Blood-feeding and immunogenic Aedes aegypti saliva proteins.
Mosquito-transmitted pathogens pass through the insect's midgut (MG) and salivary gland (SG). What occurs in these organs in response to a blood meal is poorly understood, but identifying the physiological differences between sugar-fed and blood-fed (BF) mosquitoes could shed light on factors important in pathogens transmission. We compared differential protein expression in the MGs and SGs of ...
متن کاملDifferent Repellents for Aedes aegypti against Blood-Feeding and Oviposition
Methyl N,N-dimethyl anthranilate (MDA), ethyl anthranilate (EA) and butyl anthranilate (BA) were previously shown to repel Aedes aegypti mosquitoes from landing on human skin. However, the effect of these compounds on the orientation of flying mosquitoes in a choice situation and their effect on mosquito oviposition are not yet known. Here, we used a modified Y-tube olfactometer to test the eff...
متن کاملThe Fat Body Transcriptomes of the Yellow Fever Mosquito Aedes aegypti, Pre- and Post- Blood Meal
BACKGROUND The fat body is the main organ of intermediary metabolism in insects and the principal source of hemolymph proteins. As part of our ongoing efforts to understand mosquito fat body physiology and to identify novel targets for insect control, we have conducted a transcriptome analysis of the fat body of Aedes aegypti before and in response to blood feeding. RESULTS We created two fat...
متن کاملEngineering blood meal-activated systemic immunity in the yellow fever mosquito, Aedes aegypti.
Progress in molecular genetics makes possible the development of alternative disease control strategies that target the competence of mosquitoes to transmit pathogens. We tested the regulatory region of the vitellogenin (Vg) gene of Aedes aegypti for its ability to express potential antipathogen factors in transgenic mosquitoes. Hermes-mediated transformation was used to integrate a 2.1-kb Vg-p...
متن کاملFast and slow blood-feeding durations of Aedes aegypti mosquitoes in Trinidad.
The duration of blood feeding by similar-sized Aedes aegypti (L.) was determined under laboratory conditions in Trinidad, West Indies. Ae. aegypti from the F0 generation contained individuals that fed quickly (106.2 seconds) as well as slowly (330.0 seconds). Among the fast feeders (<2 min), the time taken for blood feeding during the first gonotrophic cycle was much shorter than that observed ...
