The evidence for intraspecies chemical communication in insects is reviewed, with emphasis on those studies where known organic compounds have been implicated. These signal-carrying chemicals are known as pheromones. There are two distinct types of pheromones, releasers and primers. Releaser pheromones initiate immediate behavioral responses in insects upon reception, while primer pheromones ca...

Background & Aims: Neurogenesis in the adult mammal brain occurs throughout life. Adult neurogenesis has been clearly demonstrated in the sub granular zone (SGZ) of the dentate gyrus (DG) in the hippocampus. Pheromones that plays an essential role in the development of the central nervous system. The male pheromones are involved in regulating neurogenesis in both the olfactory bulb and hippocam...

Pheromone-binding proteins (PBPs) are essential for the filtering, binding and transporting of sex pheromones across sensillum lymph to membrane-associated pheromone receptors of moths. In this study, three novel PBP genes were expressed in Escherichia coli to examine their involvement in the sex pheromone perception of Maruca vitrata. Fluorescence binding experiments indicated that MvitPBP1-3 ...

Pheromones are low molecular weight chemical substances that are produced by a plant or animal and cause a response in another individual of same or another spices. Pheromones can be of many different chemical types, to serve different functions even for survival of the individual. Pheromones are sending out subconscious scent signals to male or female that naturally trigger attraction, arousal...

Sex pheromones provide an important means of communication to unite individuals for successful reproduction. Although sex pheromones are highly diverse across animals, these signals fulfil common fundamental roles in enabling identification of a mating partner of the opposite sex, the appropriate species and of optimal fecundity. In this review, we synthesize both classic and recent investigati...

Moths can biosynthesize sex pheromones in the female sex pheromone glands (PGs) and can distinguish species-specific sex pheromones using their antennae. However, the biosynthesis and transportation mechanism for Type II sex pheromone components has rarely been documented in moths. In this study, we constructed a massive PG transcriptome database (14.72 Gb) from a moth species, Ectropis grisesc...
