Morphology of the tibial organs of acrididae: Comparison of subgenual and distal organs in fore‐, mid‐, and hindlegs of Schistocerca gregaria (Acrididae, Catantopinae) and Locusta migratoria (Acrididae, Oedipodinae)

Journal of Morphology, 1995
AbstractThe structure of the complex tibial organs in the fore‐, mid‐, and hindlegs of two grasshopper species, Schistocerca gregaria (Acrididae, Catantopinae) and Locusta migratoria (Acrididae, Oedipodinae), is described. In each leg the tibial organs consist of two scolopale organs: the subgenual organ and the distal organ. Both organs are located in

Density dependence in rangeland grasshoppers (Orthoptera: Acrididae)

Oecologia, 1993
We tested for the existence of density dependence in annual adult rangeland grasshopper (Orthoptera: Acrididae) data from Montana, USA (1951-1991). Statistical density dependence was, in the sense of a stochastic equilibrium or return tendency, detected in all of the grasshopper mean density time-series from the three major physiographic regions of the

Chemosensory proteins of Locusta migratoria (Orthoptera: Acrididae)

Insect Biochemistry and Molecular Biology, 2000
We describe a family of proteins abundantly expressed in the chemoreception sensory organs, the antennae and legs, of the desert locust, Locusta migratoria (Orthoptera, Acrididae). Using polymerase chain reaction-based approaches and homology screenings, "OS-D"-like proteins were identified in L. migratoria. The different sub-types (LmigOS-Ds) are very

The femoral chordotonal organs of a grasshopper, orthoptera, acrididae

Journal of Neurocytology, 1975
The fine structure of the prothoracic and mesothoracic femoral chordotonal organs of a grasshopper, Romalea microptera, is described. A single chordotonal organ may contain more than 300 sensory units. Each unit includes the cell bodies and dendrites of two neurons, together with sheath cells of several kinds.

On acrididae (Orthoptera: acridoidea) from Kerala

Indian Journal of Entomology, 2018
A faunistic survey conducted on the acridid fauna of Kerala, India revealed 41 species belonging to 30 genera in 10 subfamilies of the family Acrididae. These led to five new records from Kerala. The subfamilies Oedipodinae and Catantopinae were observed to include maximum abundance.

Karyotype stability and DNA variability in the Acrididae

Chromosoma, 1966
The Acrididae are frequently quoted as one of the classic examples of karyotypic stability. Within the family, the Cryptosacci, for instance, are characterised by a majority of species having 23 chromosome arms in the male. The members are then related by Robertsonian sequences in which the basic karyotype is believed to consist of 23 acrocentric ...

Haemagglutinin activity in Acrididae (grasshopper) haemolymph

Journal of Insect Physiology, 1982
Abstract The haemolymph of Acrididae causes haemagglutination of human and animal erythrocytes. Thirteen of seventeen species tested had detectable activity and gave agglutination titres in the range 2–64, Melanoplus bivittatus, and M. sanguinipes showed greatest activity.

Revision of the Genus Aeoloplides (Orthoptera, Acrididae)

Annals of the Entomological Society of America, 1955
The major part of this study was carried out at the University of Kansas in 1946–48 under the direction of Dr. R. H. Beamer, as a thesis problem for the Master of Arts degree. At the University of Michigan in 1953–54, with the assistance of Dr. T. H. Hubbell, some uncertain points were cleared up and the manuscript was brought up to date and prepared ...
