Opis:: In 1998 and 1999, the research on the contents of entomofauna settlement of Heracleum Sosnowskyi Manden was carried out at Mochełek, and in 1999 - at Minikowo near Bydgoszcz. Useful insects were the most abundant group in the tested habitats. Based on the results of the investigations, it can be concluded that only two species: blunt’s flat-body (Depressaria depresella Hb.) and celery fly (Phillophylla heraclei L.) may be of any importance in the fight against population of this plant.
W latach 1998 i 1999 przeprowadzono badania w Stacji Badawczej Wydziału Rolniczego ATR w Mochełku i w Ośrodku Doradztwa Rolniczego w Minikowie k. Bydgoszczy. Celem było poznanie entomofauny zasiedlającej barszcz sosnowskiego (Heracleum Sosnowskyi Manden) i przebadanie jej pod kątem możliwości ewentualnego wykorzystania w biologicznym jego zwalczaniu. Najliczniejszą grupę w badanych siedliskach stanowiły owady pełniące pożyteczną rolę. Z analizy wyników można wnioskować, że tylko dwa szkodniki: płozek marchwiaczek (Depressaria depressella Hb.) i liściolubka selerowa (Philophylla heraclei L.) mogą odegrać rolę przy zwalczaniu populacji tej rośliny.

Opis:: Influence of some selected heavy metals applied into soil as water salt solutions (2 mg Cd, 30 mg Cu, 15 mg Ni, 80 mg Pb and 70 mg Zn/kg soil d.m.) on the growth and development of broad beans and on occurrence of harmful and beneficial insects on the plant was investigated in field conditions. The applied doses of soil contamination with heavy metals strongly affected broad beans development. Plants were characterised by a significantly lower number and length of shoots and a lesser number of pods per plant as compared to the control. Chemical analysis of individual parts of plant revealed big differences in heavy metal contents in roots of plants in contaminated soil as compared to control soil with natural contents of metal ions. In the above ground parts, i.e. leaves and shoots the differences were considerably smaller. Numbers of beetroot aphids were determined on the selected plants since its appearance to the end of its development. Simultaneously, occupation of aphid colony by predators: ladybirds, Syrphidae and Chrysophidae larvae was also assessed. The number of plants occupied by aphids at each plot was also estimated. Aphids on plants in soil with increased metal contents formed more numerous colonies, also the insects invaded a bigger number of plants. Ladybird larvae, predators for aphids, occurred in more numerous colonies on plants in contaminated soil. The numbers of other aphid predators: Syrphidae and Chrysophidae larvae did not reveal statistically significant differences.
