Abstract
Electroantennograms EAGs were recorded from males and females of the potato tuber moth Phthorimaea operculella in response to a broad range of plant volatile compounds belonging to diverse chemical classes The responses to 27 compounds were evaluated which indicated significant differences in EAGs between chemicals as well as between sexes The fatty acid derivatives comprising essentially green leaf volatile components elicited significantly greater responses in females The response profile of males was in general lower than that of females EAG responses to the oxygenated and hydrocarbon monoterpenes were lower in both males and females Doseresponse studies indicate differences in response between the sexes and concentrations suggesting the existence of sexual dimorphism Compounds belonging to the fatty acid derivatives class appear to be important for an oligophagous pest such as the potato tuber moth and the findings are discussed in relation to host plant selection in this species
