System performance in multi-agent resource allocation systems can often improve if individual agents reduce their activity. Agents in such systems need a way to modulate their individual behavior in the light of the system’s state, preferably in a way that does not require centralized control. We illustrate the problem of hyperactive agents in two domains related to resource allocation. We desc...

Wireless sensor network (WSN) is a new research area of computer science and technology and has a wide application future,more and more attention. It will be much market in application of military, health, home, environment, etc. In WSN, sensor devices have limited supply of energy. The sensor death due to dissipating battery energy is one of the fundamental design issues in WSNs. Hence, energy...

Pheromone-based multiagent interaction has received a growing attention in the past few years. Still, so far, the number of deployed systems exploiting pheromones for coordinating activities of distributed agents/robots situated in physical environments has been very limited. In this context, this paper presents a real-world, lowcost and general-purpose, implementation of pheromone interaction,...

Musth is an important male phenomenon affecting many aspects of elephant society including reproduction. During musth, the temporal gland secretions (as well as the urine and breath) of adult male Asian elephants (Elephas maximus) discharge a variety of malodorous compounds together with the bicyclic ketal, frontalin. In contrast, teenage male elephants in musth release a sweet-smelling exudate...

Moths depend on olfactory cues such as sex pheromones to find and recognize mating partners. Pheromone receptors (PRs) and Pheromone binding proteins (PBPs) are thought to be associated with olfactory signal transduction of pheromonal compounds in peripheral olfactory reception. Here six candidate pheromone receptor genes in the diamondback moth, Plutella xyllostella were identified and cloned....

The influence of trap placement on catches of codling moth, Cydia pomonella L., was examined in a series of studies conducted in orchards treated with Isomate-C Plus sex pheromone dispensers. Mark-recapture tests with sterilized moths released along the interface of pairs of treated and untreated apple and pear plots found that significantly more male but not female moths were recaptured on int...

Keywords: cue mating system parasitoid sex pheromone signal Venturia canescens wind tunnel In many animals, mating takes place after natal dispersal. Consequently, use of reliable information is required to increase the probability of encounters between the sexes. Most of the studies on mate finding in parasitoid insects have focused on the role of a single information source: a sex pheromone. ...

Our understanding of insect chemical communication including pheromone identification, synthesis, and their role in behavior has advanced tremendously over the last half-century. However, endocrine regulation of pheromone biosynthesis has progressed slowly due to the complexity of direct and/or indirect hormonal activation of the biosynthetic cascades resulting in insect pheromones. Over 20 yea...

Insect pheromones, especially sex pheromones, have successfully contributed to pest management programs around the world since the 1970s. In this chapter I examine some of the ways in which pheromones have been used in insect management programs and introduce some of the real-world issues that have promoted, and hindered, their adoption for use against different species. These include biologica...
