The susceptibitity of these populations was assessed by bioassay using DDT (4%), permethrin (1%) and deltamethrin (0.05%). Anopheles gambiae were resistant to both permethrin and DDT in the Sudanian regions but were susceptible in the central and sahelian areas and susceptible to deltamethrin at all sites except Orodara, although mortality values in some populations were close to the resistance threshold. The kdr frequency varied from 0.4 to 0.97 in populations from the Suclanian region and was tower in populations from the Sudano-sahelian and sahelian areas (0.047 to 0.54). Compared to the last survey of kdr in An. gambiae populations conducted in 2000, the kdr frequency did not differ in the S form but had increased in the M form (0.6), with an extended distribution into the Sudano-sahelian region. The frequency of kdr was also found to have increased in An. arabiensis populations (0.28), where it was formerly reported in only a single specimen. These results have practical significance for malaria vector control, programs. specialized Anopheles gambiae Point mutation Pyrethroids DDT Insecticide resistance Burkina Faso 052 103 11 1113-1120 2009 0035-9203 https://www.documentation.ird.fr/hor/fdi:010048408 10.1016/j.trstmh.2009.01.008 0035-9203 [F B010048408] https://www.documentation.ird.fr/hor/fdi:010048408 https://www.documentation.ird.fr/intranet/publi/2009/12/010048408.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2009-12-21 2017-08-23 fdi:010048408 fre
