The nature of alarm communication in Constrictotermes cyphergaster (Blattodea: Termitoidea: Termitidae): the integration of chemical and vibroacoustic signals

Biology Open, 2015
Alarm signalling is of paramount importance to communication in all social insects. In termites, vibroacoustic and chemical alarm signalling are bound to operate synergistically but have never been studied simultaneously in a single species.

A push-pull strategy to control the western flower thrips, Frankliniella occidentalis, using alarm and aggregation pheromones.

PLoS ONE, 2023
Since the first report in 1993 in Korea, the western flower thrips, Frankliniella occidentalis, has been found in various crops throughout the country. Although more than 20 different chemical insecticides are registered to control this insect pest, its ...

Identification of two odorant receptors tuned to alarm pheromone compounds in the honey bee Apis mellifera. [PDF]

Commun Biol
Being social insects, honey bees use an array of pheromones to facilitate intraspecific communication, ensuring colony cohesion in a wide range of contexts. The honey bee represents an attractive model for studying the neurobiological basis of pheromonal

Density dependence of the alarm pheromone effect in pea aphids, Acyrthosiphon pisum (Sternorrhyncha: Aphididae)

European Journal of Entomology, 2007
The aphid alarm pheromone is known to trigger wing induction in pea aphids (Acyrthosiphon pisum). In reaction to alarm pheromone, aphids drop off the plant or walk away.

The role of alarm pheromone in honey bee (Apis mellifera L.) colonies [PDF]

Journal of Central European Agriculture
The alarm pheromone of honey bees represents a crucial part of their social system and defense mechanisms. When confronted with a threat, worker bees release this chemical signal to alert other members of the community to the danger.

Honey Bees Modulate Their Olfactory Learning in the Presence of Hornet Predators and Alarm Component. [PDF]

PLoS ONE, 2016
In Southeast Asia the native honey bee species Apis cerana is often attacked by hornets (Vespa velutina), mainly in the period from April to November.

Two odorant-binding proteins mediate the behavioural response of aphids to the alarm pheromone (E)-ß-farnesene and structural analogues. [PDF]

PLoS ONE, 2012
BackgroundAphids are agricultural pests of great economical interest. Alternatives to insecticides, using semiochemicals, are of difficult applications.

Symmetry breaking on density in escaping ants: experiment and alarm pheromone model. [PDF]

PLoS One, 2014
The symmetry breaking observed in nature is fascinating. This symmetry breaking is observed in both human crowds and ant colonies. In such cases, when escaping from a closed space with two symmetrically located exits, one exit is used more often than the

Shaft vibration alarm strategy for motor-driven centrifugal compressor set based on single-node ant colony algorithm

You-qi chuyun, 2022
The motor-driven centrifugal compressor set may have some faults that can cause abnormal change in direct amplitude of shaft vibration during the steady-state operation. However, such a change does not necessarily trigger the alarm, so it is difficult to

Evolutionarily entrenched odorant receptors for (<i>E</i>)-β-farnesene signaling in Aphidinae aphids. [PDF]

iScience
Summary: Alarm pheromones are crucial for the survival of social insects, enabling coordinated escape from predators. Their evolution has co-evolved with the development of olfactory recognition systems, suggesting specific molecular mechanisms underlie ...
