The internal house temperature was measured by
maximum-minimum temperature thermometers placed

house. The following average temperatures were recorded
during the experiments: 25°C (22 and 28°C for
the minimum and maximum, respectively) for 8 to 21 d
and 25°C (21 and 29°C for the minimum and maximum,
respectively) for 30 to 43 d.
