Cotton bollworms are a significant pest of cotton. [1] "A major pest in hot countries of irrigated crops. Enters into a summer diapause when irrigated crops are not present and the soil and air temperatures are high. When the end of the dry season comes, the rain cools the soil and pupae come out of diapause." (Nibouche 2004)

The cotton incorporated the cry1Ac gene from the soil bacterium Bacillus thuringiensis (Bt), making the cotton toxic to bollworms. This variety showed poor yield, was removed within a year, [when?] and contained a DNA sequence owned by Monsanto, prompting an investigation. [16]
They chew through the cotton lint to feed on the seeds. Since cotton is used for both fiber and seed oil, the damage is twofold. Their disruption of the protective tissue around the boll is a portal of entry for other insects and fungi. The pink bollworm is native to Asia, but has become an invasive species in most of the world's cotton-growing ...
