TTAGG Telomeric Repeats in Chromosomes of Some Insects and Other Arthropods
TLDR
The results, which confirm and extend earlier observations, suggest that (TTAGG)n was a phylogenetically ancestral telomere motif in the insect lineage but was lost independently in different groups, being replaced probably by other telomeres motifs. Expand
Phylogenetic distribution of TTAGG telomeric repeats in insects.
TLDR
The repeated losses of TTAGG in different branches of the insect phylogenetic tree and, in particular, in the most successful lineage of insect evolution, the Endopterygota, suggest a backup mechanism in the genome of insects that enabled them frequent evolutionary changes in telomere composition.

A Mite Species That Consists Entirely of Haploid Females
TLDR
This work used fluorescence microscopy and variation at nine microsatellite loci to show that the false spider mite, Brevipalpus phoenicis, consists of haploid female parthenogens, and shows that this reproductive anomaly is caused by infection by an undescribed endosymbiotic bacterium, which results in feminization of haploids genetic males. Expand
Genomic evidence for divergence with gene flow in host races of the larch budmoth
TLDR
It is concluded that the variance of the level of sympatric divergence among chromosomes is the footprint of divergent selection acting on a few linkage groups, combined with appreciable gene flow that homogenizes between‐race variation at the remaining linkage groups. Expand
Inherited Sterility in Insects
TLDR
F1 sterile progeny produced in the field enhance the efficacy of released partially sterile males, and improve compatibility with other pest control strategies, and can be used to increase the production of natural enemies, and to study the potential host and geographical ranges of exotic lepidopteran pests. Expand
Evolutionary dynamics of rDNA clusters on chromosomes of moths and butterflies (Lepidoptera)
TLDR
E ectopic recombination is proposed, i.e., homologous recombination between repetitive sequences of non-homologous chromosomes, as a primary motive force in rDNA repatterning. Expand
The telomere repeat motif of basal Metazoa
TLDR
The results show that the ‘vertebrate’ telomere motif (TTAGGG)n is present in all basal metazoan groups, i.e. sponges, Cnidaria, Ctenophora, and Placozoa, and also in the unicellular metazoa sister group, the Choanozoa, and can be considered the ancestral telomeres repeat motif of Metazoa. Expand
Repeated Losses of TTAGG Telomere Repeats in Evolution of Beetles (Coleoptera)
TLDR
It is concluded that the telomerase-dependent (TTAGG)n motif had been repeatedly lost in different phylogenetic branches of Coleoptera and probably replaced with another mechanism of telomere elongation. Expand
The evolutionary origin of insect telomeric repeats, (TTAGG)n
TLDR
Analysis of polymerase dynamics in living Chinese hamster ovary cells using an established line that expresses the largest (catalytic) subunit of the polymerase (RPB1) tagged with the green fluorescent protein (GFP) shows this tagged polymerase to be fully functional. Expand
Improvement of the sterile insect technique for codling moth Cydia pomonella (Linnaeus) (Lepidoptera Tortricidae) to facilitate expansion of field application
TLDR
The sterile insect technique (SIT) and its derivative, inherited sterility (IS), are, together with mating disruption and granulosis virus, among the options that offer great potential as cost‐effective additions to available control tactics for integration in area‐wide integrated pest‐management approaches.
