Helicoverpa armigera (H�bner)

The Old world bollworm feeds on a number of host plants, many of which commonly occur or are produced in the U.S. These plants include over 180 cultivated and wild species in at least 45 families. Old world bollworm larvae feed on several crops important to Indiana agriculture such as corn, soybeans, alfalfa, and tomatoes. About 5.9 million acres of corn, 5.8 million acres of soybeans, 625 thousand acres of alfalfa, and 7,000 thousands of acres of tomatoes are grown in Indiana each season.


Commodities Affected:
Field Crops, Forestry and Natural Areas, Fruits and Vegetables, Nursery, Ornamentals, and Turf


Knowledge of the existence of this pest species would be crucial to Indiana agriculture as the state grows nearly 12 million acres of corn and soybeans (two hosts of H. armigera); these two principal field crop commodities, corn ($1.7 billion) and soybeans ($1.3 billion), in Indiana have on the average a farm gate value slightly over $3 billion dollars. The production of alfalfa in Indiana averages an annual farm gate value of $140 million dollars. The production of tomatoes in Indiana averages an annual farm gate value of $35 million dollars.



The Old world bollworm is not known to occur in Indiana.
