Interpretive Summary:

Technical Abstract: In conjunction with a comprehensive study assessing the quality of whitefly management based on different insecticide regimens (Ellsworth, Section F), responses of whiteflies to Danitol+Orthene in a yellow-sticky card bioassay were measured pre-, mid-, and post-spraying at the experimental site in Maricopa, AZ. Adult whiteflies tested in the bioassays were collected from meach of four insecticide treatment regimens, replicated four times, that partitioned the 8-acre study field. Insecticide regimens were as follows: 1) Knack first, followed by Applaud and two non-pyrethroid combination sprays; 2) Applaud first, followed by Knack and two non-pyrethroid combination sprays; 3) 'IRM', consisting of three non-pyrethroid sprays and two pyrethroid sprays (Danitol+Orthene and Danitol+Vydate; 4) 'UTC', untreated control.
