Life cycles, feeding patterns and herbivory intensities of two
chrysomelid species (Crepidodera pluta and Phratora vitellinae) were
analysed in the poplar (Populus x canadensis Moench) plantation over the
period of six months in 2014. Herbivory was measured as leaf area lost
and a number of damaged leaves per branch. For C. pluta was found to
have one generation per year, with peak abundance in August, while P.
vitellinae had one or two generations and a maximum abundance in July.
Both species expressed the lowest intensity of herbivory during the post
hibernation period in April, and the highest levels of herbivory in
July. Beetles completed their life cycles on P x canadensis but did not
attain maximum potential growth rates by feeding on this plant, which we
consider as a suboptimal food source. Chrysomelid damage was found to be
insignificant and did not affect tree vitality.
