We have found the following differences in the male meiosis among three triatomine species: (1) The three largest autosomal bivalents ofTriatoma infestans are heterochromatic.Rhodnius prolixus has two autosomal bivalents with heterochromatic blocks.Triatoma rubrovaria does not show any heteropycnotic autosomes. (2) Sex chromosomes inT. infestans form a chromocenter. At early prophase terminal associations are seen between sex chromosomes inT. rubrovaria, and they maintain a close association… CONTINUE READING
