Project description:Many arthropod pests of humans and other animals select their preferred hosts by recognising volatile odour compounds contained in the hosts' 'volatilome'. Although there is prolific literature on chemical emissions from humans, published data on volatiles and vector attraction in other species are more sporadic. Despite several decades since the identification of a small number of critical volatiles underpinning specific host-vector relationships, synthetic chemicals or mixtures still largely fail to reproduce the attractiveness of natural hosts to their disease vectors. This review documents allelochemicals from non-human terrestrial animals and considers where challenges in collection and analysis have left shortfalls in animal volatilome research. A total of 1287 volatile organic compounds were identified from 141 species. Despite comparable diversity of entities in each compound class, no specific chemical is ubiquitous in all species reviewed, and over half are reported as unique to a single species. This review provides a rationale for future enquiries by highlighting research gaps, such as disregard for the contribution of breath volatiles to the whole animal volatilome and evaluating the role of allomones as vector deterrents. New opportunities to improve vector surveillance and disrupt disease transmission may be unveiled by understanding the host-associated stimuli that drive vector-host interactions.
Project description:In this study, we developed and applied a paleoproteomics approach to study inclusions of fossil arthropod parasitiformes in two Burmese amber (Cretaceous, ca. 124 - 99 mya) pieces. The results supported the identification of Cornupalpatum sp. and the first report of fossil Holothyrida, Neothyridae at both morphological and molecular levels. Identified proteins were analyzed to evaluate evolutionary trees with possible functional implications in biomedicine. Actin proteins were identified in both amber inclusions and may belong to Neothyridae and Cornupalpatum sp., respectively.
