“…Glucose concentrations were quantified using a modification of the dinitrosalicylic acid method (Lindroth et al 2002a). Levels of the phenolic glycosides salicortin and tremulacin were measured using high performance thin layer chromatography (HPTLC) with purified aspen salicortin and tremulacin used as reference standards (Lindroth et al 1987). Condensed tannin concentrations were quantified using a modification of the butanolHCl method of Porter et al (1986) with purified aspen condensed tannins used as the reference standard.…”

The purpose of this study was to assess the independent and interactive effects of CO(2), O(3), and plant genotype on the foliar quality of a deciduous tree and the performance of a herbivorous insect. Two trembling aspen (Populus tremuloides Michaux) genotypes differing in response to CO(2) and O(3) were grown at the Aspen FACE (Free Air CO(2) Enrichment) site located in northern Wisconsin, USA. Trees were exposed to one of four atmospheric treatments: ambient air (control), elevated carbon dioxide (+CO(2); 560 microl/l), elevated ozone (+O(3); ambient x1.5), and elevated CO(2)+O(3). We measured the effects of CO(2) and O(3) on aspen phytochemistry and on performance of forest tent caterpillar (Malacosoma disstria Hübner) larvae. CO(2) and O(3) treatments influenced foliar quality for both genotypes, with the most notable effects being that elevated CO(2) reduced nitrogen and increased tremulacin levels, whereas elevated O(3) increased early season nitrogen and reduced tremulacin levels, relative to controls. With respect to insects, the +CO(2) treatment had little or no effect on larval performance. Larval performance improved in the +O(3) treatment, but this response was negated by the addition of elevated CO(2) (i.e., +CO(2)+O(3) treatment). We conclude that tent caterpillars will have the greatest impact on aspen under current CO(2) and high O(3) levels, due to increases in insect performance and decreases in tree growth, whereas tent caterpillars will have the least impact on aspen under high CO(2) and low O(3) levels, due to moderate changes in insect performance and increases in tree growth.

“…We used high performance thin layer chromatography (HPTLC) to measure the concentrations of salicortin and tremulacin, the most abundant phenolic glycosides in aspen (Lindroth et al 1987). Leaf samples were extracted in methanol, centrifuged, and 1 ll aliquots were applied in duplicate to HPTLC plates.…”

This study examined the effects of CO and light availability on sapling growth and foliar chemistry, and consequences for insect performance. Quaking aspen (Populus tremuloides Michx.), paper birch (Betula papyrifera Marsh.), and sugar maple (Acer saccharum Marsh.) were grown in controlled environment greenhouses under ambient or elevated CO (38.7 and 69.6 Pa), and low or high light availability (375 and 855 μmol m s). Because CO and light are both required for carbon assimilation, the levels of these two resources are expected to have strong interactive effects on tree growth and secondary metabolism. Results from this study support that prediction, indicating that the relative effect of rising atmospheric CO concentrations on the growth and secondary metabolism of deciduous trees may be dependent on light environment. Trees in ambient CO-low light environments had substantial levels of phytochemicals despite low growth rates; the concept of basal secondary metabolism is proposed to explain allocation to secondary metabolites under growth-limiting conditions. Differences between CO and light effects on the responses of growth and secondary metabolite levels suggest that relative allocation is not dependent solely on the amount of carbon assimilated. The relative growth rates and indices of feeding efficiency for gypsy moth (Lymantria dispar L.) larvae fed foliage from the experimental treatments showed no significant interactive effects of light and CO, although some main effects and many host species interactions were significant. Gypsy moth performance was negatively correlated with CO- and light-induced increases in the phenolic glycoside content of aspen foliage. Insects were not strongly affected, however, by treatment differences in the nutritional and secondary chemical components of birch and maple.

“…exhibit various combinations of constitutive and inducible defenses against phytophagous insects (Philippe and Bohlmann 2007). They involve physical barriers (e.g., trichomes, bark thickness) and chemical defenses (e.g., secondary metabolites such as condensed tannins and salicylate-based glycosides) (Palo 1984, Lindroth et al 1987, Lindroth 2001, Philippe and Bohlmann 2007. Intensity and nature of resistance mechanisms vary according to poplar tissues and damage extent (Palo 1984), and hence directly depend on the insect feeding strategy.…”

Characterization of Antibiosis and Antixenosis to the Woolly Poplar Aphid (Hemiptera: Aphididae) in the Bark of Different Poplar Genotypes

et al. 2013

The woolly poplar aphid, Phloeomyzus passerinii (Signoret) (Hemiptera: Aphididae), is a major pest of poplar plantations in the Mediterranean basin and the Near East. Aphids colonize poplar trunks and feed upon the cortical parenchyma. Despite the economic importance of poplar, little is known about the mechanisms involved in poplar resistance to this pest. However, Populus x canadensis Moench genotypes show various levels of resistance to P. passerinii. This study has investigated the type of poplar resistance (antibiosis or antixenosis) by assessing aphid settlement, physiology (survival, development, and reproduction), and stylet penetration behavior (electrical penetration graph) on three P. x canadensis genotypes; '1214' (susceptible), 'Brenta' (resistant), and '145/51' (intermediate). Because settlement was reduced, the highly resistant genotype Brenta exhibited surface antixenosis. In addition, nymphal survival was null on Brenta, and twice less adult aphid initiated a sustained intracellular phase in the cortical parenchyma of that genotype compared with the other two genotypes. Thus, Brenta also showed parenchyma-located antixenosis coupled with antibiosis characteristic. In contrast, P. passerinii had no difficulty to initiate a sustained ingestion in the cortical parenchyma of the intermediate genotype 145/51, but decreased fecundity and lower intrinsic rate of natural increase were clear expressions of antibiosis.
