Abstract

Using the fluorescence in situ hybridization (FISH), the presence of (TTAGG)n telomeric sequence was detected in the chromosomes of Lethocerus patruelis (Stål, 1854) belonging to the family Belostomatidae (Heteroptera: Nepomorpha). This sequence was exclusively present at the ends of chromosomes in this species. This is the first evidence of the insect-type TTAGG telomeric repeats in Heteroptera.

Keywords: (TTAGG)n telomeric repeat; Belostomatidae; Chromosomes; FISH; Lethocerus patruelis; Nepomorpha; true bugs
