Axonal degeneration within the tympanal nerve of Schistocerca gregaria
Cell and Tissue Research, 1999This study describes time course and ultrastructural changes during axonal degeneration of different neurones within the tympanal nerve of the locust Schistocerca gregaria. The tympanal nerve innervates the tergit and pleurit of the first abdominal segment and contains the axons of both sensory and motor neurones. The majority of axons (approx.

The embryonic apolyses of Schistocerca gregaria (Orthoptera)
Journal of Insect Physiology, 1972Abstract The origin and differentiation of the ecdysial glands and the appearance of the cuticles were studied in embryos of Schistocerca gregaria at corresponding stages. The development of the cuticle was also studied in headless embryos explanted in vitro. The ecdysial glands originate in the early stages before blastokinesis from two symmetrical

The energetics of the jump of the locust Schistocerca gregaria
Journal of Experimental Biology, 1975ABSTRACT The anatomy of the metathoracic leg is redescribed with particular reference to storage of energy in cuticular elements and the way in which the stored energy is used in jumping. The jump of adult male locusts requires an energy of 9 mJ and that of the female requires 11 mJ.

Standardized atlas of the brain of the desert locust, Schistocerca gregaria
Cell and Tissue Research, 2008In order to understand the connectivity of neuronal networks, their constituent neurons should ideally be studied in a common framework. Since morphological data from physiologically characterized and stained neurons usually arise from different individual brains, this can only be performed in a virtual standardized brain that compensates for ...

The fine structure of the ocelli of Schistocerca gregaria
Cell and Tissue Research, 1979A study of the organisation of the locust dorsal ocellus shows that the structure is designed to provide the maximum possible effective aperture. The condenser-like cuticular lens and the dispersal of the rhabdome over a large proportion of the circumferential area of the retinula cells increases the light gathering power of the eye.

The dynamics of yolk deposition in the desert locust Schistocerca gregaria
Journal of Insect Physiology, 2007Injection of the protein dye Fast Green or the fluid-phase probe fluorescein dextran into the haemolymph of vitellogenic female desert locusts (Schistocerca gregaria) resulted in their incorporation into oocytes. We used Fast Green to study the physical dynamics of yolk deposition during vitellogenesis.

THE LIFE-HISTORY OF SCHISTOCERCA LINEATA SCUD
The Canadian Entomologist, 1932The lined grasshopper, Schistocerca lineata Scud., is the only one of the genus met with in the Prairie Provinces, although it has as relations, several famous locusts of the Old World and South America including the desert locust, Schistocerca gregaria Forst., and S. paranensis Burm.

Cuticular sclerotization in larval and adult locusts, Schistocerca gregaria
Journal of Insect Physiology, 1974Abstract The sclerotization of both larval and adult cuticle from the desert locust, Schistocerca gregaria , has been studied by measuring the incorporation of radioactive dopamine and N-acetyldopamine into the cuticle. The results are compared with the degree of sclerotization of the cuticle and the amount of sclerotizing enzyme present.
