“…However, the flight activity may be also affected by atmospheric factors, such as wind and temperature (e.g., Israd et al, 1999;Bonsignore & Bellamy, 2007). Moreover, it is suggested that there is gene flow between populations of P. nemorum (Nielsen & de Jong, 2005). To better understand the life history of P. nemorum it is necessary to determine how long and frequently P. nemorum individuals actually fly and/or jump.…”

Abstract. Flea beetles are characterized by their tendency to jump. They can also fly. First, the effects of starvation on flight activity in the flea beetle, Phyllotreta nemorum L. (Coleoptera: Chrysomelidae) were determined. After starving P. nemorum for five days a greater number of individuals of both sexes flew than when fed continuously for the same period. In addition, the effect of the mating status of females of P. nemorum on their movement was determined. Mated females were more active than virgin females. It is concluded that starvation stimulates the flight activity of both sexes and mating activates the movement of females of P. nemorum.

“…In Denmark, L. draba is reported as an infrequent host of the flea beetle Phyllotreta nemorum L. (Coleoptera: Chrysomelidae); the frequency of beetles with R genes [resistant to plant defences of alternate host Barbarea vulgaris (L.) W. T. Aiton] was relatively low on L. draba but remained stable over several years, as compared with a very high frequency on B. vulgaris (Nielsen and de Jong 2005). In Iran, the polyphagous beetle Colaphellus hoefti Men.…”

Al-Shehbaz (updated). Can. J. Plant Sci. 88: 379Á401. This paper updates an earlier paper by Mulligan and Findlay (1974) on the cruciferous weeds Lepidium draba, L. chalepense and L. appelianum (treated in the previous paper as Cardaria draba, C. chalepensis and C. pubescens, respectively). Known collectively as hoary cresses, these species reached North America in the 19th and early 20th centuries as contaminants in seed or in ballast. The three species spread extensively in the western parts of the continent by the mid 20th century, partly through seed dissemination, but also by establishment of clonal patches and rhizomatous spread. In the prairie provinces the three species are weeds in grainfields, hayfields and forage crops, and have been largely under control in those crops since the 1970s. By the 1970s all three species had spread into agricultural regions of south central British Columbia and remain a serious problem there. They have also spread into forest, range, and riparian areas of Alberta and British Columbia and are among weedy threats to native ecosystems. Populations in Saskatchewan and Manitoba appear to have stabilized, but remain on noxious weed lists. In the western United States, the species have also spread from cultivated areas into rangelands, and L. draba in particular competes successfully with native vegetation, resulting in reduced local biodiversity. Lepidium draba can also reduce forage production, quality and palatability. Biocontrol measures for L. draba are under investigation. Mechanical controls have proved to be generally ineffective in large populations. Herbicides are effective in the short term in some agricultural crops, but do not provide long-term control, and are of restricted use on rangelands and at riparian sites. Potential beneficial uses of Lepidium draba in phytoremediation and as a source of disease-fighting chemical derivatives are reported. e sie`cle, elles s'e´taient largement disse´mine´es dans la partie ouest du continent, en partie graˆce a`la dispersion des semences, mais aussi par clonage et propagation au moyen de rhizomes. Dans les provinces des Prairies, les trois espe`ces envahissent les champs de ce´re´ales, de foin et de plantes fourrage`res, mais on parvient a`les controˆler dans ces cultures depuis les anne´es 1970.

“…A few examples have been well documented. European populations of Barbarea vulgaris (Brassicaceae) are polymorphic for resistance to a major flea beetle herbivore (Phyllotreta nemorum), and the beetle similarly shows a simply inherited polymorphism for utilization of B. vulgaris (95). Differences in furanocoumarin profiles among populations of human-introduced Pastinaca sativa (wild parsnip) are matched with the detoxification (cytochrome P450) profile of associated populations of the specialist webworm Depressaria pastinacella (96), and the thickness of the exocarp in fruits of Camellia japonica varies clinally in concert with the length of the rostrum of the plant's sole seed predator, the weevil Curculio camelliae (97).…”

Terrestrial biodiversity is dominated by plants and the herbivores that consume them, and they are one of the major conduits of energy flow up to higher trophic levels. Here, we address the processes that have generated the spectacular diversity of flowering plants (>300,000 species) and insect herbivores (likely >1 million species). Long-standing macroevolutionary hypotheses have postulated that reciprocal evolution of adaptations and subsequent bursts of speciation have given rise to much of this biodiversity. We critically evaluate various predictions based on this coevolutionary theory. Phylogenetic reconstruction of ancestral states has revealed evidence for escalation in the potency or variety of plant lineages' chemical defenses; however, escalation of defense has been moderated by tradeoffs and alternative strategies (e.g., tolerance or defense by biotic agents). There is still surprisingly scant evidence that novel defense traits reduce herbivory and that such evolutionary novelty spurs diversification. Consistent with the coevolutionary hypothesis, there is some evidence that diversification of herbivores has lagged behind, but has nevertheless been temporally correlated with that of their host-plant clades, indicating colonization and radiation of insects on diversifying plants. However, there is still limited support for the role of host-plant shifts in insect diversification. Finally, a frontier area of research, and a general conclusion of our review, is that community ecology and the long-term evolutionary history of plant and insect diversification are inexorably intertwined.coevolution ͉ herbivory ͉ insect host range ͉ phylogenetic analyses ͉ plant defense theory
