Abstract:		"The cabbage stink bugs of the genus Eurydema, encompassing several oligophagous species, such as Eurydema oleracea (L.), are known to be important pests of cabbage, broccoli, and other cole crops in Europe. Despite their economic importance, the knowledge regarding the role of chemical cues in host plant selection of these species is very limited. The present investigation on E. oleracea at the adult stage revealed the use of olfaction in host plant selection of this species and demonstrated with behavioural tests that E. oleracea preferred feeding on wild Eruca sativa, rather than on Brassica oleracea. Moreover, ultrastructural data revealed the antennal sensilla of E. oleracea, encompassing single walled and double walled olfactory sensilla, and electroantennographic recordings revealed their sensitivity to several host plant VOCs from E. sativa and B. oleracea. The data shown in the present research may be useful in the development of semiochemical-based strategies or trap crops for the control of this pest in the field"
