Abstract:
<p>The notion that humans have specialized chemicals used for communication between conspecifics, so-called pheromones, has attracted much attention and discussion. This thesis demonstrates in four separate studies that a human endogenous steroidal compound that is abundant in male sweat, androstadienone, affects women in several ways that differ to that of common odors. Specifically, androstadienone was found in Study I to have unique psychophysical characteristics in that the sensitivity distribution of the odor is bimodal with a smaller subpopulation consisting of highly sensitive individua

Abstract:
GC-MS analysis of Camponotus floridanus revealed that queens and workers differ significantly in their cuticular hyrdrocarbons (CHC's) and surface compounds of their eggs. The CHC profiles comprised a complex mixture of straight and branched alkanes. Bioassays showed that the hydrocarbons on queens and queen eggs carry a signal that prevents workers from laying eggs and protects queen eggs from worker policing. GC-MS analysis also showed that the CHC's of C.jloridanus queens and workers and C. tortuganus workers differ between colonies. Synthesis of queen specific compounds was carried out in

Abstract:
The hypothesis that midge sex pheromones could be chemically more diverse in structure than previously thought was tested in the context of four midge species of importance to UK horticulture: pear leaf midge, Dasineura pyri; pear midge, Contarinia pyrivora; blackcurrant midge, D. tetensi; and blackberry midge, D. plicatrix. The major component of the pheromone of D. pyri was identified as (2R, 13R, 8Z)-2, 13-diacetoxy-8-heptadecene. Four isomers were separated by HPLC and in field tests the first eluting isomer only was attractive to male midges. Analysis of volatile collections from female C

Abstract:
Pacifastacus leniusculus and Procambarus clarkii are highly invasive freshwater crayfish and are having detrimental impacts on native species and habitats throughout Europe. The application of pheromone baits have been proposed as a way of increasing trap efficiency for population control, however the chemical identity of crayfish pheromones is unknown. An incomplete understanding of chemical communication has delayed progress in the development of appropriate bioassays. This thesis therefore focused on researching the natural context of chemical signalling by crayfish, including signal delive

Abstract:
Maternal behavior in rodents is dependent, at least in part, on prolactin acting in the brain. Pheromones carried by male mouse major urinary proteins lower serum prolactin levels in female mice. Therefore, we hypothesized that virgin female C57BL/6J mice housed in split cages, where they had pheromonal but not physical contact with a male, would show suppressed maternal behavior. Contrary to our hypothesis, we found split-cage housed females were significantly faster to retrieve 3 foster pups on the first and second day of maternal behavior testing compared to mice housed in individual cages.

Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) is an invasive worldwide pest of many agricultural, horticultural and ornamental crops. They are difficult to control because of their small size and high resistance to chemical insecticides. The aggregation pheromone of this species is currently used for monitoring, but the full potential for use of this and other pheromones has not yet been explored. Two male-specific headspace volatiles have been previously identified: neryl (S)-2-methylbutanoate which acts as an aggregation pheromone and (R)-lavandulyl acetate, for which the r

Abstract:
Fishes use pheromones (intraspecific chemical messages) to coordinate reproduction, migration and social interactions but their identity is rarely known. In the Mozambique tilapia (Oreochromis mossambicus), a social, lek-breeding cichlid, reproduction and male aggression are mediated through urinary cues released by dominant males. The main goal of this thesis was the chemical identification of such pheromones and establishment of their function(s). Two steroid glucuronates (5β-pregnane-3α,17,20β-triol 3-glucuronate and its 20α-epimer) were identified as the most potent odorants in male urine.

Abstract:
The aim of this project was to develop a general theory of stigmergy and a software design pattern to build collaborative websites. Stigmergy is a biological term used when describing some insect swarm-behaviour where 'food gathering' and 'nest building' activities demonstrate the emergence of self-organised societies achieved without an apparent management structure. The results of the project are an abstract model of stigmergy and a software design pattern for building Web 2.0 components exploiting this self-organizing phenomenon.

This thesis describes a number of synthetic approaches for obtaining chiral, enantiomerically pure natural products, in particular some semiochemicals. This has been accomplished by using various strategies; by starting from compounds from the chiral pool, by using chiral auxiliaries, via enzymatic resolutions or by chemical asymmetric synthesis. Hence, the sexual pheromone of Microdiprion pallipes, a propanoate ester of one or several isomers of 3,7,11-trimethyltridecan-2-ol, was synthesised, both as a mixture of all isomers and as the sixteen pure, individual stereoisomers.

Abstract:
The chemical ecology of Heteroptera insects is determined by a wide array of chemical signals (semiochemicals) that drive their behavior at intra- and inter-specific level. Intraspecific semiochemicals are called pheromones, interspecific chemicals are named allelochemicals. In the case of stink bugs, sex-pheromones and aggregation pheromone are produced by adult males. Furthermore, phytophagous stink bugs exploit chemical cues emitted from plants to find a suitable food and oviposition source.
