Performance of Bollgard Ii in Arkansas in 2003
نویسندگان
چکیده
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 conventional cotton with respect to soybean looper defoliation. Bollgard and Bollgard II significantly out-yielded conventional cotton. Further evaluations of Bollgard II will be necessary to determine feasibility for Arkansas cotton production.

Bollgard 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 ...

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 کاملImpact of Bollworms [Helicoverpa zea (Boddie)] on Maturity and Yield of Bollgard Cotton
A large percentage of Bollgard cotton is treated for bollworms [Helicoverpa zea (Boddie)] with little information about economic losses from these infestations. The impact of bollworm infestations on maturity and yield of Bollgard cotton was determined. Infestations of 1-d-old bollworm larvae were established on non-Bollgard and Bollgard cottons in large field cages. Treatments included three a...

Two populations of Trichoplusia ni that had developed resistance to Bacillus thuringiensis sprays (Bt sprays) in commercial greenhouse vegetable production were tested for resistance to Bt cotton (BollGard II) plants expressing pyramided Cry1Ac and Cry2Ab. The T. ni colonies resistant to Bacillus thuringiensis serovar kurstaki formulations were not only resistant to the Bt toxin Cry1Ac, as prev...

Twenty crossbred lactating multiparous cows were used in a 28-day study to compare dry matter intake (DMI), milk yield, milk composition and Bacillus thuringiensis (Bt) protein concentrations in plasma when fed diets containing Bollgard II(®) cottonseed (BGII) or a control non-genetically modified isogenic cottonseed (CON). Bollgard II cottonseed contains the Cry1Ac and Cry2Ab insecticidal prot...
