Helicoverpa armigera

Scientific name: Helicoverpa armigera

Crop: soybean

Damages: Caterpillars of Helicoverpa armigera can feed on both plant and reproductive organs, such as leaves, stems, flower buds and pods.

Behavior:

• Eggs are laid preferably on the abaxial face of the leaves or on the stems, flowers, fruits, and flower buds.
• Pupal development occurs in the soil and pupae can enter a diapause stage, depending to the climatic conditions.
• The color of the caterpillars is influenced by the instars and the food they ingest.

Control

End of caterpillar resistance!

Bacillus thuringiensis has different crystals in its composition: Cry1Aa, Cry1Ab, Cry1Ac, Cry2Aa, and Cry2Ab. This characteristic makes Bacillus thuringiensis an important tool for the management of the complex resistance system of caterpillars.
