Emergence of sexual size dimorphism and stage-specific effects of elevated temperature on growth rate and development rate in Harmonia axyridis

Popis výsledku v původním jazyce

Temperature is considered to be the most important environmental factor influencing performance of ectotherms, as it determines the rate of most biochemical reactions and thus metabolism efficiency and function. Unfortunately, the majority of studies investigate effects of temperature on individuals exposed to a particular temperature regime during their whole preimaginal development and detailed information on variation of the temperature effects during ontogeny is rare. Here the effects of timing of exposure to a transient period of elevated temperature during ontogeny on development rate and growth rate are investigated for a ladybird Harmonia axyridis (Pallas, 1773). Control beetles were reared at a constant temperature of 20 °C, whereas treated beetles were reared at 20 °C, but were exposed to 33 °C for 48 h either during the early larval stage, third larval instar, fourth larval instar or the pupal stage. The rate of development and the growth rate were accelerated as timing of e
