“…It is important to note that the great variation of the physical and chemical characteristics of the pequi fruits from the different regions studied may occur due to differences in the climate, soil fertility and pH, annual rainfall, and other environmental conditions observed in the Brazilian Savanna biome (Novaes et al, 2013).…”

“…No entanto, a exploração da maioria de suas plantas nativas está ocorrendo de maneira predatória e não sustentável, ameaçando a preservação das espécies, o que torna o estudo delas de grande importância para manejo adequado e melhor aproveitamento na alimentação humana (BATLLE-BAYER et al, 2010;NOVAES et al, 2013).…”

ResumoO pequi é um fruto nativo do Cerrado que apresenta uma grande diversidade em suas características físicas e químicas. Estudos com frutos oriundos de diferentes ambientes de Cerrado são escassos na literatura. O objetivo deste estudo foi analisar as características físicas e nutricionais de frutos de pequizeiro oriundos dos estados de Tocantins (TO), Goiás (GO) e Minas Gerais (MG). Realizou-se a caracterização física de 30 frutos de pequi selecionados aleatoriamente, por estado, e determinou-se a composição química de sua polpa. Os frutos de pequi oriundos de MG apresentaram valores elevados para características físicas de importância comercial, como massa dos frutos, massa da polpa e rendimento de semente (amêndoa). Entretanto, os frutos oriundos de GO apresentaram alto rendimento de polpa. Foi observado conteúdo reduzido de lipídios nos frutos de TO (8 g.100 g -1 ), ao contrário dos frutos provenientes de GO e MG (24 e 26 g.100 g -1 , respectivamente). Em relação ao conteúdo de minerais, a polpa de pequi dos três estados constitui fonte de ferro, zinco, fósforo e magnésio, e a polpa de pequi oriundo de TO apresentou teor considerável de cálcio (107 mg.100 g -1 ). Conclui-se que a região de origem infl uencia nas características físicas e químicas dos frutos, sobretudo no rendimento de polpa, nos teores de umidade e lipídios, na densidade energética e no conteúdo de cálcio da polpa de pequi. Esses resultados indicam a necessidade de caracterização da região de origem e das espécies de pequizeiro para a comercialização dos frutos e utilização da polpa como matéria-prima nutritiva em diferentes sistemas alimentares.

SummaryPequi is a native fruit from the Brazilian Cerrado with a great diversity in its physical and chemical characteristics. Studies with fruits from different environments of the Cerrado are scarce. The objective of this study was to analyze, physically and nutritionally, pequi fruits from Tocantins (TO), Goiás (GO) and Minas Gerais (MG) States. The physical analysis of 30 pequi fruits, randomly selected by region, was carried out, and the chemical composition of their pulps was determined. The pequi fruits from MG showed high values of commercially important physical characteristics, as fruit mass, pulp mass and seed (almond) yield. However, fruits from GO showed high pulp yield. Low lipid contents (8 g.100g -1 ) were observed in the fruits from TO, on the contrary of the fruits from GO and MG (24 and 26 g.100g -1 , respectively). Regarding the mineral content, the pequi pulp from the three regions is a source of iron, zinc, phosphorus and magnesium, and the pequi pulp from TO showed considerable contents of calcium (107 mg.100g -1 ). The native region of the fruits infl uences their physical and chemical characteristics, mainly the pulp yield, moisture and lipid contents, energy density and calcium amount of the pequi pulp. These results indicate the necessity of characterization of the native region and...

“…The reasons for those different levels of susceptibility are not known, but could be due to plant defense factors (Painter, 1958;Price, 1986;Stout, 2013). According to Isman and Grieneisen (2014) plants developed complex chemical arsenals (terpenoids, flavonoids, tannins and alkaloids) with phytochemical activities that can act as deterrents to feeding or oviposition, reducing the performance of herbivores (Novaes, Molinillo, Varela, & Macías, 2013;Pavela, 2010;Rattan, 2010). Variability of leaf structures can also provide mechanical or physiological characteristics that can interfere with the ability of a particular mite species to use a plant as host.…”

The expansion of red palm mite (RPM), Raoiella indica (Acari: Tenuipalpidae) in Brazil could impact negatively the native plant species, especially of the family Arecaceae. To determine which species could be at risk, we investigated the development and reproductive potential of R. indica on 19 plant species including 13 native species to the Brazilian Amazon (12 Arecaceae and one Heliconiaceae), and six exotic species, four Arecaceae, a Musaceae and a Zingiberaceae. Values of the instantaneous rate of increase (ri) were initially estimated at 7, 14, 21 and 28 days after infestation of each species. Higher values of ri (> 0.05) were determined on the Arecaceae Adonidia merrillii, Astrocaryum jauari, Cocos nucifera, Bactris simplicifrons, Mauritia flexuosa, Phoenix dactylifera and Socratea exorrhiza, and on the Heliconiaceae Heliconia psittacorum Sassy; these were classified as “potential primary hosts”. Lower, but still positive values of ri (0-0.05) were determined on the Arecaceae Bactris maraja, Oenocarpus bacaba, Oenocarpus bataua and on the Musaceae Musa × paradisiaca (Prata variety); these were classified as “potential secondary hosts”. Negative values of ri were determined for the remaining plants, i.e., the Arecaceae Astrocaryum aculeatum, Attalea maripa, Bactris gasipaes, Elaeis guineensis, Euterpe oleracea, Euterpe precatoria, and the Zingiberaceae Alpinia rosea; these were considered “non-hosts”. Species with ri < 0.05 were considered not to be threatened by the RPM. Biological parameters of RPM were evaluated on the plant species with positive ri (except B. maraja) and two native species with negative ri (E. oleracea and E. precatoria). Mean developmental time ranged from 14.7 days on C. nucifera to 21.4 days on Musa × paradisiaca, showing a significant influence of the plant substrate. Immature viability, oviposition rate, net reproductive rate (R0) and intrinsic rate of increase (rm) were affected by the plant species.
