The sexuales of giant black bark aphid, Pterochloroides persicae (Hemiptera, Aphidoidea: Lachninae).
The oviparous female and male of the giant black bark aphid Pterochloroides persicae (Cholodkovsky) are described and illustrated for the first time. Notes on distribution, biology and host plants are presented.

Empirical rules of solar-cycle evolution form important observational constraints for the solar-dynamo theory. This includes Waldmeier rule relating magnitude a solar cycle to length its ascending phase, and Gnevyshev–Ohl clustering cycles pairs an even-numbered followed by stronger odd-numbered cycle. These were established as based on “classical” Wolf sunspot number series, which has been ess...
We congratulate Romano, Shaikh, and Wolf for their interesting work. Our only criticism to the presentation of the article, which is otherwise very readable, concerns Remark 1 on p. 8. This is crucial to understanding the method, because it explains that the estimates of the probabilities under the null are determined by the smaller test statistics, so it should have been made explicit at an ea...
The enantiomerically enriched γ- and δ-decalactones (4a and 4b) were prepared from corresponding racemic primary-secondary 1,4- and 1,5-diols (1a and 1b), as products of enzymatic oxidation catalyzed by different alcohol dehydrogenases. The results of biotransformations indicated that the oxidation processes catalyzed by alcohol dehydrogenase (HLADH), both isolated from horse liver and recombin...
The effect of dark-induced senescence on Solanum tuberosum L. (Solanales: Solanaceae) plants was assessed on the feeding behavior and performance of the green peach aphid, Myzus persicae Sulzer (Hemiptera: Aphididae). Senescence was induced by covering the basal part of the plant with a black cloth for 5 d, avoiding the light passage, but keeping the apical buds uncovered. The basal part of con...
Studies were conducted to examine the effect of treating Zinnia elegans Jacq. with soluble silicon on the performance of the green peach aphid, Myzus persicae (Sulzer). Z. elegans plants were irrigated every 2 d throughout the duration of the experiment with a nutrient solution amended with potassium silicate (K2SiO2), or a nutrient solution without K2SiO2. Length of the prereproductive period ...
Background: Cucumber mosaic virus (CMV) is one of the most important viruses infecting vegetables in the fields throughout the world. Transmission efficiency of CMV could depend on the variability of virus strain but also aphid vector species and/or clones. Materials and Methods: By sequence analysis, the coat protein gene of CMV strains from different regions revealed that the CMV isolates use...
Aphids are serious pests in crop plants. In an effort to identify plant genes controlling resistance against aphids, we have here studied a protease inhibitor, CI2c in barley (Hordeum vulgare L.). The CI2c gene was earlier shown to be upregulated by herbivory of the bird cherry-oat aphid (Rhopalosiphum padi L.) in barley genotypes with moderate resistance against this aphid, but not in suscepti...
