The Beltwide Cotton Insect Losses Survey has been supported by the National Cotton Council since 1979. This data is used to track state, regional and national trends in insect pressures and control measures. These trends are one tool that allow us to measure the impact of major programs (e.g., Boll Weevil Eradication programs) and new technologies (e.g., Bt cotton). These data are useful to policy-makers, bankers, marketing interests, insurers, regulators and researchers. These data are of particular importance to the development of regulatory policies to support special registrations, defense of pesticide products or uses, and to provide independent data to estimate pesticide/miticide use and insect-related losses.
Arizona Cotton Insect Losses Data
Therefore, the data provided here are modified from the original and may differ from non-adjusted original sources. It should also be noted that Arizona has historically grown two species of cotton (Pima and Upland). The Cotton Insect Loss reports used to produce these tables did not always explicitly state which species were being reported. From a review of the data provided, we concluded that both Upland and Pima acres were included in all years except 1987, 1994, and 1996-present, when Upland acres only were reported. Starting in 1999, non-Bt and Bt cotton estimates were reported separately. They are combined in the overall data, but are also available in separate tables.
How Data Are Collected
Data are collected through a series of interactive clientele workshops. Participants include Pest Control Advisors (PCAs), growers, industry representatives and Extension professionals. We work hard to enlist the participation of representative PCAs from throughout the appropriate growing regions, and follow-up with mail surveys to those who cannot attend, to develop the most complete and accurate dataset possible. Currently, the group develops data on cotton, head lettuce and melons, and is developing a pilot instrument for alfalfa.
