Developing photoreceptor-based models of visual attraction in riverine tsetse, for use in the engineering of more-attractive polyester fabrics for control devices.

摘要: Riverine tsetse transmit the parasites that cause most prevalent form of human African trypanosomiasis, Gambian HAT. In response to imperative for cheap and efficient control, insecticide-treated 'tiny targets' have been developed through refinement attractants based on blue fabric panels. However, modern polyesters used this purpose attract many less than traditional phthalogen cottons. Therefore, colour engineering improved attractiveness has great potential tiny target development. Because flies markedly different photoreceptor spectral sensitivities from humans, responses these photoreceptors provide inputs their visually guided behaviours, it is essential polyester be by fly photoreceptor-based explanations attraction. To end, attraction differently coloured fabrics was recently modelled using calculated excitations elicited in a generic set as predictors. electrophysiological data indicate modified versus pattern, processing within segregated achromatic chromatic channels long hypothesised. Thus, I constructed models explaining G. f. fuscipes targets recorded previously published investigation, under differing assumptions about organisation visual processing. Models separating into explained better earlier combining weighted single mechanism, regardless assumed. common principles were evident across complete examined, consistent with work. Tools calculation are available paper, ways which can colorimetric values more-attractively discussed.
