“…The host-specific weevil, Rhinoncomimus latipes Korotyaev (Coleoptera: Curculionidae), was introduced into North America in 2004 as part of a biological control program targeting P. perfoliata (Colpetzer et al 2004a;Ding et al 2004;Hough-Goldstein et al 2008a, 2009Frye et al 2010). This insect feeds on P. perfoliata leaves as an adult, chewing characteristic small round holes, and its larvae develop internally in P. perfoliata plant stems.…”

Plant populations often exist in spatially heterogeneous environments with varying light levels, which can affect plant growth directly through resource availability or indirectly by altering behavior or success of herbivores. The plant vigor hypothesis predicts that herbivores are more likely to attack vigorously growing plants than those that are suppressed, for example in more shaded conditions. Plant tolerance of herbivory can also vary under contrasting resource availability. Observations suggest that damage by Rhinoncomimus latipes Korotyaev (Coleoptera: Curculionidae), introduced into the United States in 2004 as a biological control agent for mile-a-minute weed (Persicaria perfoliata [L.] H. Gross), is greater in the sun than in shade. We compared weevil densities and plant growth in paired plots in full sun or under shade cloth; a second experiment included insecticide-treated plots in sun and shade, to assess the ability of the plant to compensate for herbivore damage. Greater density of weevils and more node damage (indicating internal larval feeding) were found on P. perfoliata plants growing in sun than on those in shade. Nodes were 14% thicker in the sun, which may have provided better larval habitat. Biomass produced by plants without weevils in the sun was about twice that produced in any other treatment. Herbivory had a greater effect on plant growth in the high-light environment than in the shade, apparently because of movement into the sun and increased feeding there by the monophagous herbivore, R. latipes. Results support the plant vigor hypothesis and suggest that high weevil densities in the sunny habitats favored by P. perfoliata can suppress plant growth, negating the resource advantage to plants growing in the sun.

Quantifying survey completeness is a key step in designing and interpreting biodiversity assessments. To date this has only been examined either at a local scale through repetitive sampling, or across broader geographic areas through multiple survey sites. In this paper, we determine the completeness of sampling at both local and continental scales, of the phytophagous arthropod assemblage on the Neotropical shrub Parkinsonia aculeata (Leguminosae). We used survey gap analysis (SGA) to determine whether existing surveys adequately sampled the diversity of environments and geographic space covered by the plant. Within defined geographic regions, we determined survey completeness at a local scale with species accumulation curves. SGA identified the highest priority sites for future sampling in the Sonoran Desert and the Pacific Coast of South America. The arthropods sampled on P. aculeata differed significantly between seasons, highlighting the importance of including surveys throughout the year. At the local scale, surveys in most regions were estimated to have sampled \50 % of all species. Only the Communicated by Anurag chaurasia. Electronic supplementary materialThe online version of this article (Mexican Gulf, following 84 samples including 902 individuals, had a reasonably complete sample of all species (more than 50 %). As in other studies, rare species will continue to be detected even after extensive surveying, and it is likely that close to 100 samples or 1,000 individuals will be needed to attain 50 % survey completeness in a region. However, if the objective is to document close ''host-associations'' then effort may be better directed at surveying ecologically distinct new areas rather than exhaustive sampling in existing ones. Methods such as SGA can direct such surveys, and in conjunction with species-richness estimates, can be used to assess the adequacy of existing surveys.

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

2011

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.
