Spatial and temporal variability in host use by Helicoverpa zea as measured by analyses of stable carbon isotope ratios and gossypol residues
JOURNAL OF APPLIED ECOLOGY, 47(3), 583–592.
author keywords: Bacillus thuringiensis; cotton; cotton bollworm; insect resistance management; refuge
TL;DR:
Structured refuges, consisting of non-Bt cotton, have been a mandated part of this strategy to produce non-selected insects that are temporally and spatially synchronous with insects from the Bt crop, diluting Bt resistance alleles through mating.

Cross-resistance responses of Cry1Ac-selected Heliothis virescens (Lepidoptera : Noctuidae) to the Bacillus thuringiensis protein Vip3A
JOURNAL OF ECONOMIC ENTOMOLOGY, 100(1), 180–186.
author keywords: Bacillus thuringiensis; Vip3A; Heliothis virescens; cross-resistance; resistance management
TL;DR:
Results of these experiments demonstrate that cross-resistance is nonexistent between Cry1Ac and Vip3A in H. virescens, and the introduction of VIP3A-producing lines could delayCry1Ac-res resistance evolution in H., if these lines gain a significant share of the market.

Effect of tobacco budworm (Lepidoptera : Noctuidae) infestation level on budworm-resistant and susceptible varieties of flue-cured tobacco in north Carolina
JOURNAL OF ECONOMIC ENTOMOLOGY, 100(3), 801–807.
author keywords: flue-cured tobacco; treatment threshold; damage relationships; infestation
TL;DR:
The results provide economic support for tolerance of a higher treatment threshold for resistant varieties, as the combination of pest pressure and the benefit of host plant resistance must be greater than the capacity of a susceptible variety to produce competitive yields, despite sustaining significantly higher loss.

Limitations of stable carbon isotope analysis for determining natal host origins of tobacco budworm, Heliothis virescens
ENTOMOLOGIA EXPERIMENTALIS ET APPLICATA, 126(1), 46–52.
author keywords: Lepidoptera; Noctuidae; host plant utilization; isotope ratio mass spectrometry; biological markers
TL;DR:
Results demonstrate that within the range of C3 host plants tested, carbon isotope signatures are not sufficiently unique to enable a reliable determination of natal origin of feral tobacco budworm with current IRMS technology.

TL;DR:
The addition of pyrethroid oversprays to Bollgard II cotton seemed to be the best resistance management strategy available for bollworm because no bollworms were capable of completing development under these conditions.

Performance of feral and Cry1Ac-selected Helicoverpa zea (Lepidoptera : Noctuidae) strains on transgenic cottons expressing one or two Bacillus thuringiensis ssp kurstaki proteins under greenhouse conditions
JOURNAL OF ENTOMOLOGICAL SCIENCE, 39(1), 46–55.
author keywords: Bacillus thuringiensis; Helicoverpa zea; bollworm; cotton
TL;DR:
Transgenic cottons that express either one or two Bacillus thuringiensis Berliner proteins, respectively, along with the conventional sister genotype, demonstrated that when averaged across bollworm strains, the Bollgard II genotype significantly reduced larval survival and fruit penetration by bollworms compared to the Boll Gardner variety.

TL;DR:
The bollworm outbreak on Bt cotton is not a manifestation of physiological resistance predicted in 1991, but rather, the epidemic apparently arises from extant populations that have the inherent ability to discriminate among tissues with varying concentrations of the toxin within a plant.
