The impact of co-circulating parasites on West Nile virus transmission
Presenter: Andrew Golnar, Hamer Lab, Dept. of Entomology graduate student
Hosted by TBA

Abstract:

Interspecific interactions between parasites are known to influence population and community epidemiology. Culex mosquitoes ingest a variety of viral, protozoan, and macro-parasitic organisms that circulate among avian and mammalian hosts, however, the epidemiological consequences of mosquito co-infection on vector-borne transmission remains largely unknown. Based on experimental and published data, we built and parameterized multi-host, multi-vector compartmental models to assess how avian malaria may impact West Nile virus transmission dynamics at population and community scales. Transmission heterogeneity due to changes in vector competence, host competence, survivorship, and mosquito feeding habits were evaluated using stochastic simulations and sensitivity analyses employing a Latin Hypercube sampling design. Results highlight the importance of co-circulating parasites as drivers of disease transmission and provide a framework for ongoing transmission experiments.

EEB Seminar Series Fall 2018 – Postdocs

August 28, 2018

Postdoc Talks

“Bridging basic and applied: Saving the world with a fly”

Jonathan Cammack
Decomposition ecology serves as a platform on which one can  decipher the mechanisms regulating nutrient recycling of ephemeral resources. Such an approach provides opportunities for multidisciplinary studies involving fields such as entomology, microbiology, nutrition ecology, and chemical ecology. In addition to providing a greater understanding of the mechanisms that drive the natural process of decomposition, this research has application in addressing global issues of organic waste management and protein shortages. In this talk, I will present on how such basic research is being applied worldwide to help protect the environment, through mass production of the black soldier fly.
“An ecological perspective on triatomine-Trypanosoma cruzi interactions”
Jillian Wormington
Our colony of triatomine bugs, a resource many years in development, presents a unique opportunity to explore understudied aspects of North American triatomine biology, especially those related to transmission of Trypanosoma cruzi, causative agent of Chagas disease. We have found key differences in wing morphology between T. cruzi infected and uninfected triatomines, with implications for human and animal disease risk. Ongoing projects include comparing diel activity patterns in infected and uninfected triatomines, estimating vector competence using experimental infections with local strains of T. cruzi, and indirect xenodiagnosis using domestic dog and non-human primate blood.
