A: All plants genetically modified to be insect resistant or herbicide tolerant undergo a risk assessment, which includes evaluating potential adverse impacts on nontarget arthropods (insects and related animals). Major groups tested include pollinators (e.g., honey bees and bumble bees), predators (e.g., lady beetles and green lacewings) and parasites (e.g., Diaeretiella rapae, an aphid parasite). In addition, soil-dwelling animals, like earthworms, isopods, Collembola, nematodes and protozoa,... Continue Reading

A: This question includes an interesting observation and is one that every country that grows GM crops asks. Regulating agencies are very interested in making sure GM crops are compositionally the same as non-GM and that the gene does not negatively affect the plant. As you point out, honey production is an important aspect of canola production, and thus companies make sure that the plants used to develop GM varieties will still produce nectar. Canada is the second-largest grower of canola (the... Continue Reading

A: Thank you for your question. First, the insecticidal protein the crop produces is very specific to particular insect orders. For example, the Bt protein Cry1Ab affects only specific caterpillar (the order Lepidoptera) pests, while the Bt protein Cry3Bb1 affects only specific beetle (the order Coleoptera) pests. This specificity is one of the reasons Bt is such a popular insecticide in both GM crops and non-GM crops, including organic agriculture. Thus, the Bt proteins currently being used in...

A: Genetically modified (GM) plants and their impact on honey bees have been widely studied, and the results indicate that GM plants are not harmful to bees. A review by Malone and Pham-Delègue (2001) looked at seven studies. Their conclusion was that “Bt transgene products are very likely to be safe for honey bees and bumblebees.” One large study, by Duan et al. (2008), looked at 25 different studies and concluded that “the Bt Cry proteins used in genetically modified crops for... Continue Reading
