Authors: Irin Israt Jahan , Biswas Parimal Kanti 
Published: May 2021

An experiment was conducted at Sher-e-bangla Agricultural University during May to July, 2016 to examine the morpho-physical potentiality of eight green manure species and these species are viz. Sesbania aculeata, Sesbania rostrata, Crotalaria juncea, Vigna unguiculata, Vigna mungo, Vigna radiata, Leucaena leucocephala and Mimosa pudica. Leaves number, biomass production and nodulation are an important character of any green manuring crops as these crops are very potential for increasing soil fertility after incorporation. The growth habits of these species were studied from 15 DAS to 45DAS whereas dry matter/plant and nodulation data were taken from 25 DAS to 50DAS. At 45DAS, Sesbania aculeata, Sesbania rostrata and Vigna unguiculata shown 53% to 149% higher plant height compared to Vigna mungo, although C. juncea performed better at 30DAS compared to V. unguiculata. Again, C. juncea along with S. rostrata and S. aculeata gave the highest fresh biomass (24% to 72%), dry biomass (2.6t/ha to 5.25t/ha), dry matter plant-1 (60% to 83%) and nodulation compared to rest green manures at 45DAS whereas V. unguiculata produced higher dry matter plant-1 at 20DAS but later it declined insignificantly at 50DAS.The lowest performance was observed from V. mungo followed by V. radiata and M. pudica. It was shown that S. rostrata, S. aculeata, C. juncea, V. unguiculata and L.leucocephala performed better regarding biomass, dry matter and nodule production.

The main purposes of the study were i) to describe the selected characteristics of the potato farmers; ii). to determine the extent of marketing problems faced by the farmers and iii). to explore relationship between selected characteristics of the farmers and their marketing problems. From the findings it was revealed that about one half of the respondents were middle aged and another half was young (41.9%) and old (8.6%). The highest proportion (73.3%) achieved education ranging from primary to above secondary. Rest of the respondents had no school education. All the respondents had organizational participation. More than two third had medium to high organizational participation. Potato growers of Lohajang were not so much financially sound as the result showed that only (6.7 %) had high capability and the overwhelming majority (58.1% & 35.2%) were under low to medium category. Regarding knowledge, one half of the respondents had low knowledge and the other half had medium to high knowledge. Distance of market place showed not much problems because (81%) of the respondents stayed within 2 km of market place. Among the respondents, the highest (52.4%) proportion had medium storage facilities, while (23.8 %) potato growers had low and high storage facilities. Among the respondents the highest (49.5 %) potato growers faced medium problem in potato marketing. Regarding the relationship between the selected dependent and independent variable, it was observed that age and distance of market place had significant positive relationships with marketing problems of potato growers. Educational level, financial capabilities, extent of use of quality control, availability of marketing information and storage facilities had significant negative relationships with marketing problems of potato growers. On the other hand, organizational participation had no relationship with marketing problems of potato growers.

Published: May 2021

This study was conducted on two chars of Bogura district using primary data and aims at understanding of how flood affects the rural poor living in the char lands. The study revealed that floods have long-term negative implications on socio-economic status. According to survey the most affected sector was agriculture (54.03%), followed by property (28.66%) and health (19.71%), diseases as Diarrhea occurred at alarming levels (76.07%) in the study areas. In the study year food availability and roads communications were also highly affected by flood. Floods make people vulnerable; as they take away their livelihoods at the first instance and leave them with little resources to overcome from the situation. Because of floods, rural poor communities face job loss, and two-thirds of their income is reduced, which limits their capabilities of preparedness, response, and recovery to subsequent floods. People cope with the situation by bearing substantial debts and a loss of productive assets. It also examines the impacts of flood on the livelihood of the rural poor and explores their coping strategies and also observers it as a positive ingredient for fertility and soil improvement. However the present study captures both positive and negative.

Published: May 2021

Any genetic improvement in dairy cattle requires information on productive and reproductive performance in the given population. Animals have been selected to improve their productivity in order to increase the profitability to the farmer. As a result, selection of animals is made for higher production and a shortened productive life. The reproductive performance of Friesian cows under intensive and semi-intensive management system in Bangladesh is poor. Animal selection has historically been based on production traits, and not much attention was given to AI recording. Many attempts were taken scatterly to increase productive and reproductive potential of Bangladeshi cattle for different periods with variable achievements. Therefore, in this review article we have addressed the new tools and information that could be used to determine the level of productive and reproductive performance and to evaluate genetic factors using admixture analysis of cows bred by AI sires which affect reproductive traits of crossbred Friesian dairy cows reared in selected areas in Bangladesh.

Along with other contaminants, bacterial contamination in the dried fishes is a common issue which severely affects the quality of cured fishes. Hence, the present study was aimed to isolate and identify different bacterial flora contaminating different dried fishes, sold at different retail markets within Dhaka Metropolitan city, Dhaka, Bangladesh. A total of 25 different dried fishes were collected from Dhaka North city corporation area (Town Hall kacha bazar, Krishi market, and Mohammadpur kacha bazar) and Dhaka South city corporation area (New market kacha bazar, and Jatrabari chowrasta bazar). Each sample was divided into three regions (head, body, and tail) and bacterial isolation and identification was done by studying their cultural, staining and biochemical properties. Of the 25 dried fishes, Escherichia coli, Bacillus spp., Staphylococcus spp., Salmonella spp. and unidentified bacteria isolation rates were 44%, 56%, 80%, 48%, and 24%, respectively. The presence of E. coli and Salmonella spp. in various dried fish samples could be considered as indication of lack of hygienic condition during dried fish processing. Confirmation through molecular detection methods, pathogenicity, and antibiogram of the isolated bacteria could be included for future study.

Duck plague is an enveloped DNA virus that belongs to the Anatid Herpes Virus; the Herpesviridae family is an acute and highly infectious duck, geese, and swan disease that causes tremendous economic losses of duck rearing in Bangladesh and other duck rearing countries. Therefore, we decided to isolate duck plague virus from recent fields’ outbreaks area and performed molecular detection and phylogenetic analysis to find out the similarities between our findings and other isolates around the world. Visceral organs of 13 suspected ducks from recent outbreaks area were collected by post-mortem examination for inoculum preparation. Several passages were performed to harvest into 9-11 old embryonated eggs Chorioallantoic membrane (CAM) route and duck embryo fibroblast (DEF) primary cell culture. DNA polymerase (446bp) and DNA polymerase (UL, 602bp) genes were used for molecular detection by Polymerase chain reaction (PCR). Pathogenicity was done with duckling and TCID50 on DEF. Molecular characterization was performed from extracted DNA of duckling and 2 Positive PCR products were partially sequenced for phylogenetic analysis of their origin and nucleotide variations. Sequenced data was analyzed to reveal genetic relationships among constructed phylogenetic tree for understanding potential transmission with origin of virus and data was then submitted to gene bank and got accession number for DPV-BR1-MN937272 and DPV-BR-2-MN937273. Among 13 samples, 4(30.77%) were found positive by PCR using DNA polymerase at 446 bp and UL at 602 bp gene. Chorioallantoic membrane (CAM) was observed hemorrhagic after 72 days and duck embryo fibroblast (DEF) become round as showed cytopathic characteristics after 48h of infection .Duckling showed that isolated virus was highly pathogenic as characteristics signs of post-mortem examination. Therefore, this has found that recent isolates have similarity with Bangladesh, India and China isolates. Moreover, TCID50 has confirmed the isolates have accepted titer to be a vaccine strain.

Published: May 2021

This experiment was conducted to determine the optimum level of green tea extract (GTE) in diets without antibiotics and to evaluate its effect on broiler performances. A total of 100 Cob broiler chicks were kept for a period of 5 weeks. Dietary treatments used in this experiment were antibiotic free group (basal diet as a control), GTE 0.5% (basal + GTE 0.5%), GTE 1% (basal + GTE 1%) and GTE 2% (basal + GTE 2%) and antibiotic added group (basal + 0.05% oxytetracycline). GTE supplemented group showed significantly higher body weight and better feed conversion ratio (FCR) than other treatments (P < 0.05) where highest live weight (2034 g/bird) was recorded in broilers group provided with 0.5% GTE. The best FCR (1.58) was observed in the group supplemented with 0.5% GTE. The obtained results also revealed significant (P < 0.05) difference among treatments in the lipid profile parameters (total cholesterol, HDL and triglyceride except LDL). Broilers treated with 0.5% GTE showed lowest total cholesterol (115.0 mg/dl), triglyceride (116.3 mg/dl) and highest HDL (30.75 mg/dl). In conclusion, GTE can be added in the diet @ 0.5% for better growth performances of broiler as an alternative to antibiotic without any negative effect on lipid profile.

Presently, the world is under the toll of pandemic coronavirus disease-2019 (COVID-19) outbreak caused by SARS-CoV-2. Lack of effective and safe therapeutics has stressed the scientific community for developing novel therapeutics capable of alleviating and stopping this pandemic. Within the presented study, molecular docking, ADME properties and all-atom molecular dynamic (MD) simulation, along with two standard antiviral agents (lopinavir and benzopurpurin-4B), were applied to investigate 15 scalaranes sesterterpenes natural compounds, purified from the Red Sea marine sponge Hyrtios erectus, as potential COVID-19 dual-target inhibitors. Following multi-step docking within COVID-19 main protease and Nsp15 endoribonuclease cavities, nine promising drug-like compounds exhibited higher docking scores as well as better interactions with the target’s crucial residues than those of reference ligands. Compounds 2, 6, 11, and 15, were predicted to simultaneously subdue the activity of the two COVID-19 targets. Dynamics behavior of the best-docked molecules, compounds 15 and 6, within COVID-19 target pockets showed substantial stability of ligand-protein complexes as presented via several MD simulation parameters. Furthermore, calculated free-binding energies from MD simulation illustrated significant ligand’s binding affinity towards respective target pockets. All provided findings supported the utility of scalarane-based sesterterpenes, particularly compounds 15 and 6, as promising lead candidates guiding the development of effective therapeutics against SARS-CoV-2.
Tephritid Fruit Fly Semiochemicals: Current Knowledge and Future Perspectives
Authors: Scolari Francesca , Valerio Federica , Benelli Giovanni , Papadopoulos Nikos T. , Vaníčková Lucie 
Published: May 2021

The Dipteran family Tephritidae (true fruit flies) comprises more than 5000 species classified in 500 genera distributed worldwide. Tephritidae include devastating agricultural pests and highly invasive species whose spread is currently facilitated by globalization, international trade and human mobility. The ability to identify and exploit a wide range of host plants for oviposition, as well as effective and diversified reproductive strategies, are among the key features supporting tephritid biological success. Intraspecific communication involves the exchange of a complex set of sensory cues that are species- and sex-specific. Chemical signals, which are standing out in tephritid communication, comprise long-distance pheromones emitted by one or both sexes, cuticular hydrocarbons with limited volatility deposited on the surrounding substrate or on the insect body regulating medium- to short-distance communication, and host-marking compounds deposited on the fruit after oviposition. In this review, the current knowledge on tephritid chemical communication was analysed with a special emphasis on fruit fly pest species belonging to the Anastrepha, Bactrocera, Ceratitis, Rhagoletis and Zeugodacus genera. The multidisciplinary approaches adopted for characterising tephritid semiochemicals, and the real-world applications and challenges for Integrated Pest Management (IPM) and biological control strategies are critically discussed. Future perspectives for targeted research on fruit fly chemical communication are highlighted.
