Performance of pink bollworm moths, Pectinophora gossypiella (Saunders) was evaluated in 2 fields near Laveen, AZ. Pink bollworm were reared on artificial diet at 2000 and 4000 eggs per rearing cell to obtain differences in moth size, for this study. Resulting moths were marked with different colored external dyes and released in the early evening. Moths were released weekly for 5 weeks and moth recapture rate and longevity were recorded. Implications of pink bollworm moth performance based on size are discussed.
