Invasive Species- Pink Bollworm
Transcript of Invasive Species- Pink Bollworm
Pectinophora gossypiella The Pink Bollworm is a major pest in the Southern California Deserts but it can affect places all over the world. About the Pink Bollworm It is a native of India but has been reported from other parts of world where cotton is produced like US, Africa, Australia and Asia. Native Habitat Life Cycle In its adult, or moth, stage, the Pink Bollworm lays its eggs on cotton bolls. The eggs hatch into larvae that eat the cotton seeds and damage and discolor the fiber. Adult Stages The female moth lays eggs in a cotton boll, and when the larvae emerge from the eggs, they inflict damage through feeding. They chew through the cotton lint to feed on the seeds. Reproduction Adult Form- Adults are small, grayish brown, inconspicuous moths. Attack flowers of cotton Within a matter of days a cotton field can get infested with the pink bollworm The National Cotton Council of the USA estimates that the pink bollworm costs American cotton producers more than US$32 million each year in control and yield losses. In The USA The Pink Bollworm is found mostly in the Southwestern area and parts of California Most moths only live to about 10 days Strategies Being Used Today A newer strategy that has been used on cotton fields is a genetically engineered crop call Bt cotton. This type of cotton gives cotton a protein that kills some of the invasive insects but not all of them. It has been able to kill bollwormws before they can reproduce which helps lower their population. Eats cotton seeds Where do They Live? Pink Bollworms are usually found in the bolls of cotton plants Works Cited "How to Manage Pests." UC Management Guidelines for Pink Bollworm on Cotton. UC IPM Online, 2009.
