Fertile female pink boll worm, Pectinophora gossypiella (Saunders), moths released in field cages over cotton plants at Phoenix, Ariz., 20 May to 3 June did not initiate larval infestations in squares, even though viable eggs were laid; however, few squares and no bolls were available as host material. Square and boll infestations were initiated when fertile females were released in field cages periodically between 17 June and 22 July when cotton plants had 9.4 or more squares per plant and bolls were available as host material. Days to first moth emergence were significantly higher for moths from eggs laid in mid- June (31 d) than for moths from eggs laid in late June and July (23-27 d). Pink boll worm moth emergence patterns were highly variable, and moths from eggs laid 17 to 24 June, 1 to 4, 8 to 11, 15 to 18, and 22 to 25 July emerged in each case over a 26-d period following the first emergence, even though all oviposition occurred during 3 d. This resulted in significant overlap of moth emergence from each artificially-induced infestation, even though the time between initiation of the first and last infestations in cages was >30 d.
