1.   Scientists at the seed company Nickerson International have produced a crop of potatoes which have been genetically modified to resist pests such as the Colorado beetle and tuber moth.

2.   Certain brands of vegetable oils and baking powder contain corn treated with a bacteria gene to resist pests.

3.   GM soy and corn, some of which are engineered to resist pests, produce greater yields with fewer chemicals.

4.   That organism, and its offspring, will then have a genetic structure that lets them resist such pests.

5.   The study was limited to crops that are modified to resist pests.
