Spatial separation of semiochemical Lurem-TR and entomopathogenic fungi to enhance their compatibility and infectivity in an autoinoculation system for thrips management
Mfuti, D.K. ; Subramanian, S. ; Tol, R.W.H.M. van; Wiegers, G.L. ; Kogel, W.J. de; Niassy, S. ; Plessis, H. du; Ekesi, S. ; Maniania, N.K. - \ 2016
Pest Management Science 72 (2016)1. - ISSN 1526-498X - p. 131 - 139.

BACKGROUND
The effect of spatial separation of the semiochemical Lurem-TR, which has been found to inhibit conidia of entomopathogenic fungi when put together, on the persistence of conidia of Metarhizium brunneum and M. anisopliae was evaluated in the greenhouse and field in order to develop an autodissemination strategy for the management of Megalurothrips sjostedti on cowpea crop. Influence of spatial separation of the semiochemical on thrips attraction and conidial acquisition by thrips from the autoinoculation device was also investigated in the field.
RESULTS
Persistence of conidia of M. brunneum and M. anisopliae increased with distance of separation of Lurem-TR. Direct exposure of fungus without separation from Lurem-TR recorded the lowest conidial germination as compared with the other treatments. Attraction of thrips to the device also varied significantly according to distance between device and semiochemical, with a higher number of thrips attracted when Lurem-TR was placed in a container below the device and at 10 cm distance. There was no significant difference in conidial acquisition between spatial separation treatments of conidia and Lurem-TR. Attraction of other insect pests to the device did not significantly vary between treatments. Positive correlations were found between conidial acquisition and thrips attraction.
CONCLUSION
This study suggests that spatial separation of fungal conidia from Lurem-TR in an autoinoculation device could provide a low-cost strategy for effective management of thrips in grain legume cropping systems.

Temporal, Affective, and Embodied Characteristics of Taste Experiences: A Framework for Design
Obrist, M. ; Comber, R. ; Subramanian, S. ; Piqueras Fiszman, B. ; Velasco, C. ; Spence, C. - \ 2014
In: Proceedings of the SIGCHI Conference on Human Factors in Computing Systems. - - p. 2853 - 2862.
We present rich descriptions of taste experience through an analysis of the diachronic and synchronic experiences of each of the five basic taste qualities: sweet, sour, salt, bitter, and umami. Our findings, based on a combination of user experience evaluation techniques highlight three main themes: temporality, affective reactions, and embodiment. We present the taste characteristics as a framework for design and discuss each taste in order to elucidate the design qualities of individual taste experiences. These findings add a semantic understanding of taste experiences, their temporality enhanced through descriptions of the affective reactions and embodiment that the five basic tastes elicit. These findings are discussed on the basis of established psychological and behavioral phenomena, highlighting the potential for taste-enhanced design.
Water, Politics and Development: Framing a Political Sociology of Water Resources Management
Mollinga, P.P. ; Bhat, A. ; Cleaver, F. ; Meinzen-Dick, R. ; Molle, F. ; Neef, A. ; Subramanian, S. ; Wester, P. - \ 2008
Water Alternatives 1 (2008)1. - ISSN 1965-0175 - p. 7 - 23.
EDITORIAL PREAMBLE: The first issue of Water Alternatives presents a set of papers that investigates the inherently political nature of water resources management. A Water, Politics and Development initiative was started at ZEF (Center for Development Research, Bonn, Germany) in 2004/2005 in the context of a national-level discussion on the role of social science in global (environmental) change research. In April 2005 a roundtable workshop with this title was held at ZEF, sponsored by the DFG (Deutsche Forschungsgemeinschaft/German Research Foundation) and supported by the NKGCF (Nationales Komitee für Global Change Forschung/German National Committee on Global Change Research), aiming to design a research programme in the German context. In 2006 it was decided to design a publication project on a broader, European and international basis. The Irrigation and Water Engineering Group at Wageningen University, the Netherlands joined as a co-organiser and co-sponsor. The collection of papers published in this issue of Water Alternatives is one of the products of the publication project. As part of the initiative a session on Water, Politics and Development was organised at the Stockholm World Water Week in August 2007, where most of the papers in this collection were presented and discussed. Through this publication, the Water, Politics and Development initiative links up with other initiatives simultaneously ongoing, for instance the 'Water governance ¿ challenging the consensus' project of the Bradford Centre for International Development at Bradford University, UK. At this point in time, the initiative has formulated its thrust as 'framing a political sociology of water resources management'. This, no doubt, is an ambitious project, methodologically, theoretically as well as practically. Through the compilation of this collection we have started to explore whether and how such an endeavour might make sense. The participants in the initiative think it does, are quite excited about it, and are committed to pursue it further. To succeed the project has to be a collective project, of a much larger community than the present contributors. All readers are invited to comment on sense, purpose and content of this endeavour to profile and strengthen critical and public sociologies of water resources management.
