Enzymatic analysis of uricotelic protein catabolism in the mosquito Aedes aegypti.

Transmission of African Horse-Sickness by Means of Mosquito Bites and Replication of the Virus in Aedes aegypti

Phylogenetic Analysis of Aedes aegypti Based on Mitochondrial ND4 Gene Sequences in Almadinah, Saudi Arabia

Background: Aedes aegypti is the main vector of the yellow fever and dengue virus. This mosquito has become the major indirect cause of morbidity and mortality of the human worldwide. Dengue virus activity has been reported recently in the western areas of Saudi Arabia. There is no vaccine for dengue virus until now, and the control of the disease depends on the control of the vector. Objectiv...

Protein catabolism in mosquitoes: ureotely and uricotely in larval and imaginal Aedes aegypti.

Catabolism of excess dietary protein by Aedes aegypti was investigated during larval development, during and after metamorphosis. Activity profiles were established for xanthine dehydrogenase (XDH, uricotelic pathway) and arginase (ureotelic pathway). Both enzymes are active at all times during the life-cycle. During the aquatic larval and pupal instars, XDH and arginase activities increase wit...

Characterization of dengue virus in Aedes aegypti and Aedes albopictus spp. of mosquitoes: A study in Khyber Pakhtunkhwa, Pakistan

Dengue is a vector-borne disease caused by dengue virus. According to the recent report of CDC that one-third population of the world are at high risk with Dengue fever. The prevalence of the dengue hemorrhagic fever was found more in tropical and sub-tropical regions of the world. Aedes mosquitoes was reported as the main cause of transmission of dengue virus. So the current study was planned ...

Genetic determinants of host ranges of Bacillus sphaericus mosquito larvicidal toxins.

The 51.4-kDa-41.9-kDa binary toxin produced by different strains of Bacillus sphaericus shows differential activity toward Culex quinquefasciatus, Aedes atropalpus, and Aedes aegypti mosquito larvae. The patterns of larvicidal activity toward all three mosquito species and growth retardation in A. aegypti have been shown to be due to the 41.9-kDa protein. By using mutant toxins expressed in Esc...
