Abstract

During the last couple of years leaf-edge-cuts, typical of Otiorhynchus, a genus of wingless weevils, have been discovered on ornamental shrubs, especially on lilac (Syringa vulgaris) and privet (Ligustrum vulgare). An inventory was made in gardens in west Scania 2009.
The results show that we in Sweden have a new species of wingless-weevil, Dodecastichus inflatus (former known as Otiorhynchus inflatus). Further more, the weevil Otiorhynchus smreczynskii was shown to be established in a much larger geographic area than previously known. This species was the most common on lilac and privet and caused the majority of the damages. The morphology of these two species is described. The extension and appearances of the damages have been documented in order to see if different weevil species make different types of edge-cuts. Several weevil species have spred in gardens in our neighbouring countries during the last decades. The species most likely to occur more frequently
in Sweden are described. These six Otiorhynchus species, that are potential pests in our gardens, are: O. tenebricosus, O. salicicola, O. crataegi, O. dieckmanni, O. aurifer and O. armadillo.
