Studies on the breeding swarms of Anopheles
gambiae complex in malaria control perspective

From Parasite to Prevention: Advances in the understanding of malaria
Edinburgh, UK. 20-22 October 2010
Background
To reduce malaria transmission through vector control,
alternative measures are necessary as transgenic mosqui-
toes are resistant to Plasmodium [1] and sterile insect
technique (SIT) [2]. Both approaches require a fine
understanding of the biology of reproduction of Ano-
pheles gambiae complex. This study aims to characterize
the swarm structure and several environmental para-
meters associated with distribution of breeding swams
and sites in the south of Benin.
Methods
After the survey in field, molecular analyses were done
and productive breeding sites, breeding swarms and
human habitations positions were integrated into a map
using a geographic information system.
Results
The molecular identification of 510 males collected from
17 swarms and 680 females from larvae of An. gambiae
s.l. has allowed the description of breeding swarms and
sites characteristic of two species: An. gambiae M and
An. melas (Figures 1, 2,3) as well as their distribution
(Figures 4, 5). These results indicate that the swarming
and mating system involved mainly mosquitoes of the
same species, suggesting the existence of specific factors
related to the mating system of each species.
Conclusion
Further studies on the swarming and mating system of
An. gambiae s.l. need to be conducted to produce a pre-
dictive model of swarm distribution to aid malaria eradi-
cation strategies based on the use of generalized method
of moments and SIT.
