    GM pink bollworms are a prelude to developing female-killing traits to control bollworm pests. Dr. Mae-Wan Ho and Prof. Joe Cummins explain the genetics and hazards of female killing systems. The female-killing systems developed out of the sterile insect technique (SIT), which has been used in biological pest control since the s. Among the bollworms, the pink bollworm assumed a major pest status in the recent past (Ghosh, ). World over, pink bollworm P. gossypiella has become economically the most destructive pest of cotton and has known to cause –% loss in seed cotton yield, –% loss in oil content and –% loss in normal opening of Cited by: 4.

    The pink bollworm is distributed in many cotton-growing countries, including India, Iran, Afghanistan, Turkey, Japan, China, Korea, Greece, and Italy. The insect does not occur in the USSR, where it is an object of external quarantine. The pink bollworm produces two to six generations per year. Pink Bollworm Management In Texas Charles T.
