Male sex pheromone in the parasitoid wasp Nasonia longicornis: Chemical and behavioral analyses

Frontiers in Ecology and Evolution, 2022
The use of sex pheromones for the attraction of potential mating partners is widespread in insects. Species-specificity of these chemical signals is essential, particularly in closely related species with overlapping habitats.

Potential application of the bumblebee foraging recruitment pheromone for commercial greenhouse pollination [PDF]

, 2009
Commercial bumblebee colonies are important crop pollinators. Here we assess whether application of artificial foraging recruitment pheromone can increase foraging activity in Bombus terrestris colonies on a relevant timescale for commercial pollination.

A challenge for a male noctuid moth? Discerning the female sex pheromone against the background of plant volatiles

Frontiers in Physiology, 2016
Finding a partner is an essential task for members of all species. Like many insects, females of the noctuid moth Heliothis virescens release chemical cues consisting of a species-specific pheromone blend to attract conspecific males.

Complex Nature of Enterococcal Pheromone-Responsive Plasmids

Polish Journal of Microbiology, 2010
Pheromone-responsive plasmids constitute a unique group of approximately 20 plasmids identified, as yet, only among enterococcal species. Several of their representatives, e.g. pAD1, pCF10, pPD1 and pAM373 have been extensively studied. These plasmids possess a sophisticated conjugation mechanism based on response to sex pheromones--small peptides ...

Field evaluation of synthetic aphid sex pheromone in enhancing suppression of aphid abundance by their natural enemies [PDF]

, 2016
The effects of lures containing aphid sex pheromone components (4aS,7S,7aR)-nepetalactone and (1R,4aS,7S,7aR)-nepetalactol on abundance of pea aphid, Acyrthosiphon pisum Harris, aphid parasitoids, predators and hyperparasitoids in alfalfa fields were ...

2-methyl-3-buten-2-ol: a pheromone component of conifer bark beetles found in the bark of nonhost deciduous trees [PDF]

, 2012
Volatiles from bark of aspen,Populus tremulaL. and two species of birch: silver birch (Betula pendulaRoth.) and common birch (B. pubescensEhrh.), were collected by direct solvent extraction and aeration of both newly cut bark chips and undamaged stems in

Identification of an aphid sex pheromone. [PDF]

, 1987
Although aphids reproduce asexually on their host plants during the summer, many species migrate to a winter host where sexual reproduction occurs. Males of certain species locate mates by means of a sex attractant pheromone released from the hind legs ...

Honeybee communication during collective defence is shaped by predation

BMC Biology, 2021
Background Social insect colonies routinely face large vertebrate predators, against which they need to mount a collective defence. To do so, honeybees use an alarm pheromone that recruits nearby bees into mass stinging of the perceived threat.

Conditional deletion of ERK5 MAP kinase in the nervous system impairs pheromone information processing and pheromone-evoked behaviors. [PDF]

PLoS ONE, 2013
ERK5 MAP kinase is highly expressed in the developing nervous system but absent in most regions of the adult brain. It has been implicated in regulating the development of the main olfactory bulb and in odor discrimination.
