• 1983 Pre-Season Trap Catch of Boll Weevil (Coloptera: Curculionidae) in Western Arizona Including a Comparison with the 1982 Catch

      Worth, P. W. (College of Agriculture, University of Arizona (Tucson, AZ), 1984-02)
      An adult boll weevil (Anthonomus grandis complex) trapping network was organized in the major cotton producing areas of western Arizona for the first four months of 1982 and 1983. The results for each year are summarized as the mean number of adult boll weevils caught per grandlure baited trap and adjusted for the number of days each trap was in operation. Where possible, the 6 major cropping areas were subdivided into trapping sectors which permitted more detailed analysis. The results indicate the boll weevil expanded its range in western Arizona between 1982 and 1983. In 1982, they were trapped in 432 of the sectors and in 1983, 96% of the sectors. The results also show an increase in population size between 1982 and 1983. The mean number of boll weevils BW caught per trap per day was 1 to 291 times greater in 1983 depending on trapping sector.

      Two insecticide applications were made to cotton in late August and early September. Higher Bemisia tabaci populations were observed in the malathion treatment, as sampled by vacuum samples, and in the DyloxR and malathion treatments, as sampled by yellow sticky traps. Generally, the numbers of parasites collected were higher in untreated check plots than in the insecticide treated plots.
