1. Astaxanthin (3:3 - dihydroxy - 4:4 -diketo - B -carotene) and B-carotene both occur as chromoproteins in the integument of locusts and the green chromoprotein pigment of many insects (known as insectoverdin) is a complex, the yellow-orange component of which may have as its prosthetic group B-carotene (Carausius), lutein (Sphinx, Tettigonia) or astaxanthin.
2. Though the epicuticular lipids play a major role in reducing water loss through the integument, it now seems unlikely that this depends on an oriented layer of wax molecules subject to disruption at a critical transition temperature (Hackman, 1971).
3. It may denote (i) the external groove or sulcus corresponding to an internal ridge-like inflection of the cuticle which provides mechanical rigidity, or (ii) a line of thinner, weaker cuticle along which rupture or bending of the integument can occur at ecdysis, or (iii) a narrow, flexible, membranous zone of unsclerotized cuticle, or (iv) a linear impression without any obvious mechanical significance.
4. Reviews of various general aspects of the insect integument have been given by Beament (1961, 1964), Hackman (1971, 1974), Hinton (1970), Lawrence (1967), Locke (1964, 1967), Neville (1967, 1970, 1975), Weis-Fogh (1970) and Wigglesworth (1959).
5. The integument also includes enzyme systems responsible for the synthesis and degradation of the major cuticular materials and those involved in melanization and sclerotization; many of these systems require fuller investigation.
6. Blood-filled spaces or lacunae soon develop in the wing-pad (appearing in the and instar of Pteronarcys, for example) and alter as growth proceeds so that in the later instars the lacunae correspond in arrangement to the veins of the adult wings; the veins, in fact, arise by differential sclerotization of the integument adjacent to the lacunae.
7. Groups of sensilla at the base of the halteres are stimulated by deformations of the integument when the halteres vibrate and the resulting pattern of nervous impulses is modified by the addition of torques due to the turning movements of the fly.
8. THE INTEGUMENT
9. The procuticle, which may be absent from the tracheoles, is secreted by the epidermal cells and makes up the bulk of the integument.
10. The integument consists of the following layers: (i) the cuticle, (ii) the epidermis, and (iii) the basement membrance (Fig. 2).
11. The state served the processes of capitalist reproduction, exerted influence on it, as the corresponding political integument - and only thus , whilst the economic regularities took shape on the basis of the spontaneity of the entire process as a whole.
12. The Structure and Development of Wings - Wings are thin plate-like expansions of the integument which are strengthened by a framework of hollow sclerotized tubes known as veins.
13. Xanthopterin and leucopterin are also found in the integument of the Vespidae, while the body- and wing.scales of many Pierid butterflies contain leucopterin, xanthopterin, isoxanthopterin and erythropterin.
