Timely Application of Four Insecticides to Control Corn Earworm and Fall Armyworm Larvae in Sweet Corn [PDF]

Insects, 2022
Insecticide sprays are a common practice to control corn earworm, Helicoverpa zea (Boddie), and fall armyworm, Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), in corn (Zea mays L.) at reproductive stages. Our objectives were to determine (1)

Bt Trait Efficacy Against Corn Earworm, Helicoverpa zea, (Lepidoptera: Noctuidae) for Preserving Grain Yield and Reducing Mycotoxin Contamination of Field Corn [PDF]

Insects
The corn earworm, Helicoverpa zea (Boddie), causes persistent ear damage to corn grown in the southeastern United States region. Increased levels of ear damage have been associated with mycotoxin contamination in addition to yield loss.

Climate change, transgenic corn adoption and field-evolved resistance in corn earworm [PDF]

Royal Society Open Science, 2017
Increased temperature anomaly during the twenty-first century coincides with the proliferation of transgenic crops containing the bacterium Bacillus thuringiensis (Berliner) (Bt) to express insecticidal Cry proteins.

Overexpression of soybean trypsin inhibitor genes decreases defoliation by corn earworm (Helicoverpa zea) in soybean (Glycine max) and Arabidopsis thaliana [PDF]

Frontiers in Plant Science, 2023
Trypsin inhibitors (TIs) are widely distributed in plants and are known to play a protective role against herbivores. TIs reduce the biological activity of trypsin, an enzyme involved in the breakdown of many different proteins, by inhibiting the ...

Bycatch of common pollinators in pheromone baited traps for monitoring corn earworm (Lepidoptera: Noctuidae) in Missouri Industrial Hemp [PDF]

Journal of Cannabis Research
Background Several traps are recommended for monitoring corn earworm, Helicoverpa zea (Boddie), an important pest of field, vegetable and fruit crops in the U.S. These traps, which are meant to capture H. zea in many cases end up capturing other insects.

Genome-Wide Association and Metabolic Pathway Analysis of Corn Earworm Resistance in Maize [PDF]

The Plant Genome, 2018
Maize ( L.) is a staple crop of economic, industrial, and food security importance. Damage to the growing ears by corn earworm [ (Boddie)] is a major economic burden and increases secondary fungal infections and mycotoxin levels.

Fitness costs associated with Vip3Aa resistance on various hosts in Helicoverpa zea. [PDF]

Pest Manag Sci
Significant fitness costs associated with Vip3Aa resistance in H. zea were observed across three non‐Bt hosts. Abundant non‐Bt refuges could help limit the spread of Vip3Aa resistance in H. zea in the field. Abstract BACKGROUND Transgenic crops containing Bacillus thuringiensis (Bt) proteins are crucial for managing major agricultural pests such as the

Treatment of cotton with plant growth-promoting rhizobacteria consortium alters host location and oviposition of Spodoptera exigua. [PDF]

Pest Manag Sci
Two plant‐growth promoting rhizobacteria (PGPR) consortia (AU8 and TX1) induced a deterrence of host plant location and oviposition behavior of Spodoptera exigua females in both susceptible and resistant cotton plants. Most of the volatile organic compounds (VOCs) increased in PGPR‐treated plants compared to untreated plants. # indicates treatments not
