“…Whereas it is generally known within the chemical ecology community that each method has its biases, it is useful to have a careful, qualitative, and quantitative study that systematically compares those biases. The second paper, by Weliton Silva and coauthors (Silva et al 2021) describes the identification of pheromone components from several South American cerambycid beetle species. Some of the first work on cerambycid pheromones was done in Professor Francke's group in the 1990s, and one of the compounds that his group identified, 3-hydroxyhexan-2one, is continuing to be found in the pheromone blends of cerambycid beetles worldwide, including the species described in this study.…”
