Sylvia Fischer of the College of Brazil
Mosquito knowledgeable Sylvia Fischer of the Mosquito Research Group, College of Buenos Aires, will current the UC Davis Division of Entomology and Nematology’s digital seminar on Wednesday, Jan. 12 on “The Current Growth of Aedes aegypti Distribution: Are the Populations Adapting to Colder Local weather Areas?”
Her seminar, open to all individuals, begins at 4:10 p.m., Pacific Time. She will likely be launched by UC Davis doctoral candidate Erin Taylor Kelly of the laboratory of medical entomologist-geneticist Geoffrey Attardo. The Zoom hyperlink is https://ucdavis.zoom.us/j/99515291076.
“The mosquito Aedes aegypti, vector of dengue and different arboviruses, has just lately expanded its distribution in direction of colder local weather areas,” Fischer says in her summary. “This could be favored by an adaptation of the populations to native situations. We discover the larval tolerance to low temperatures and the photoperiod induced embryonic diapause as potential mechanisms occurring in temperate Argentina.”
A. aegypti is also called the yellow fever mosquito. Kelly, the host, research the mosquito within the Attardo lab. She gained a first-place award on the Entomological Society of America assembly final November together with her poster, “Metabolic Snapshot: Utilizing Metabolomics to Evaluate Close to-Wild and Colonized Aedes aegypti.” She competed within the Physiology, Biochemistry and Ecology Part. (See https://bit.ly/3HJR0IF).
Fischer’s speak meshes with the work of the Geoffrey Attardo laboratory. In one in all his analysis initiatives, Attardo works on the specter of these invasive mosquitoes, which have gained a foothold and unfold all through the state, placing California in danger for Aedes-vectored illnesses akin to dengue, chikungunya, Zika and yellow fever. Attardo research the prevalence and physiology of insecticide resistance in Californian populations and evaluates the usage of genetic markers to foretell insecticide resistance and to trace motion of genetically impartial populations of aegypti all through the state. Attardo and his lab are additionally at the moment growing novel biochemically oriented strategies of insecticide resistance quantification to determine compounds that mosquito abatement districts can use for monitoring, and to outline the biochemical pathways required to keep up this problematic adaptation.
The division’s weekly seminars, held at 4:10 p.m. on Wednesdays, are coordinated by nematologist Shahid Siddique, who could also be emailed at ssiddique@ucdavis.edu with any technical questions.
