Summary.Termite workers from all families examined had no arolia (=adhesive pads) on their tarsi and are unable to climb smooth vertical surfaces such as glass or polypropylene plastic. This contrasts with ants where both workers and alates of most species possess arolia and are able to climb these surfaces. Arolia were present in alates of the majority of species investigated from three of the four most basal termite families (Mastotermitidae, Termopsidae and Kalotermitidae), though absent… 

An Introduction to Termites: Biology, Taxonomy and Functional Morphology

It is now clearly established that termites are a very specialised form of cockroach, with far more complex social systems than other cockroaches, and with a far wider range of diets.

A Dark-Necked Drywood Termite (Isoptera: Kalotermitidae) in Italy: Description of Kalotermes italicus sp. nov.

The yellow-necked drywood termite, Kalotermes flavicollis (F), so called due to the yellow pronotum of its alates, is the only species in the genusKalotermes known for Europe and differs morphologically from the other Kaloterme species known for the circum-Mediterranean lands.

The phylogenetic system of Mantodea (Insecta: Dictyoptera)

It is shown that many morphological characters, e.g. the head processes, enlarged lateral lobes of the pronotum, lobes on the legs and on the abdomen, evolved convergently several times during the evolution of the praying mantises (Mantodea).

Two functional types of attachment pads on a single foot in the Namibia bush cricket Acanthoproctus diadematus (Orthoptera: Tettigoniidae)

Insects have developed different structures to adhere to surfaces. Most common are smooth and hairy attachment pads, while nubby pads have also been described for representatives of Mantophasmatodea,

Progress in Organic Coatings

Many insects are considered to be pests and can be serious threats to buildings. Insecticides represent an effective way to control pest insects but are harmful to the environment. As an

Molecular Basis Underlying Caste Differentiation in Termites

This chapter provides examples of approaches to study the molecular bases of caste differentiation, and describes molecular biology approaches for gene and protein discovery and characterization, relevant genes and proteins that have been identified, and a contextual foundation on which genome sequencing can now be considered.

Alternative Tasks of the Insect Arolium with Special Reference to Hymenoptera

Apterigous terrestrial insects walk over relatively flat surfaces the radii of curvature of which are not less in size than their bodies or legs, and machilids run extremely fast on stones and rocks of an arbitrary inclination.



Taxonomy and Phylogeny of Termites

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.

Characterizing the Ancestors: Paedomorphosis and Termite Evolution

It is suggested that the tempo and mode of their evolution confound efforts to determine the phylogenetic relationships among termites, mantids, and cockroaches, and that recognition of the connection between ontogeny and phylogeny in the Dictyoptera is essential to resolving some of the long standing issues regarding the phylogenetics origin and subsequent evolution of the included taxa.

Slippery ant-plants and skilful climbers: selection and protection of specific ant partners by epicuticular wax blooms in Macaranga (Euphorbiaceae)

The genus Macaranga represents one of the few cases known so far where epicuticular wax crystals are likely to have evolved in relation to insects and act as an ecological isolation mechanism for the sympiotic ants.

Ultrastructure of attachment specializations of hexapods (Arthropoda): evolutionary patterns inferred from a revised ordinal phylogeny

The analysis demonstrates, that similar structures (arolium, euplantulae, hairy tarsomeres) have evolved independently in several lineages, and some of them support monophyletic groups (e.g. Embioptera + Dermaptera; Dictyoptera + Phasmatodea; Hymenoptera+ Mecopterida; Neuropterida + Strepsiptera + Coleoptera).

Phylogenetic status, distribution, and biogeography of Cryptocercus (Dictyoptera : Cryptocercidae)

The traditional classification and proposed geographic time frame for evolution of this taxon are retained, supported by recent estimations of molecular evolution on endosymbionts and by geological evidence indicating a window of opportunity for transcontinental movement in North America for an insect with the ecological requirements of Cryptocercus.

Cryptotermes chacoensis, a new species from native South American inland habitats (Isoptera : Kalotermitidae)

The imago and soldier castes of a new species, Cryptotermes chacoensis Roisin, are described from four series collected in the Gran Chaco. This species is remarkable for occurring in natural habitats

Functional morphology of the pretarsus in larval Thysanoptera

Legs of larval thrips differ in form and function from those of the adults. The tarsal depressor muscle and tibial gland of the adult are absent, the trochanter and tarsus are fused to the femur and


It is indicated that arolia are universally present in ants outside the subfamilies Ponerinae and Leptanillinae, and some ponerine groups possess arolIA, while others do not.

Reconstructing the past of Cryptocercus (Blattaria: Polyphagidae): Phylogenetic Histories and Stories

Facts indicate that Cryptocercus has a surprisingly high dispersal ability and that its present preferenda and distribution suggest a late Tertiary origin, and speculations about unwarrantedly clock-like evolution and dubious fossil records should not be preferred to both congruent phylogenetic framework and facts.
