Humidity modifies age-dependent heat wave effects in an insect host-parasitoid interaction

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.
