The expression patterns of two muscle‐specific actin genes were studied in the yellow fever mosquito, Aedes aegypti . The coding sequence of AeAct‐2 exhibits between 82 and 85% similarity with coding sequences of the Drosophila melanogaster and predicted Anopheles gambiae actin genes. The transcription of the AeAct‐2 gene was differentially regulated during developmental stages with higher levels of expression in larvae and lower levels in pupae and adults. The AeAct‐2 gene is mainly expressed in the head and body wall tissues. Transcripts of the AeAct‐3 gene are not detectable in larvae until late 4th instar and the level increased in male pupae and early male adults. The main site of expression of the AeAct‐3 gene was the thoracic tissue. Thus, AeAct‐3 is the first reported male‐specific actin gene in mosquitoes.
