Table 4.

Larval rearing conditions used in the factorial experiment.

Treatment	Rearing condition	Temperature (°C)	Food/density ratio1	Larvae per tray
1	Reference	24	0.5	150
a	High temperature	32	0.5	150
b	High food	24	2.0	150
c	High density	24	0.5	600
ab	High temperature, High food	32	2.0	150
ac	High temperature High density	32	0.5	600
bc	High food, High density	24	2.0	600
abc	High temperature, High food High density	32	2.0	600

¹The food ratio indicates the ratio of the amount of food fed to the larvae as compared to the standard rearing conditions (Table 3). In the reference treatment all factors were set at the lower levels.
