Purpose:The aim of this paper is to explore the impact of Facebook and Instagram on consumer buying behaviour in the retail fashion market in Rhodes, Greece. We look at the extent to which the two social media influence Rhodian consumer preferences toward certain stores and at whether Rhodians use these social media for fashion information and inspiration. Design/methodology/approach:The study is conducted online, using quantitative methodology and close-ended survey questionnaires to obtain data. Finding:We find that Facebook and Instagram influence Rhodian consumer behaviour. Rhodians believe that the two social media are a good way to follow fashion trends and that fashion is more accessible because of Facebook and Instagram compared to five years ago. The Rhodians seem to be getting fashion inspiration from Facebook and/or Instagram but more in a passive manner than through active engagement with fashion on the two social media. Research limitations/implications:Our findings demonstrate that Facebook and Instagram are very powerful in bringing fashion closer to consumers and they underline the role that these social media can plan in the marketing mix. Our findings can be used by fashion retailers to inform their social media engagement strategies and decisions. Our research can be extended to investigate the impact of different social media constructs on consumer behaviour and to look at what type of social media content may be more impactful in shaping shopping behaviour. Originality/value: Research on the subject of how social media impacts the behaviour of fashion consumers in Greece is limited and literature on the retail fashion market is noticeably scarce. Studies published on the topic of social media influencing consumer decisions with a focus on the Greek market are almost exclusively confined to the tourism sector. Our findings can be used by fashion retailers to inform their social media engagement strategies and decisions. JEL Classifications M30, M31, M39

Aggregation pheromones have been investigated as a source for a multispecies lure for Oryzaephilus surinamensis, Cryptolestes ferrugineus and Sitophilus granarius, using adult beetles that were generally 0- to 2-weeks old. S. granarius showed no significant electroantennogram (EAG) response to four macrolide lactones and R,S-1-octen-3-ol, at a single dose of 10 µg, indicating that this species is unable to perceive these compounds at the concentration tested. All three species showed an EAG response to racemic sitophinone, although the perception threshold ranged from 10 µg for S. granarius to 1000 µg for O. surinamensis. The behavioural effect of racemic sitophinone (500 ng for S. granarius and 50 µg for O. surinamensis and C. ferrugineus) and R,S-1-octen-3-ol (10 µg) was investigated for all three species in pitfall bioassays. As expected, there was significant attraction of S. granarius to racemic sitophinone compared to the control but no response by this species to R,S-1-octen-3-ol. Neither O. surinamensis nor C. ferrugineus was attracted to racemic sitophinone or R,S-1-octen-3-ol in pitfall bioassays. An investigation of the effect of insect age on the response to R,S-1-octen-3-ol showed that 3- to 5-week-old O. surinamensis had a lower threshold for behavioural response than 0- to 2-week-old adults, but there was no significant difference in response to 1, 10 or 100 ng R,S-1-octen-3-ol compared to the control for C. ferrugineus for either 0- to 2- or 4- to 6-week-old adults. The effect of R,S-1-octen-3-ol on O. surinamensis and C. ferrugineus requires further investigation to determine the reasons for the differences in response shown by different research groups. It is concluded that it is not possible to produce a multispecies lure for these three species based on racemic sitophinone and R,S-1-octen-3-ol.
