Changes in Abundance of Larvae and Adults ofPopillia japonica(Coleoptera: Scarabaeidae: Rutelinae) and Other White Grub Species in Northwest Arkansas and Their Relation to Regional Temperatures

The Potential Global Distribution and Voltinism of the Japanese Beetle (Coleoptera: Scarabaeidae) Under Current and Future Climates

“…Empirical model projections indicate that the projected 3.5°C increase in temperature across the central United States for 2050 would increase the optimal feeding window for adult beetles by 290% (Niziolek et al 2013). In contrast, Petty et al (2015) found that recent P. japonica population declines in Arkansas were likely due to increasingly hot and dry conditions. Therefore, the increasingly long warm and dry periods projected under future climate scenarios for the southwestern United States (Carter et al 2014) may reduce the plant health threats posed by P. japonica .…”

“…In contrast, increasingly hot and dry conditions projected under the RCP 8.5 reduce previously suitable range in the southeastern United States, southeastern Asia, and all continents in the Southern Hemisphere by midcentury. Given that the southeastern United States is expected to become increasingly warm and dry under climate change (Carter et al 2014) and that recent P. japonica declines in Arkansas have been linked to rising temperatures (Petty et al 2015), it is plausible that this beetle will soon become a minor pest within its current southeastern U.S. range.…”

PM 9/21(1) Popillia japonica: procedures for official control

“…Popillia japonica was first recorded in the United States in 1916 from a nursery near Riverton in New Jersey (Fleming, 1972;Petty et al, 2015). The species is now widespread throughout the eastern States with the exception of Florida (Fleming, 1972;Oklahoma State University, 2010; Oregon Department of Agriculture 2010; University of Florida, 2014).…”
