What Is a Pheromone? Mammalian Pheromones Reconsidered [PDF]

Neuron, 2005
Pheromone communication is a two-component system: signaling pheromones and receiving sensory neurons. Currently, pheromones remain enigmatic bioactive compounds, as only a few have been identified, but classical bioassays have suggested that they are nonvolatile, activate vomeronasal sensory neurons, and regulate innate social behaviors and ...

Sex pheromone evolution is associated with differential regulation of the same desaturase gene in two genera of leafroller moths. [PDF]

PLoS Genetics, 2012
Chemical signals are prevalent in sexual communication systems. Mate recognition has been extensively studied within the Lepidoptera, where the production and recognition of species-specific sex pheromone signals are typically the defining character ...

Individual rules for trail pattern formation in Argentine ants (Linepithema humile) [PDF]

, 2012
We studied the formation of trail patterns by Argentine ants exploring an empty arena. Using a novel imaging and analysis technique we estimated pheromone concentrations at all spatial positions in the experimental arena and at different times.

Physiological state of female and light intensity affect the host-plant selection of carrot psyllid, Trioza apicalis (Hemiptera: Triozidae)

European Journal of Entomology, 2008
We have studied the effect of different light gradient regimes on host-plant selection of the carrot psyllid, Trioza apicalis Förster. In both a strong and a weak light gradient, carrot psyllids preferred a carrot leaf placed in higher light intensity ...

Pheromones [PDF]

Current Biology, 2017
The reality of invisible chemical signals, pheromones, between members of the same species was recognized long before they could be identified. Charles Darwin proposed that the breeding season sexual smells of male crocodiles, goats and other animals, too, could have evolved by sexual selection of the smelliest males through female choice. But it's not

Effect of trail bifurcation asymmetry and pheromone presence or absence on trail choice by Lasius niger ants [PDF]

, 2014
During foraging, ant workers are known to make use of multiple information sources, such as private information (personal memory) and social information (trail pheromones).

The influence of evaporated pheromone upon the trapping of the spruce bark beetle - Ips typographus (L.) (Coleoptera: Curculionidae: Scolytinae) - Short communication

Journal of Forest Science, 2017
This article examines the relative efficacy of releasing a larger pheromone plume volume and the relative efficacy of the number of pheromone dispensers within baited traps in trapping the spruce bark beetle.

Effect of Collection Month, Visible Light, and Air Movement on the Attraction of Male Agriotes obscurus L. (Coleoptera: Elateridae) Click Beetles to Female Sex Pheromone

Insects, 2020
Elaterid female sex pheromone, while currently used for monitoring the adult life stage (click beetle), has only recently been explored as a potential management tool.

An effective ant-colony based routing algorithm for mobile ad-hoc network [PDF]

, 2008
An effective Ant-Colony based routing algorithm for mobile ad-hoc network is proposed in this paper. In this routing scheme, each path is marked by path grade, which is calculated from the combination of multiple constrained QoS parameters such as the ...

Distinct protocerebral neuropils associated with attractive and aversive female-produced odorants in the male moth brain

eLife, 2021
The pheromone system of heliothine moths is an optimal model for studying principles underlying higher-order olfactory processing. In Helicoverpa armigera, three male-specific glomeruli receive input about three female-produced signals, the primary ...
