This review covers the research on brown algal pheromones from the first structural characterisation of an active principle in 1971 to the recent detailed insight into their biosynthesis. Development of analytical methods and bioassays that lead to the identification of a structural variety of different fatty acid-derived pheromones are reported. Special emphasis is focused on the inactivation ...

BACKGROUND Carboxyl/cholinesterases (CCEs) are highly diversified in insects. These enzymes have a broad range of proposed functions, in neuro/developmental processes, dietary detoxification, insecticide resistance or hormone/pheromone degradation. As few functional data are available on purified or recombinant CCEs, the physiological role of most of these enzymes is unknown. Concerning their r...

Abstract Hymenopteran females are mostly highly selective, choosing their mating partner according to male quality signals, and may also signal fertility through chemical advertisement. Male insects, in turn, often display a complex set of courtship behaviors allure mate. In this study we explored the mechanisms triggering oligolectic bee Heriades truncorum . species, males perform wing fanning...

23 Experiments were conducted in North and South America during 2012-2013 to 24 evaluate the use of lure combinations of sex pheromones (PH), host plant volatiles 25 (HPV), and food baits in traps to capture the oriental fruit moth, Grapholita molesta 26 (Busck) and codling moth, Cydia pomonella (L.) in pome and stone fruit orchards 27 treated with sex pheromones. The combination of the sex phe...

Mammalian pheromones control a myriad of innate social behaviors and acutely regulate hormone levels. Responses to pheromones are highly robust, reproducible, and stereotyped and likely involve developmentally predetermined neural circuits. Here, I review several facets of pheromone transduction in mammals, including (a) chemosensory receptors and signaling components of the main olfactory epit...
