Abstract

Research on identification of Ceutorhynchus Species in winter oilseed rape was done during the vegetation seasons of 2010 and 2011. Weevils were sampled in using Moericke's type yellow water traps during the period from March to harvest of oilseed rape. Eleven species of weevils were identified: C. pallidactylus, C. obstrictus C. floralis C. napi, C. rapae, C. erysimi, C. sulcicollis, C. ruglosus, C. gallorheranus, C. pleurostigma and C. rusticus. The most common species were C. pallidactylus, C. obstrictus and C. floralis. During experimental period the first catches of C. pallidactylus were registered at the time when an average daily air temperature reached 8.4-9.2 degrees C and C. obstrictus--at the temperature 16.6-19.9 degrees C.
