(Also known as: Thistle rosette weevil; Ceuthorhynchidius horridus) |
The following alerts are based on the data in the tables below. An absence of an alert does not imply the substance has no implications for human health, biodiversity or the environment but just that we do not have the data to form a judgement.

|
A phytophagous weevil that may be used for the biocontrol of thistles |
|
Mainly Carduus spp. and Cirsium spp. including nodding (musk) thistle (Carduus nutans) and plumeless thistle (Carduus acanthoides ) |
|
Pasture; Rangeland; Grassland |

|
Adult weevils are about 10mm long and reddish-brown when young but turn much darker with age. Female lays her eggs on the thistle plant. The hatched larvae feed mainly at the growing tip of the plant, stunting its growth and significantly reducing seed production. |
