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.
Introduction and Background:
Arizona Cotton Insect Losses Data
The data presented here reflect historical insect losses in Arizona cotton.
These data are based on yearly estimates reported by state Extension entomologists,
compiled by the Cotton Insect Loss Committee and presented at the annual
Cotton Insect Research and Control Conference (http://www.msstate.edu/Entomology/Cotton.html,
See References for original printed references). These estimates are derived
from grower and PCA responses to a standardized survey, and/or expert
opinion. Reporting methods and the information provided have been evolving
since 1979 and in order to provide the most useful data, the data were
made comparable through time. These data were standardized by:
- combining some species,
- reporting infested and treated acres as percentages,
- calculating loss figures using historical lint prices provided by
NASS (National Agricultural Statistics Service, http://www.nass.usda.gov/),
- adjusting Statewide Economic Loss figures (for yield and for control)
to reflect bale production as reported by NASS,
- obtaining cost per application data from University of Arizona County
Crop Budgets from 1979-1985, and
- deriving new data of interest.
- For details.
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
Starting in 2003, with funding from the Western IPM Center, the Crop Insect Losses and Impact Assessment Working Group was formed to refine and improve the data collection process for cotton losses in Arizona, and to expand this process to collect comparable data for other crops in Arizona and in adjacent low desert regions of California. Subsequently, we received funding as a Signature Program of the Western IPM Center, and are working to promote adoption of similar surveys and processes in other crops and states to help document the outcomes and impacts of IPM.
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 and head lettuce in Arizona and in adjacent low desert regions of California.
