From mid-July onwards the beetles enter aestivation in sheltered sites ( Bonnemaison and Jourdheuil, 1954 Williams and Carden, 1961). After the rape is harvested the beetles may move to feed on wild crucifers ( Bonnemaison and Jourdheuil, 1954 Saringer, 1984). Alford (1979) found large numbers on rape stubble in July. About two weeks after emergence they move to their summer feeding sites to feed on the leaves, stems and pods of the rape plant ( Ebbe-Nyman, 1952). Adults emerge from pupation in the spring ( Williams and Carden, 1961). (1994) showed that glucosinolates are important feeding cues for this species. These plants contain glucosinolates, secondary chemicals that characterise the Brassicaceae and, in subsequent experiments, Bartlet et al. The only plants outside the Brassicaceae on which feeding was observed were Reseda alba (Resedaceae) and Tropaeolum majus (Tropaeolaceae). nigra, Sinapis alba, Sinapis arvensis, Eruca vesicaria, Nasturtium officinale, Raphanus sativus, Isatis tinctoria, Alliaria petiolata and Matthiola incana. However, in laboratory experiments, feeding was almost entirely restricted to the Brassicaceae ( Bartlet and Williams, 1991), including Brassica napus, B. chrysocephala have been recorded from 18 different crop and weed species of the family Brassicaceae but from only three plant species outside this family, namely Thalictrum majus, (Ranunculaceae), Linum usitatissum (Linaceae) and Glycine max (Papilionaceae) ( Newton, 1929 Bonnemaison and Jourdheuil, 1954). chrysocephala has not been thoroughly studied, most studies on crucifer-feeding Chrysomelidae concentrating on the genera Phyllotreta and Phaedon.
