Abstract/OtherAbstract:
The objective of this study was to evaluate the systemic insecticidal activity of an imidacloprid-treated rodent oral bait, against Phlebotomus papatasi Scopoli, 1786 vector of Leishmania major Yakimoff & Schokhor, 1914 (Kinetoplastida: Trypanosomatidae), etiologic agent of zoonotic cutaneous leishmaniasis (ZCL). Shaw's gerbil Meriones shawi Duvernoy, 1842 (Rodentia, Gerbillidae) were treated with imidacloprid-treated bait (0.05%). In the laboratory, effects on adult and larval of Phlebotomus papatasi fed on treated M. Shawi and on its faeces were studied. The effectiveness of this approach was tested under field conditions. In the laboratory, 100% of P. Papatasi were killed within 24 hours after blood feeding on Meriones shawi treated up to four weeks prior with a single application of imidacloprid (0.05%) bait. In addition, none of the P. Papatasi larvae that consumed feces from M. shawi treated with the imidacloprid bait survived to pupation. In the field, application of the imidacloprid bait resulted in a 90% reduction in the P. Papatasi population up to four weeks prior with a single application of imidacloprid (0.05%) bait. This is the first study to demonstrate field efficacy of insecticidetreated rodent baits for P. papatasi control and the first study to evaluate this approach in M. shawi, a principal ZCL reservoir host. These results suggest that insecticide-treated rodent baits could be used to effectively reduce the populations of P. Papatasi associated with M. shawi in ZCL endemic areas.
