Progress toward answering several remaining questions about Wolbachia evolution—such as which of their host effects are primitive and which are derived, the type of animals they first invaded, and how they were transferred between arthropods and nematodes—is currently hindered by a poor understanding of the relationships between the supergroups.

The first insect cellulase-endoding gene to be identified, RsEG, which encodes an endo-β-1,4-glucanase (EC 3.2.1.4) in the termite Reticulitermes speratus is described.

The inference of ancestral geographic ranges shows that the Termitidae, which includes more than 75% of extant termite species, most likely originated in Africa or Asia, and acquired their pantropical distribution after a series of dispersal and subsequent diversification events.

A test for correlated evolution which takes phylogenetic structure into account indicates that this pattern is of biological significance and suggests that the variable occurrence of a worker caste in termites has ecological determinants, apparently linked to differences in feeding and nesting habits.

A comparative study of cellulase expression in various termitid and flagellate‐harbouring species, using enzyme assays and reverse transcription polymerase chain reactions found taxa from phylogenetically basal lineages were consistently found to express endogenous genes specifically in the salivary glands, whilst those from a relatively apical lineage containing termitids expressed cellulases solely in the midgut.

TLC analysis showed that the cellulase produces cellotriose and cellobiose from insoluble cello-oligosaccharides, which is the first report of a family 5 cellulase from arthropods.

Midichloria mitochondrii is widespread in hard ticks (Ixodidae) and resides in the mitochondria of phylogenetically diverse species

A PCR screening for Midichloria-related bacteria in samples of ixodid ticks collected in Italy, North America and Iceland revealed that the bacteria form a monophyletic group within the order Rickettsiales, which indicates that bacteria invade mitochondria in at least 2 tick species.
