... time, to our knowledge, the survival, reproduction and infection of Aedes aegypti during vertical and horizontal transmission of dengue virus 2 (DENV-2). Females infected horizontally produced more eggs, with a sex ratio skewed towards males, compared with uninfected controls. However...

... (IgG) targeting the extracellular domain of GluCl from Anopheles gambiae (AgGluCl) on the survivorship of three key mosquito disease vectors: Anopheles gambiae s.s., Aedes aegypti and Culex tarsalis . When administered through a single blood meal, anti-AgGluCl IgG reduced the survivorship...

..., and how different olfactory stimuli are learned by these insects remains unknown. Using a Pavlovian conditioning paradigm, we trained individuals and groups of Aedes aegypti mosquitoes to associate an odorant conditioned stimulus (CS) with a blood-reinforced thermal stimulus (unconditioned stimulus; US...

...Michael P. Kinney; Nicholas D. Panting; Thomas M. Clark The effects of the serotonin-selective reuptake inhibitor paroxetine (2×10 −5 mol l −1 ) on behavior of the larval mosquito Aedes aegypti are described. Four discrete behavioral states dominate larval behavior: wriggling, two distinct types...

... processes linked to V-ATPase activation, but how this is accomplished is still unclear. Here we report that membrane-permeant derivatives of cAMP increase the bafilomycin-sensitive ATPase activity in Malpighian tubules of Aedes aegypti twofold and activate ATP-dependent transport processes. In parallel...

...Teun Dekker; Ring T. Cardé SUMMARY Odours are crucial cues enabling female mosquitoes to orient to prospective hosts. However, their in-flight manoeuvres to host odours are virtually unknown. Here we analyzed in 3-D the video records of female Aedes aegypti mosquitoes flying in a wind tunnel...

...T. M. Clark; J. L. Lawecki; J. J. Shepherd; A. N. Hirschler; T. R. Samandu SUMMARY The role of serotonin in the regulation of larval Aedes aegypti hemolymph composition was investigated in vivo using two reuptake inhibitors (SSRIs), alaproclate HCl and 6-nitroquipazine maleate, and the receptor...

...-genomic biology has been impressively illustrated. Finally we review an integrated physiological approach in Malpighian tubules of the yellow fever mosquito Aedes aegypti which shows that the V-ATPase delivers the energy for both transcellular and paracellular ion transport. * Author...

... transinfected into the primary mosquito vector of dengue virus, Aedes aegypti L. The microbe's ability to shorten lifespan and spread through host populations under the action of cytoplasmic incompatibility means it has the potential to be used as a biocontrol agent to reduce dengue virus transmission...

...Majid Ghaninia; Mattias Larsson; Bill S. Hansson; Rickard Ignell SUMMARY Female Aedes aegypti are vectors of dengue and yellow fever. Odor volatiles are the predominant cues that drive the host-seeking behavior of Ae. aegypti . Odorant molecules are detected and discriminated by olfactory receptor...

...Thomas M. Clark; Marcus A. L. Vieira; Kara L. Huegel; Dawn Flury; Melissa Carper SUMMARY The responses of larval Aedes aegypti to media of pH 4, 7 and 11 provide evidence for pH regulatory strategies. Drinking rates in pH 4 media were elevated 3- to 5-fold above those observed in pH 7 or 11. Total...

...Marjorie L. Patrick; Karlygash Aimanova; Heather R. Sanders; Sarjeet S. Gill SUMMARY This study describes the expression patterns of P-type Na + /K + -ATPase and V-type H + -ATPase in the larval and adult forms of the mosquito Aedes aegypti and provides insight into their relative importance in ion...

.... Treatment of fat bodies with AA uptake inhibitors results in a strong inhibition of AA-induced vg gene expression proving that an active transport mechanism is necessary to transduce the AA signal. We identified two cationic AA transporters (CATs) in the fat body of Aedes aegypti females - Aa slimfast...

...Aparna Telang; Yiping Li; Fernando G. Noriega; Mark R. Brown SUMMARY Reproduction by female mosquitoes is dependent on energy resources but modulated by hormones. Our study focused on blood-meal-dependent, anautogenous Aedes aegypti and autogenous Ochlerotatus atropalpus that rely on larval-derived...

...Geoffrey M. Coast; Christopher S. Garside; Simon G. Webster; Kathleen M. Schegg; David A. Schooley SUMMARY Mosquito natriuretic peptide (MNP), an uncharacterised peptide from the yellow fever mosquito, Aedes aegypti , acts via cyclic AMP to stimulate secretion of Na + -rich urine by opening a Na...

...-released odours. To establish the relative importance and interactions of CO 2 and other body emissions in freely flying mosquitoes, we presented female yellow fever mosquitoes Aedes aegypti L. with broad plumes of human skin odour and CO 2 at natural concentrations and dilutions thereof in a wind tunnel...

...Andrew Donini; Michael J. O'Donnell SUMMARY Ion concentration gradients adjacent to the surface of the anal papillae of larvae of the mosquito Aedes aegypti were measured using self-referencing ion-selective microelectrodes. The gradients were used to calculate estimates of ion fluxes into and out...

...H. Onken; S. B. Moffett; D. F. Moffett SUMMARY The present investigation studied the influence of a number of neuropeptides on semi-open preparations of the isolated and perfused anterior stomach of larval Aedes aegypti . Effects of peptides were observed on the lumen negative transepithelial...
