O. Habustova et al., Influence of copper from the Kuprikol 50 fungicide on Colorado potato beetle adults studied by radionuclide X-ray fluorescence analysis, J RAD NUCL, 243(3), 2000, pp. 825-826
The influence of copper on adults of the Colorado potato beetle (Leptinotar
sa decemlineata Say) was studied. The adults were treated by the contact fu
ngicide Kuprikol 50, which is used to control down powder mildew (Phytophto
ra infestans de Bary). Copper content was determined by radio-nuclide X-ray
fluorescence analysis using a Pu-238 exciting source. The obtained results
contribute to the control measures against the Colorado potato beetle and
to the question of the resistance of Colorado potato beetle towards pyrethr
oide insecticides.
