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 with Biorender.com.
