have been made in field olfactometers with brevicomin, which was identified in the frass of female D. brevicomis (6). The material has consistently given indifferent results or been totally ineffective. However, when a representative assortment of natural terpenes was tested in conjunction with brevicomin, 3-carene proved to be effective in activating the substance. 3-Carene was superior to myr...

During the last decades, manuscripts have become increasingly available through digitization and deposition in online repositories. This trend has very much facilitated primary source research, as scholars are no longer subjected to time- effort-consuming processes such travel, applications for photography permissions, so on. In this framework, authors set forth results of research that deals w...
