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.

Courtship inhibition pheromone in desert locusts, Schistocerca gregaria
Journal of Insect Physiology, 2002Male desert locusts in the gregarious phase release phenylacetonitrile (PAN) on becoming sexually mature. It has been assumed that this chemical is responsible for aggregation of adult desert locusts. However, PAN has repellent characteristics and is involved in sexual behavior.

Anatomical organization of the cerebrum of the desert locust Schistocerca gregaria
Cell and Tissue Research, 2018The desert locust Schistocerca gregaria is a major agricultural pest in North Africa and the Middle East. As such, it has been intensely studied, in particular with respect to population dynamics, sensory processing, feeding behavior flight and locomotor control, migratory behavior, and its neuroendocrine system.

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 ...

Potassium channels of adult locust (Schistocerca gregaria) muscle
Pflügers Archiv - European Journal of Physiology, 1996Two types of K+ channels have been identified in patches of plasma membrane of metathoracic extensor tibiae muscle fibres of adult locust, Schistocerca gregaria. One channel had a maximum conductance of 170 pS, fast open-closed kinetics, and a linear current/ voltage relationship. In inside-out patches it was activated by "internally applied" Ca2+, but

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.

Componental analysis of the ocellar electroretinogram of the locust, Schistocerca gregaria
Journal of Insect Physiology, 1975Abstract Ruck 's componental analysis of the ocellar electroretinogram (ERG) has been reappraised using techniques of signal averaging and waveform subtraction. Components (1), (3), and (4) can readily be isolated in the locust ocellus but component (2) as recorded in the locust ocellus is probably an artefact.

Immunocytochemistry of dopamine in the brain of the locust Schistocerca gregaria
Journal of Comparative Neurology, 1992AbstractCatecholamine‐induced histofluorescence studies have suggested a rich innervation of the locust brain by dopamine‐containing neurons. To provide a basis for future studies on dopamine action in this insect, the location and morphology of neurons reacting with antisera against dopamine were investigated in the supraoesophageal ganglion of the ...

Membrane specialisations of the neuromuscular junction of the locust, Schistocerca gregaria
Cell and Tissue Research, 1983The ultrastructure of locust (Schistocerca gregaria) neuromuscular junctions as observed in freeze-fracture replicas is described and correlated with their appearance in thin sections of material prepared by various fixation regimes and by use of the sectioned replica technique. Two main specialisations are found at the junction. Postsynaptically there
