In a recent article, ‘Big Farmer’ Firms Plan Pesticides to Manipulate Gene Expression a new pest control technology may be available in coming years. The technology is based on a process called RNA interference, or RNAi. RNAi affects gene expression in pests, without modifying crop genes. One advantage is that it would allow farmers to target pests, without the potential to harm other species. “By using sequences of RNA that match specific gene sequences in a pest, RNAi should leave other species unscathed.”
However, targeting unique genes versus shared genes within species could prove to be difficult. Click here to read more about RNAi.
