A Versatile Vision-Pheromone-Communication Platform for Swarm Robotics

, 2021
This paper describes a versatile platform for swarm robotics research. It integrates multiple pheromone communication with a dynamic visual scene along with real time data transmission and localization of multiple-robots.

Genetic control of conventional and pheromone-stimulated biofilm formation in Candida albicans.

PLoS Pathogens, 2013
Candida albicans can stochastically switch between two phenotypes, white and opaque. Opaque cells are the sexually competent form of C. albicans and therefore undergo efficient polarized growth and mating in the presence of pheromone.

Effectiveness of Various Solar Light Traps With and Without Sex Pheromone for Mass Trapping of Tomato Leaf Miner (Tuta absoluta) in a Tomato Field

Notulae Scientia Biologicae, 2018
Tuta absolute was a quarantine pest in Iran that has been recorded for the first time in 2009. The most conventional methods for control of this pest in Iran are chemical methods and mass trapping, although the efficiency of the latter method is not ...

Production of Long Chain Fatty Alcohols Found in Bumblebee Pheromones by Yarrowia lipolytica

Frontiers in Bioengineering and Biotechnology, 2021
Fatty alcohols (FA-OH) are aliphatic unbranched primary alcohols with a chain of four or more carbon atoms. Besides potential industrial applications, fatty alcohols have important biological functions as well. In nature, fatty alcohols are produced as a

Olfaction in the Spruce Bark Beetle, Ips typographus [PDF]

, 2011
The bark beetle Ips typographus regularly kills spruce trees in the Palearctic. Spruces are colonized by means of attraction to an aggregation pheromone. Attraction is modulated by anti-attractive volatiles (NHV) from non-host plants.

Some fluorine-containing pheromone analogues.

, 1986
Two analogues of the aphid alarm pheromone (E)-β-farnesene, a trifluorofarnesene and a difluoro-1-norfarnesene, were found to be highly active and were more readily detectable than the parent compound.

Use of Restricted Nursing and a Bovine Appeasing Substance on the Welfare, Growth Performance, and Response to Vaccination of Beef Calves at Weaning

Animal Research and One Health, EarlyView.
The effects of restricted nursing (RN) and the administration of a bovine appeasing substance (BAS) on days −8 and 0 in relation to weaning were evaluated. Both strategies were effective in improving the growth performance of beef calves. Regarding welfare, BAS ‐especially on day 0‐ was more effective than RN.

Alarm pheromone processing in the ant brain: an evolutionary perspective

Frontiers in Behavioral Neuroscience, 2010
Social insects exhibit sophisticated communication by means of pheromones, one example of which is the use of alarm pheromones to alert nestmates for colony defense.

Nasonov pheromone of the honey bee, apis-mellifera l (hymenoptera, apidae) .3. Regulation of pheromone composition and production

, 1981
GC and GC-MS analyses of the multicomponent Nasonov pheromone of the honey bee, and of the air above insects releasing the pheromone, show that constant composition is maintained during release, despite differing volatilities of the components.

Individualised niches: an integrative conceptual framework across behaviour, ecology, and evolution

Biological Reviews, EarlyView.
ABSTRACT Individuals differ. While seemingly trivial, this insight has nevertheless led to paradigm shifts, as three key fields of organismal biology have seen marked changes in key concepts over the past few decades. In animal behaviour, it has become increasingly recognised that behavioural differences among individuals can be stable over time and ...
