Abstract Known as the diamondback moth, Plutella xylostella L. is registered as one of the most important pests of Brassicaceae in the world. It is characterized as a specialized insect in this family, due to specifics for feeding. However, based on reports from producers, the shoots of sour passion fruit in the extreme south of Santa Catarina, were damaged by a phytophagous insect attack. The damage plants were collected and from this, it was possible to identify the specie P. xylostella as the insect causing the damage. Therefore, the purpose is to communicate a new record of phytophagous insect associated with passion fruit, as well as a new host outside the list of Brassicaceae for P. xylostella. The collected shoots had amber exudation and sawdust appearance in the axils of leaf growth, the plants had wilted leaves and emission of lateral shoots. It is believed that the individuals have managed to complete the life cycle in the plant because of the similarity in the nitrogen compounds present in the species of Brassicaceae and Passifloraceae.

Abstract The aim of this study was: (i) understand how upstream signaling modulated TOR-SnRK1 nexus; and (ii) establish an interplay between SnRK1-TOR nexus, sugar availability, sucrolytic enzyme activities, expression level of key genes related to signalling and sugar metabolism, including trehalose, in in vitro-grown of ‘Myrobalan 29C’plum rootstock (Prunus cerasifera). Explants were cultivated in Murashigue and Skoog medium (MS) with trehalose (0; 1,0 and 10 mM). In 3 days, the antagonistic role of PcSnRK1 and PcTOR was confirmed in plants treated with 10mM trehalose, possibly indicating that ‘Myrobalan 29C’ was not in a stress condition. Furthermore, a PcTREA up-regulation was observed, which can lead to glucose accumulation, that in turn is precursor of sorbitol synthesis. Regarding the growth parameters evaluated after 21 days of in vitro culture, the uppermust number of shoots and explant length was observed at 10mM trehalose. Such positive response may be due to an increase in Glucose and UDP-Glc content, direct products of sucrose synthase (SuSy) enzyme. Consistent with these results, the highest availability of these molecules may be the upstream signal for TOR-activation. Interestingly, in this same condition, a sucrose accumulation was observed, which may also have contributed to PcTOR up-regulation and ameliorate in growth parameters.

Abstract The objective was to evaluate gas exchange and the leaf area requirement for yield in Cavendish and Gros Michel bananas. The cultivars Grande Naine, Calipso, Bucaneiro, FHIA-17 and FHIA-23, and two production cycles, were arranged in a completely randomized experimental design, in a factorial scheme, with five replicates. For the physiological characteristics, a 5x9x2 factorial arrangement was considered, with cultivars, evaluation periods and reading times. Cultivars Bucaneiro and Calipso require larger leaf area per unit produced and FHIA-23, smaller, which suggests a greater photosynthetic efficiency per leaf unit for FHIA-23, confirmed by the higher masses of bunches and hands and greater numbers of hands and fruits. Gas exchange varies with cultivars, evaluation periods and reading times. Cultivars FHIA-17 and Calipso, Gros Michel type, respectively showed higher photosynthesis and transpiration rates than Grande Naine, Cavendish type. Net photosynthesis, stomatal conductance, quantum efficiency of photosynthesis, instantaneous water use efficiency and carboxylation efficiency are higher at 8:00 h than at 14:00 h. The month of June allowed the cultivars to express the highest values of photosynthesis rates, incident radiation on leaves, carboxylation efficiency and stomatal conductance.

Abstract In Mexico, Annona purpurea Moc. &Sessé ex Dunal, chincuya is found in mountains and family gardens. It is used as food (fruits), traditional medicine (leaves, stems, roots, seeds, bark), wood in construction, papermaking, carpentry, rope making, and as fuel. There is not enough information on the seed, nor on germination management, which is scarce, prolonged and erratic. Considering that the morphophysiological dormancy is the probable cause, it was necessary, within a broader project, to start with the characterization of the seed and determine the effect of dry warm storage (DWS) on it. The perimeter and length of the embryos increased due to the increase in length of the cotyledons and the hypocotil root axis, while the middle hypocotyl area decreased, forming an acinturated embryo. These data indicate that the embryos of chincuya are underdeveloped since they grew and modified their shape, due to the effect of DWS, until the 6th month. This development of the embryo within the seed during dry warm storage confirms the presence of morphological dormancy. This is the first report of embryo growth and characterization of chincuya seeds.

Abstract The objective was to evaluate the residual action of the insecticides acetamiprid + etofenprox, spinetoram, indoxacarb and methoxyfenozide on the predator Chrysoperla externa Hagen, 1861 (Neuroptera: Chrysopidae). The bioassays followed the methodologies proposed by the International Organization for Biological and Integrated Control (IOBC). The insecticides were sprayed on grapevine plants cv. Burgundy, using the maximum recommended field dosage for fruit trees. Larvae and adults of the predator were exposed to leaves containing the insecticide residues, at 3, 10, 17, 24 and 31 days after spraying, to determine the residual effect on the following biological parameters: mortality, fecundity and fertility. Based on the toxicity observed during the bioassays, the insecticides were classified according to the IOBC persistence scale. Spinetoram was classified as moderately persistent to larvae and slightly persistent to adults, indoxacarb also he was consideredpersistent for larvae and as a short-lived for the adult stage of the lacewing, thus showing the difference in susceptibility between the stages of development of C. externa. The insecticides acetamiprid + etofenprox and methoxyfenozide are the most suitable for ecologically safe application, in areas where the predator occurs because they are classified as short-lived insecticides for the larval and adult stages of C. externa.

Abstract Cerconota anonella (fruit borer) and Bephratelloides pomorum (seed borer) are the main pests of Annonaceae and knowing their population dynamics is essential to establish their management in orchards of these crops. The objective of this study was to evaluate the influence of native vegetation on the population of fruit and seed borers in two production seasons in an atemoya orchard in the semiarid region. The study was carried out in a commercial atemoya orchard in Janaúba, MG. The experimental area was divided into two parcels and, in each of them, the distance from the experimental plots to the surrounding vegetation, of approximately 10m, 33m, 57m and 81m, was recorded. The sampling of insects was carried out at different periods, spring and summer, through the collection, every two weeks, of atemoya fruits containing attack signs by the borers. The intensity of infestation of each borer species was determined. The intensity of borer infestation varies between seasons, with fruit borer infestation in summer and seed borer infestation in spring. The distance from the orchard to the adjacent vegetation does not interfere with the infestation intensity of fruit and seed borers.

Abstract The Embrapa Cerrados pitaya breeding program developed five superior genotypes of different species. The objective of this work was to evaluate the yield capacity of these five pitaya genotypes under the edaphoclimatic conditions of the Federal District. The experiment was carried out at the Embrapa Cerrados in Planaltina, DF. The five selected pitaya genotypes were evaluated, as well as a parent genotype used in the breeding program. Length (CF), diameter (DF) and mass (MF) of all fruits were evaluated, as well as the length/diameter ratio (CF.DF-1), number of fruits per plant (NF.PL-1), production per plant (kg.PL-1) and estimated productivity (t.ha-1). BRS Luz do Cerrado and BRS Lua do Cerrado presented larger and heavier fruits, while BRS Minipitaya do Cerrado presented the smallest fruits. CPAC Roxa and BRS Granada do Cerrado presented more rounded fruits. BRS Granada do Cerrado had the highest yield capacity in the two evaluated crops. The results obtained prove the importance of genetic breeding and the selection of superior genotypes more adapted to the region of cultivation, in order to guarantee greater profitability and products of better quality to rural producers and consumers.

Abstract The management of organic fertilization in passion fruit has been carried out empirically based on the responses of the crops and the experience of farmers. Knowledge of the physiological responses of plants to organic fertilizers is essential to optimize fertilization programs. The objective of this study was to evaluate the differential expression of genes coding for nitrate transporters as well as plasma membrane H+-ATPase in passion fruit seedlings treated with different organic fertilizers in the presence or not of humic acids. The equivalent of one gram of total nitrogen dissolved in water from cattle manure, castor oil cake and urea were added and the seedlings were treated or not with a suspension of humic acids (2 mmol/L). Differential expression of low and high affinity nitrate transporters (PeNRT2.2 and PeNRT1.1 PeNRT2.2e) and H+-ATPase (PeMha) was performed by qRT-PCR. The use of cattle manure increased the differential expression of the high affinity transporter regarding to the control. The application of humic acids amplified the increase observed in the differential transcription of the high-affinity transporter with manure and urea fertilization, with no effect observed with the use of castor oil cake. Humic acids induced transcription of the gene encoding H+-ATPases in all treatments compared to control. The application of biofertilizer based on humic acids in low concentrations directly on the plant can be used with the objective of optimizing the organic fertilization of passion fruit with cattle manure and urea.

Abstract Pineapple is the most exported tropical fruit in the world in terms of volume. This study aimed to comprehensively analyze the scientific publications on pineapple, with an emphasis on the agricultural sciences. 7,885 documents published between 1893 and 2022 (February 22nd), 2,350 of which belonged to the agricultural sciences, were retrieved from the Scopus-indexed database to be analyzed using the word pineapple. VOSviewer software was used for a bibliometric network analysis using author keyword mapping. 78.2% of the documents were articles, with an increase in the volume of publications over time. The scientists were from 138 countries, with India, the United States, and Brazil accumulating 36.2% of the total number. The research has focused on topics such as chemistry, food technology (primarily juice), the use of pineapple as a medicinal plant, and the clinical benefits of its main enzyme (bromelain). Scientists in the chemical field reported more research than in the agricultural and biological areas due to the properties of the fruit. Our results indicate that few studies focus on rural extension or technology transfer to growers. More efforts should be made to help local pineapple growers improve their yields and attain a sustainable and more environmentally friendly approach to the production of this fruit.

This study aimed to comprehensively analyze the scientific publications on pineapple, with an emphasis on the agricultural sciences. 7,885 documents published between 1893 and 2022 (February 22nd), 2,350 of which belonged to the agricultural sciences, were retrieved from the Scopus-indexed database to be analyzed using the word pineapple. VOSviewer software was used for a bibliometric network analysis using author keyword mapping. 78.2% of the documents were articles, with an increase in the volume of publications over time. The scientists were from 138 countries, with India, the United States, and Brazil accumulating 36.2% of the total number. The research has focused on topics such as chemistry, food technology (primarily juice), the use of pineapple as a medicinal plant, and the clinical benefits of its main enzyme (bromelain).

Abstract Artificial pollination is a prerequisite to achieve a sufficient yield of palm trees; hence the identification of superior male palm trees as a standard pollen source for date palm growers has a high priority. The current study was carried out to assess phenotypic diversity among four date palm males namely Hayani, Meghal, Fardh, and Ghannami Ahmer. The genetic diversity and phylogenetic relationships between palm genotypes were performed using eighteen quantitative morphological parameters of both vegetative and reproductive parts (leaf, leaflets, spines, and spathe). Principal components analysis and hierarchical clustering was performed to identify the differences and similarities between the studied genotypes. Results showed significant differences in morphological parameters between the four male palm trees. Most of the selected morphological parameters could be used as quantitative markers for the identification of date palm male genotypes. Principal component analysis showed that, the studied parameters formed two major homogeneous groups of variables, which possessed a high proportion of the observed phenotypic diversity among the studied date palm males. Cluster analysis showed that Fardh, Ghannami Ahmer, and Meghal, are closer related than Hayani; Ghannami and Fardh males showed the highest genetic similarity while the lowest similarity index was detected between Hayani and Ghannami Ahmer males.
