Abstract
The behavioural and sensory responses of cabbage seed weevils Ceutorhynchus assimilis Payk. to oilseed rape Brassica napus L. odour were studied. At seed weevil emergence sites, significantly more weevils were caught in yellow water traps baited with Industrial Methylated Spirit (IMS) extracts of oilseed rape leaf and flower odour (970 and 722 weevils respectively) than the IMS control baits (seven weevils). The attraction of seed weevils to oilseed rape leaf and flower odour was also demonstrated in the laboratory using a four-choice olfactometer (Vet et al., 1983).
