Some of the fields treated with ULV malathion in Central Arizona had more beet armyworm, Spodoptera exiqua-damaged squares than untreated fields, but more than 60 % of the fields had damage levels that were < to the untreated fields. Boll weevils were detected by square sampling before traps indicated their presence in some fields and this phenomenon ranged from 0 to 42 % in the 3 areas sampled. The population ranged from 0.2 to 0.4 boll weevils per trap from July 8 to Aug. 6. Whitefly populations were similar in treated and untreated fields with significant differences occurring only on one date.
