Guava orchards at Elfaki Hashim; North of Khartoum, (Khartoum State) and Elsawagi Elgenobia (Kassala State) in the middle and east of Sudan respectively were selected to assess the response of some Tephritids to water extracts (WE) of mango, guava, apple, cucumber, and ready-made juice of mango (Crystal<sup>®</sup>; Crystal Industrial Co. Ltd, Araak Group; <a href=""></a>) against Torula yeast (a standard fruit fly attractant) and water (control) baited in locally made traps. The trial was performed as Randomized Complete Block Design (RCBD) replicated 3 times for 5 consecutive weeks at each site. Highly significant differences were recorded between attractants and the interaction between attractants and times (weeks) on trapping different species of fruit flies. Five species of fruit flies; <em>Ceratitis capitata</em>, <em>Bactrocera dorsalis</em>, <em>Zeugodacus cucurbitae</em>, <em>Ceratitis cosyra,</em> and <em>Ceratitis quinaria</em>, were found to respond positively to all tested materials at both sites<em>.</em> The greatest number of <em>C. capitata</em> flies was caught by traps equipped with ready-made Crystal<sup>®</sup> mango juice at the Elfaki Hashim site. The mean number of <em>B. dorsalis </em>attracted to the WEs of mango and guava at Elsawagi Elgenobia site was statistically identical to that of the same species lured to Torula yeast, 83.7, 70.3, and 111.5 flies /trap/week, respectively. Attractants extracted from botanicals are cost-free and easily prepared by farmers for mass trapping of fruit flies. More studies regarding active ingredients, doses, and the number of traps utilized per area should be considered.</p> Mohammed E. E. Mahmoud, Mohamed A. Kambal, Sumaia M. Abukashwaa, Samira A.

For this, a chisel plow prototype was developed based on four vertical tillage parameters: (1. Working depth 2. Number of bodies 3. Spacing between chisels 4. Use of wings or sweepers). These parameters determined the criteria and dimensions of the prototype for its development in design parameters such as spacing, position, angle of attack and depth of work.</p> <p>The performance evaluation of the prototype was compared with the disc plow; an implement that served as a witness as it was the most widely used technology. The standardized test method was used by the National Center for Standardization of Agricultural Machinery "CENEMA". The results obtained show a prototype plow with five chisels mounted on a double platform frame. The front platform is used for the coupling of three shallow chisels and the rear one, for the coupling of two deep chisels with wings. The implement adjusts for two working depths 0.30 and 0.40 meters and two working widths 1.80 m and 2.40 m respectively. The performance evaluation showed that vertical tillage with the chisel plow prototype in its two treatments showed an average saving of more than 45% in the fuel consumption variable and 53% in the effective working time compared to conventional tillage used with a disc plow. In terms of quality of work, vertical tillage shows high performance in soil disturbance, exceeding up to 65% of the work done by conventional tillage. Finally, it is concluded that the proposed technology should be used as technological innovation and replace the conventional disk plow technology, given its technological, economic and environmental advantages.</p> M.

This situation induced land-use changes, and social reorganization has led to new approaches to natural resources management. Tenure issues in natural resources management limit the adoption of agroforestry systems and effective land use scale. This paper describes the species composition, structure, and diversity of woody species on agroforestry parklands at Tiogo under two types of land tenures. Ecological and structural characteristics of vegetation patches were computed to characterize the species composition. A variety of diversity measures were calculated to determine the heterogeneity for each type of land tenure. A total of 49 woody species belonging to 19 families and 38 genera were identified, of which 44 and 48 species were recorded in non-landowners’ farms and landowners' farms, respectively. Leguminosae, Combretaceae and Anacardiaceae were the most abundant families. The dominant species in agroforestry parklands were <em>Vitellaria paradoxa, Parkia biglobosa, Lannea microcarpa, Piliostigma reticulatum </em>and<em> Piliostigma thonningii.</em> Analyses of variance of the entire woody vegetation of agroforestry parklands revealed no significant differences in terms of all computed indexes but showed that the landowners’ farms were the most diverse than non-landowners farms. The density of stems ≥5 cm dbh and the basal area were higher in landowner’s farms than in non-landowners farms. In both types of farms, the size class distributions of the vegetation produced a reverse J-shaped curve, supporting that agroforestry parkland in Tiogo is dominated by young individuals. The spatial distribution of the seedling was mainly clumped, reflecting the dominance of clonal propagation. Security of land and tree tenure is a necessary condition for any land-based investment (planting and protection of preferred species and soil amendment). The challenge to maintain parklands’ tree biodiversity in “good” condition also needs to consider the flexibility of land tenure and equitability sharing of the benefits from trees.</p> Lassina Sanou, Jonas Koala, Souleymane Ouédraogo, Brama Ouattara Copyright (c) 2022 Lassina Sanou, Jonas Koala, Souleymane Ouédraogo, Brama Ouattara Fri, 11 Mar 2022 00:00:00 +0000 Performance of Management Interventions to the Impacts of Prosopis juliflora in Arid and Semiarid Regions of the Middle Awash Valley, Ethiopia <p>The objective of this paper is to provide up-to-date empirical information on the expansion of <em>P. juliflora</em>, its environmental and livelihood impacts, and the performance of past and current management strategies in the Middle Awash Valley (MAV), Ethiopia. This study was based on data collected using focus group discussion, key informant interviews, and field observation. The results show that <em>P. juliflora</em> has expanded rapidly and invaded valuable grazing and croplands, and settlement areas. The rapid expansion of <em>P. juliflora</em> in the study area is attributed to climate change (increased temperature and declined rainfall), its ecological competition, spreading of seeds by wild animals and pastoral (mobile livestock) livelihood system, and recent occurrences of flood and drought-induced pasture scarcity that has forced livestock to eat more <em>P. juliflora</em> seed pods. Also, delays in the use of land cleared for farming activity have created good opportunities for Prosopis expansion. The perception and views of people on the benefits of <em>P. juliflora</em> and management options vary according to livelihood systems and stakeholder types (e.g., environmental managers and pastoralists). The attempted management strategies to eradicate <em>P. juliflora</em> (cutting, burning, and bulldozering or converting into economic utilization by making charcoal, fodder, and furniture) failed to achieve the intended outcomes. These management interventions failed due to many reasons. Some of these were the rapid rate of <em>P. juliflora</em> expansion triggered by the recurrent drought, severe scarcity of pasture that forced livestock to eat <em>P. juliflora</em>’s seed pods and travel into new areas, inadequate technologies to aid utilization and eradication, inability to collect sufficient quantity of pods to produce fodder for livestock, and absence of sufficient and satisfactory markets for the end-product (fodder). The results generally imply the need for urgent policy and management interventions. This study also highlights important issues that should be considered in introducing and implementing management strategies in the future.</p> Mekonnen Adnew Degefu, Mohammed Assen, Roger Few, Mark Tebboth Copyright (c) 2022 Mekonnen Adnew Degefu, Mohammed Assen, Roger Few, Mark Tebboth Thu, 28 Apr 2022 00:00:00 +0000 Molecular Characterization of Mutations in Anticarsia gemmatalis Cadherin Gene and their Relation to Bacillus thurigiensis Resistance <p><em>Anticarsia</em> <em>gemmatalis</em> Hübner, 1818 is the main soybean defoliating pest in Brazil. The biological control of the species is done with products based on toxins produced by <em>Bacillus</em> <em>thurigiensis</em> (<em>Bt</em>), as bioinsecticides, or in transgenic plants. After activation by intestinal proteases, these toxins interact with receptors, especially cadherin, leading to death due to the formation of cellular pores. In recent years resistant populations have been identified in the laboratory, which can be a problem if the same patterns are found in crops, reducing their control effect. In this paper, we performed a comparative structural analysis of a mutation region for the gene of this receptor in <em>A</em>. <em>gemmatalis</em>, among resistant and susceptible strains treated with a toxin produced by <em>Bt</em> (Cry1Ac). The HaCad fragment of the cadherin gene was amplified by PCR, sequenced, and analyzed by bioinformatics tools. The PCR results were positive for resistant specimens but not for susceptible strains, suggesting the presence of a mutation in the resistant strain. In the sequenced fragments of the resistant insects, six haplotypes were found, and the originated amino acid sequences demonstrated the modification in four sites, which did not interfere with the three-dimensional shape of the protein. These data showed considerable variation taking into account the size of the fragment, even if they do not affect the final structure of the protein. The results allowed a better understanding of the mechanisms of resistance to Cry1Ac in the species, mainly in the involvement of cadherin in this process.</p> Felipe Cordeiro Dias, Jaqueline Fernanda Dionísio, Daniel Ricardo Sosa-Gómez, Renata da Rosa Copyright (c) 2022 Felipe Cordeiro Dias, Jaqueline Fernanda Dionísio, Daniel Ricardo Sosa-Gómez, Renata da Rosa Thu, 28 Apr 2022 00:00:00 +0000 Utilizing Chickpea Isolates as a Fortificant to Develop Protein-Dense Yogurt: A Review <p>Pulses and dairy products are recognized for their nutritional and functional benefits and are consumed in various forms. Yogurt is considered a source of good quality protein with anti-carcinogenic, hypocholesterolemic properties, and palliating effects on lactose intolerance. Similarly, chickpea is known for its high protein content, low glycemic index, and hypoglycaemic effects. These food ingredients cater to numerous advantages for human health and can address public health issues related to malnutrition or other nutritional deficiencies. With this background, the manuscript explores the possibility of employing chickpea isolates to fortify yogurt to improvise protein content along with sensory and physicochemical properties. So far, the literature has shown that protein extracts, when added to yogurt, result in gaining protein content and overall product quality. The yogurt market is growing, and consumers from different countries have expressed their willingness to purchase fortified yogurts to achieve optimum health. Therefore, developing a new combination of yogurt and chickpea isolates can provide a therapeutic alternative to enhance the nutritional status of the vulnerable population, <em>viz</em>. children, pregnant, lactating mothers, elderly, sportsperson, etc., when a judicious food intake is a must.</p> Nikita Arya, Rajendra Kumar Copyright (c) 2022 Nikita Arya, Rajendra Kumar Wed, 20 Jul 2022 00:00:00 +0000 Temporal Variation Analysis of Rice Yield in the Jiangsu Province, China: Application of Decision Support System for Agrotechnology Transfer Model <p>The accuracy of grain yield estimation is critical for national food security. Because of the comprehensive influence of spatial differentiation conditions, such as temperature, precipitation, soil, rice variety, and irrigation, yield estimation requires integrated modeling that is based on dynamic conditions. These dynamic conditions include geographical background, biological factors, and human impact. Most existing studies focus on the observation and analysis of external factors; only a few reports on yield simulations are coupled with nature, management, and crop growth mechanism. Our study incorporates the crop growth mechanism of rice, along with data of rice varieties, soil, meteorology, and field management, to determine the rice yield in Jiangsu province, China. In addition, we have used a decision support system for the agrotechnology transfer model, along with Coupled Model Intercomparison Project data and geographic information system technology. Our results showed that: (1) A calibrated variety genetic coefficient could simulate rice biomass value (flowering stage, maturity stage, and yield) reasonably. The values of NRMSE (Normalized Root Mean Square Error) between the simulated and measured values after parameter calibration are all less than 10%, the values of d(index of agreement) are all close to 1, the simulated value of yield is in good agreement with the measured value. (2) A linear correlation between the meteorological elements and yield was observed. The linear correlation had regional differences. Notably, an increase in precipitation was conducive to the increase in yield. Except at the Huaiyin site, the other sites showed that the temperature rise could potentially lead to reduced production. We found that an increase in solar radiation was unfavorable to the production of rice in the northern and western sites in the Jiangsu province, whereas it was conducive in the southern and eastern sites. (3) Our study predicted the rice yield from typical sites in the Jiangsu province from 2019 to 2060 in the wake of climate change while excluding the extreme effects of diseases, pests, typhoons, and floods. The order of average yield per unit area is as follows: Xinghua site (8212.76 kg/ha) &gt; Huaiyin site (7912.70 kg/ha) &gt; Gaoyou site (7440.98 kg/ha) &gt; Gaochun site (7512.29 kg/ha) &gt; Ganyu site (7460.88 kg/ha) &gt; Yixing site (7167.00 kg/ha). Notably, the average yields from the Xinghua and Huaiyin sites were higher than that from the Jiangsu province (7617.77 kg/ha). The fluctuation of the yield per unit area at each site was generally consistent with the fluctuation in the overall yield, showing a downward trend and tends to be stable. The dispersion of yield per unit area indicates that Gaochun had the most stable yield per unit area followed by Xinghua, Ganyu, Yixing, Huaiyin, and Gaoyou. The yield per unit area of the Huaiyin and Gaoyou sites was unstable and portrayed the biggest fluctuations. Future studies need to focus on how to deal with spatial variation and carry out adaptive verification to make the simulation results applicable to more dimensions.</p> Pan Yuqi, Jiang Penghui, Li Manchun, Chen Dengshuai Copyright (c) 2022 Pan Yuqi, Jiang Penghui, Li Manchun, Chen Dengshuai Fri, 02 Sep 2022 00:00:00 +0000
