Virgin female clearwing moths (Sesiidae),Synanthedon pictipes(Grote and Robinson) female extracts, and isomers of 3,13-octadecadien-1-ol acetate (ODDA) were evaluated for attractancy to male clearwings.Podosesia syringae(Harris) females attracted conspecific males and males in 3 other genera in 2 subfamilies, whileS. pictipesfemales and female extracts attracted only conspecific males.(Z,Z)-ODDA attracted significant numbers of 4 sesiid species, while a mixture of 3 isomers of this compound attracted large numbers ofSanninoidea exitiosa(Say). (E,Z)-ODDA attracted onlyS. pictipesmales.Sesiids may be especially vulnerable to manipulation by these highly attractive synthetic sex attractants because these moths are relatively scarce even at pest population density, and quite host specific.
