Petition for the Release of Aphthona Cyparissiae Against Leafy Spurge in the United States1
Reprinted with permission from: USDA-ARS, March 19, 1986, unpublished. Petition for the release of Aphthona cyparissiae against leafy spurge in the 1 United States ROBERT W. PEMBERTON Part I TO: Dr. R. Bovey, Dept. of Range Science USDA/ARS/SR Texas A&M University College Station, TX 77843 U.S.A. Enclosed are the results of the research on the flea beetle Aphthona cyparissiae (Chrysomelidae). This petition is composed of two parts. The first is the report “Aph- thona cyparissiae (Kock) and A. flava Guill. (Coleopera: Chrysomelidae): Two candi- dates for the biological control of cypress and leafy spurge in North America” by G. Sommer and E. Maw which the Working Group reviewed on Canada’s behalf. Copies of this report should be in the Working Group’s files. This research, which was done at the Commonwealth Institute of Biological Control’s Delémont, Switzerland lab, showed A. cyparissiae to be specific to the genus Euphorbia of the Euphorbiaceae. This result agrees with the literature and field records for A. cyparissiae, which recorded it from: Euphorbia cyparissias, E. esula, E. peplus, E. seguieriana, and E. virgata. The Sommer and Maw report also included information on A. cyparissiae’s taxonomic position, life history, laboratory biology, mortality factors, feeding effects on the host plants, the Harris scoring system, as well as a brief description of the target plant – leafy spurge (Euphorbia esula complex), a serious pest of the rangelands of the Great Plains of North America. Based on this research, the Working Group gave permission to release A. cyparissiae in Canada and to import it into the USDA’s Biological Control of Weeds Quarantine in Al- bany, California, for additional testing. -

Restoration of Semi-Natural Grasslands, a Success for Phytophagous Beetles (Curculionidae)
Biodivers Conserv DOI 10.1007/s10531-016-1217-4 ORIGINAL PAPER Restoration of semi-natural grasslands, a success for phytophagous beetles (Curculionidae) 1,2 1 3 Magdalena Steiner • Erik O¨ ckinger • Gerhard Karrer • 1 1 Marie Winsa • Mats Jonsell Received: 21 October 2015 / Revised: 7 September 2016 / Accepted: 24 September 2016 Ó The Author(s) 2016. This article is published with open access at Springerlink.com Abstract Semi-natural pastures have rich plant and animal communities of high conser- vation value which depend on extensive management. As the area of such land decreases, abandoned semi-natural grasslands have been restored to re-establish biodiversity. Restoration schemes, which include thinning of woody plants and reintroduction of grazing, are mainly designed according to the responses of well-studied groups (such as vascular plants and birds). Weevils (Curculionidae) are a very diverse phytophagous beetle family. Here, we evaluated the restoration success of pastures for weevils (Curculionidae), by comparing their species diversity in abandoned, restored, and continuously grazed semi- natural pastures on 24 sites in central Sweden. Weevils were sampled by sweep-netting. Communicated by Dirk Sven Schmeller.

(Leafy Spurge), on a Native Plant Euphorbia Robusta
Non-target impacts of Aphthona nigriscutis, a biological control agent for Euphorbia esula (leafy spurge), on a native plant Euphorbia robusta John L. Baker, Nancy A.P. Webber and Kim K. Johnson1 Summary Aphthona nigriscutis Foudras, a biological control agent for Euphorbia esula L. (leafy spurge), has been established in Fremont County, Wyoming since 1992. Near one A. nigriscutis release site, a mixed stand of E. esula and a native plant, Euphorbia robusta Engelm., was discovered in 1998. During July of 1999, A. nigriscutis was observed feeding on both E. esula and E. robusta. A total of 31 E. robusta plants were located and marked on about 1.5 ha of land that had an E. esula ground-cover of over 50%. Eighty-seven percent of the E. robusta plants showed adult feeding damage. There was 36% mortality for plants with heavy feeding, 12% mortality for plants with light feeding, and no mortality for plants with no feeding. By August of 2002, the E. esula ground-cover had declined to less than 6% and the E. robusta had increased to 542 plants of which only 14 plants (2.6%) showed any feeding damage. For the four-year period, the E. esula ground-cover was inversely correlated to E. robusta density and posi- tively correlated to A. nigriscutis feeding damage, showing that as E. esula density declines so does Aphthona nigriscutis feeding on E. robusta. Keywords: Aphthona, density, Euphorbia, mortality, non-target impacts. Introduction established populations. These sites were monitored annually to assess the establishment of the bioagents.

Aphthona czwalinae (Weise) INVASIVE SPECIES ATTACKED: Leafy spurge (Euphorbia esula L.) Cypress spurge (E. cyparissias L.) TYPE OF AGENT: Root feeding flea beetle COLLECTABILITY: Not available for general distribution ORIGIN: Hungary DESCRIPTION AND LIFE CYCLE Adult: The black flea beetles measure 2.8 to 3.5 mm long. Their bodies are tapered at the front. Typically the upper portion of their rear legs are black (but can vary to brown), appearing similar to Aphthona lacertosa making them difficult to differentiate. As with all flea beetles, they are capable of jumping great distances and do so readily. Adults usually appear in June and July, but can vary yearly depending on climate. It has been recorded for several years to appear 10 days later than A. lacertosa. The adults tend to congregate for feeding, mating and egg-laying. Females begin to lay eggs one week after emergence. The eggs are laid in clusters of 20 - 30 underground next to a spurge stem. The females seek holes and crevices near plants to deposit their eggs, preferring to keep their ovipositor from contacting the soil. They continue to oviposit every three to five days and produce an average of 250 eggs over the season. The earliest emerging Fig. 1. A. czwalinae adult (credit Powell et al. 1994) adults may have a high mortality rate. Of all the Aphthona species, Aphthona czwalinae has the shortest adult life span, usually about 2- 3 weeks long. Females die shortly after the egg-laying period. Egg: The pale yellow eggs measure 0.7 x 0.4 mm and darken to brown-yellow as they mature. -
