Thus the behavioral responses and mortality of Culex quinquefasciatus observed in the present investigation could be attributed to phytochemicals present in the leaf extracts of Cymbopogon citrates.
The findings of the present studies, therefore, suggest the use of Cymbopogon citrates leaf extract as a local resource in controlling mosquito larvae.
The Nigerian plants selected for this study are: Hoslundia opposita, Lantana camara and Cymbopogon citrates with the objectives of determining the antibacterial activities, phytochemical and mineral element composition of leaf extract of the three plants.
Fresh leaves of Hoslundia opposita, Lantana camara and Cymbopogon citrates were collected at different locations in Ado-Ekiti and Ikere Ekiti, Ekiti State, Nigeria.
The results on the investigation of antimicrobial activities of aqueous, methanol and ethyl acetate extracts of leaves of Hoslundia opposita, Lantana camara and Cymbopogon citrates are presented in Tables 1-3.
The aqueous and methanol extracts of Hoslundia opposita, Lantana camara and Cymbopogon citrates when used against some pathogenic organisms such as Klebsiella pneumoniae, Staphylococcus aureus, Streptococcus mutans, Pseudomonas aeruginosa and Escherichia coli showed marked antibacterial activity.
