Kwaghe International Journal of Sciences and Technology aims to publish rigorous, peer-reviewed scholarship that advances natural sciences, agriculture, and technology through high-quality quantitative, qualitative, and mixed-methods research. The journal prioritizes methodological transparency, scholarly relevance, and contributions that strengthen scientific knowledge and applied innovation. • Natural Sciences: promote robust research that advances knowledge in core scientific fields and their applications. • Agricultural Development: support scholarship that strengthens agriculture, food systems, environmental sustainability, and rural productivity. • Scientific Methods: welcome research using quantitative, qualitative, or combined approaches, provided the design and analysis are clearly justified. • Technology and Application: encourage work that connects scientific findings to technological innovation, practical implementation, and real-world problem-solving. Submissions should clearly state the research problem, explain the methodological approach transparently, present defensible evidence, and demonstrate a meaningful contribution to science, technology, and/or agriculture. Scope KIJST welcomes articles in natural sciences, agriculture, and related scientific fields. The journal accepts research employing surveys, experiments, content analysis, observation, interviews, focus groups, documentary analysis, and other acceptable approaches, provided the analytic logic is rigorous and clearly reported. • Natural Sciences: physics, biology, chemistry, and related scientific disciplines. • Agriculture: soil science, animal husbandry, crop protection, fisheries, and allied agricultural studies. • Life and Environmental Sciences: ecology, environmental science, biological systems, and applied natural-science research. • Technology and Applied Science: scientific and technological studies with clear practical, industrial, environmental, or agricultural relevance. • Interdisciplinary Research: studies bridging science, agriculture, and technology to address complex societal, environmental, or development-related issues. Priority is given to original research articles that contribute clearly to the body of knowledge, demonstrate appropriate methodological rigor, and offer implications for scientific advancement, agricultural improvement, or technological application.

Abstract

Fish is an affordable source of animal protein and is increasingly utilized to address nutritional deficiencies in tropical regions; however, post-harvest losses caused by insect infestation remain a major challenge to its preservation and utilization. This study aimed to assess the repellent effects of selected biopesticides against adult D. maculatus on smoked fish and to determine their effects on weight loss in smoked fish infested with the pest. Three newly emerged adult insects were introduced into transparent containers containing fish samples admixed with powders of C. annuum, P. guajava leaves, and C. papaya leaves at concentrations of 5.0 g, 7.0 g, and 10 g per 15 ± 5 g of fish. The results showed that the highest mean percentage repellency of adult D. maculatus on smoked catfish was recorded with 10 g of C. annuum powder, yielding 99.92 ± 0.00%, whereas the lowest mean percentage repellency was observed with 5 g of C. papaya powder, with a value of 0.08 ± 0.00%. Overall, C. annuum powder at all tested concentrations demonstrated the greatest repellent effect, while C. papaya showed the lowest repellency among the three plant treatments. The findings further indicated that, for most observation periods, increasing the concentration of plant treatment tended to reduce weight loss in tilapia, although this pattern was not entirely consistent; conversely, weight loss generally increased with longer storage duration at each treatment concentration. The study concludes that the tested biopesticides have potential as alternatives to synthetic pesticides for the control of Dermestes maculatus infestation in smoked fish, with C. annuum showing the greatest promise for enhancing protection and reducing post-harvest losses.
