Importance and distribution in Luxembourg
The invasion of the Grand-Duchy of Luxembourg by the Colorado potato beetle started in 1936; the bug was first found on 23rd June 1936 in Steinsel-Müllendorf, then in Limpertsberg, Mamer and Neuhäuschen. In 1937 it was reported from Eischen, Finsterthal and Beyren. In 1938 the whole country was infested. The details of this invasion were published by Jos Massard (2000).
The actual distribution of the species is still widespread all over the country, but the populations have sharply decreased, especially because of the decline of the potato production, e.g. from >17000 ha in 1939 to 800 in 1995 (Massard 2000: 212).
Only 6 occurrences of the species are documented in the Recorder database, ranging from 1968 to 2015 (06/02/2018).
Colorado beetles are a serious pest of potatoes. They may also cause significant damage to tomatoes and eggplants. Both adults and larvae feed on foliage and may skeletonize the crop.
ISEIA protocol: C3 (3+1+1+1) (Ries et al. 2017: 68).
