Weevils (Coleoptera: Curculionoidea): Important members of rapeseed entomofauna in vicinity of Novi Sad

Abstract

The area under rapeseed is increasing in the world as well as in Serbia, which makes appearance and harmfulness of some insects more important. Weevils (Coleoptera: Curculionoidea) are group of insects whose presence and destructiveness on oilseed rape are not explored enough. Results of rapeseed entomofauna exploration at site Rimski Šančevi during 2008 are presented in this paper. Insects were collected using yellow traps method, also known as Moericke's dishes, which can be considered as one of the most appropriate methods for this kind of research. During spring, 433 adult specimens were collected (all belong to five genera and ten species). More than tenfold less specimens were collected in autumn - 42 (seven genera and 11 species). The most abundant genus was Ceutorhynchus, and species Ceutorhynchus pallidactylus (Marsham) (=quadridens Panzer). .
