How Environmental Shifts Can Affect Vector-Borne Illnesses

Publication, Trout Fryxell NewsLeave a comment

                            The publication titled “How Environmental Changes Can Lead to Increased Transmission of Vector-Borne Illnesses,” authored by Associate Professor Rebecca Trout Fryxell in collaboration with Jennifer Richards, an Extension curriculum specialist, Susan Reynolds, a teacher at South Doyle High School, and Lynne Middleton, a State 4-H curriculum specialist, details a MEGA:BITESS lesson plan for middle and high school students. The lesson plan is designed to teach the learner to understand how mosquitoes serve as vectors for transmission of infectious agents causing disease, identity what factors are needed for mosquito oviposition, and observe how changing temperature and precipitation patterns could potentially increase the number of individuals affected by

Community Efforts to Monitor and Manage Aedes Mosquitoes in East Tennessee

Publication, Trout Fryxell NewsLeave a comment

                                  East Tennessee is burdened by mosquito-borne La Crosse virus disease, but minimal resources for mosquito surveillance, management, or related community education exist in the region. To address these needs, we developed a program to train middle and high school educators in basic medical entomology. The educators then used their skills in the classroom to teach students about La Crosse virus disease and conduct mosquito collection experiments. As a case study of a potential application of classroom-collected data, we also partnered with a local non-profit organization to assess the potential for a volunteer litter cleanup to reduce mosquito populations in a Tennessee neighborhood.

Study Reveals High Genetic Diversity, Mutation, and Migration Rates of Bradford Pear

Hadziabdic News, Nowicki News, Publication, Trigiano NewsLeave a comment

  Pyrus calleryana Decne. (Callery pear) is a deciduous tree native to China, Japan, Korea, and Taiwan. It is a popular ornamental tree in the United States (US) with early spring blooms and vibrant fall color. There are at least 26 cultivars of P. calleryana available in the US of which “Bradford” is the most well-known. Open-pollinated P. calleryana escapees are becoming one of the most common invasive tree species in the eastern United States. Developing better management practices for invasive P. calleryana requires detailed knowledge about reproductive biology and genetic diversity of the species, however, little is currently known about genetic variability within those open-pollinated populations. We investigated genetic diversity and population structure of non-cultivated, escaped P. calleryana populations
