Effect of some dietary o-dihydroxyphenols and quinones on hydrogen peroxide (H2O2) concentration within tissues of the grain aphid Sitobion avenae (F.) (Homoptera, Aphididae) has been studied. Among the studied aphid morphs the highest level of H2O2 total was noted for winged adults (alatae) and the lowest for larvae. The aphids exposed to the dietary pro-oxidative o-dihydroxyphenols demonstrated significantly higher concentration of hydrogen peroxide than the control ones. Among the studied compounds, caffeic acid showed the strongest effect on the H2O2 level within the aphid tissues. The highest concentration (0.1%) of this phenolic acid caused above 2-fold increase in the content of this radical within the grain aphid tissues. The significance of these results for understanding the toxicity of phenols to cereal aphids is discussed.

The aim of the present study was to compare ascorbate (ASA) content and ascorbate peroxidase (APX) activity in seedlings of the less susceptible triticale cultivar Witon and the more susceptible triticale cultivar Tornado after infestation by the grain aphid Sitobion avenae (F). and the bird cherry-oat aphid Rhopalosiphum padi (L.). The content of ASA in triticale seedlings slightly decreased after 24 hrs of infestation by cereal aphids, but prolonged feeding (48 hrs and 72 hrs) resulted in significant losses in ASA dependent on cultivar and aphid species. The aphid infestation caused an increase in APX activity in triticale tissues throughout the test period. The aphid herbivores induced APX activity to a higher level in a less susceptible cultivar than in a more susceptible one. The oligophagous species R. padi caused a higher decrease of ASA and stronger induction of APX activity in tested triticale than the monophagous species S. avenae. The experiments carried out indicate that ascorbate and ascorbate peroxidase may play a significant role in the defense mechanism of aphid infested triticale.

Flavonoids play an important role in interactions of plants with the environment. Liquid chromatography (HPLC) was used to determine the flavonoid profiles (especially luteolin, tricin, and chrysoeriol glycosides), their total concentrations, and changes in the amounts of eight flavones found in the aerial parts of alfalfa (Medicago sativa L.) (Fabaceae) Radius cv., uninfested and infested by the pea aphid (Acyrthosiphon pisum Harris) (Homoptera: Aphididae). It was shown that both control and infested green aerial parts of alfalfa plants had similar flavonoid profiles. The dominant flavonoid of alfalfa was compound 7-O-[2-O-feruloyl-β-D-glucuronopyranosyl( 1→2)-O-β-D-glucuronopyranosyl]-4’-O-β-D-glucuronopyranosideluteolin. Compound 7-O-{2’-O-feruloyl-[β-D-glucuronopyranosyl(1→3)]-O-β-D- glucuronopyranosyl(1→2)-O-β-D- glucuronopyranosidetricin was present in the smallest amounts. The total concentration of flavones was rather high and ranged from 11.13 to 12.34 mg/g d.m., but there were no significant differences between uninfested and infested alfalfa plants. There was a correlation between the concentration of flavonoid glycosides in the alfalfa plants and pea aphid abundance. Pea aphid daily fecundity per female was affected by luteolin, tricin, and chrysoeriol glycosides and the level of chrysoeriol glycosides affected ingestion of xylem sap by the aphid. This finding may indicate that the studied flavonoid glycoside forms are biologically active in alfalfa – A. pisum interactions.

Podjęto badania nad akumulacją metali ciężkich Zn, Cd i Pb przez populacje Silene vulgaris z gleby zanieczyszczonej metalami w obecności i przy braku EDTA (kwasu etylenodiaminotetraoctowego). Nasiona pozyskano z trzech stanowisk: (1) najbliższego otoczenia Huty Metali Nieżelaznych „Szopienice” w Katowicach, (2) hałdy pocynkowej Zakładów Metalurgicznych „Silesia” w Katowicach, (3) obszaru pogalmanowego w Dąbrowie Górniczej (Warpie). Gleba była zanieczyszczana Pb, Zn i Cd. Dodawano także EDTA do gleby zanieczyszczonej metalami. Badano akumulację metali ciężkich w liściach, łodygach i korzeniach roślin S. vulgaris. Obliczono wskaźniki translokacji (TF). Dodatek EDTA spowodował wzrost biodostępności metali ciężkich w glebie. W obecności EDTA zanotowano zwiększoną akumulację Zn i Cd w częściach nadziemnych Silene vulgaris oraz Pb u roślin pochodzących z najbliższego otoczenia huty (Szopienice). Najwyższą akumulację Cd i Zn stwierdzono w liściach badanych roślin. U roślin Silene vulgaris, rosnących na glebie z dodatkiem EDTA zanotowano także większą translokację Zn i Cd do części nadziemnych.
