The goal of this project was to conduct research and education to increase the availability of insectary plants to enhance beneficial insects in the North-Central Region. In 2015-2016, we conducted weekly sampling of natural enemy and pollinator abundance on 54 species of plants in three common-garden research sites located at: Southwest Michigan Research and Extension Center (SWMREC), the Clarksville Research Center (CRC), and the Northwest Michigan Horticultural Research Center (NWMHRC). Overall, our data show that many native plant species are highly attractive to both pollinators and natural enemies with floral area being the best predictor of attractiveness. Among the species we tested, plants can be selected from early, mid, and late bloom periods to provide continuous resources for pollinators and natural enemies throughout the growing season. Stakeholders were informed of our results through field days, extension presentations, a dedicated website, scientific talks and peer reviewed publications.
- Improved stakeholder knowledge of which insectary plants best support pest-controlling and pollinating insects, especially for use in dry soils.
- Increased access to “best practices” for establishing and maintaining insectary habitats through peer-reviewed research publications, an extension bulletin, annual demonstration field-days at multiple locations, webinars, and website development.
- Improved understanding of the benefits of multi-floral resources for beneficial insects.
- Enhanced land manager skills in utilizing insectary plants to support arthropod-mediated ecosystem services in farmland.
Two graduate students successfully completed their Masters degree’s based on the research they conducted for the project.

We used a combination of field days, talks at extension meetings and commodity Expo events, and workshops to educate stakeholders about our results. We also made our results available through a website on native plants and ecosystem services
Educational & Outreach Activities
Stakeholders were informed about the project results through our 2016 field day which drew 200 participants, multiple extension and scientific presentations, and a workshop held for master gardeners in 2017. An extension bulletin detailing our results is anticipated for summer 2019. In addition, our Native Plants and Ecosystem Services website has been completely redesigned. It now includes a newsfeed articles related to the overall topic of native plants and ecosystem services. A plant selector tool has also been developed and made live on the website. It currently includes plants that we previously tested in other research. Results from our current research will be added to the plant selector tool as they become available. Since January 2015 there were over 340,000 pageviews and the site is currently receiving approximately 200 pageviews per day.
