Abstract

The use of cytogenetic tools, molecular markers and ultrastructural have been very useful in the identification and analysis of genetic diversity for different taxonomic groups. The Heteroptera suborder stands out for presenting wide range and are extremely important for public health (vectors of Chagas disease) and agriculture (pest various vegetables: for example, soy, corn, sorghum, rubber). Moreover, it presents a wide diversity of species and genetics, and some peculiarities in their cytogenetic aspects. Despite this wide range, more depth cytogenetic tools (fluorescent in situ hybridization) and ultrastructural features observed during spermatogenesis have not been frequently used to characterize this suborder. On the other hand, the use of these markers in other body groups has been an important tool being useful in karyotype diversity studies, genomic organization, taxonomy, and systematic evolution. This project aims to continue gathering information on the testicles (shape, color sheath number of wolves and morphology of the testes), chromosome complement, chromosomal sex system, structure and ultrastructure of spermatogenesis and citomolecular. Therefore, further study is extremely important for the further development of cytogenetic analysis, structural and ultrastructural from new methodologies that may contribute to the development of the studies of the species, in addition to systematic and evolutionary.
