Bt Corn, Potato

2.     Bt resistance genes found in the wild populations of moth

Scientists at the University of North Carolina in the U.S. have already found Bt resistance genes in wild populations of a moth pest that feeds on corn (Gould et. al, 1997). The resistance concerns are serious enough that, just last month, a coalition of the US' major producers of genetically engineered corn seed, under pressure from federal regulators, environmentalists and the weight of scientific studies, said they would require farmers to grow sizable plots of non-engineered corn in an effort to stave off resistance (Weiss, 1999).

Initial frequency of alleles for resistance to Bacillus thuringiensis toxins in field populations of Heliothis virescens. Proceedings of the National Academy of Sciences, USA, 94: 3519-3523.

3.     Reduced the population of non-targeted insects , greenlacewigs

Researchers from Swiss Federal Research Station for Agroecology and Agriculture, for example, found over 60% mortality among green lacewings larvae (a major predator of corn pests) that ate moth larvae that had fed on Bt corn (Hilbeck et al., 1998).

Hilbeck, A., Baumgartner, M., Fried, P.M. and F. Bigler. 1998. Effects of transgenic Bacillus thuringiensis corn-fed prey on mortality and development time of immature Chysoperla carnea (Neuroptera: Chrysopidae). Environmental Entomology, 27(2): 480-487.

Furthermore, the increased lacewing mortality was seen regardless of whether it ate sick prey (i.e. poisoned by eating Bt) or healthy (i.e. resistant to Bt) prey. Bt-resistant insects could feed on Bt corn, fly off to other plants, and be eaten by lacewing which would then die. The resulting ecological effects could extend well beyond the borders of the area planted to transgenic crops.

Other studies have shown that the Bt toxin can persist in soils for over forty days (the longest time evaluated) and can retain its toxicity to insects (Koskella and Stotzky, 1997).
