Interaction of visual and olfactory cues in the aggregation behaviour of the haematophagous bug Triatoma infestans

We analysed how the assembling behaviour of Triatoma infestans is modulated by the convergence of chemical cues released by their faeces and the spectral quality of the light associated with refuges. Secondinstar larvae were confronted with refuges associated with a visual stimulus (either blue, gre...
