Abstract:
Haemopis marmorata, the green horse leech, is carnivorous and readily eats earthworms. Using a Y-maze with flowing water, we show that specimens of H. marmorata are attracted to live earthworms. Ablating the dorsal lip, the presumed site of the chemoreceptors that this species uses in prey search, disrupts the ability of the leeches to find the earthworms in the Y-maze. Earthworm wash, a preparation of the collagen coating of earthworm skin, shock-induced earthworm secretion, mammalian blood and a salt­arginine mixture are not attractive to the green horse leech.

Abstract:
The round goby (Neogobius melanostomus) is an invasive fish in the Laurentian Great Lakes and beyond. Pheromones appear to be important for their reproductive success, as females are attracted to water in which reproductive males have resided (“conditioned water”). Previous investigation has shown conjugated and unconjugated forms of 3α-hydroxy-5β-androstane-11,17-dione (11-oxo-etiocholanolone; 11-O-ETIO) are released in the urine of these males. The goal of this study was to determine if the urine of reproductive males and fractionated extracts attract females. We found that reproductively ac

Background. Attractive toxic sugar bait (ATSB), based on “attract and kill” approach, is a novel and promising strategy for mosquito control. Formulation of an attractive sugar bait (ASB) solution by selecting an efficient olfaction stimulant and preparation of an optimized sugar-attractant dosage is a significant component for the success of the approach. Methods. Current study evaluated relative potential of nine ASBs, formulated by combination of sugar and fresh fruit juices (guava, mango, muskmelon, orange, papaya, pineapple, plum, sweet lemon, and watermelon) in attracting Aedes aegypti a

Abstract:
Deep-sea species endemic to hydrothermal vents face the critical challenge of detecting active sites in a vast environment devoid of sunlight. This certainly requires specific sensory abilities, among which olfaction could be a relevant sensory modality, since chemical compounds in hydrothermal fluids or food odors could potentially serve as orientation cues. The temperature of the vent fluid might also be used for locating vent sites. The objective of this study is to observe the following key behaviors of olfaction in hydrothermal shrimp, which could provide an insight into their olfactory c

Patterns of bat activity and mortalities at wind energy facilities suggest that bats are attracted to wind turbines based on bat behavioral responses to wind turbines. For example, current monitoring efforts suggest that bat activity increases post-wind turbine construction, with bats making multiple passes near wind turbines. We separated the attraction hypothesis into five previously proposed explanations of bat interactions at or near wind turbines, including attraction based on noise, roost sites, foraging and water, mating behavior, and lights, and one new hypothesis regarding olfaction,

Abstract:
Olfaction is a common sensory mode of communication in much of the Vertebrata, although its use by adult frogs remains poorly studied. Being part of an open signalling system, odour cues can be exploited by ‘eavesdropping’ predators that hunt by smell, making association with odour a high-risk behaviour for prey. Here, we show that adult great barred frogs ( Mixophes fasciolatus ) are highly attracted to odour cues of conspecifics and those of sympatric striped marsh frogs ( Limnodynastes peronii ). This attraction decreased significantly with the addition of odours of a scent-hunting predator

It was long believed that humans were unable to utilise the odours of conspecifics to co-ordinate social interactions in ways in which other species appear to be capable. However, a surge in interest in human social olfaction has recently challenged this view. The numerous studies conducted in this area have found that multiple state and trait related cues can be detected in body odour. Furthermore, many studies indicate that women are often more sensitive to these cues, and that sensitivity can be associated with fertility, findings that are consistent with sex differences in reproductive eff

Abstract:
Abstract The chemical senses—taste and smell—are the oldest animal senses. They are characterized by a multidimensional and diverse stimulus space, consisting of many molecules that cannot be classified along any narrow set of dimensions. In the case of the olfactory system, animals detect low molecular weight volatile chemicals (i.e. odorants) with the help of specialized olfactory sensory neurons that express one or a few ligand-binding odorant receptor proteins. Animals cope with the problem of recognizing an extremely large number of different odorants by programming a very large number of functionally different olfactory neurons. Odours activate these neurons and generate characteristic activity patterns across the neuron population, which are relayed to second-order olfactory neurons. The entire available raw information about the animal’s olfactory environment is present in these patterns; however, olfactory information is further processed before it is relayed to higher-order brain centres. Drosophila melanogaster provides an attractive model organism for studying olfaction, as it allows genetic, molecular, and physiological analyses. In recent years, immense progress has been achieved in understanding the olfactory neuronal circuits that underlie the coding and processing of odours in Drosophila. Here, the chapter reviews our present state of knowledge regarding the anatomical architecture of the fly’s olfactory system as well as giving recent insights into the coding strategies of the different neuronal populations involved.
