Using a simulation model as an analysis tool, the economic impact of spittlebugs in pastures of Colombia was quantified in terms of animal production. Three levels of abundance (10, 25, 50 adults/m2 ) and farm area affected (25, 50, 100%) were evaluated using data obtained in Brazil for Notozulia...
