Helicoverpa Zea Pest Control in Bt Sweet Corn Across Five U.S. States, 2024-2025

1.3 MB of field trial data from a 2024-2025 study testing Cry1A.105+Cry2Ab2 Bt sweet corn and chlorantraniliprole insecticide for Helicoverpa zea suppression. The dataset includes adult male moth trap capture counts and detailed ear damage assessments from plots in New York, Maryland, Delaware, Virginia, and North Carolina. Anders Huseth authored this dataset, which was last updated on 2026-05-28.

Use Cases

• Compare pest suppression efficacy of different silk-stage spray schedules based on the described 7, 4, or 2–3 day schedules.
• Analyze the relationship between adult moth trap captures and subsequent larval ear damage based on the separate 'TrapCaptures' and 'EarDamage' files.
• Evaluate the marginal benefit of combining Bt hybrids with insecticides based on the study's core hypothesis.
• Assess pest pressure variation between high and low pressure environments across the five U.S. states mentioned.

Strengths

• Data is explicitly from a multi-state study conducted in New York, Maryland, Delaware, Virginia, and North Carolina.
• Study was conducted over two years (2024 and 2025), providing temporal replication.
• Dataset includes two distinct, complementary data files: 'TrapCaptures' for moth counts and 'EarDamage' for kernel injury and larvae.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Data may reflect geographic bias inherent to the five selected U.S. states.
