Negative effect of fungicides used in practical hop protection against downy mildew (Pseudoperonospora humuli) on aphidophagous coccinellids Propylea quatuordecimpunctata L.

Popis výsledku v původním jazyce

Still increasing attention has been paid to the development of IPM systems within EU countries. Natural enemies play a very important role in these systems. Therefore, it is necessary to use only such pesticides, whose harmfulness is generally lower andacceptable. Downy mildew (Pseudoperonospora humuli) is commonly controlled by fungicides applied during the season. Nevertheless, at that time numerous aphidophagous predators, especially coccinellids are present on leaves of the treated plants feeding on aphids. Ladybird Propylea quatuordecimpunctata L. belongs to the most important species attacking damson-hop aphid (Phorodon humuli Schrank). Fungicides, which are in current use, were tested on eggs, larvae, pupae and adults of this ladybird species to determine their real effect and convenience of their inclusion within IPM systems. The fungicides tested in the bioassays increased the mortality rate of each developmental stage of P. quatuordecimpunctata. Adults of coccinellids were m
