Stem mining weevils, rape stem weevil (Ceutorhynchus napi Gyll. 1837) and cabbage stem weevil (Ceutorhynchus pallidactylus Marsh. 1802) have become more important oliseed rape pests. Rape stem weevil is present in middle and west European countries and cabbage stem weevil is present in almost all European countries. The most important morphological difference between adults is colour of their legs. Biological and ecological characteristics of these two pests are similar, stem mining weevils are observed as pest complex. Differences in biology cause different approach in pest control.
Both species have single generation annually. Larvae feed inside the petioles and stems of oilseed rape. Phyrethroids are used for adult control of stem mining weevils.
