Figure 1 Schematic diagram of the experiment. Host eggs were
placed in either a humid or non-humid incubator at a constant
temperature of 28 ℃ until they reached the early 4thinstar. Half of the hosts were parasitized whilst the other half
unparasitized. Both parasitized and unparasitized hosts experienced a 38
℃ heat wave either as early 4th instar or
5th instar larvae. After exposure to the heat wave,
all the hosts were kept at constant 28 ℃ until adult emergence. Credit
