Abstract
Climate change is projected to increase the likelihood of extreme heat events, but it may also increase humidity levels, leading to the potential for coupled thermal and hydric stress. While increasing frequency and intensity of extreme heat events have been well-documented for their negative effects on species and their interactions, how humidity modulates the impacts of heat stress is currently unknown.
We investigated how humidity interacted with heat stresses of different timings and durations to affect the life histories in an insect host-parasitoid interaction, comprising the Indian meal moth, Plodia interpunctella, and its endoparasitoid wasp, Venturia canescens. Hosts parasitised as 4th instar larvae and unparasitized hosts were maintained in a high humid (60.8% RH) or low-humid (32.5% RH) environment at a constant temperature of 28℃. They were then exposed to 38℃ thermal stresses with a duration of 6 or 72 hours in either the 4th or 5th instar.
Humidity and heat stresses did not affect the adult emergence of unparasitized hosts, but longer heat stress and lower humidity increased the probability that host adults emerged from parasitized hosts, indicating the negative effect of these conditions on the survival of parasitoids. Furthermore, juvenile development time and body size of hosts and parasitoids responded differently to timing and duration of heat stresses, and high humidity decreased larval development time of unparasitized hosts and increased the size of both hosts and parasitoids. In addition, humidity negatively interacted with larval stage and duration of heat stress to affect the size of unparasitized hosts, but this effect was not found in parasitoids.
Our results show that humidity modulates the life history of hosts and parasitoids, highlighting the importance of humidity in maintaining host-parasitoid interactions. Humidity should be considered when predicting the impact of temperature extremes on species’ population dynamics and their interactions.

Description of the data and file structure
This contains two data files:
Host.csv---life history measures of the host.
Parasitoid.csv - life history measures of the parasitoid.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Within each data set, there are several columns indicate different treatments and measures for each individual of host and parasitoid:
Plate_id
: the id of 25-well plate used for the experiment.
Id
: unique id of each individual larvae.
Parasitism
: Whether hosts are parasitized by parasitoids. H = host alone, HP = hosts were parasitized by parasitoids.
Duration
: Duration of heat stress i.e., 0, 6, 72 hours. Unite = hour
Stage
: Host stages when heat stress exposed i.e., L4 = 4th instar, L5 = 5th instar.
Eggtransfer_date
: The date when eggs were transferred into plates i.e., the first day of observation. Unit = date.
Survivived2L4
: If individual host larval has survived to 4th instar. 1 = yes, 0 = no.
Pupate
: If individual host larval has successfully pupated. 1 = yes, 0 = no. NA when hosts did not survive earlier.
Hostpupate_date
: When hosts were first observed as pupated. NA when hosts did not survive earlier. Unit: date
Hostemergence/Wasp_emergence
: If individual host/parasitoid adult has successfully emerged. 1 = yes, 0 = no. NA when host/parasitoid did not survive to this stage.
Hostemerge_date
: When host adults were emerged. NA when hosts did not survive earlier. Unit = date
Hostdead_date
: When host adults were recorded dead. NA when hosts did not survive earlier. Unit = date.
Host_sex
: The sex of host i.e., M= male, F = femal. NA when hosts did not survive earlier.
Midfemur
: The mid-femur length of host adults. NA when not applicable. Unit = mm.
Rearfemur:
The rear-femur length of host adults. NA when not applicable. Unit = mm.
Wasp_size
: The hind tibia length of parasitoid. Unit = mm.
