TL;DR: The study of apple volatiles eliciting an antennal response, together with a survey of the seasonal change in the release of these compounds, is the first step toward the identification of volatile mediating host-finding and oviposition in codling moth females.

TL;DR: A scanning electron microscopic study of the antennae of both sexes supported an earlier study, apart from that long s.trichodea were present in a wreath at the proximal margin of the flagellomere and in addition evenly distributed over the remaining surface, and a previously non-described sensillum type with external basiconic features was revealed.

TL;DR: Attraction of codling moth to compounds eliciting a strong antennal response was tested in a wind tunnel and male moths were best attracted to a blend of (E,E)‐α‐farnesene, (E]‐beta‐farrellesene and ethyl E,E‐2,4‐decadienoate.

TL;DR: Oviposition in wild codling moth females, collected as overwintering larvae from apple, pear and walnut, was stimulated by volatiles from fruit-bearing green branches of these respective hostplants, suggesting a considerable plasticity in the female response to host plant odours.

TL;DR: Results of gas chromatography‐electroantennographic detection (GC‐EAD) experiments showed that cotton bollworm antennae responded to seven compounds and two minor unknown compounds in Bt volatiles, among which concentrations of α‐pinene and β‐pinsene in BT cotton were relatively higher than those in regular cotton, and one minor unknown compound was absent in regularotton.
