Locusts
Although locusts are so destructive to the results of human agricultural industry, and although their presence must be regarded, at least in all cultivated countries, as a calamity of grave and serious import, their presence is, nevertheless, the opportunity of jubilee to various species of the lower creation. First, appears the inevitable crow, with his hop, jump, and caw, surfeiting himself o...

cells. Regardless, increasing evidence supports the idea that invadopodia are the subcellular structures required for ECM remodeling activity. Molecules such as the transmembrane metalloproteinase MT1-MMP are essential for invadopodia activity in vitro and have been shown by Steve Weiss’ laboratory and others to be important for tumor growth and invasion in vivo, suggesting that invadopodia are...
متن کاملCoordinated righting behaviour in locusts.
A locust placed upside down on a flat surface uses a predictable sequence of leg movements to right itself. To analyse this behaviour, we made use of a naturally occurring state of quiescence (thanatosis) to position locusts in a standardised upside-down position from which they spontaneously right themselves. Locusts grasped around the pronotum enter a state of thanatosis during which the limb...

migratoria migratorioide8 R. & F.) and in the eyes of Dro8ophila melanoga8ter (wild) andEphe8tia kilhniella have been investigated. 2. The pigments cannot be distinguished from each other. As the redox pigments reported in other insects also appear indistinguishable from our pigment, it is proposed that this widespread insect pigment be termed insectorubin. 3. Insectorubin has been isolated as ...
متن کاملHow locusts breathe.
Insect tracheal-respiratory systems achieve high fluxes and great dynamic range with low energy requirements and could be important models for bioengineers interested in developing microfluidic systems. Recent advances suggest that insect cardiorespiratory systems have functional valves that permit compartmentalization with segment-specific pressures and flows and that system anatomy allows reg...
