Abstract:
Purpose: This study was carried out to find out the effects of Tarchonanthus Camphoratus (Asteraceae),
Acalypha fruticosa (Fabacea) and Tagetes minuta (Asteraceae) crude extracts on the fecundity of P. duboscqi.
Materials and Methods: The extracts were prepared from the dried aerial parts of T. camphoratus, A. fruticosa,
and T. minuta. Ten female sand flies were aspirated into vials where they were fed on a mixture of the plant
extracts and sucrose solution prepared in a ratio of 1:1.
Results: These crude plant extracts were found to reduce the fecundity of P. duboscqi significantly (P< 0.05). The
extracts were found to reduce the fecundity of P. duboscqi by 73% (A. fruticosa), 53% (T. minuta) and 26% (T.
camphoratus) (P< 0.05).
Conclusion: The higher level of A. fruticosa, T. minuta and T. camphoratus activities would potentially reduce
the population of sand flies. This study has provided proof of the effects of these medicinal plants on the vectorial
capacity of sand flies.
