grasshoppers (  ) on burley tobacco (Nicotiana tabacum (burley type)) - 1440125


Host: burley tobacco (Nicotiana tabacum (burley type) L.)
Descriptor: Damage
Description: Grasshoppers [various species including differential grasshopper, Melanoplus differntialis (Thomas) and redlegged grasshopper, Melanoplus femurrubrum (DeGeer)] chew irregular holes between veins of leaves. Adult redlegged grasshoppers are 3/4 to 1 inch long. They are greenish-gray to olive-green or reddish-brown with a yellowish underside. The hind tibiaae are red with black spines. The differential grasshopper is 1 1/2 to 2-inches long with a shiny, brownish-yellow color and black V-shaped marks on the outer face of the yellow femur. Immature (nymphs) are similar but lack fully developed wings. Most species prefer other plants but will eat tobacco if their food supply is inadequate. Grasshoppers often migrate into tobacco fields from ditch banks and grasslands, especially when populations are high during droughts and following hay mowing or other habitiat modifications. Tobacco injury usually starts along the edges of fields and is more common late in the growing season.
