Diamondback moth caterpillar grows better on transgenic crops
March 31st, 2003
Researchers from Imperial College, England, report that toxin-resistant larvae of the diamondback moth, an agricultural pest, developed faster and had a greater pupal weight in the presence of an engineered toxin. Their study was published in the journal Ecology Letters (March 2003; 6(3)). The researchers say the caterpillars, the larval stage of moths and butterflies, can use an engineered toxin (Cry1Ac) as a supplementary food source. This could be a genetic effect, they said, linked indirectly to the presence of a resistance allele, but more simply could be due to resistant insects enhancing their ability to survive and digest the...
