WEST LAFAYETTE, Ind. —<\/p> \n

Purdue University, Indiana University and the University of Notre Dame have joined the Midwest Center of Excellence for Vector-Borne Diseases<\/a>. The $10 million Midwest center, led by the University of Wisconsin-Madison, is funded for five years<\/a> by the Centers for Disease Control and Prevention<\/a>.<\/p>\n<\/div>\n\n\n

\u201cThe new Indiana partners are fortifying the center\u2019s capacity to advance innovative vector-control approaches for mosquito and tick threats that are unique to the Midwestern environment,\u201d said Lyric Bartholomay, professor of pathobiological sciences at University of Wisconsin-Madison and co-director of the Midwest Center of Excellence for Vector-Borne Diseases. \u201cConnections to these three outstanding universities provide the exciting potential to train Hoosiers to join the battle against vector-borne diseases.\u201d<\/p>\n\n\n\n

The first round of funding for the center in 2017 established a collaboration between universities and public health agencies in Wisconsin, Illinois, Iowa, Michigan and Minnesota. Together they work to better control mosquitoes and ticks \u2014vectors that spread pathogens.<\/p>\n\n\n\n

The academic partners, which will work closely with the Indiana Department of Health, all have industry connections and expertise in vector-control product development. This includes designing, testing and evaluating new insecticides, sprays and devices to control mosquitoes and ticks.<\/p>\n\n\n\n

\u201cWe\u2019re grateful and excited to be included in this second round,\u201d said Catherine Hill<\/a>, professor and interim head of Purdue\u2019s Department of Entomology<\/a> in the College of Agriculture. \u201cUnfortunately, mosquitoes and ticks don\u2019t pay any attention to state borders.\u201d<\/p>\n\n\n\n

All three universities will conduct a series of user-acceptance studies for products designed to control ticks and mosquitoes.<\/p>\n\n\n\n

\u201cHaving buy-in from the stakeholders, particularly for vector control, is critical,\u201d said Molly Duman Scheel<\/a>, the Navari Family Professor of Medical and Molecular Genetics<\/a> at the IU School of Medicine-South Bend. \u201cWhen they feel like they\u2019re part of the technology development process, people embrace it. And if they embrace it, they have more tendency to use it.\u201d<\/p>\n\n\n\n

The project also will provide opportunities for early career scientists. A key goal is to produce the next generation of vector biologists by training students and giving early career scientists new professional opportunities.<\/p>\n\n\n\n

\u201cBecause Indiana is now part of the center, the educational piece is going to be big,\u201d said John Grieco<\/a>, research professor of biological sciences at Notre Dame. \u201cWe\u2019re now included in all discussions around the various vector-related issues in our state. It pulls everybody together as a cohesive unit.\u201d<\/p>\n\n\n\n

Hill\u2019s Purdue team is pursuing minimum-risk plant-derived products for controlling Lyme disease<\/a> and tick pests.<\/p>\n\n\n\n

\u201cTicks are a big problem,\u201d Hill said. \u201cAnd one tick, in particular \u2014 Ixodes scapularis, the Lyme disease tick \u2014 is a vector of Lyme disease and multiple other diseases in the region.\u201d<\/p>\n\n\n\n

The lone star tick<\/a> (Amblyomma americanum) and the dog tick (Dermacentor variabilis) also pose problems for Indiana. And as climate change continues, they pose a potential invasive problem for regions north of Indiana, as well.<\/p>\n\n\n\n

\u201cThe emphasis is going to be on the Lyme disease tick because that\u2019s public enemy No. 1 in North America,\u201d Hill said. But the Asian longhorned tick<\/a> may someday pose a threat. An invasive species first detected in the United States in 2017, it has now become established here. The tick is found in 17 states, including Kentucky, on Indiana\u2019s southern border. If it moves north, it could become a vector of various human-disease pathogens. But the tick also threatens livestock and other animals.<\/p>\n\n\n\n

In her Purdue Extension<\/a> role, Hill receives many queries about how people can control ticks on their properties without using highly toxic, synthetic insecticides. Purdue\u2019s goal of a plant-based product would help. There are permethrin-based or pyrethroid-based neurotoxins available that are reasonably safe for humans, Hill said, \u201cbut I don\u2019t like the thought of putting that in the environment.\u201d<\/p>\n\n\n\n

Scheel\u2019s lab will target Culex mosquitoes, carriers of the West Nile virus<\/a>.<\/p>\n\n\n\n

\u201cWest Nile virus is one of the big impacts on Hoosiers in terms of mosquito-borne illnesses in the United States,\u201d said Scheel, who is also an adjunct associate professor<\/a> of biological sciences at Notre Dame. The virus affects Chicago, too, where her lab will join the center\u2019s ongoing field tests for Culex larvae control.<\/p>\n\n\n\n

Scheel\u2019s lab is modifying yeast to include an environmentally safe, RNA-based pesticide that can be fed to mosquitoes. The yeast is dead when fed to the larvae, which prevents releasing the live microorganisms into the environment. Researchers widely use RNA technology to study gene function. Scheel aims to move the technology from the lab to the field.<\/p>\n\n\n\n

\u201cThe RNA is directed specifically against mosquito genes and not humans or other insects,\u201d she explained. \u201cSome pesticides used broadly across the world are not environmentally friendly or specific to mosquitoes.\u201d<\/p>\n\n\n\n

In recent years, Scheel\u2019s team has conducted extensive public engagement studies on Trinidad in the Caribbean with funding from the U.S. Agency for International Development and the Department of Defense. Her team will begin doing public outreach in the United States, too, with the CDC grant support.<\/p>\n\n\n\n

\u201cWhen we do this stakeholder engagement, we also teach a lot of people about mosquitoes. That\u2019ll be an immediate impact,\u201d Scheel said.<\/p>\n\n\n\n

The lab that Grieco runs with Nicole Achee<\/a>, research professor of biological sciences at Notre Dame, is developing spatial repellants. Unlike topical repellants for the skin, spatial repellents include hanging strips or tabletop devices that create a mosquito-free environment within a certain area.<\/p>\n\n\n\n

\u201cWe\u2019re trying to focus more on the natural products \u2014 botanicals, geranium oils and other extracts \u2014 because those are going to be much more accepted by the U.S. market,\u201d Grieco said.<\/p>\n\n\n\n

Grieco and Achee have tested mosquito control methods to reduce malaria<\/a> and dengue<\/a> in Africa, Asia and Central and South America. Their work has included knowledge, attitudes and practices evaluations of their products among local residents. They envision students in Notre Dame\u2019s Master of Science in Global Health<\/a> program to undertake such evaluations as capstone projects.<\/p>\n\n\n\n

The Notre Dame researchers recently began conducting trials of improved practices (TIPS) to make product improvements. Now they will begin adding lessons learned from the TIPS studies into their U.S. evaluations.<\/p>\n\n\n\n

Once a final product is developed, it must then pass through many U.S. and global regulatory agencies to ensure that it meets environmental safety requirements.<\/p>\n\n\n
