[Risk predictive model for damage caused by the spittlebug Aeneolamiapostica (Walker) Fennah (Hemiptera: Cercopidae)].

This paper evaluated the risk that Aenolamia postica (Walker) Fennah populations reach the economic threshold in sugar cane fields in Veracruz, México. A risk deductive model was constructed to include the sequence of events leading to damaging populations, considered the top event or critical failure in the crop. Model events were identified and quantified, and model was validated on field conditions.
