Age of Anopheles gambiae Giles male mosquitoes at time of mating influences female oviposition.
نویسندگان
چکیده
Female Anopheles gambiae were more likely to oviposit when they mated with males that were two days old than when they mated with older males. The females' age at the time of mating and blood feeding did not influence ovipositional patterns. Females were no less likely to oviposit when they mated after blood feeding and maturing eggs. Sperm were present in the seminal vesicles of males 28 hours after eclosion, and their accessory glands were replete by 76-100 hours. The mean life span of sucrose-fed unmated females and males was 22 days.

Daily oviposition patterns of the African malaria mosquito Anopheles gambiae Giles (Diptera: Culicidae) on different types of aqueous substrates
BACKGROUND: Anopheles gambiae Giles is the most important vector of human malaria in sub-Saharan Africa. Knowledge of the factors that influence its daily oviposition pattern is crucial if field interventions targeting gravid females are to be successful. This laboratory study investigated the effect of oviposition substrate and time of blood feeding on daily oviposition patterns of An. gambiae...
متن کاملMating affects egg maturation in Anopheles gambiae Giles (Diptera: Culicidae).
The effect of mating on egg development and the size of the female accessory glands during the gonotrophic cycle of Anopheles gambiae was investigated. Although females that received a measured meal of blood were more likely to produce an egg batch when they were mated, the increased reproduction was not the result of male accessory gland substances. Changes in the size of the female accessory ...
متن کاملEffects of larval competitors and predators on oviposition site selection of Anopheles gambiae sensu stricto.
We examined whether predators and competitors influence selection of oviposition sites by Anopheles gambiae Giles. Mosquitoes in cages laid significantly fewer eggs in rainwater conditioned with a predator (backswimmers, Notonecta sp.) than in unconditioned rainwater. Rainwater conditioned with a putative competitor (tadpoles, Xenopus sp.) also had fewer eggs than unconditioned rainwater. Simil...
متن کاملOvipositional Behavior of Anopheles gambiae Mosquitoes
Mosquito eggs laid within two hours are necessary for transgenic (injection) studies, because mosquito eggs become hard after that period. Thus, in order to have eggs available within this two-hour window, it is important to understand the ovipositional behavior of Anopheles gambiae s.s.. In the present study, the ovipositional behavior of An. gambiae s.s. (Kisumu) was investigated in several d...
متن کاملPre-copula acoustic behaviour of males in the malarial mosquitoes Anopheles coluzzii and Anopheles gambiae s.s. does not contribute to reproductive isolation.
We reveal that males of two members of the Anopheles gambiae s.l. species complex, Anopheles coluzzii and Anopheles gambiae s.s. (hereafter A. gambiae), which are both malaria vectors, perform a stereotypical acoustic behaviour in response to pure tones at frequencies that encompass the frequency range of the female's flight-tones. This behaviour resembles that described for Culex quinquefascia...
