A comparison of parthenogenetic and sexual embryogenesis of the pea aphid Acyrthosiphon pisum (Hemiptera: Aphidoidea).
TLDR
The pea aphid is a useful model system for examining how a single genome has evolved to allow divergent modes of development and the function of the serosa has diverged greatly in the two embryos.

TLDR
It is indicated that cockroaches are a monophyletic group, whose sister group is Mantoidea, and the phylogeny inferred here does not support a close relationship between C. punctulatus and M. darwiniensis.
Nitrogen recycling and nutritional provisioning by Blattabacterium, the cockroach endosymbiont
TLDR
The ancient association with Blattabacterium has allowed cockroaches to subsist successfully on nitrogen-poor diets and to exploit nitrogenous wastes, capabilities that are critical to the ecological range and global distribution of cockroach species.
Taxonomy and Phylogeny of Termites
TLDR
The present classification, as used since 1972, has been moderately stable but suffers from a lack of good defining synapomorphies for several groups and a rearrangement of taxa is desirable; recent advances in molecular techniques, cladistic analyses and increased cooperation among scientists employing disparate character sets suggest a resolution of these problems.
Developmental Origin and Evolution of Bacteriocytes in the Aphid–Buchnera Symbiosis
TLDR
The development and evolution of aphid bacteriocytes, the host cells that contain the endosymbiotic bacteria Buchnera aphidicola, are studied and it is experimentally demonstrated that bacteriocyte induction and proliferation occur independently of B. aphidICola.
A phylogeny of aphid parasitoids (Hymenoptera: Braconidae: Aphidiinae) inferred from mitochondrial NADH 1 dehydrogenase gene sequence.
TLDR
A phylogenetic study of Aphidiinae was undertaken, utilizing 465 bp of DNA sequence of the mitochondrial NADH1 dehydrogenase gene and suggested that in agreement with most of the previously proposed phylogenies, the aphidiines, each of the three recognized tribes (Praini, Ephedrini, Aphidiini), and most genera are monophyletic.
Phylogenetic relationships among genera of Aphidiinae (Hymenoptera: Braconidae) based on DNA sequence of the mitochondrial 16S rRNA gene
TLDR
Phylogenetic relationships among forty‐nine taxa representing twenty‐four genera of Aphidiinae (Hymenoptera: Braconidae) were investigated using DNA sequence of a portion of the mitochondrial 16S rRNA gene and parsimony analysis, suggesting that members of Aphidisinae are monophyletic.
Phylogenetic relationship among termite families based on DNA sequence of mitochondrial 16S ribosomal RNA gene
TLDR
Parsimony and distance analysis of DNA sequences supported the existing hypothesis that Mastotermitidae is the basal lineage among extant termites and the utility of 16S rRNA nucieotide sequence analysis for inferring phylogenetic relationships among termite families, subfamilies and genera is discussed.
Coevolution between a cockroach and its bacterial endosymbiont: a biogeographical perspective
TLDR
The analysis showed that the North American Cryptocercus are monophyletic, suggesting that a single colonization event was followed by vicariance, and there was complete concordance between the host and endosymbiont phylogenetic trees.
