This website presents three unpublished studies related to insect olfaction of plant odour. 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 But l still felt obliged to share this information and, therefore, presented the unpublished studies on the website (2010). In I have updated the website to WordPress. I hope you enjoy the new version. 🙂
