Book excerpt: Excerpt from Pink Bollworm-Gossyplure Studies in the Palo Verde Valley, California Growers and pest-control advisers, in consort with representatives of the pheromone companies, made all decisions regarding initiation, frequency of application, and time of termination of pheromone and insecticide treatments. For convenience and economy, several fields within some treatment regimes were often block-treated (for example, two to four contiguous fields out of six for some of the treatment regimes were often aerially treated across rows without interruption). This arrange ment negated a completely randomized design; however, for the purposes of analyses, we assumed that fields were Trap Studies randomized within treatments. Thus, unless otherwise stated, the basic analysis was a one - way analysis of variance with five treatments: nomate nomate pew( Disrupt( and insecticides only. Six fields within each treatment served as replications. Some analyses also included quadrants as a split - plot factor. In order to remove time as a source of variation in the analyses, data were averaged over sampling dates; however, to examine seasonal changes in param eters monitored, certain data were plotted against time. Analyses were performed on data sets where no esti mates for missing values were included and on those where estimated values were included. Also, data were ana lyzed after transformations were performed for both data sets. Minor differences in mean values were noted between analyses; however, neither ranking of means nor their significant differences changed as a result of including estimated values or data transformations.
