Performance of transgenic maize genotypes against ear caterpillars in Argentina
Maize (Zea mays L.) is one of the most widely cultivated crops in the world and Argentina is a leading producer worldwide. Lepidopteran pests such as the fall army worm (Spodoptera frugiperda -J. E. Smith-) and the corn earworm (Helicoverpazea -Boddie-) cause ear damage, producing yield losses and...

| Sumario: | Maize (Zea mays L.) is one of the most widely cultivated crops in the world and Argentina is a leading producer
worldwide. Lepidopteran pests such as the fall army worm (Spodoptera frugiperda -J. E. Smith-) and the corn
earworm (Helicoverpazea -Boddie-) cause ear damage, producing yield losses and facilitating the entry of pathogenic
fungi such as Aspergillus flavus. Under conditions of high temperatures and drought stress,some Aspergillus
strains can produce Aflatoxin B1 (AFB1), which is highly carcinogenic for humans and animals. The main aim of
the current study was to determine the performance of PowerCore®, PowerCore® Ultra and Genuity® VT triple
PRO®Bthybrid maize to corn ear caterpillar damage in Santiago del Estero, Argentina. Since 1990,the agricultural
land area in this province has increased due to the forest clearance for agriculture. Climatic conditions in the
region are favourable for aflatoxin. PowerCore® Ultra showed the highest yield and, PowerCore®registered the
lowest severity of damage by corn ear caterpillar. The correlation between yield and insect damage severity was
negative under the conditions evaluated. |
