The issue of ASEAN food security has led to chemical pesticides-driven policy directives as economic convention for protecting crop yields while concomitantly conferring an implicit ecological and health risk-based ‘trade-off’ that works to undermine SDG target indicators 2.4, 3.9, and 6.3. In this study the Pesticides Consumer-Environmental Indexing System (PCE-ISys), a conceptual heuristic ‘systems-based’ framework is proposed to explore needed policy-informing option(s) beyond the largely cost-externalising rubric of chemical crop protection management, by indexing (the potential for and magnitude of potential) pesticides exposure (EIR-IS) using a semi-quantitative tiered percentile-based, continuous-to-discrete variable transform that captures the stochastic distribution arising from the ‘generalisable’ interconnectivity of political governance, agricultural economy, and natural environment. 1990-2016 indexing results revealed ‘high’ EIR-IS levels for 52% and 63% of Asia-Pacific and ASEAN nations, respectively, with 28% of Asia-Pacific countries scoring at ‘highest’ indexing levels demonstrating pervasive and expansive pesticides-use and/or tonnage contrary to IPM sustainable agricultural practices.

The foraging of honeybees is one of the most well-organized and admirable behaviors that exists among social insects and being greatly influenced by nectarine sources and habitat adaptability. In Bangladesh, apiculture is mostly confined to rearing of European honeybee Apis mellifera L. despite of having the native A. cerana F. due to lack of information about comparative foraging efficiency and productibility of two species in Asian cropland ecosystem. The present study aimed to molecular characterization of two honeybee species in apiary and their foraging performance on litchi orchard. The genetic identity was revealed thorough phylogenetic analysis with >90% bootstrap value using mitochondrial cytochrome oxidase sub unit- 1 (CO1) gene and nucleotide sequence data deposited to NCBI GenBank with accession number ON680900- ON680902 for A. mellifera and ON703291-ON703293 of A. cerana. Upon placing the identified bee hives in litchi orchard, the foraging efficiency were studied based on egression and ingression rate, number of bees visited flowers per minutes, and nectar and pollen collection efficiency in varied time series of the day. Principal component analysis (PCA) for measuring the contribution of different foraging parameters and the species wise PCA biplot revealed the better foraging efficiency by A. mellifera L. compared to A. cerana F. in litchi blooms. However, foraging efficiency of other nectarine sources should be analyzed for suggesting best performing bee species in apiculture.

The culture and growth performance of Spirulina platensis in three different concentrations (25, 50, and 75 percent) of digested rotten mango media (DRMM) and Kosaric medium (KM) as control were investigated. This study intended to examine DRMM as a low cost culture media for microalgae. For 16 days, optical density, cell weight, chlorophyll a concentration, and total biomass of S. platensis under various treatments were measured in every alternate day. The growth rate of S. platensis cultured in the supernatant of DRMM and KM was varied and the maximum cell weight, chlorophyll a content and total biomass of S. platensis were 0.085 mg/L, 0.08 mg/L and 4.824±0.021 mg/L at 50% in DRMM of the culture. This study showed that the growth performance of S. platensis was higher in the supernatant of 50% DRMM than 25 and 75% of DRMM which resulted satisfactorily compared with standard KM. In the supernatant of 50% digested rotten mango medium, large volume spirulina culture may be feasible.

Purpose: This study investigated the suitability of nine common market food wastes in Nigeria for rearing Hermetia illucens. Methods: Substrate suitability was determined through periodic assessment for survival, and measurement of body length, width and weight of H. illucens on each substrate in the laboratory. Results: Survival of H. illucens larvae and pre-pupae on maize flour, cowpea flour, over-ripe banana peels, amaranth leaves, watermelon peels, and bread was comparable to the control substrate (chicken feed). In contrast, survival of larvae to pre-pupae on cabbage and pineapple flesh was significantly lower than on the control. Generally, larvae and adults reared on chicken feed had significantly higher body size and weight compared to those on pineapple flesh or pineapple peels. Conclusion: Due to their inherently high moisture, low protein and low carbohydrate contents, pineapple flesh and pineapple peels are the least suitable substrates for H. illucens survival and growth in the study.

Bangladesh is an agro-based country. Several vegetables and fruits contribute greatly to the national economy. Fruit fly species (Diptera: Tephritidae) have been a serious threat to agriculture in Bangladesh as well as worldwide. Morphological identification sometimes creates misidentification in adult stages, while in eggs, larvae and pupal stages are totally difficult. Nowadays, molecular identification based on DNA barcoding is an effective and rapid identification tool. However, this technique is very limited use in Bangladesh. In this study, adult samples were collected (trapping with ME and CUE) from three different geographic locations (Dhaka, Chittagong and Barisal) of Bangladesh. Adult flies were identified based on DNA barcoding (amplify the sequences with COI gene), and larvae were identified based on species-specific primers. Bactrocera dorsalis (Hendel), Zeugodacus tau (Walker) and Zeugodacus cucurbitae (Coquillett) were identified adult species found in all the locations, whereas B. dorsalis was found in a higher number. In case of host fly identification on the basis of larvae, B. dorsalis was identified from guava in three locations, indicating guava fruit is the suitable host in Bangladesh. Proper management should be taken to control these pest species; otherwise, they will become a great threat to the agriculture of Bangladesh.

Fruits & vegetable commodities incur huge loss in field & postharvest conditions due to infestation by Tephritid Fruit Flies. The adult female flies lay eggs inside near maturity fruits & vegetables. The eggs hatch into apodous larvae which feed on the pulp; making them unfit for human consumption and marketing. Using male pheromone lures like Cue Lure & Methyl Eugenol Lure is one of novel techniques for annihilating male fruit flies only. Female flies can still mate & keep ovipositing fruits. So, an experiment was carried at Maranthana, Pyuthan, Nepal with 3 replications & 7 treatments to devise techniques for female fruit flies management. The experiment comprised of commercially used pheromones like Cue Lure & Methyl Eugenol Lure and 5 home based baits viz. Apple Cider Vinegar, Yeast fermented sugar, Tulsi Lure, Local Liquor Lure & Pumpkin Lure; all poisoned with Malathion, soaked in cotton wick and assembled in Lynfield traps. The experiment was completed in two trappings; 2021/04/18 to 2021/05/09 and 2021/04/16 to 2021/07/07; with similar results in both trappings. The commercial were able to attract the highest number of flies; all of which were male. Local liquor lure & tulsi lure attracted least number of male fruit flies. The Apple Cider Vinegar Lure and Yeast Lure attracted both male & female flies while pumpkin lure attracted only female flies of genus Zeugodacus. Results revealed that female flies of genus Zeugodacus tau & Z. cucurbitae could be attracted efficiently by making use of Apple Cider vinegar and Pumpkin.

A most valuable fungus that has multiple benefits in the agriculture production system. Around the Globe, Framers and scientists have taken the benefit of knowledge on trichoderma use. It is also called as multipurpose fungus because of its use as bio fertilizer as well as biofungicide (Bio agent). Trichoderma is being able to produce volatile compound and ability to solubilize phosphate making them available to plants, it’s used as biofertilizer. As a bioagent it control various pathogens such as Rhizoctonia, Phytophthora, Sclerotinia spp. Presently a large number of Trichoderma based formulations/ Products are available in the global market which are dominated by Trichoderma harzianum & Trichoderma viridae. Its application in developed countries is increasing rapidly replacing the chemical products, while in developing countries still it is lagging behind because of awareness among the peoples. This article is also with purpose to disseminate the awareness among the peoples about its beneficial aspects in crop production process and its contribution in the environment. The main Ambition of this review paper is also to enlight the importance of trichoderma as a biofertilizer and bio agents.

This work was carried out from 15 July 2021 in Grdarasha Field, College of Agricultural Engineering Sciences, Salahaddin University-Erbil. It aims to show the impact of using kenaf fibers as alternative materials in manufacturing. Global climate change and environment pollution cause to do this kind of researching. Kenaf (Hibiscus cannabinus L.) is a fast growing natural crops, belongs to the Malvaceae family. It is an industrial crop has high potential for cultivation in a tropical climate and also which resistance to various soil types and climate. Selecting the raw materials for industrial applications is more important. Actually, kenaf fibers have many advantages to use in wade range of applications, also it’s fibers not just a part of plant useful as raw material but also leaves and seeds have many other advantages and uses. The results show that there is a significant between varieties on growth and fiber yield properties. The highest plant high was of FH952 by (368.33 cm), while the best values of total fresh and dry stem yields were found of HC2 and V36, by almost (219.33 and 60.93 t/ha), respectively. Providing these results through kenaf plant could be considered as substitute materials for timber and other biocomposite manufactures, and also it causes to safe environment by absorption optimal value of carbon dioxide (CO2), then cutting of woodland trees will be decreased. Finally recommended to cultivation fiber crops (kenaf) globally to conserve environment.

This work was carried out from December 2016 to June 2017 in two different regions on the north of Tunisia belong to the Sub-humid bioclimatic stage on Beja and the Semi-arid bioclimatic stage on Oued Mliz. It aims to identify the varieties of chickpea adaptable on each bioclimatic stage and to evaluate the efficiency of water use for some varieties of chickpea. Indeed, analysis of yield parameters such as biological yields, weight of hundred seeds, seeds yield, number of seeds. All varieties were grown in rainfed conditions. For the sub-humid and semi-arid bioclimatic sites plant have received respectively an amount of water of 346 and 261mm. The results show that there is a significant correlation between these parameters. The cultivation of the collection of eight varieties of chickpea in rainfed soil showed an important adaptation to drought. The number of pods marked in Beja1 and Nayer varieties are the highest, because of the ability to fill the pods during the year. While other varieties have a lower number of pods indicating that spring drought could be the cause of high flower abortion, pericarp development and empty pod formation. This research revealed that in the sub-humid bioclimatic stage, all varieties adapt and produce better than on the semi-arid. The semi-arid Tunisian is characterized by the final drought which causes the hydrous stress at chickpea. The conduit of this last in these zones is dependent on the selection of the varieties early and resistant to the water deficit.

The plant pathogens as Alternaria solani, Monilinia fructigena, Botrytis cinereae and Venturia inaequalis cause significant damages on many plants in the European region (particularly in the region of Republic of Bulgaria), especially on orchard cultures which are very important for agricultural industry in this area. There is many existed commercial plant protection products towards this phytopathogens on the market and there is intensive pesticides treatments in order to be overtake infestations and damaging of the plants from this pathogenic fungus. However such king pesticides in the most cases are toxic and harmful for the humans and environment, so there is a need for development and introduction on the pesticide market of the novel environmentally friendly plant protection products against these diseases. In the present research paper an in vitro trials were conducted with ethanol extracts from tarbush plant (Flourensia cernua) with conidial sporulation of of Alternaria solani, Monilinia fructigena, Botrytis cinereae and Venturia inaequalis. The received results show the strong antisporulation action of tarbush plant ethanol extracts towards tested pathogens. However according to the conidiospores of Alternaria solani, there was full lack of effectiveness and even slightly stimulation action of germination of spores. This results can be a base for development of the new natural fungicides against tested plant pathogens wicth can be apllied as in the commersial agriculture, as in the organic or integrated pest management
