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

Chromosomal repatterning in Acrididae.

Cytobios, 1978
Studies on the chromosomes of the acridid grasshoppers Acrida turrita, Poekilocerus pictus and Chrotogonus oxypterus have led the authors to surmise that structural re-arrangements must have played a major role in chromosomal repatterning and karyotypic evolution.

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.

LOCUST (ACRIDIDAE) IN THE REPUBLIC OF BURYATIA

Вестник Бурятской государственной сельскохозяйственной академии имени В. Р. Филиппова, 2019
В Республике Бурятия из саранчовых распространены сибирская, белополосая, темнокрылая, ширококрылая и крестовая кобылки. В результате их деятельности ежегодно на огромной территории обесцениваются луга и пастбища, а в годы массовых размножений страдают посевы сельскохозяйственных культур.

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

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

Communicative Mandible-Snapping in Acrididae (Orthoptera)

Science, 1960
Paratylotropidia brunneri Scudder is the first insect known to possess a long-range mandibular sound signal. This signal probably evolved through a stage in which feeding noises were significant; it is believed to be a functional analog of other insect calling sounds.
