Heteroptera are the most important group of insects of economic importance, becausemost of them feed on crops or stored grains used for human consumption. The cytogeneticanalyses showed that Antiteuchus tripterus has a compound lobe (5/6), which could be involved in the formation of the harlequin lobe, giving evidence that evolutionary pressureexisted for the maintenance of this lobe in this species, which demonstrates the importance of
this lobe for some species. All species analyzed have XY sexual chromosome systems and achromosome complement of 2n = 14 chromosomes. Furthermore, the analyses of nucleolarbehavior showed that there are different metabolic activities in lobes 4, 5, and 6 of A. tripterusand in the species without the harlequin lobe, such as Platycarenus umbractulatus, that alsohad differential marking of lobe 5, which could indicate the formation of non-fertilizing sperm.
