The pink bollworm (Pectinophora gossypiella; Spanish: lagarta rosada) is an insect known for being a pest in cotton farming.

The larva is a dull white caterpillar with eight pairs of legs[1] with conspicuous pink banding along its dorsum.

The USDA announced in 2018[2] that it had been eradicated from the continental United States, through the synergistic combination of using transgenic Bt cotton and releasing sterile males.

[4] Monsanto has admitted that this variety is ineffective against the pink bollworm pest in parts of Gujarat, India.

Once a crop has been harvested, the field is plowed under as soon as possible to stop the life cycle of the new generation of pink bollworm.
