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.

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.

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

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.

Allatostatin-like immunoreactivity in the abdomen of the locust Schistocerca gregaria
Cell and Tissue Research, 2006A polyclonal antibody against allatostatin 1 (AST-1) of cockroach Diploptera punctata was used to investigate the distribution of AST-like immunoreactivity within the abdomen of the locust, Schistocerca gregaria. In the abdominal ganglia, AST-like immunoreactivity was found in both cell bodies and neuropile.

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.

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 ...

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

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.

Neurobiology of polarization vision in the locustSchistocerca gregaria
Acta Biologica Hungarica, 2004The polarization pattern of the blue sky serves as an important reference for spatial orientation in insects. To understand the neural mechanisms involved in sky compass orientation we have analyzed the polarization vision system in the locust Schistocerca gregaria.
