“…In tests conducted in China and in quarantine in the U.S., R. latipes showed only minor adult feeding on a few Polygonaceae and did not feed at all on any plant species outside the family (Colpetzer et al 2004a;Price et al 2003). There was no egg-laying or larval survival on any host except P. perfoliata.…”

“…In addition, there was a clear indication of loss of apical dominance in the plants with weevils, probably due to the destruction of the terminals by internal larval feeding and adult feeding on capitula (terminal structures associated with flowers or fruits; Colpetzer et al 2004b). Plants with weevils produced many more small side terminals compared with undamaged plants (Hough-Goldstein et al 2008b).…”

“…Once they are full grown, larvae crawl or drop out of the stem and pupate in the soil under the host plant. Adult weevils emerge from the soil about one week later, crawl up nearby stems and mate on the host plant, feed on its leaves, and initiate egg-laying (Colpetzer et al 2004b;Hough-Goldstein et al 2008a;Price et al 2003).…”

“…In the laboratory, females lay between two and four eggs per day, and continue to oviposit at this rate for at least 63 days (Colpetzer et al 2004b), leading to potentially massive population growth under favorable conditions. Adults overwinter in the soil or leaf litter.…”

“…The impact of weevils on P. perfoliata was initially studied using simulated damage based on quarantine observations (Colpetzer et al 2004b) and subsequently in the field with single plants isolated in weevil-proof cages. A 2005 pilot study in the absence of weevils found a highly significant difference in both seed production and plant dry weight depending on sun exposure, with plants in full noonday sun producing more than 2,200 seeds, compared with fewer than 500 per plant for plants in partial sun or full shade (Hough-Goldstein 2008).…”

Status of an ongoing biological control program for the invasive vine, Persicaria perfoliata in eastern North America

Mile-a-minute weed, Persicaria perfoliata (L.) H. Gross (Polygonaceae), an aggressive annual vine native to Asia, has invaded forest edges, light gaps, open fields, and riparian borders in eastern North America. It was accidentally introduced into Pennsylvania in the 1930s and has since expanded its range north to Massachusetts, south to North Carolina, and west to Ohio. A biological control program was initiated in 1996, and in 2004, a permit was issued for release of Rhinoncomimus latipes Korotyaev (Coleoptera: Curculionidae), a host-specific weevil initially collected in China. Since 2004, the biology of the weevil in its introduced range has been studied, along with its impact on P. perfoliata, which can be substantial. Weevils have been released in ten states through 2010, and populations have increased considerably at many sites. Although P. perfoliata continues to expand its North American range, natural and human-assisted dispersal of R. latipes is reducing its negative effects. Here we review and assess the current status of the biological control program.

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.
