Ultrastructure of the malpighian tubules of Schistocerca gregaria
Journal of Morphology, 1988AbstractThe ultrastructure of the Malpighian tubules of the adult desert locust, Schistocerca gregaria, is described. Male and female adults possess about 233 tubules, which empty proximally into the midgut‐ileal region of the alimentary canal by way of 12 ampullae. The tubules vary from 10 mm to 23 mm in length.

Immunocytochemistry of histamine in the brain of the locust Schistocerca gregaria
Cell and Tissue Research, 2004Histamine serves a neurotransmitter role in arthropod photoreceptor neurons, but is also present in a small number of interneurons throughout the nervous system. In search of a suitable model system for the analysis of histaminergic neurotransmission in insects, we mapped the distribution of histamine in the brain of the desert locust Schistocerca ...

Allatectomy and sexual receptivity in females of Schistocerca gregaria
Journal of Insect Physiology, 1977Abstract The removal of the corpora allata from immature females of Schistocerca gregaria causes the insects to enter a phase of permanent defence towards courting males. Operated control females copulate often, although they do not appear to show an active form of sexual display or attraction.

Peptides in the Locusts, Locusta migratoria and Schistocerca gregaria
Peptides, 1997The first peptide identified in locusts was adipokinetic hormone I (AKH-I), a neurohormone mobilizing lipids from the fat body. No other locusts peptides were isolated until 1985. From then on peptide identification started to boom at such a tremendously fast rate that even specialists in the field could hardly keep track.

Potential distribution of Schistocerca gregaria gregaria in southwestern Asia
Agricultural and Forest Entomology, 2021The northern subspecies of desert locust Schistocerca gregaria gregaria has recently expanded into western Asia. It poses a serious threat to food security in areas that are already socially and politically

A Nemestrinid Parasite of Schistocerca gregaria (Forsk.)
Nature, 1948DURING dissections of an immature male specimen of the desert locust, Schistocerca gregaria (Forskal), a yellowish larva of Nemestrinidae was found feeding on the testes and the surrounding adipose tissue. It was 1 cm. long. Its posterior end was surrounded by a chitinous cup leading to a slender respiratory tube c. 2 cm.

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

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 Anatomy of the Tarsi of Schistocerca gregaria Forsk�l
Zeitschrift f�r Zellforschung und Mikroskopische Anatomie, 1970The tarsus of S. gregaria is divided into three units (here called segments) and an arolium set between a pair of claws. The first segment bears three pairs of pulvilli in the fore and middle legs, and one pair and two single pulvilli in the hind legs. Segment two bears a pair of pulvilli, segment three one long pulvillus and the arolium a similar pad ...

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.
