Interpretive Summary: Each cotton growing season, the first generation of PBW developing from eggs laid by moths from overwintering diapause larvae occurs in cotton flower buds. The larvae mature about the time of anthesis. The mature larvae, prior to tunneling out of the flower to pupate in the soil, frequently tie flower petals together to form the PBW characteristic “rosetted bloom”. Opening “rosetted blooms” often reveals PBW larvae feeding on cotton flower anthers.
