Vulva has short lips and distinctive cuticular cone (Fig.
Based on the idea that cuticular waxes are critical for limiting water loss from fruit, and thus for resisting desiccation and spoilage, we propose to uncover the structural and regulatory pathways that mediate its biosynthesis, transport and assembly in response to drought stress through a multidisciplinary approach.
No cuticular layer was observed between the mesophyll and the basal cell (Levering & Thomson, 1971; Amarasinghe & Watson, 1988).
Such treatment reduces physical strength of especially fibrous feed, disrupts the silicified cuticular barrier and cleavages of some lignin-carbohydrate bonds (Schiere and Nell, 1993; Van Soest, 2006).
The carbohydrates, as energy elements play a crucial role in the physiology, while the lipids represent the independent source of energy in insects and are transported via the hemolymph from their site of storage towards the user organs, in particular the vitellogenesis and cuticular synthesis [6, 36].
These structures are cuticular extensions, with shafts of different shapes and sizes, that can function as mechanoreceptors and/or chemoreceptors.
The diagnosis in the described case is probably best left as a Dirofilaria species of the Dirofilaria (Nochtiella) type, members of which exhibit marked cuticular ridging, and not D.
Over 100 kinds of proteins are known to occur in insect cuticle, functions of which include pigmentation and cuticular hardness (Hopkins and Kramer 1992; Chapman 1998).
Delayed cuticular penetration and enhanced metabolism of deltamethrin in pyrethroid resistant strains of Helicoverpa armigera from China and Pakistan.
Analysis showed the substance was comprised of waxy fats called cuticular lipids secreted by insects to regulate water loss.
