“…that currently occur in North America have found limited use in ethnobotany and/or gardening (e.g., L. purpurea (L.) Mill. ; see URL Missouri Botanical Garden 2013; also see Saner et al 1995, andVujnovic andWein 1997 for beneficial economic uses of L. vulgaris and L. dalmatica, respectively). With respect to their ecological value in North America, it is suspected to be minimal, although there are reports of Linaria pollination by native bumble bees (De ClerckFloate and Richards 1997).…”

Linaria vulgaris Mill. (Plantaginaceae), common or yellow toadflax, is a Eurasian short-lived perennial forb invasive throughout temperate North America. Rhinusa pilosa (Gyllenhal) (Coleoptera, Curculionidae) is a univoltine shoot-galling weevil found exclusively on L. vulgaris in Europe. Under no-choice test conditions, 13 non-native Linaria species exposed to R. pilosa were accepted for oviposition and most were found to be suitable, to varying degrees, for gall and larval development.

“…Both L. dalmatica and L. vulgaris are self-incompatible (Docherty, 1982;Saner et al, 1995;Vujnovic and Wein, 1997). The frequency of hybridization within the Linaria is thought to be fairly high, although the occurrence of hybridization between L. dalmatica and L. vulgaris has not been recorded (Bruun, 1937;Janko, 1964;Olsson, 1974Olsson, , 1975.…”

“…The steppes of southeastern Europe and southwestern Asia form the native range of Linaria vulgaris (Saner et al, 1995), while L. dalmatica is thought to originate in the Mediterranean region, reportedly from Yugoslavia to Iran (Vujnovic and Wein, 1997). The host race argument has been used to support the petition and subsequent release of host speciWc biotypes of two toadXax agents, Rhinusa antirrhini and Brachypterolus pulicarius, and a number of studies have investigated the possibility that geographically disparate populations of certain toadXax biocontrol species occurring on both L. dalmatica and L. vulgaris may have evolved distinct host races in response to the locally prevalent Linaria species (Groppe, 1992;Harris and Gassmann, 2004;Hering, 2002;Smith, 1959).…”

“…Dalmatian toadXax, Linaria dalmatica (L.) Miller, and yellow toadXax, L. vulgaris (Scrophulariaceae), are shortlived perennial herbs of Eurasian origin (Alex, 1962;Saner et al, 1995;Vujnovic and Wein, 1997). Dalmatian and yellow toadXax are widely distributed throughout North America.…”

“…Dalmatian and yellow toadXax are widely distributed throughout North America. Between the two species, invasive toadXax populations occur in all US states except Hawaii (USDA-NRCS, 2004) and all Canadian provinces (Saner et al, 1995;Vujnovic and Wein, 1997). Three toadXax-feeding insect species are thought to have been adventitiously introduced on horticultural specimens of these weeds: the Xower-feeding beetle, Brachypterolus pulicarius (L.) (Coleoptera: Kateridae), and two seed-capsule feeding weevils, Rhinusa (formerly Gymnetron) antirrhini Paykull, and R. neta Germar (Coleoptera: Curculionidae) (Smith, 1959).…”

Hansen, Richard W.; and Markin, George P., "A retrospective analysis of known and potential risks associated with exotic toadflax-feeding insects" (2005 AbstractTo date, eight exotic toadXax-feeding insect species have been accidentally or intentionally introduced to North America. Reports on their establishment and impact have been recorded for more than 60 years. Environmental risks linked to biological control of toadXax were identiWed in terms of host resources and undesirable impacts on the target species through the critical review of this record. Data gaps revealed during this retrospective analysis are addressed through suggestions for future research and associated experimental methodologies. Known and potential impacts of toadXax-feeding insects on both invasive toadXax and non-target species are examined. Recent programmatic demands for demonstrated agent eYcacy and stringent host selectivity during the prerelease screening process clearly illustrate that classical biological control of invasive toadXax in North America is progressing beyond the so-called lottery approach. 

Soil nitrogen availability and herbivore attack influence the chemical defenses of an invasive plant (Linaria dalmatica; Plantaginaceae)

Chemical defenses are thought to contribute to the invasion success and impacts of many introduced plants; however, for most of these species, little is known about these compounds and how they vary in natural environments. Plant allelochemical concentrations may be affected by a variety of abiotic and biotic factors, including soil nutrients and herbivores. Moreover, such quantitative variation is likely to play an important role in species interactions involving these invasive plants. The purpose of this study was to examine patterns of variation in iridoid glycoside concentrations of the invasive plant Linaria dalmatica (Plantaginaceae). We conducted a greenhouse experiment to investigate the effect of soil nitrogen availability on iridoid glycoside concentrations. Results from this experiment showed that plant iridoid glycoside concentrations decreased with increased nitrogen availability. Additionally, plants were collected from multiple field sites in order to characterize the influence of population, soil nitrogen availability, and herbivore attack on iridoid glycoside variation. Results from field studies indicated that plants demonstrated considerable seasonal variation, as well as variation within and among populations, with iridoid glycoside concentrations ranging from approximately 1 to 15% dry weight. The relationship between soil nitrogen and plant iridoid glycosides varied among populations, with a strong negative correlation in one population, a marginally significant negative relationship in a second population, and no relationship in the remaining two populations. Additionally, we found a negative relationship between iridoid glycoside concentrations and plant injury by an introduced biocontrol agent, the stem-mining weevil Mecinus janthinus (Cucurlionidae). These results show that plant allelochemical concentrations can vary widely in natural environments and suggest that levels of plant defense may be reduced by increased soil nitrogen availability and herbivore attack in this invasive plant species.
