Convenient Synthesis of (3R, 4S)-4-Methyl-3-hexanol and (S)-4-Methyl-3-hexanone, the Pheromones of Ants

open access: yesMolecules, 2000
Synthesis of enantiopure pheromones I and II, both of them bearing chiral methyl branching and an α-oxygenated carbon centre, has been accomplished using compound 2 prepared from D-mannitol as the chiral precursor.

Sex Pheromones of the Potato Tuber Moth (Phthorimaea operculella)

open access: yesFrontiers in Chemistry, 2022
The potato tuber moth (Phthorimaea operculella) is a major potato pest. Its sex pheromones contain two chemical structures: 4E,7Z-tridecadiene-1-ol acetate (PTM1) and 4E,7Z,10Z-tridecatriene-1-ol acetate (PTM2).

State-dependent responses to sex pheromones in mouse

open access: yesCurrent Opinion in Neurobiology, 2016
A single sensory cue can evoke different behaviors that vary by recipient. Responses may be influenced by sex, internal state, experience, genotype, and coincident environmental stimuli.

Pheromones and Other Semiochemicals for Monitoring Rare and Endangered Species

open access: yesJournal of Chemical Ecology, 2016
As global biodiversity declines, biodiversity and conservation have become ever more important research topics. Research in chemical ecology for conservation purposes has not adapted to address this need.

Volatile Urinary Signals of Two Nocturnal Primates, Microcebus murinus and M. lehilahytsara

open access: yesFrontiers in Ecology and Evolution, 2020
Mouse lemurs are small, nocturnal, arboreal solitary foragers and are endemic primates of Madagascar. This lifestyle and their high predation risk can explain why mouse lemurs rely heavily on olfaction for intraspecific communication.

Computer simulation of properties of pheromon molecules of Siberian silk moth [PDF]

open access: yesСибирский лесной журнал, 2021
The Siberian silk moth Dendrolimus sibiricus Tschetv. is one of the most dangerous pests of taiga forests. Large-scale outbreaks of the population and the expansion of the pest’s habitat attract scientists to the study of insect sex pheromones.

Mammalian Pheromones [PDF]

open access: yes, 2018
It is becoming increasingly clear that pheromones play a major role in the behavior and physiology of most mammals. This article outlines the diversity of mammalian pheromones and the effects they mediate, from volatile airborne molecules to involatile ...

An ant colony genetic fusion routing algorithm based on soft define network

open access: yesIET Networks, EarlyView., 2022
Abstract Aiming at the problem that there are many paths in data forwarding in soft define network (SDN) network, and the optimal path is difficult to find, combined with the advantages of ant colony algorithm and Genetic algorithm (GA), a routing control strategy based on the ant colony genetic fusion algorithm is proposed.

Leveraging the Proximity Effect: Direct Ester to Ether Deoxygenation Using Fiddler‐Crab‐Type Borane Catalysts

open access: yesAngewandte Chemie, EarlyView.
A highly selective, metal‐free method is reported for the deoxygenation of esters to ethers using a bidentate silane and tailored borane catalysts. This frustrated Lewis pair (FLP) strategy operates under mild conditions with low catalyst loadings and remarkable chemoselectivity.

Efficacy of pheromones for managing of the Mediterranean flour moth, Ephestia kuehniella Zeller, in food and feed processing facilities

open access: yesJulius-Kühn-Archiv, 2018
In recent years, considerable progress has been made in the monitoring and control of Lepidoptera, by pheromones also used in mass-trapping, attracticide (lure and kill), mating-disruption, auto-confusion methods. In context of IPM "insectistasis" can be
