For each of the four tests (12 days at B1.1°C
(test 1), 16 days at B2.2°C (test 2), or 14 days at
B1.67°C (tests 3 and 4)), exposure of infested
fruit to a temperature spike (pulp at 4.489
0.28°C, for 1 h) during the treatment had no
effect on survivorship of C. capitata eggs when
the fruit were subsequently allowed to complete
the required treatment protocols. No eggs or larvae
survived regardless of whether the temperature
spike occurred on day 6–9, and regardless of
which protocol was used, as long as the treatment
was allowed to resume treatment at the required
temperatures and times until completion. No tests
of temperature spikes on days earlier than day 6
were conducted, since it was deemed reasonable
that if a spike occurred early in the treatment
