“…Based on assessment by two reviewers, we calculated average P-M scores of 146 for N. cristata and 148.5 for N. peltata (Table 1) out of an available score of 179. P-M scores for each species are similar to those calculated for weeds previously considered to be good candidates for biological control, such as Matricaria perforata (Peschken et al 1988, McClay andDe Clerck-Floate 1999). For introduced Nymphoides, scores would have been higher if they were previous targets of biological control or more was known about natural enemies in the native ranges.…”

This technical note summarizes the results of a scoping study to determine whether the introduced Nymphoides cristata and N. peltata are suitable targets for classical biological control in the United States. A thorough literature review of biology, management, and impacts of both Nymphoides spp. was conducted, and the standard Peschkin-McClay scoring system was applied to assess their suitability as classical biological control targets. Scores from independent reviewers were averaged; 146 for N. cristata and 148.5 for N. peltata. Based on these scores, it was concluded that these Nymphoides spp. are good candidates for biological control. Presented here is the justification for the Peschken-McClay scores and the results of climate-matching studies to determine overseas locations where initial exploration for agents should take place.

“…Such a pattern could appear for species with a high dispersal capacity. The dispersal capacity of the study species is not well known, but studies on a similar species ( Omphalapion hookeri , McClay and De Clerck‐Floate 1999) indicate that dispersal may be fairly limited relative to inter‐patch distances in the study area. An alternative explanation for increased attack rates with increased seed production between years is that the climatic factors favoring seed set in L. vernus are strongly correlated with the factors influencing egg and larval survival of A. opeticum .…”

Fluctuations of resources in time and space will influence not only species abundance but also interactions among species. For plant–consumer interactions, the effects of resource variation have mostly been studied in systems with high resource variability. Systems with moderate variations are less studied, although ecological and evolutionary dynamics of plants and consumers are likely to be affected also by less extreme variability. The effects of variation in a particular resource should depend on consumer diet width. We examined how spatial and temporal variation in seed production in the perennial herb Lathyrus vernus influenced population dynamics and resource utilization in two beetle pre‐dispersal seed predators with different host ranges over six years. The monophagous Apion opeticum occupied fewer patches and had lower densities than the oligophagous Bruchus atomarius. The proportion of seeds attacked increased with increases in seed production between years for both seed predators. A possible explanation for these patterns is that population dynamics of beetles are driven largely by local factors and that the same factors influence both beetle performance and seed production. In B. atomarius, patterns may also be influenced by a more pronounced preference for L. vernus in years with a high seed production in L. vernus. We conclude that relatively modest variation in seed production may result in responses that differ in both direction and extent from those usually observed in systems with high variation in seed production.

“…In Canada, it was subsequently released and is established as a biological control agent against scentless chamomile, Tripleurospermum inodorum (L.) Sch.Bip. (= Matricaria perforata Mérat) (Asteraceae) in British Columbia, Alberta, Saskatchewan, and Manitoba (McClay and De Clerck-Floate 1999). It was also collected on stinking chamomile, Anthemis cotula L. (Asteraceae), in Nova Scotia (Majka et al 2007b).…”

The following species of Curculionoidea are newly recorded from the Canadian province of Quebec: Coelocephalapion emaciipes (Fall, 1898); Ischnopterapion virens (Herbst, 1797); Omphalapion hookerorum (Kirby, 1808); Perapion punctinasum (J.B. Smith, 1884) (all Brentidae); Anthonomus robustulus LeConte, 1876; Pseudanthonomus helvolus (Boheman, 1843); Bagous magister LeConte, 1876; Bagous tanneri O’Brien, 1979; Buchananius striatus (LeConte, 1876); Ceutorhynchus bolteri Dietz, 1896; Ceutorhynchus pallidactylus (Marsham, 1802); Ceutorhynchus pauxillus Dietz, 1896; Conotrachelus buchanani Schoof, 1942; Conotrachelus pusillus LeConte, 1878; Conotrachelus recessus (Casey, 1910); Curculio rubidus (Gyllenhal, 1835); Cylindrocopturus longulus (LeConte, 1876); Hadroplontus litura (Fabricius, 1775); Hypera rumicis (Linnaeus, 1758); Lixus terminalis LeConte, 1876; Myosides seriehispidus Roelofs, 1873; Phloeotribus dentifrons (Blackman, 1921); Plocamus echidna (LeConte, 1876); Scolytus muticus Say, 1824; Sirocalodes sericans (LeConte, 1876); Smicronyx sculpticollis Casey, 1892 (all Curculionidae). Among these, Buchananius striatus, Conotrachelus buchanani, Conotrachelus pusillus, and Curculio rubidus (all Curculionidae) are also recorded from Canada for the first time. The latter is also newly reported from Ontario. Collecting data are provided for Lixus punctinasus LeConte, 1876, previously reported to occur in Canada without any further information, and for Choragus sayi LeConte, 1876 (Anthribidae) and Rhyssomatus aequalis Horn, 1873 (Curculionidae), both previously recorded from Quebec, also without further details.
