The extract was tested on <em>Callosobruchus maculatus </em>to evaluate the effects on mortality, oviposition and adult emergence. The extract of <em>E. camaldulensis </em>leaves was effective in controlling <em>C. maculatus </em>as it caused a significantly high mortality of the weevils. Weevil mortality increased with increased in number of days in which they were exposed to the treatments and extract dosage level. Weevil 100% was achieved by 72 h when treated with 3% and 4% dosage level of the exract. The extracts significantly (P &lt; 0.05) caused reduction in oviposition and adult emergence by the weevils. Oviposition and adult emergence decreased with increased in the dosage level of the extract. Oviposition was totally suppressed when insects were exposed to 4% extract dosage level, while there was no adult emergence on exposure to 3 and 4% extract dosage levels. The results obtained from the phytochemical analysis of <em>E. camaldulensis</em> indicated the presence of alkaloids, flavonoids, saponins, tannins, terpenoids, and phenol indicating the quantitative phytochemical composition of phenol to be highest (76.955 mg/100g), followed by alkaloids (33.025mg/100g), flavonoids (11.74 mg/100g), while saponins has the least value of 9.88mg/100g. The GC-MS analysis revealed arrays of bioactive substances that are responsible for the insecticidal and medicinal properties of <em>E. camaldulensis</em>. The leaf of <em>E. camaldulensis</em> is cheap, biodegradable, ecological friendly and very effective bioinsecticides and therapeutic medicine. Hence, can be used as alternative to the poisonous conventional insecticides and drugs.&nbsp;</p> Olusola Michael Obembe , Olumuyiwa Temitope Omotoso Copyright (c) 2024 Obembe and Omotoso; This is an Open Access article distributed under the terms of the Creative Commons Attribution License (http://creativecommons.org/licenses/by/4.0), which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. https://journalajrib.com/index.php/AJRIB/article/view/203 Tue, 02 Jan 2024 00:00:00 +0000 Effect of Different Seed Treatment Methods on the Germination of Senna occidentalis L. 1829 (Coffee Senna) in Sokoto, Sudan Savanna Ecosystem, Nigeria https://journalajrib.com/index.php/AJRIB/article/view/204 <p><strong>Background and Objective: </strong>Seed treatment is an act of subjecting a seed into water, chemical or heating medium often to break its dormancy and enhance its embryo to germinate into a seedling within the shortest time possible. Therefore, seed dormancy has remained the greatest challenging issue in seedling production for any reason in plant production programme the world over. This study was carried out to determine the effect of different seed treatment methods on the germination of <em>Senna occidentalis</em> L. 1829 (Coffee Senna) in Sokoto, Sudan Savanna ecosystem, Nigeria.</p> <p><strong>Materials and Methods: </strong>Hence, three (3) in vitro germination tests at different levels were conducted at Agricultural Chemical Laboratory of the Usmanu Danfodiyo University Sokoto, for thirty six (36) days period to tackle seed dormancy difficulties of <em>S. occidentalis</em>. This was with the view to providing some basic information on the matter due to the socioeconomic nutritional potentials of the plant to man in the Sudano-Sahelian ecosystem.</p> <p><strong>Results: </strong>The study determined 2 days soaking (83.00%), 15 minutes hot water (76.65%) and 10 minutes chemical (H<sub>2</sub>SO<sub>4</sub>) (90.02%) methods as the best germination tests for the seed germinability of <em>S. occidentalis </em>in the study area and the results were reported in percentages. However, the field experiment in turn, revealed that germination percentages of <em>S. occidentalis </em>(Coffee Senna) seeds obtained were 45.78% at Fadama habitat and 35.56% at upland location, respectively.</p> <p><strong>Conclusion: </strong>Therefore, the best methods determined in this study are recommended for practice in the seedling production of <em>Senna occidentalis</em> L. 1829 (Coffee Senna) and its allied species in the study area.</p> Shehu Bello Tsoho, Yusuf Muhammad Sanyinna , Umar Tambari , Armiya’u Muhammad Aminu, Aminu Sanda , Sule Aliyu Anka Copyright (c) 2024 Tsoho et al.; This is an Open Access article distributed under the terms of the Creative Commons Attribution License (http://creativecommons.org/licenses/by/4.0), which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. https://journalajrib.com/index.php/AJRIB/article/view/204 Wed, 03 Jan 2024 00:00:00 +0000 Assessment of Quality of Water from Catchment to Consumers: A Study based on Rahas-Ella Water Purification Plant in Kandy, Sri Lanka https://journalajrib.com/index.php/AJRIB/article/view/205 <p><strong>Introduction:</strong> Rahas-Ella is one of the fascinating waterfalls located in the Wattegama area in Kandy District, Sri Lanka. By receiving raw water from Rahas-Ella, a water purification plant was established in 2013 to provide safe drinking water to the residents in Wattegama municipal area.&nbsp;&nbsp; An investigation was conducted to evaluate several water quality parameters for both raw and purified water, in response to consumer complaints over the quality of drinking water received from this purification plant.</p> <p><strong>Methodology:</strong> Thirteen sampling locations (L01-L13) were identified along the waterfall, from the onsite water purification plant, two wells, and in addition two tap water sources through which the purified water is distributed. Some selected physicochemical and bacteriological parameters were analyzed.</p> <p><strong>Results:</strong> The study revealed that several parameters were higher than the standards concerned for drinking water. Mainly, the turbidity level was high in both the catchment and the intake and this could be a serious health risk to the community.&nbsp; Further, considerably high total counts of both coliforms and <em>Escherichia coli</em> (<em>E. coli</em>) were detected in all samples exceeding the standard values. Although oil and grease were not monitored in this present study, several dwellers reported problems associated with oil pollution.</p> <p><strong>Conclusion:</strong> Based on the observations and results of the study, numerous measures were recommended to improve the water quality of the catchment and to upgrade the treatment facility. The relevant authorities must understand the pathways of microbiological and physicochemical contamination of drinking water and their potential health implications and should carry out necessary steps to improve the quality of water distributed from this purification plant and lessen the negative consequences of improperly purified water on human health.</p> A.

They are not much economically important to humankind as angiosperms; however, they have potential as commercial and environmental resources. Many of them are horticulturally desirable and used for decorations and ornamental purposes. Further, some are used as medicines, food, and fodder, pollution indicators, and for controlling insect pests. During recent decades, much research indicates a decline in the worldwide fern population due to some reasons such as climate change, the use of land for agriculture and other commerce-related uses, predators, invasive species and overexploitation. Under these circumstances, in the present study, the species diversity and richness, distribution, and conservation perspectives of pteridophytic flora in Dunumadalawa forest reserve in Kandy district, Sri Lanka, were investigated using the random sampling method. Every possible area that supports the growth of fern flora in the forest was visited frequently, and representative samples were collected and preserved as herbarium specimens. The species were identified using the “Revised Handbook to the Flora of Ceylon” (Vol. XV and XVI) and verified with the specimens deposited at the National Herbarium, Royal Botanic Gardens, Peradeniya, Sri Lanka. The study found a total of 11 families of pteridophytes from different habitats, consisting of 16 genera and 31 species.</p> Marasinghe L. D. K., Daulagala P. W. H. K. P.
