“The pink bollworm, a destructive insect pest of cotton that once required multiple insecticide applications while continuing to reduce yields, is no longer present in U.S. cotton production,” Adams said. “The benefits of this program are shared by society, the environment and the united producer membership who led this battle to victory.”. The pink bollworm, Pectinophora gossypiella (Saunders), is a key pest of cotton in the western United States, particularly Arizona, California, New Mexico, and west Texas. In recent years New Mexico cotton has been greatly impacted by pink bollworm and the boll weevil.
Arizona were estimated to exceed $ billion over the past thirty years (Roberson et al. , Antilla et al. ). Yield losses caused by PBW ranged from $$ per acre (Antilla et al. ). More recently, the National Cotton Council estimated that U.S. cotton producers’ annual losses to pink bollworm are about. Pink bollworm (plagued Arizona cotton crops until Pectinophora gossypiella) when Bt cotton was introduced. Containing a natural insecticide from the bacterium Bacillus thuringiensis, the transgenic crop preserves yields and protects farmworkers and the environment by reducing insecticide applications.
“Removing pink bollworm regulations eases the movement of cotton to market both domestically and internationally because farmers will have fewer restrictions to deal with, like fumigation requirements,” Perdue said. In a history of the infestations, USDA said, “Pink bollworm was first detected in the United States in Hearne, Texas, in dollars annually in control costs and yield losses; and. WHEREAS the United States Department of Agriculture has worked in close cooperation with state departments of agriculture in Arizona, California, New Mexico, and Texas; industry; and cotton growers over the last 18 years to find ways to finally eliminate pink bollworm from all cotton.

Such a program could use any combination of methods, including chemical control, cultural control, sterile releases, transgenic.Another insect pest that represents a serious threat to Arizona cotton production is the boll weevil.
Boll weevil infestations were first reported in Arizona in Santa Cruz, Pima, Pinal, Maricopa, and Yuma counties in and (Fye, ). Infestations have generally intensified with a gradual westward movement (Beasley and Henneberry, ).
