacyanin Hylocereus polyrhizus and Hylocereus undatus as well as the stability of the organoleptic jelly, which will be developed into a learning materials atlas for class VIII Junior High School. The study was conducted in September-October 2015. The study was conducted in three stages. This type of research phase I and II is True Experimental, and phase III is development. The results of phase I shows that various concentrations of ethanol (70% and 90%) have an effect on the characteristics of the extract Betacyanin skin dragon fruit Hylocereus polyrhizus and Hylocereus undatus, but very significant effect on skin extract dragon fruit Hylocereus undatus the treatment of N2, EI at pH 4,5. Later in the phase II study results showed that different concentrations of extracts of the best Betacyanin significantly affect the organoleptic stability of jelly. The results of phase III is the development of phase I and II studies into Atlas media for 8th grade of  Junior High School.

AbstractThis study aimed to characterize the new fungal disease on the stem of red-fleshed dragon fruit (Hylocereus polyrhizus) in Malaysia, which is known as gray blight through morphological, molecular and pathogenicity analyses. Nine fungal isolates were isolated from nine blighted stems of H. polyrhizus. Based on morphological characteristics, DNA sequences and phylogeny (ITS, TEF1-α, and β-tubulin), the fungal isolates were identified as Diaporthe arecae, D. eugeniae, D. hongkongensis, D. phaseolorum, and D. tectonendophytica. Six isolates recovered from the Cameron Highlands, Pahang belonged to D. eugeniae (DF1 and DF3), D. hongkongensis (DF9), D. phaseolorum (DF2 and DF12), and D. tectonendophytica (DF7), whereas three isolates from Bukit Kor, Terengganu were recognized as D. arecae (DFP3), D. eugeniae (DFP4), and D. tectonendophytica (DFP2). Diaporthe eugeniae and D. tectonendophytica were found in both Pahang and Terengganu, D. phaseolorum and D. hongkongensis in Pahang, whereas D. arecae only in Terengganu. The role of the Diaporthe isolates in causing stem gray blight of H. polyrhizus was confirmed. To date, only D. phaseolorum has been previously reported on Hylocereus undatus. This is the first report on D. arecae, D. eugeniae, D. hongkongensis, D. phaseolorum, and D. tectonendophytica causing stem gray blight of H. polyrhizus worldwide.

Abstract The objective of this work was to evaluate the viability of the micrografting of yellow dragon fruit (Selenicereus megalanthus) on different rootstocks, based on DNA content and anatomical analyses. The used rootstocks were: yellow dragon fruit, white dragon fruit (Hylocereus undatus), Saborosa (Selenicereus setaceus) dragon fruit, and the Cebra and Orejona red dragon fruit (Hylocereus polyrhizus) varieties. The experimental design was completely randomized with five treatments and four replicates of five plants. After 30 days of cultivation, the following traits were evaluated: length and diameter of the micrografts and microrootstocks; and root length, percentage of setting, and fresh mass of the micrografts. Flow cytometry analyzes were performed before and after micrografting to verify genetic stability and the occurrence of endoreduplication. In addition, histological sections were made in the micrografting region to verify the connections of vessels and tissues between the graft and the rootstock. Endoreduplication was observed in all treatments. The amount of DNA in the yellow dragon fruit micrograft increased on the red Orejona variety. The presence of vessel connections was verified between the micrografts and microrootstocks. The yellow dragon fruit was also more vigorous when grafted on Orejona. Based on DNA content and anatomical analyses, in vitro yellow dragon fruit micrografting is feasible in all used rootstocks.

And Control

Polystyrene (PS) is one of the major plastics contributing to environmental pollution with its durability and resistance to natural biodegradation. Recent research showed that mealworms (Tenebrio molitor) and superworms (Zophobas morio) are naturally able to consume PS as a carbon food source and degrade them without observable toxic effects. In this study, we explored the effects of possible food additives and use of worm frass as potential plant fertilizers. We found that small amounts of sucrose and bran increased PS consumption and that the worm frass alone could support dragon fruit cacti (Hylocereus undatus) growth, with superworm frass in particular, supporting better growth and rooting than mealworm frass and control media over a fortnight. As known fish and poultry feed, these findings present worms as a natural solution to simultaneously tackle both the global plastic problem and urban farming issue in a zero-waste sustainable bioremediation cycle.
