Grasshopper Conditions in Colorado

Hydrologic Conditions Describe West Nile Virus Risk in Colorado

We examine the relationship between hydrologic variability and the incidence of human disease associated with West Nile virus (WNV; family Flaviviridae, genus Flavivirus) infection (hereafter termed "human WN cases") in Colorado from 2002 to 2007. We find that local hydrologic conditions, as simulated by the Mosaic hydrology model, are associated with differences in human WN cases. In Colorado'...

Grasshopper Management.pmd

Grasshoppers are divided into two major subgroups: the short-horned grasshoppers (Figure 1) and the long-horned grasshoppers, Mormon crickets and katydids (Figure 2). Short-horned grasshoppers are responsible for most of the reported crop losses. As a result, individuals of this subgroup are popularly referred to as “grasshoppers.” Figure 1. A mature two-striped female grasshopper (Melanoplus b...

Oviposition Digging in the Grasshopper

1. Transection of the ventral nerve cord of female grasshoppers activates the rhythmical motor programme for oviposition digging. 2. Electrical stimulation of the cut nerve cord had the following effects on elicited oviposition motor activity: (i) shortand long-lasting inhibition of activity, (ii) phase resetting and (iii) modulation of burst frequency. 3. Cold saline applied to the nerve cord ...

Persistence in the Grasshopper Kernel †

The Grasshopper operating system provides explicit support for orthogonal persistence. A consequence of this is that the kernel itself must, in part, be persistent. To conform to the model of persistence in Grasshopper, the kernel persistent store must provide a means to stabilise entities independently of each other and must also be able to maintain an arbitrary number of versions for each ent...
