migratory grasshopper การใช้

Migratory grasshopper, " Melanoplus sanguinipes : " destructive to grass as well as crops . 7 / 8 to 1 1 / 8 inches long; they are strong fliers and can swim long distances.
Another article ( Jeschke and Tollrian, 2005, Ethology 111, pp187 206 ) listed migratory grasshopper ( Melanoplus sanguinipes ) digestion time as 42044 minutes per gram of dry mass, carolina grasshopper ( Dissosteira carolina ) as 12818 min / g ( dry ) and undulate winged grasshopper ( Circotettix undulatus ) as 16011 min / g ( dry ).
Because locusts are a form of grasshopper that appear when grasshopper populations reach high densities, it was theorized that " M . spretus " might not be extinct, that " solitary phase " individuals of a migratory grasshopper might be able to turn into the Rocky Mountain locust given the right conditions; however, breeding experiments using many grasshopper species in high-density environments failed to invoke the famous insect.
