She became an instructor at the institution in 1924 but decided to immigrate to the United States after visiting a relative, who served at the time as the Hungarian consul in Cleveland.

While it is especially problematic for citrus and apple trees, it can attack many other plant species.

Aphids suck: Invasive aphid found on Danish apple trees

Date Time Aphids suck: Invasive aphid found on Danish apple trees The spirea aphid, Aphis spiraecola, an invasive pest, has been discovered for the first time in Denmark by University of Copenhagen researchers. The extent of its current distribution remains unknown, but in time, it could prove to be a troublesome pest for Danish apple growers. Whether the discovery of this aphid in Denmark is an isolated incident, or if the species has made itself at home due to a milder climate, remains unknown to the researchers. Closer investigation is needed.
