Journal ArticleDOI
TTAGG Telomeric Repeats in Chromosomes of Some Insects and Other Arthropods
TL;DR: 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.
Journal ArticleDOI
Sex chromosomes and sex determination in Lepidoptera.
TL;DR: The sex chromosome system is being exploited in economically important species and special strains have been devised for mass rearing of male-only broods in the silkworm for higher silk production and in pest species for the release of sterile males in pest management programs.
Journal ArticleDOI
Evolutionary dynamics of rDNA clusters on chromosomes of moths and butterflies (Lepidoptera)
TL;DR: E ectopic recombination is proposed, i.e., homologous recombination between repetitive sequences of non-homologous chromosomes, as a primary motive force in rDNA repatterning.
Journal ArticleDOI
Neo-sex chromosomes and adaptive potential in tortricid pests

TL;DR: It is suggested that this Z–autosome fusion brought two major genes conferring insecticide resistance and clusters of genes involved in detoxification of plant secondary metabolites under sex-linked inheritance to the tortricid moths and thus contributed to their radiation and subsequent speciation.
Journal ArticleDOI
Phenotypic grouping of 141 BmNPVs lacking viral gene sequences.
TL;DR: In a subsequent analysis of the properties needed for infection using a marker gene, egfp (enhanced green fluorescent protein gene), inserted into the polyhedrin locus, the knockout viruses (KOVs) were subdivided into four phenotypic types, A to D.
