Abstract

Flight activity in strain 16cSS of Anophelesgambiae (sensu stricto) has been investigated using an acoustic actograph. The peak activity was concentrated within the first hour after light off. After recording their activity, individual mosquitoes were examined for their chromosome inversion karyotype. No significant relationship was found of any of the karyotypes to total activity over the 2 hr after light off or the time at which 50% of their activity had been completed.

The results are discussed in relation to the possible widespread introduction of mosquito bed-nets and the possible selection of mosquitoes biting abnormally early before people go to bed.

Résumé

L’activité au vol de l’espèce Anopheles Gambiae (Sensu Stricto) a été étudié grâce à un actographe acoustique. Le pic d’activité se situait pendant la première heure après l’extinction de la lumière. Apres avoir analyser leur activités, les moustiques étaient examinées individuellement pour leur inversion chromosomique. Aucune relation significative fut trouvée entre les karyotypes et l’activité totale plus de deux heures après l’extinction de la lumière ainsi que le temps pendant lequel 50% de l’activité des moustiques a été achevé. Ces résultats ont été discuté en relation avec la possible introduction a large étendue des moustiquaires et la selection des moustiques qui piquent avant que les personnes ne vont dans leur lit.
