Gonad-specific virus of corn earworm

Differentiating tobacco budworm and corn earworm using near-infrared spectroscopy.

Near-infrared spectroscopy (NIRS) was used to develop a simple and quick technique to differentiate two economically important species, the tobacco budworm, Heliothis cirescens (F.), and corn earworm, Helicoverpa zea (Boddie), which are major pests of cotton, Gossypium hirsutum L., in the southern United States. In practice, it is difficult to distinguish the two species during their immature s...

Correction: Field-Evolved Resistance in Corn Earworm to Cry Proteins Expressed by Transgenic Sweet Corn

[This corrects the article DOI: 10.1371/journal.pone.0169115.].

Multi-state trials of Bt sweet corn varieties for control of the corn earworm (Lepidoptera: Noctuidae).

Field tests in 2010-2011 were performed in New York, Minnesota, Maryland, Ohio, and Georgia to compare Bt sweet corn lines expressing Cry1A.105 + Cry2Ab2 and Cry1Ab with their non-Bt isolines, with and without the use of foliar insecticides. The primary insect pest in all locations during the trial years was Heliocoverpa zea (Boddie), which is becoming the most serious insect pest of sweet corn...

A gene controlling biosynthesis of isoorientin, a compound in corn silks antibiotic to the corn earworm

The corn earworm (Helicoverpa zea Boddie) is an important pest of corn (Zea mays L.), and its larvae sometimes cause severe ear damage to hybrids grown in the southeastern United States. The antibiotic compound isoorientin is present in silks of some corn inbreds at a concentration that is harmful to corn earworm larvae. The inbred T218, which produces biologically active levels of this compoun...
