4. Adaptabilidade de híbridos entre Gossypium barbadense E G. hirsutum N contendo o gene cry1Ac
Hybrids among transgenic plants and related species are expected to occur if they are sympatric and when there are not crossing barriers; as is the case, in Brazil, of cry1Ac transgenic cotton and Gossypium barbadense. This species has been maintained as dooryard plants, and should be preserved as a genetic resource. Hybrids were evaluated about traits relat

5. Estudos bio-ecologicos de Bracon vulgaris ashmead (Hymenoptera: braconidae), ectoparasito de anthonomus grandis Boheman, 1843 (Coleoptera: curculionidae)
The objetive of this work was to investigate ecological aspects and comparative biology of Brcron vulgaris Ashmead (Hymenoptera: Braconidae), an ectoparasite of both Anthonomus grandis BOHEMAN, 1843 (Coleoptera: Curculionidae), the boll wevil and Pectinophora gossypiella SAUNDERS, 1843 (Lepidoptera: Gelechiidae), the pink bollwonn, which are considered as ke

6. Field accumulation of aflatoxin in cottonseed as influenced by irrigation termination dates and pink bollworm infestation.
Aflatoxin accumulation in Deltapine 16 cottonseed, grown in Yuma, Ariz., in a 3-year study, was significantly influenced by the timing of irrigation terminations and by level of pink bollworm infestations. In 1971 and 1972, termination of irrigations by early August resulted in significantly less aflatoxin than in plots where two additional irrigations were

7. Frequency of resistance to Bacillus thuringiensis in field populations of pink bollworm
Strategies for delaying pest resistance to genetically modified crops that produce Bacillus thuringiensis (Bt) toxins are based primarily on theoretical models. One key assumption of such models is that genes conferring resistance are rare. Previous estimates for lepidopteran pests targeted by Bt crops seem to meet this assumption. We report here that t

8. Cyt1A from Bacillus thuringiensis Lacks Toxicity to Susceptible and Resistant Larvae of Diamondback Moth (Plutella xylostella) and Pink Bollworm (Pectinophora gossypiella)
We tested Cyt1Aa, a cytolytic endotoxin of Bacillus thuringiensis, against susceptible and Cry1A-resistant larvae of two lepidopteran pests, diamondback moth (Plutella xylostella) and pink bollworm (Pectinophora gossypiella). Unlike previous results obtained with mosquito and beetle larvae, Cyt1Aa alone or in combination with Cry toxins was not highly toxic

9. Control of Resistant Pink Bollworm (Pectinophora gossypiella) by Transgenic Cotton That Produces Bacillus thuringiensis Toxin Cry2Ab
Crops genetically engineered to produce Bacillus thuringiensis toxins for insect control can reduce use of conventional insecticides, but insect resistance could limit the success of this technology. The first generation of transgenic cotton with B. thuringiensis produces a single toxin, Cry1Ac, that is highly effective against susceptible larvae of pink bol

10. Cross-Resistance of Pink Bollworm (Pectinophora gossypiella) to Bacillus thuringiensis Toxins
Two strains of pink bollworm (Pectinophora gossypiella) selected in the laboratory for resistance to Bacillus thuringiensis toxin Cry1Ac had substantial cross-resistance to Cry1Aa and Cry1Ab but not to Cry1Bb, Cry1Ca, Cry1Da, Cry1Ea, Cry1Ja, Cry2Aa, Cry9Ca, H04, or H205. The narrow spectrum of resistance and the cross-resistance to activated toxin Cry1Ab sug

11. Long-term regional suppression of pink bollworm by Bacillus thuringiensis cotton
Despite the potentially profound impact of genetically modified crops on agriculture and the environment, we know little about their long-term effects. Transgenic crops that produce toxins from Bacillus thuringiensis (Bt) to control insects are grown widely, but rapid evolution of resistance by pests could nullify their benefits. Here, we present theoretical

12. Three cadherin alleles associated with resistance to Bacillus thuringiensis in pink bollworm
Evolution of resistance by pests is the main threat to long-term insect control by transgenic crops that produce Bacillus thuringiensis (Bt) toxins. Because inheritance of resistance to the Bt toxins in transgenic crops is typically recessive, DNA-based screening for resistance alleles in heterozygotes is potentially much more efficient than detection of res
