Insecticidal Activities of Plants Extract Against Malaria Vectors in Hadiya Zone, Ethiopia Anmut Assemie, Dasash Mulu, Alemayehu Getahun, Negalign Awoke, Workineh Muluken, et al. Journal of Parasitology Research, 2025 Environmental changes due to global warming and human activities have negatively impacted malaria vector control in Hadiya zone, Ethiopia. Plants contain anthraquinoes. Flavonoids, glycosides, phenol, saponin, steroids, tannin, and terpenes that are target specific, rapidly biodegradable, ecofriendly, and less toxic to human health. The objective of the study was to evaluate the insecticidal activities of Azadirachta indica (neem) and Allium sativum L. (garlic) ethanol extracts against malaria vectors in the study area. Then, 20 g from each (A. indica and A. sativum L.) were extracted separately by ethanol solvents. The phytochemical analysis was evaluated from the crude sample based on standard methods. Then, insecticidal activities were evaluated by introducing the fourth instar larva at 50, 100, 150, 200, and 250 ppm concentrations, and data were subjected to probit analysis to determine the LC50 and chi‐square test to check the significance of the mortality by R statistical software. The presence of phytochemical tests such as alkaloids, saponin, tannin, phenol, anthraquinoes, flavonoids, glycosides, steroids, terpenes, and flavonoids was obtained. The mortality of malaria vectors due to ethanol extract of A. indica and A. sativum was observed. The highest (90.66%) mortality was observed in the ethanol extract of A. sativum at 250 ppm concentration. A. sativum extracts have a significant effect only on the mortality of Anopheles gambiae s.l (X2 = 13.6, p = 0.008687) and Anopheles pharoensis (X2 = 11.002, p = 0.02655), but A. indica have a significant effect only on the mortality of An.pharoensis (X2 = 14.26, p = 0.00651). The lowest LC50 (39 ppm) was observed in the ethanol extract of A. sativum. So, A. sativum extract was highly toxic than A. indica extract and more effective in the reduction of malaria vectors but further studies will be conducted to determine the insecticidal activities at pupa and adult stages.

Plant Growth-Promoting Rhizobacteria Isolated from Degraded Habitat Enhance Drought Tolerance of Acacia (Acacia abyssinica Hochst. Ex benth.) seedlings Alemayehu Getahun, Diriba Muleta, Fassil Assefa, Solomon Kiros International Journal of Microbiology, 2020 Drought stress (DS) is the most impacting global phenomenon affecting the ecological balance of a particular habitat. The search for potential plant growth-promoting rhizobacteria (PGPR) capable of enhancing plant tolerance to drought stress is needed. Thus, this study was initiated to evaluate the effect of inoculating Acacia abyssinica seedlings with PGPR isolated from rhizosphere soil of Ethiopia to enhance DS tolerance. The strains were selected based on in vitro assays associated with tolerance to drought and other beneficial traits such as salinity, acidity, temperature, heavy metal tolerances, biofilm formation, and exopolysaccharide (EPS) production. The strains with the best DS tolerance ability were selected for the greenhouse trials with acacia plants. The results indicate that out of 73 strains, 10 (14%) were completely tolerant to 40% polyethylene glycol. Moreover, 37% of the strains were strong biofilm producers, while 66 (90.41%) were EPS producers with a better production in the medium containing sucrose at 28 ± 2°C and pH 7 ± 0.2. Strains PS-16 and RS-79 showed tolerance to 11% NaCl. All the strains were able to grow in wider ranges of pH (4–10) and temperature (15–45°C) and had high tolerance to heavy metals. The inoculated bacterial strains significantly ( p ≤ 0.05 ) increased root and shoot length and dry biomass of acacia plants. One of the strains identified as P. fluorescens strain FB-49 was outstanding in enhancing DS tolerance compared to the single inoculants and comparable to consortia. Stress-tolerant PGPR could be used to enhance acacia DS tolerance after testing other phytobeneficial traits.
