Mosquito Knowledgeable from Argentina to Talk about Analysis – Entomology & Nematology Information

Sylvia Fischer of the College of Buenos Aires

Mosquito professional Sylvia Fischer of the College of Buenos Aires, Argentina, will goal the yellow fever mosquito, Aedes aegypti, when she presents a UC Davis Division of Entomology and Nematology’s digital seminar on Wednesday, Jan. 12.

Fischer, a member of the Mosquito Analysis Group, Division of Ecology, Genetics and Evolution, will communicate on “The Latest Enlargement of Aedes aegypti Distribution: Are the Populations Adapting to Colder Local weather Areas?” at 4:10 p.m., Pacific Time. The Zoom hyperlink is https://ucdavis.zoom.us/j/99515291076. 

She can be launched by UC Davis doctoral pupil Erin Taylor Kelly of the laboratory of medical entomologist-geneticist Geoffrey Attardo.  

“The mosquito Aedes aegypti, vector of dengue and different arboviruses, has not too long ago expanded its distribution in the 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 photograph period-induced embryonic diapause as potential mechanisms occurring in temperate Argentina.”

“My major analysis curiosity is on mosquito ecology, and my present challenge goals to research the results of environmental situations (photograph interval, temperature, humidity) and assets (larval meals) on the health of Aedes aegypti,” she writes on ResearchGate. “I’m additionally desirous about human precipitated environmental change and its penalties on vector borne illnesses.”

Fischer not too long ago co-authored a analysis paper on Conduct of Aedes albifasciatus (Diptera: Culicidae) larvae from eggs with totally different dormancy instances and its relationship with parasitism by Strelkovimermis spiculatus (Nematoda: Mermithidae).

Kelly, seminar host, researches the A. aegypti within the Attardo lab. She gained a first-place award on the Entomological Society of America assembly final November along with her poster, “Metabolic Snapshot: Utilizing Metabolomics to Examine Close to-Wild and Colonized Aedes aegypti.” She competed within the Physiology, Biochemistry and Ecology Part.  (See https://bit.ly/3HJR0IF). 

Fischer’s discuss meshes with the work of the Geoffrey Attardo laboratory. In one among his analysis tasks, Attardo investigates 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 comparable to dengue, chikungunya, Zika and yellow fever. Attardo research the prevalence and physiology of insecticide resistance in Californian populations and evaluates using genetic markers to foretell insecticide resistance and to trace motion of genetically unbiased 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 establish compounds that mosquito abatement districts can use for monitoring, and to outline the biochemical pathways required to take care of 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.
