Description of the pre-reductional sex chromosome during male meiosis of Pachylis laticornis (Heteroptera: Coreidae)
(Genetics And Molecular Research, 2016-01-01) [Artigo]
In Heteroptera, the division of sex chromosomes is well defined as post-reductional for most of species, i. e., the first meiotic division is equational and the second is reductional. However, in some species pre-reductional ...
Karyotype and spermatogenesis in Triatoma lenti (Hemiptera: Triatominae), a potential Chagas vector
(Genetics and Molecular Research, 2012-01-01) [Artigo]
All species of Triatominae are susceptible to infection by Trypanosoma cruzi (Kinetoplastida: Trypanosomatidae) and consequently, potential insect vectors of Chagas disease. Currently, there are 140 known species of ...
Meiotic chromosomes and nucleolar behavior in testicular cells of the grassland spittlebugs Deois flavopicta, Mahanarva fimbriolata and Notozulia entreriana (Hemiptera, Auchenorrhyncha)
(Genetics and Molecular Biology, 2010-01-01) [Artigo]
Spittlebugs annually infest pastures and cause severe damage, representing a serious problem for the tropical American beef cattle industry. Spittlebugs are an important biotic constraint to forage production and there is ...
Origin and distribution of AT-rich repetitive DNA families in Triatoma infestans (Heteroptera)
(Infection, Genetics and Evolution, 2014-04-01) [Artigo]
Triatoma infestans, one of the most important vectors of Trypanosoma cruzi, is very interesting model, because it shows large interpopulation variation in the amount and distribution of heterochromatin. This polymorphism ...
The conservation of number and location of 18S sites indicates the relative stability of rDNA in species of Pentatomomorpha (Heteroptera)
(Genome, 2013-07-01) [Artigo]
Fluorescent in situ hybridization (FISH) with rDNA probes has been used for comparative cytogenetics studies in different groups of organisms. Although heteropterans are a large suborder within Hemiptera, studies using ...
