Moth mating performance.

Initiation of mating between (a) sentinel wild type [APHIS or University of Arizona (UoA)] female moths and released OX1138B, APHIS males or wild males present in the field; and (b) sentinel OX1138B or APHIS female moths and wild males. Initiation of mating was defined as a male and female joined together in the tail-to-tail position typical of mating in Lepidoptera. Wild males also initiated mating with the females in this experiment: three on 26 July, 2007, four on 3 August, 2007 and 59 males on 15 September, 2007 (the high number on this last date reflects the typical wild pink bollworm recapture in traps late in the growing season).
