Lipase and unspecific esterase activity in the fat body of Aedes aegypti L.

Lipid transfer from insect fat body to lipophorin: comparison between a mosquito triacylglycerol-rich lipophorin and a sphinx moth diacylglycerol-rich lipophorin.

Two insect lipoproteins, triacylglycerol-rich Aedes aegypti lipophorin and diacylglycerol-rich Manduca sexta lipophorin, were compared in their ability to load neutral lipid from fat body. When fat body of M. sexta was incubated in vitro with [3H]oleic acid, all radiolabeled fatty acids were esterified, predominantly to triacylglycerol. In A. aegypti fat body, however, half of the label remaine...

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...

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

Spatial distribution and esterase activity in populations of Aedes (Stegomyia) aegypti (Linnaeus) (Diptera: Culicidae) resistant to temephos.

INTRODUCTION The need for studies that describe the resistance patterns in populations of Aedes aegypti (Linnaeus) in function of their region of origin justified this research, which aimed to characterize the resistance to temephos and to obtain information on esterase activity in populations of Aedes aegypti collected in municipalities of the State of Paraíba. METHODS Resistance to temephos...

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 ...
