10. Sterile Moth Release - Southern California Southern California added to USDA Pink Bollworm Area-wide Eradication Program: Imperial, Riverside, and San Bernardino counties Program elements: insect monitoring, Bt cotton plantings, sterile insect release, and pheromone treatments in non-Bt cotton (Two Research Field Plots) “THANKS to USDA Section 18” Blythe/Palo Verde and Imperial Valley cotton growers planted 100% Bt cotton Mass aerial sterile moth release conducted by USDA Over 32 million sterile moths released

13. Bt Resistance Monitoring Southern California

14. 10 sites: 4 IV and 6 B/PV –1,000 bolls from Bt cotton fields –200 bolls from non-BT (Bard/Winterhaven) Imperial Valley collected 4,400 bolls Blythe/Palo Verde Valley collected 6,000 bolls No resistance observed to date Bt Monitoring Statistics
