Bed bug cytogenetics: karyotype, sex chromosome system, FISH mapping of 18S rDNA, and male meiosis in Cimex lectularius Linnaeus, 1758 (Heteroptera: Cimicidae)
A cytogenetic study of the common bed bug Cimex lectularius Linnaeus, 1758 is performed using both classical (Schiff-Giemsa and AgNO 3 -staining) and mo- lecular (base-specifi c DAPI/CMA 3 fl uorochromes and FISH with an 18S rDNA probe).
Patterns of chromosome banding in four nabid species (Heteroptera, Cimicomorpha, Nabidae) with high chromosome number karyotypes.
New information on the genome organization and new cytological markers useful for a better insight into karyotype evolution of nabid species are provided.
Molecular phylogeny of the Mediterranean species of Philaenus (Hemiptera: Auchenorrhyncha: Aphrophoridae) using mitochondrial and nuclear DNA sequences

The phylogenies of all eight European species of Philaenus were estimated from cytochrome oxidase subunit I, cytochrome B and internal transcribed spacer 2 (ITS2) fragments of DNA using phylogenetic…
Parthenogenesis in Hexapoda: holometabolous insects
Data on parthenogenesis across Holometabola as well as other insects are summarized and discussed and the main parthenogenetic taxa and modes ofparthenogenesis are listed.
Karyotypes, male meiosis and comparative FISH mapping of 18S ribosomal DNA and telomeric (TTAGG) n repeat in eight species of true bugs (Hemiptera, Heteroptera)
The insect consensus telomeric pentanucleotide (TTAGG)n was demonstrated to be absent in all the species studied in this respect, supporting the hypothesis that this motif was lost in early evolution of the Heteroptera and secondarily replaced with another motif (yet unknown) or the alternative telomerase-independent mechanisms of telomere maintenance.
Telomere structure in insects: A review
The Mediterranean: Area of origin of polymorphism and speciation in the spittlebug Philaenus (Hemiptera, Aphrophoridae)
It is shown that dorsal colour polymorphism in the spittlebug Philaenus spumarius is more complicated than reported earlier and its polymorphism probably preceded speciation also in the Mediterranean as polymorphism is common in other genera occurring in that region.
The first finding of (TTAGG)n telomeric repeat in chromosomes of true bugs (Heteroptera, Belostomatidae)
This work has detected the first evidence of the insect-type TTAGG telomeric repeats in Heteroptera through fluorescence in situ hybridization.
Parthenogenesis in Hexapoda: Entognatha and non‐holometabolous insects
It is shown that conclusions about the reproductive mode often lack solid evidence and sometimes inefficiently demonstrate how parthenogenesis is maintained in corresponding groups, as in the case of hexapods.
Holocentric chromosomes in meiosis. I. Restriction of the number of chiasmata in bivalents
The elimination of the cells carrying bivalents with more than two chiasmata creates a strong selection against the formation of more than one chiasma loops in holocentric bivalENTs.
