“…The combination of post‐ and pre‐emergent herbicide applications (in fall 2008 and spring 2009, respectively) essentially negated 2 years of both the mile‐a‐minute and stiltgrass seed banks. However, mile‐a‐minute seeds can be viable for up to 6 years (Hough‐Goldstein et al 2008 a ) and Japanese stiltgrass seed can persist for at least 3 years (Barden ). Thus, both weeds have the capability to reinvade, and in fact stiltgrass reinvaded the herbicide control plots at Crosslands and Waterloo Mills during 2010, but was unable to establish large populations in the revegetated herbicide plots.…”

“…Here, we studied management techniques for an invasive species, mile‐a‐minute weed ( Persicaria perfoliata ), with a broader goal of restoring native plant communities. Persicaria perfoliata is a spiny annual vine of Asian origin that established in York County, Pennsylvania, in the 1930s (Moul ) and has since invaded 13 states in the eastern United States (Hough‐Goldstein et al 2008 a , 2012). Mile‐a‐minute weed can form dense monocultures and outcompete native plants in a variety of habitats and thus poses a threat to natural ecosystems (Mountain ; Hough‐Goldstein et al 2008 a ).…”

Efforts to suppress an invasive weed are often undertaken with the goal of facilitating the recovery of a diverse native plant community. In some cases, however, reduction in the abundance of the target weed results in an increase in other exotic weeds. Mile‐a‐minute weed (Persicaria perfoliata (L.) H. Gross (Polygonaceae)) is an annual vine from Asia that has invaded the eastern United States, where it can form dense monocultures. The host‐specific Asian weevil Rhinoncomimus latipes Korotyaev (Coleoptera: Curculionidae) was first released in the United States in 2004 as part of a classical biological control program. At three sites invaded by mile‐a‐minute weed, biological control was integrated with pre‐emergent herbicide use and two densities of native plantings. After 2 years, native plant cover differed significantly and was greater than 80% in the plots with plantings and pre‐emergent herbicide but less than 30% in the planting treatments without herbicide. Where mile‐a‐minute cover decreased at the two sites with the greatest pressure from exotic plants, plots were dominated by another exotic weed, Microstegium vimineum (Trin.) A. Camus, Japanese stiltgrass. The combination of biocontrol, pre‐emergent herbicide, and revegetation with native plants suppressed mile‐a‐minute weed, prevented invasion by Japanese stiltgrass, and increased the abundance of native plants. The selection of the management strategies used to control mile‐a‐minute weed determined the extent of recovery of the native plant community.

“…P. perfoliata was introduced into eastern North America in the mid to late 1930s (Moul, 1948) and thus has had approximately 70 years (= 70 generations) to adapt to its new environment. The plant showed a typical lag period up until about 1980, during which time it expanded its population slowly, but during the past several decades its population in North America has greatly expanded (Price et al , 2003; Kumar & DiTommaso, 2005; Hough‐Goldstein et al , 2008a). In North America the plant often develops extensive monocultures and suppresses local vegetation (Wu et al , 2002; Kumar & DiTommaso, 2005; Hough‐Goldstein et al , 2008a).…”

Increased reproductive capacity and physical defense but decreased tannin content in an invasive plant

Plant invasions create novel plant-insect interactions. The EICA (evolution of increased competitive ability) hypothesis proposes that invasive plants will reallocate resources from defense to growth and/or reproduction because they have escaped from their co-evolved insect natural enemies. Testing multiple herbivory by monophagous and oligophagous herbivores and simultaneous measurement of various plant traits will provide new insights into the evolutionary change of invasive plants. In this context, we conducted a common garden experiment to compare plant growth and reproduction, chemical and physical defense, and plant responses to herbivory by different types of herbivores between invasive North American populations and native East Asian populations of mile-a-minute weed, Persicaria perfoliata. We found that invasive mile-a-minute exhibited lower biomass, flowered earlier and had greater reproductive output than plants from the native range. Compared with native populations, plants from invasive populations had lower tannin content, but exhibited higher prickle density on nodes and leaves. Thus our results partially support the EICA hypothesis. When exposed to the monophagous insect, Rhinoncomimus latipes and the oligophagous insects, Gallerucida grisescens and Smaragdina nigrifrons, more damage by herbivory was found on invasive plants than on natives. R. latipes, G. grisescens and S. nigrifrons had strong, moderate and weak impacts on the growth and reproduction of mile-a-minute, respectively. The results indicate that mile-a-minute may have evolved a higher reproductive capacity in the introduced range, and this along with a lack of oligophagous and monophagous herbivores in the new range may have contributed to its invasiveness in North America.

“…A single P. perfoliata can produce thousands of seeds that can survive for up to 6 years in the seed bank . Because seeds are dispersed by birds, deer, vehicular traffic, and water, it is hard to predict the direction, distance, and extent of weed spread in the landscape. These characteristics make P. perfoliata a serious weed of tree plantations, orchards, natural forests and wildlife habitats .…”

BACKGROUND: Rhinoncomimus latipes (Coleoptera: Curculionidae) is a major biological control agent against the invasive plant Persicaria perfoliata. Release of R. latipes is challenging with the current visit-and-hand release approach because P. perfoliata shows a high degree of patchiness in the landscape, possesses recurved barbs on its stems, and often spreads into hard-to-access areas. This 3-year study developed and evaluated unmanned aerial systems (UAS) for precise aerial release of R. latipes to control P. perfoliata. RESULTS:We have developed two UAS (i.e. quad-rotor and tri-rotor) and an aerial release system to disseminate R. latipes. These include pods containing R. latipes and a dispenser to accommodate eight pods. Results of field tests to evaluate the systems showed no significant (P > 0.05) effects on survivorship and feeding ability of R. latipes after aerial release. CONCLUSION: Our study demonstrates the potential of UAS for precision aerial release of biological control agents to control invasive plants. The aerial deployment systems we have developed, including both pods and a dispenser, are low cost, logistically practical, and effective with no negative effects on aerially released R. latipes.
