Description of the experimental treatments employed to test the effects of elevated temperature at various stages of preimaginal development in Harmonia axyridis.

*The first larval instar in H. axyridis subsists for a shorter time than 48 hours at 33°C, therefore it was necessary to make pooled treatment for the 1st and 2nd instars (see Table S1).*在33℃条件下，异色瓢虫（Harmonia axyridis）的1龄幼虫发育历期短于48小时，因此需对1龄与2龄幼虫开展合并处理（详见补充表S1）。
