Pink Bollworm Situation in the Trans-Pecos Area of Texas 



Pink Bollworm (Pectinophora gossypiella ) .populations have continued to build up 

 in the central and Trans-Pecos areas. Infestations generally widespread in Martin, 

 Midland, and Glasscock Counties and Bakersfield area of Pecos County in Trans- 

 Pecos area. Infestations in the Coyanosa area, and westward into Reeves and other 

 cotton-growing counties of Trans-Pecos were noted as being isolated and scattered. 

 During September, increase was noted, but these populations began to build up 

 later this year than in previous years. Most of the cotton in the Trans-Pecos 

 area is 60-70 percent open now, so late bolls in the field are subject to attack. 

 In Midland and Glasscock Counties, and in the Bakersfield area of Pecos County, 

 cotton is still blooming and it is not uncommon to find 10-15 percent resetted 

 blooms in this area. 



Widespread infestations have been noted in central areas. Hill, McLennan, Bell, 

 and Milam Counties have had heavy populations during September. Cotton in these 

 areas is about 75 percent harvested and pink bollworms are being found in the top 

 bolls. Heavy populations were noted in Hardeman County near Chillicothe. 



Pink bollworm populations are general throughout the north-central area. (Green 

 et al.) .
