This website presents three unpublished studies related to insect olfaction of plant odour. So studies are published with this website on beetle orientation towards plant odour (servosphere tests), aphid electroantennograms and bioassays of aphid repellents. During my employment as insect physiologist at the Wageningen Agricultural University I did not find enough time to publish these studies. But l still felt obliged to share this information and, therefore, presented the unpublished studies on the website olfacts.nl (2010). In olfacts.com I have updated the website to WordPress. I hope you enjoy the new version. 🙂
