Long-term increased cost to the Michigan potato industry caused by insecticide resistance in Colorado potato beetle was estimated at $0.9 to $1.4 million each year.

However, many chemicals are often unsuccessful when used against this pest because of the beetle's ability to rapidly develop insecticide resistance. Colorado Potato Beetle Life Cycle .

The last major outbreak was in 1976. Basically, it's the study of how environmental stresses—from starvation to air pollution to pesticides—can add or remove chemical tags to an organism's DNA—flipping a genetic switch that changes its health and behavior.

BEETLES INDEX. DNA methylation was first shown to occur in human cancer in 1983 and since the early 2000s the epigenetics revolution in biology began to reveal how environmental change can turn certain genes on or off, leading to profound changes in an organism without changing its DNA. Native to the Rocky Mountains,[3] it spread rapidly in potato crops across America and then Europe from 1859 onwards. These voracious insects can be confused with false potato beetles (Leptinotarsa juncta), which are not pests.
