I plan to record the electrophysiological responses of receptor cells within olfactory sensilla on the antenna of female Lutzomyia sandflies to a range of odours involved in the attraction of sandflies to hosts and to sex pheromone components from males.
Then it is planned to test the behavioral responses of Lutzomyia in a wind tunnel to the identified chemostimuli and to test the hypothesis that host odours and pheromone components can act together in modifying the behaviors of these vectors of disease.

Lutzomyia vectors for cutaneous leishmaniasis in Southern Brazil: ecological niche models, predicted geographic distributions, and climate change effects.
Geographic and ecological distributions of three Lutzomyia sand flies that are cutaneous leishmaniasis vectors in South America were analyzed using ecological niche modelling.
Projections of potential geographic distributions across scenarios of global climate change suggested that only Lutzomyia whitmani is likely to be experiencing dramatic improvements in conditions in south-eastern Brazil, where cutaneous leishmaniasis appears to be re-emerging; Lutzomyia intermedia and Lutzomyia migonei may be seeing more subtle improvements in climatic conditions, but the implications are not straightforward.

It is interesting to note the amount of variation that exists in the number of members of the different protein families found in the four sandflies (Table 3).
This lack of cross-reactivity is possibly due to the low degree of similarities found in the Lutzomyia and Phlebotomus salivary proteins, as reported in the present work, and to the lack of recognition to specific molecules present exclusively in the different genera.
