This impact would be greatly enhanced when sterilization occurs in successive gonotrophic cycles in addition to reduced lifespan as previously shown for An. gambiae s.s. exposed to PPF-treated nets [32]. However, if both species should be targeted by the intervention, more research might be ...
Entry into the salivary gland is important for a majority of pathogens to complete their life cycle [47–49]. Salivary glands secrete various proteins participating in different activities, such as lectins, which are involved in sugar feeding, apyrase which are involved in blood feeding, and D7...
Samples were collected from 4 day old non-blood fed females (NBF), 20 h post-blood meal (PBM) for the first gonadotrophic cycle (PBM1), and 20 h post-blood meal for the second gonadotrophic cycle (PBM2). b Diagram of an ovary and an individual oocyte indicating how yolk ...

Simplified diagram of the model. TheAedes albopictuslife cycle is computed in 7 stages: 3 are aquatic stages present in the breeding sites, eggs (E), larvae (L) and pupae (P), 4 are adult aerial stages, males (M), emerging females (\(F_{em}\)), nulliparous females (\(F_n\)) ...
It is a short-lived organism with a typical life cycle of 15–30 days (Christophers 1960). The reproductive biology of A. aegypti has been well- established. Mating competency typically begins in males that are at least 24-hr old, and mating usually results during male swarming, but also ...
