Journal of Plant Protection Research is an international peer-reviewed journal that publishes original papers, rapid communications, reviews, covering all areas of plant protection. Subjects include phytopathological virology, bacteriology, mycology and applied nematology and entomology as well as topics on protecting crop plants and stocks of crop products against diseases, viruses, weeds etc.
The Journal is published by Institute of Plant Protection – National Research Institute and Committee on Agronomic Sciences of the Polish Academy of Sciences. By 1997 under the title Prace Naukowe Instytutu Ochrony Roślin and Annals of Agricultural Sciences - Series E - Plant Protection).
JPPR publishes original research papers, rapid communications, critical reviews, and book reviews covering all areas of modern plant protection. Subjects include phytopathological virology, bacteriology, mycology and applied nematology and entomology as well as topics on protecting crop plants and stocks of crop products against diseases, viruses, weeds etc. We publish papers which use an interdisciplinary approach showing how different control strategies can be integrated into pest management programmes, which cover high and low input agricultural systems worldwide, within the framework of ecologically sound and economically responsible land cultivation.
Relevant topics include: advanced methods of diagnostic, and computer-assisted diagnostic plant research and new findings, biological methods of plant protection, selective chemical methods of plant protection, the effects of plant-protecting agents and their toxicology, methods to induce and utilize crop resistance, application techniques, and economic aspects of plant protection.

Toxicity and physiological alterations were determined in Pseudococcus viburni nymphs treated with Artemisia annua methanolic extract. The leaf dipping bioassay showed LC50 values of 0.287% and 0.194% 24 and 48 hours post-exposure. Activities of general esterases were significantly higher in the control nymphs than in those which had been treated except for the 48 h time interval using α-naphtyl acetate. The activity of glutathione S-transferase using CDNB (1-chloro-2,4-dinitrobenzene) in the control nymphs, was significantly higher than in the control at both time intervals while no significant difference was observed after 24 h in addition to the higher enzymatic activity in the treated nymphs after 48 h. All three aminotransferases were significantly more active in the control nymphs except for time intervals of 24 h for γ-glutamyl transferase and 48 h for alanine aminotransferase. Higher activities of lactate dehydrogenase, acid- and alkaline phosphatase were found in the control nymphs than in treated nymphs for all time intervals. Activities of the enzymes involved in the antioxidant system including catalase, peroxidase, superoxide dismutase, ascorbate peroxidase and glucose-6-phosphate dehydrogenase was increased in the treated nymphs compared to the control. Results of the current study demonstrated toxic effects of A. annua methanolic extract on P. viburni nymphs causing mortality and physiological turbulences.
