Life stage-dependent effects of experimental heat waves on an insect herbivore
Ecological Entomology 40 (2), 175-181
Abstract: 1. Worldwide concern about the consequences of climate change has prompted efforts to understand and predict the responses of populations to changes in temperature.
2. A heat wave can adversely affect organisms, may affect different life stages differently, and could decrease populations. In this study, green peach aphid [Myzus persicae (Sulzer)] nymphs, reproductive adults, and late-reproductive adults were exposed to a heat wave, defined as 5 °C above the control temperature regime for five consecutive days.
3. The negative effects of experimental warming on development, reproduction, and survival negatively affected population growth. Nymphs and reproductive adults were more severely impacted than late-reproductive adults.
4. Experiments designed to mimic temperature regimes can assess the direct effects of climate change on individuals and populations. Our study highlights the importance of assessing the life stage-specific responses to heat stress.
