    Physicochemical parameters of the Lekki Lagoon in relation to abundance of Wenyonia sp Woodland, 1923 (Cestoda: Caryophyllidae) in Synodontis clarias (Linnaeus, 1758)
    (Environmental Challenges, 2022) Koledoye, T. Y.; Akinsanya, B.; Adekoya, K. O.; Isibor, P. O.
    Parasitic infection of fish is seen worldwide, and they are of particular interest in the tropics. Reports indicate that parasite infections in fishes lead to a disruption in aquaculture production. This study was undertaken to determine the association between physicochemical parameters and the abundance of Wenyonia sp Woodland, 1923 in Synodontis clarias collected from Lekki Lagoon, Lagos, Nigeria. A total of 180 Synodontis clarias were investigated between April 2019 and March 2020. The physicochemical parameters such as temperature, pH, turbidity, electrical conductivity, dissolved oxygen, and total dissolved solids of the surface water at the Lekki Lagoon were assessed in situ using the Horiba U50 multi-water sampler at three (3) Points, 500 metres apart. There was a positive correlation between parasite abundance and all the physicochemical parameters investigated. Water temperature showed a positive correlation with pH and turbidity and a negative correlation with electrical conductivity, dissolved oxygen, and total dissolved solids. The results showed that the statistical T-value (-2.72) of the parasite abundance between the male and the female fish was lower than the critical T-value (1.98), indicating no significant difference in the levels of infections between the male and female fish samples. In conjunction with future data, the data produced in this study can be used in monitoring the aquatic habitat for informed remediation of the lagoon to aid the preservation of the ecological services rendered by the aquatic ecosystem

    In vivo Evaluation of Plant Extracts against Common Phytopathogenic Fungi Isolated from Pawpaw (Carica papaya L.)
    (IOP Conf. Series: Earth and Environmental Science, 2025) Oniha, M. I.; Eni, A. O.; Akinnola, Olayemi O.; Omonigbehin, E. A.; Adegboye, B. E.; Taiwo, O. S.; Odetunmibi, O.A.; Oyejide, S.O.; Aina, M.O.; Isibor, P. O.; Ahuekwe, E.F.
    Plants possess various efficacious natural products to curtailing various problems associated with man and his environment. Fungi cause significant postharvest losses to global pawpaw (Carica papaya) production, particularly in Africa. Current control methods focus primarily on synthetic fungicides that are hazardous to the environment, while plant-based fungicides are characterised with biofriendly and costeffective potential. In this study, three plant extracts were investigated for their in vivo antifungal property opposed to three phytopathogenic mycoflora isolated from Carica papaya post harvest. Aqueous extracts of Moringa oleifera, Telfaira occidentalis and Bauhinia monandra leaves were evaluated at aaglomerations of 150 mg/ml and 75 mg/ml for their antifungal properties in papaya fruits for 7 days. In vivo antifungal evaluation revealed that the three plant extracts showed varying degrees of inhibitory activity against Aspergillus niger, Aspergillus flavus and Rhizopus oryzae. Of the three evaluated plants, B. monandra showed higher antifungal activity during the post-inoculation period. The concentration of 150 mg/ml of aqueous extracts of the plants preserved the fruits and inhibited fungal growth in a range of 3-5 days, while the 75mg/ml concentration of Moringa oleifera, Telfiaria occidentalis and Bauhinia monandria inhibited fungal growth for 3, 2 and 3 days after inoculation, respectively. Significant weight loss was observed in fruits inoculated for both treatments and controls at both concentrations (p-value <0.05). This experimentation has ssubstantiated that the aqueous leaf extracts of M. oleifera, T. occidentalis, and B. monandra possess the potential as natural antifungals for the control and management of fungal diseases
