We identified GPCRs for neurohormones and opsins in Rhodnius prolixus genome sequence.
Thirty-seven of the identified proteins had matching EST evidence in R. prolixus CNS.
ESTs from GPCRs were identified in Triatoma spp.
We describe the transcriptome of R. prolixus central nervous system.
The study reveals a high degree of conservation in the neuroendocrine system in triatomines.
