Flies are frequent visitors to flowers of many species of plants within the mustard family (Brassicaceae). They derive nutrition from these flowers, and some fly species are pollinators. Field pennycress (Thlaspi arvense) is a mustard species that is being developed as a new “cash cover crop,” i.e., an autumn-sown cover crop whose oil-rich seeds can be harvested profitably in spring. Although pennycress is largely wind- and self-pollinated, its flowers also attract insect visitors. However, the extent of visitation to pennycress flowers by flies remains largely unknown, especially the identities of those flies. Thus, we examined flies associated with …


Insect Floral Visitors Of Red Maple And Tree-Of-Heaven At Potential Risk Of Neonicotinoid Residue Exposure From Spotted Lanternfly Control, Jonathan Elmquist, Kelli Hoover, David Biddinger Feb 2023

Insect Floral Visitors Of Red Maple And Tree-Of-Heaven At Potential Risk Of Neonicotinoid Residue Exposure From Spotted Lanternfly Control, Jonathan Elmquist, Kelli Hoover, David Biddinger

The Great Lakes Entomologist

To manage spotted lanternfly (Lycorma delicatula (White)), an invasive planthopper recently introduced to the United States, governmental agencies, homeowners, and landscape professionals may treat its host plants with systemic neonicotinoid insecticides. Neonicotinoids can be harmful to non-target insect floral visitors collecting pollen or nectar. The insect floral visitors of red maple (Acer rubrum L.) or tree-of-heaven (Ailanthus altissima (Mill.), which are two of the preferred hosts of L. delicatula in Pennsylvania, are often targeted with neonicotinoid applications for control of this pest. To identify the floral visitors of these tree species, we conducted observations and collections of …


Insect Visitors Of Cirsium Pitcheri, A Threatened And Endemic Dune Species, In Relation To Annual Weather Variation, Jordan M. Marshall Jan 2018

Insect Visitors Of Cirsium Pitcheri, A Threatened And Endemic Dune Species, In Relation To Annual Weather Variation, Jordan M. Marshall

The Great Lakes Entomologist

Cirsium pitcheri (Torr. ex Eaton) Torr. & A. Gray (Pitcher’s thistle) is a threatened herbaceous plant endemic to sand dune ecosystems along Lakes Huron, Michigan, and Superior in North America. Habitat for this plant is limited to active dunes with moving sand. I observed floral visitors of C. pitcheri in Indiana Dunes National Lakeshore and Indiana Dunes State Park, and calculated frequency and density of visitor families. Additionally, I tested for relationships between visitor counts and previous growing season mean temperature and precipitation. Formicidae, Anthomyiidae, and Cecidomyiidae were the most frequent families. However, Apidae was the only family correlated with …
