Proteasas digestivas de tipo tripsina del taladro del maíz, "Sesamia nonagrioides" (Lepidoptera, Noctuidae), caracterización e interacción con la proteína insecticida Cry1Ab
… expresa un fragmento de la proteína insecticida Cry1Ab de la bacteria Bacillus Thuringiensis (Bt), comercializado en España desde 1998, ofrece una alternativa al uso de insecticidas químicos para el control de esta plaga. El mayor problema que puede presentar la tecnología de plantas transgénicas …

Monitoring der Resistenzentwicklung des Maiszünsler (Ostrinia nubilalis), Hübner) gegenüber Bt-Mais
… Die Untersuchungen wurden mit gereinigtem Cry1Ab-Toxin, das in E. coli produziert wurde, durchgeführt. Sowohl das Cry1Ab-Protoxin als auch trypsinisierte Toxine wurden verwendet. Die Resistenzallelfrequenz kann durch mehrere Methoden ermittelt werden. In dieser Arbeit wurden das …

FATE, TRANSPORT, AND MIXTURE TOXICITY OF TRANSGENIC BACILLUS THURINGIENSIS CORN (ZEA MAYS) AND ASSOCIATED INSECTICIDES
… was to measure the environmental fate of the Cry1Ab Bt corn protein, clothianidin, and tefluthrin and determine if measured concentrations could be causing effects to non-target species. The Cry1Ab proteins persisted only during the corn growing season in soil, runoff water and sediment with …

Maíz Bt : seguimiento de la resistencia de Sesamia nonagrioides (Lepidoptera: Noctuidae) y Ostrinia nubilalis (Lepidoptera: Crambidae) y efectos en artrópodos depredadores
… (derivada del evento 176, que expresa la toxina Cry1Ab) en zonas representativas del cultivo del maíz en España. Para dichas poblaciones se calculó la concentración de Cry1Ab que mata al 50% de la población (CL50) y se comparó en el tiempo para determinar cambios en la susceptibilidad. No se …

PCR-based Synthesis of Codon Optimized cry2Aa Gene for Production of Shoot and Fruit Borer (Leucinodes orbonalis) Resistant Eggplant (Solanum melongena L.) Cultivars
… more toxic to brinjal shoot and fruit borer than Cry1Ab. My objective was to develop eggplant cultivars that express a codon-optimized cry2Aa gene, the sequence of which is based on that of an Indian isolate of Bt, with the eventual goal of producing fully resistant cultivars. The cry2Aa gene was …

Transgenic Insecticidal Corn and Coleomegilla Maculata
… mir 1, and transgenic hybrids that expressed Cry1Ab or Cry3Bb1) did not influence the fitness of C. maculata in the laboratory. This observation is in spite of the reduced quality of prey fed some of the insect-resistant hybrids. Finally, we observed that coccinellids respond to anthesis by …

Modeling insect resistance to transgenic corn and cowpea
… and a MDT. Major resistance alleles to Cry1Ab corn in the sugarcane borer, Diatraea saccharalis (F.) (Lepidoptera: Crambidae), were first detected in a field population in northeast Louisiana in 2004, and the estimated frequency of the resistance allele was 0.0177 in populations in …
