..., but it is unknown whether the leak of the gut microbiome is a possible immune trigger in the cold. We developed a novel feeding protocol to load the gut of locusts ( Locusta migratoria ) with fluorescent bacteria before exposing them to −2°C for up to 48 h. No bacteria were recovered from the hemolymph of cold...

... investigated the hypothesis to ‘programme’ jumping escape direction as well as surveillance orientation in young and adult individuals of Locusta migratoria as an adaptive consequence of prior exposure to directional-biased predator approaches generated by a robotic leopard gecko representing Eublepharis...

Cold stress caused gradual muscle cell death, which coincided with a loss...

.... This is corroborated in the economically important locust species Locusta migratoria and Schistocerca gregaria . Here, we review the key elements involved in phase transition in locusts and possible epigenetic regulation. We discuss the relative role of DNA methylation, histone modification and small RNA molecules...

...Lisa Robertson; Andrew Donini; Angela B. Lange The scanning ion-selective electrode technique (SIET) was utilized for the first time in Locusta migratoria to characterize K + transport along the digestive tract and to determine the effect of two locust FGLamide allatostatins (FGLa/ASTs) on K...

The present study focuses on the dynamics of a new and simple model of intestinal epithelial regeneration found in the midgut of the migratory locust, Locusta migratoria (Linnaeus 1758). The locust midgut consists of three cell types: columnar cells, endocrine cells...
