Abstract Development of transgenic Bt crops with stable and high level of Bt protein expression over generations under different environmental conditions is critical for successful deployment at field level. In the present study, progenies of transgenic cotton Coker310 event, CH12 expressing novel cry2AX...
Preliminary bioassays with whole cultures (WC) of 124 Bacillus thuringiensis strains were performed with neonate larvae of Anthonomus grandis, a major cotton pest in Argentina and other regions of the Americas. Three exotic and four native strains were selected for causing more than 50% mortality. All of...
A total of 268 Bacillus thuringiensis strains obtained from different sources of Argentina were analyzed to determine the diversity and distribution of the cryl, cry2, cry8, cry9 and vip3A genes encoding for lepidopteran-specific insecticidal proteins. Twin strains were excluded. Ten different profiles w...
Susceptibility of populations of Simulium (Chirostilia) pertinax Kollar, 1832 (Culicomorpha, Simuliidae) to temephos and to Bacillus thuringiensis var. israelensis formulation
O uso de pequenas calhas de madeira no leito de riachos, manualmente colonizadas com borrachudos, é proposto para avaliaçöes da eficiência de larvicidas 3 ou 4 horas após as aplicaçöes. A susceptibilidade larval também foi avaliada pelo critério de TL50. Em três ensaios no litoral do Estado de ...
A susceptibilidade de larvas de Aedes aegypti coletadas no campo foi avaliada em termos do tempo letal mediano (TL50) e da mortalidade final, quando tratadas com temephos, Bacilus thuringiensis var israelensis ou misturas desses dois agentes. As larvas de terceiro estádio mostraram-se mais susceptíveis...
