    Notes: Abstract The effects of aluminium (Al), manganese (Mn), zinc (Zn), copper (Cu), boron (B), iron (Fe), gallium (Ga), scandium (Sc) and lanthanum (La) on growth of an Al-tolerant and an Al-sensitive line of wheat (Triticum aestivum L.) were measured in solution culture. The concentrations of nutrients in the basal nutrient solution were (μM) 500 Ca, 100 Mg, 300 K, 600 N (150 NH4, 450 NO3), 600 SO4, 2.5 P, 3 B, 2.5 Fe, 0.5 Zn, 0.5 Mn, 0.1 Cu at a pH of 4.7. The major solution nutrient concentrations were maintained at the nominal concentration with monitoring, frequent additions and weekly renewal. Differentiation in yield between the Al-tolerant and Al-sensitive line only occurred in the presence of Al indicating that, in the long term, none of the other metals tested could be used as an analog for Al. The visual symptoms in the roots of Cu toxicity (in both lines) and Al toxicity (in the sensitive line) were similar. The solution concentration (μM) at which yield of the roots of the tolerant line was reduced by 50% was, in order of increasing tolerance, Cu 0.5, Sc 1.1, La 7.1, Ga 8.6, Al 15, Zn 19, Fe 84, B 490 and Mn 600.

    Notes: Abstract In a field-trapping experiment, western balsam bark beetles,Dryocoetes confusus Swaine, were highly attracted to a 5∶1 mixture of (±)-exo-and (±)-endo-brevicomin. Beetles in the sympatric speciesD. affaber (Mann.), were best attracted to a 1∶1 blend of these semiochemicals [either (±)∶(±) or (±)∶(±)], suggesting that both geometrical isomers are pheromone components in these species. In laboratory bioassays and further field experiments, attraction ofD. confusus was greatest when the (+) enantiomers of both geometrical isomers of brevicomin were presented in a 9∶1 ratio. Responses by maleD. confusus to attractive mixtures were reduced in the presence of (−)-exo-brevicomin. Exploitation of the complete range of variability in pheromone structure (both geometrical and optical isomerism) would allow for optimization and regulation of response levels within a species and also could maintain reproductive isolation among sympatric congeneric species primarily through production and response to species-specific blends.

    Notes: Abstract In addition totrans-3,7-dimethyl-6-octen-4-olide (eldanolide), vanillin, and 4-hydroxybenzaldehyde, identified by French workers in the wing gland and abdominal hair pencil secretions of the male African sugarcane borer,Eldana saccharina, we have, in an earlier note, reported the presence of several other terpenoid, aromatic, and unbranched-chain compounds such as, (Z)-3,7-dimethylocta-2,6-dienoic acid, 6,10,14-trimethyl-2-pentadecanol, 4-hydroxy-3-methoxybenzyl alcohol, 1-octadecane thiol, 16-hexadecanolide, and 18-octadecanolide in these secretions. In the present paper experimental details and spectral evidence supporting the identification of these compounds, as well as the identification of (Z)-9-hexadecenal and cw-3,7-di-methyl-6-octen-4-olide (cis-eldanolide), are reported. Using electroantennography it was found that male and female antennae reacted approximately equally strongly to both secretions. This result was confirmed in analyses of the secretions using coupled gas chromatography-electroantennography and it was found that male as well as female antennae responded to eldanolide. Vanillin, substituted phenols related to vanillin, and some oxygenated monoterpenes elicited weak responses in male and female antennae. In some analyses 6,10,14-trimethyl-2-pentadecanol, present in the secretions of the insect, gave a strong antennal response. The results obtained in dynamic and static headspace determinations showed that several of the organic compounds present in the glandular secretions are released in detectable quantities and are present in widely varying quantitative ratios in the effluvia of individual calling male moths.

    Notes: Abstract Electroantennogram profiles of saturated and monounsaturated 12-, 14-, and 16-carbon acetates, and 12- and 14-carbon alcohols implicated (Z)-9-tetradecen-1-ol acetate (Z9-14: Ac) as a component of the female sex pheromone ofHulstia undulatella (Clemens). Gas chromatography-mass spectrometric analysis of extract of the female sex pheromone glands showed the presence of Z9-14:Ac (8.5 ng/female), (Z)-9-tetradecen-1-ol (Z9-14:OH), and (Z)-11-hexadecen-1-ol acetate (Z11-16:Ac) in a ratio of 100∶4∶21, respectively. In tests in sugar beet fields, Z9-14:Ac alone produced some trap catch. Addition of Z9-14: OH did not increase catch while addition of Z11-16:Ac eliminated catch, but addition of both Z9-14:OH and Z11-16: Ac increased catch sevenfold. A combination of Z9-14: OH and Z11-16: Ac without Z9-14: Ac did not produce trap catch. A lure of 200 μg Z9-14:Ac+16 μg Z9-14:OH+42 μg Z11-16:Ac is suggested for use in monitoring traps.

    Topics: Biology
    Notes: Abstract Polyethylene dispensers (Shin Etsu) containing 172 ml of the sex pheromone, (E, E)-8,10-dodecadien-1-ol (63%), dodecenol (31%) and tetradecenol (6%), of codling moth (CM),Cydia pomonella (L.), were placed in apple orchards in Virginia. Two blocks of about 2 ha each were treated in 1989, and three in 1990. Dispensers were placed in trees at a density of 1000/ha shortly after apple bloom. Male orientation to pheromone traps was almost totally disrupted (a few males were captured at high population densities). In 1989, the Daleville pheromone-treated block had 0.9% and 0.8% CM-injured fruit in the center and edge, respectively; 0% and 39.5% injured fruit were found in the conventional control and abandoned blocks, respectively. The Criglersville orchard (‘organically’ managed, with high CM density) CM harvest injury was 16.0%, 16.5%, 34.5%, and 26.5% in the pheromone-treated center and edge, organic control and abandoned blocks, respectively. In 1990, the Daleville CM harvest injury was 4.7%, 7.3%, 1.1%, 0.3% and 58%, in the pheromone-treated center and edge, control center and edge, and abandoned blocks, respectively (possible reasons for the high injury in this block are discussed). Harvest injury in the Fincastle pheromone-treated and control blocks were 0.7% and 0%, respectively. The Criglersville orchard yielded 17%, 19% and 20% CM-injured fruit at harvest in the pheromone-treated, organic control and abandoned blocks, respectively. Pheromone release rate was calculated as 37 mg/ha/h in 1989.

    Notes: Abstract Mating disruption for control of variegated leafroller (VLR),Platynota flavedana (Clemens), tufted apple bud moth (TBM),P. ideausalis Walker, and redbanded leafroller (RBL),Argyrotaenia velutinana (Walker), was studied in Virginia apple orchards in 1989 and 1990. In 1989, each dispenser (1000/ha) contained 190 mg of 67.2%E11–14:Ac, 28.8%Z11–14:Ac, 1.4%E11–14:OH, 0.6%Z11–14:OH, and 2%Z9–12:Ac (a putative generic leafroller disruption blend). Trap captures of VLR, TBM and RBL were reduced by 97%, 51% and 55%, respectively. Average leafroller injury in the interior and edge of the pheromone block was 3.8% and 2.7%, respectively. The conventional control and abandoned blocks had 0.05 and 27.5% injury, respectively. Dispensers containingE11–14:OH (70%) andZ11–14:OH (30%) (close to the natural blend of VLR), more effectively disrupted orientation to pheromone traps by bothPlatynota spp. than did the generic blend. In 1990, dispensers containing 150 mg ofE11–14:OH (70%) andZ11–14:OH (1000/ha) were placed in two 2-ha blocks and one 4-ha block. One pheromonetreated block was sprayed in August with phosmet for codling moth, not timed for leafrollers. Trap captures of VLR and TBM were reduced by almost 100% and 69%, respectively. RBL captures were not reduced by VLR pheromone permeation. Injury fromPlatynota spp. in pheromone block middles and edges ranged from 0.3–1.7% and 0.3–2.3%, respectively. Injury in conventional blocks ranged from 0–1.1%. RBL injury in pheromone block middles ranged from 0–6.1%, and in edges, 1.7–4.8%. Injury in control blocks ranged from 0–1.1%. Combined leafroller injury in an abandoned block was 18% (s.e. 0.3). Release rates averaged 30 and 32 mg/ha/h for the VLR and generic pheromone dispensers, respectively.

    Notes: Abstract Oviposition of four tortricid pests of vineyards (the European grapevine moth and the grape berry moth) and fruit orchards (the codling moth and the oriental fruit moth) is deterred by a blend of straight chain fatty acids and esters of fatty acids that have been identified in the eggs of one of them: the European grapevine moth (EGVM)Lobesia botrana. This is the first evidence of inter-specific recognition of an egg-like signal in moths. We demonstrate that oviposition site selection is influenced by population density, avoidance of deterrent being most important when females are isolated. Inter-specific egg recognition might be an important phenomenon, especially in species competing for a common food resource. We propose the term ‘oviposition regulating synomone’ for molecules and blends that affect the inter-specific spacing of eggs.

    Notes: Abstract The activity ofArchips cerasivoranus caterpillars is largely limited to their colonial silk web and trails. Silk pulled directly from the spinnerets of caterpillars and wound onto paper strips to form artificial trails elicited locomotion from the larvae. Trails made from extracts of silk and silk glands also elicited locomotion. These and other observations reported here indicate that the caterpillars are responsive to a water-soluble pheromone that is a component of the silk strand. Marker pheromones appear not to be secreted from other regions of the body, as has been reported for some other trail-following caterpillars.

    Topics: Biology
    Notes: Summary Thinopyrum bessarabicum (2n = 2x = 14, JJ) with its unique property of salt tolerance provides a potential means for the transfer of this important and complex trait into cultivated wheat through intergeneric hybridization. To accomplish this, diagnostic markers for detecting the presence of Th. bessarabicum chromosomes in a wheat background have to be established. The C-banded karyotype of Th. bessarabicum distinctly identifies individual Th. bessarabicum chromosomes and separates them from those of Triticum aestivum. Also, seven protein/isozymes, i.e., malate dehydrogenase, high-molecular-weight glutenin, Superoxide dismutase, grain esterase, glutamate oxaloacetate transaminase, β-amylase and α-amylase, were identified as being positive markers specific to Th. bessarabicum; these were also expressed in the T. aestivum/Th. bessarabicum amphiploid. These diagnostic biochemical markers could be useful in detecting and establishing homoeology of Th. bessarabicum chromosomes in T. aestivum/Th. bessarabicum intergeneric hybrid derivatives.

    Manganese nutrition and accumulation of phenolics and lignin as related to differential resistance of wheat genotypes to the take-all fungus (1993)

    Notes: Abstract Differential resistance of four Triticum aestivum L. genotypes to isolates of take-all fungus (Gaeuman-nomyces graminis var. ritici Walker) was tested in a complete factorial experiment set up in a growth chamber using Mn-deficient Wangary sand amended with four rates of Mn. Mn-efficient cultivars produced more dry matter at low supply of Mn. Fertilization with Mn significantly increased its accumulation in roots and shoots. The most sensitive measure of take-all infection was the total length of root stellar lesions; these lesions were reduced by Mn fertilization and were shorter in Mn-efficient genotypes. The resistance-enhancing effect of Mn was the most obvious in the Mn-inefficient genotype (Bayonet) and the least obvious in the Mn-efficient one (C8MM). Phenolics biosynthesis in roots was clicited by fungal infection, especially in the case of the highly virulent isolate. The weakly virulent isolate increased phenolics concentration in roots much more if no Mn was added, indicating that the resistance-enhancing effect of Mn may not be directly exerted through the effects on phenolics biosynthesis. Lignin concentration in roots decreased due to Mn fertilization, while no effect of take-all infection was noted. It appears that biosynthesis of phenolics and lignin in wheat roots has a low Mn requirement which can be satisfied at environmental Mn concentrations below those necessary for optimum plant growth. ei]Section editor: A C Borstlap ei]Section editor: H Lambers
