Estimating species phylogeny from gene-tree probabilities despite incomplete lineage sorting: an example from Melanoplus
Recently, it has been hypothesized that the grasshopper Melanoplus
sanguinipes (Stal) may become infected with the virus by ingesting grass contaminated by the fluids of infected cattle.
They compared egg mortality rates of two common pest species of North American grasshoppers--Ageneotettix deorum, which lays shallow egg pods, and Melanoplus
sanguinipes, which lays deeper, more vertically oriented egg pods.
Relative importance of nymphal and adult resource availability for reproductive allocation in Melanoplus
sanguinipes (Orthoptera: Acrididae).

differentialis 2 3.
This was particularly acute in Nebraska in the 1800s when the migratory grasshopper, Melanoplus
A second proposal is Locustacarus trachealis became extinct in North America with the extinction of the grasshopper Melanoplus
spretus (Lockwood 2001).
Host specificity and molecular characterization of the entomopoxvirus of the lesser migratory grasshopper, Melanoplus
A team at Yale spooked Melanoplus
femurrubrum grasshoppers by raising them in cages with Pisaurina mira spiders with mouthparts glued shut so the arachnids could scare but not kill the insects.
One of these, the Melanoplus
entomopox-virus, looks promising.
2001), and a similar degree of blocking was observed on chloride currents induced by glutamate and ibotenate in the dorsal unpaired median (DUM) neurons of the cockroach, Periplaneta americana, and the grasshopper, Melanoplus
By studying one such trait--the ability to resist desiccation (drying) -- the researchers have determined that populations of the lesser migratory grasshopper, Melanoplus
sanguinipes, in different parts of Claifornia evolved varying abilities to withstand their local climates.
