Erysimum cheiranthoides

Erysimum cheiranthoides L., E. amurense Kitag. var. bungei (Kitag.) Kitag. 

Digitoxin (360) and cymarin (361) found in Erysimum cheiranthoides (Cruciferae) was previously found to be an active oviposition deterrent for two Pieris species.156 Tested against the cabbage looper, T. ni, both were active antifeedants, reducing feeding by 50% at a concentration of 18.8 and 10.8 pgcm 2, respectively.146...

The monosaccharide components will now be discussed. Usually, the component attached directly to the aglycon is of primary interest, because the odd or unusual sugars are almost always found in this place, an exception being D-xylose in the second position in glycoside I of Erysimum cheiranthoides. ...

The host range of the diamondback moth, Plutella xylos-tella, appears to be correlated with the presence of glucosinolates in the host plants, but the role of stimulants and attrac-tants in oviposition seem to be important. Extracts of Brassica oleracea (cabbage), B.juncea (mustard), and Erysimum cheiranthoides stimulated oviposition by gravid females on bean plants. Extracts of Erysimum cheiranthoides, Tropaeolum majus, and Capsella bursa-pastoris which deterred oviposition by the cabbage butterfly Pieris rapae, were not deterrent to Plutella xylostella (Renwick and Radke, 1990).
