Observations on the biology of Schistocerca venusta
<p>Statement Qf the problem. The green valley grasshopper, <em>Schistoceroa venusta Scudder,</em> is one of the most common grasshoppers to be found in the San Joaquin Valley and environs. Despite the fact that the insect is commonplace, very little work has been done on its biology. It was the …

Ion transport in the ileum of the desert locust Schistocerca gregaria, forskal
Recently, Audsley (1991) purified a neuropeptide factor - scgITP from the copora cardiaca of Shistocerca gregaria. ScgITP stimulates ileal reabsorption of Cl⁻, K⁺, Na⁺ and fluid and inhibits acid secretion. Stimulation with scgITP causes an increase in both Cl⁻ dependent short-circuit current and …

Environmental-Stress Tolerant Formulations of Metarhizium anisopliae var. acridum for Control of African Desert Locust (Schistocerca gregaria)
… the effects of spore coating infectivity to Schistocerca americana. Aerial conidia, submerged conidia, and blastospores produced in a high-osmolality liquid medium all had high desiccation tolerance relative to blastospores produced in Adamek's media. Blastospores produced in high osmolality …

A Time-Course Analysis of Behavioral Plasticity and Differential Gene Expression Patterns in Response to Density in Schistocerca americana (Orthoptera: Acrididae)
… large groups. The American Birdwing grasshopper, Schistocerca americana, is a non-swarming species related to the desert locust, S. gregaria, which shows density-dependent phenotypic plasticity in behavior, color, and morphology. In this thesis, I have identified the duration of crowding necessary …

Ventilatorische Rhythmogenese im isolierten Insektennervensystem
… Heuschreckenarten (Locusta migratoria, Schistocerca gregaria, Schistocerca americana, Taeniopoda eques) untersucht. Färbungen mit CoCl2 zeigten die Anatomie potentiell ventilatorischer Interneurone im Metathorakalganglion. Ein möglicherweise ventilatorisches intersegmentales Interneuron …

A pharmacological study of signal transduction mechanisms controlling fluid reabsorption and Ion transport in the locust rectum
… transport in the rectum of the desert locust, Schistocerca gregaria. Various agents known to block or activate specific signal transduction pathways were added to everted rectal sacs and short-circuited rectal flat-sheet bioassays. Cyclic AMP and its analogs were shown to stimulate rectal Jv …

Functional analysis of embryonic brain development in Tribolium castaneum
… hervorgehen. Jene Zellen konnten embryonal in Schistocerca und pupal in Drosophila identifiziert und lokalisiert werden, jedoch ist wenig bekannt über die Genetik, die die Identität der Neuroblasten determiniert und dadurch die Bildung des Zentralkomplexes ermöglicht. Das Faktum, dass larvale …

Purification, detection and biological effects of cyanobacterial toxins.
… toxins was developed using the desert locust Schistocerca gregaria. The locust bioassay was used in conjunction with an established high-performance liquid chromatography (HPLC) protocol to devise an extraction procedure for saxitoxins from cyanobacterial cells. It was also suitable for …

Functional design and scaling of the jumping mechanism of the African desert locust
… exoskeletal animal, the African Desert Locust (Schistocerca gregaria). It was found that the tibial leg segments of both the mesothoracic (ie. non-jumping) and the metathoracic (jumping) legs scaled in a manner that produced relatively longer, more slender skeletal elements as the animal grew. …
