Hexapod Origins: Monophyletic or Paraphyletic?
Recent morphological and molecular evidence has changed interpretations of arthropod phylogeny and evolution. Here we compare complete mitochondrial genomes to show that Collembola, a wingless groupExpand

Population structure and colonization history of the olive fly, Bactrocera oleae (Diptera, Tephritidae)
The olive fly, Bactrocera oleae, is the major pest of olives in most commercial olive‐growing regions worldwide. The species is abundant in the Mediterranean basin and has been introduced recentlyExpand

Domestication of olive fly through a multi-regional host shift to cultivated olives: comparative dating using complete mitochondrial genomes.
The evolutionary history of the olive fly, Bactrocera oleae, was reconstructed in a phylogenetic and coalescent framework using full mitochondrial genome data from 21 individuals covering the entireExpand

Wolbachia-induced delay of paternal chromatin condensation does not prevent maternal chromosomes from entering anaphase in incompatible crosses of Drosophila simulans.
The behavior of parental chromosomes during the first mitosis of Drosophila simulans zygotes obtained from unidirectional incompatible crosses is described and it is demonstrated that theExpand

The mitochondrial genome of the olive fly Bactrocera oleae: two haplotypes from distant geographical locations
The complete sequence of the olive fly (Bactrocera oleae) mitochondrial genome has been determined. Two independent haplotypes, from flies of distant geographical origin (Italy and Portugal) wereExpand

The complete mitochondrial DNA sequence of the basal hexapod Tetrodontophora bielanensis: evidence for heteroplasmy and tRNA translocations.
We present the complete 15,455-nt mitochondrial DNA sequence of the springtail Tetrodontophora bielanensis (Arthropoda, Hexapoda, Collembola). The gene content is typical of most metazoans, with 13Expand

Fine structure of the spermatheca of Apis mellifera
Abstract The ultrastructure of the receptacle and duct of the spermatheca of non-fertilized Apis mellifera, of bees a few days after fertilization and of 2- to 3-year-old bees has been investigated.Expand

Microtubular diversity in insect spermatozoa: Results obtained with a new fixative
Abstract The architecture of the tail axoneme of spermatozoa from 49 insect species representing 20 insect orders has been examined. Whereas the microtubular walls of the nine doublet tubules and theExpand

Sperm structure of Mecoptera and Siphonaptera (Insecta) and the phylogenetic position of Boreus hyemalis
Sperm ultrastructure has been studied in three species of the taxa Mecoptera and Siphonaptera. The spermatozoon of the scorpion fly Panorpa germanica shows an apical bilayered acrosome, a helicoidalExpand
