Cotton bollworm
Appearance
Cotton bollworm is a problem in growing cotton. "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)
