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

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.

Development, survival, and feeding behavior of Helicoverpa zea (Lepidoptera: Noctuidae) relative to Bt protein concentrations in corn ear tissues.

PLoS ONE, 2019
The corn earworm, Helicoverpa zea (Boddie) (Lepidoptera: Noctuidae), preferentially oviposits and feeds on ears of corn (Zea mays L.) and can be managed using transgenic hybrids that produce insecticidal proteins from the bacterium Bacillus thuringiensis

Corn Earworm Picks up Activity in Iowa

, 2019
Corn earworm (Photo 1) is common in Iowa corn. It is a migratory pest, migrating from the southern and southeastern U.S. every summer. There are two general fights to the Midwest every summer, but the first flight is not of economic concern.

Corn Earworm Control: Formulations

The Florida Entomologist, 1952
for DDT dust and 1% for the untreated check. An exhaustive study followed this experiment in an attempt to eliminate pollination and yield damage without sacrificing the excellent control obtained. At the end of these trials, however, it wasconcluded that oil solutions of DDT were not safe enough for a general recommendation.
