Temporal Expression Profiles and Bioactivity of Single (bollgard) and Dual-toxin (bollgard Ii) Bt Cotton
Laboratory studies were conducted using ELISA and bioassays (Helicoverpa zea) to investigate temporal Cry protein expression in field-grown single (‘Bollgard’) and dual-toxin (‘Bollgard II’) Bt cotton. In single-toxin Bt cotton, Cry1Ac levels changed significantly as the season progressed, exhibiting ca. 3-fold difference in Cry1Ac expression between the highest date (6.2 ppm—12 June) and the l...
متن کاملBollworm (Lepidoptera: Noctuidae) survival on 'Bollgard' and 'Bollgard II' cotton flower bud and flower components.
Genetically modified cotton, Gossypium hirsutum L., cultivars ('Bollgard') that produce crystalline proteins from Bacillus thuringiensis (Berliner) are valuable tools for managing lepidopteran insect pests in the United States. However, high numbers of bollworm, Helicoverpa zea (Boddie), larvae have been observed feeding in white flowers of these cultivars. Fresh tissue bioassays were conducted...
متن کاملBollgard II Efficacy on the Heliothine Complex
Bollgard cotton (Gossypium hirsutum L.) containing the CryIAc endotoxin of Bacillus thuringiensis Berliner became commercially available to cotton producers in 1996. Bollgard cultivars since that time have provided excellent control of the tobacco budworm, Heliothis virescens F., for growers in Arkansas. Control of bollworm, Helicoverpa zea (Boddie), and other lepidopterous pests has been less ...
متن کاملPerformance of Bollgard Ii in Arkansas in 2003
Bollgard® II was compared to Bollgard® and conventional (i.e., non-Bt) cotton in order to observe effectiveness against the Heliothine complex and various lepidopterous pests. In the trial, Bollgard II and Bollgard performed marginally better when compared to conventional cotton with respect to square, bloom, and boll damage. Bollgard II performed significantly better than Bollgard and conventi...
