Abstract
Stress experienced during embryogenesis can have long-lasting effects. These effects may be particularly pronounced in hemimetabolous insects, given that they do not undergo body reorganization prior to adulthood. Here, we examined the effects of maternal exposure to different temperatures (19 °C, 22 °C, 25 °C, 28 °C, 31 °C) in live-bearing, asexual female pea aphids (Acyrthosiphon pisum). Specifically, we reared pea aphid mothers at these different temperatures, transferred their offspring to a common permissive temperature of 19 °C, and subsequently measured offspring developmental time, adult morphological traits, and fecundity. We found that pea aphids largely did not survive to adulthood at 31 °C, so we were not able to examine their offspring. For the remaining temperatures, offspring whose mothers were raised at 19-25 °C had largely similar trait values, while those whose mothers were raised at 28 °C developed significantly more slowly, had smaller body parts, and had lower fecundity. Our results demonstrate that in this hemimetabolous insect, the effects of embryonic exposure to temperature (either indirectly via the mother or directly from the environment) persist into adulthood.

Description of the data and file structure
Table S1 contains the data needed to recreate Figures 2 and 4 in the associated article. It contains the following columns:
Sample = unique pea aphid ID
Maternal Temperature = temperature in which the mother was raised
Temporal Replicate = 1 or 2; the experiment was repeated 2x
Spatial Replicate = different plants in the same incubator at the same temperature
Days in first, second, third, fourth instar = time spent at each stage
Days to adulthood = total time to adulthood
Phenotype = adult phenotype, winged (W) or wingless (WL); W individuals were not used for analyses
Total days to reproductive maturity = days until mother gave birth to first nymph
48 hr fecundity = how many nymphs mother gave birth to in first 48 hours of reproduction
Mature embryo count = after ovaries were dissected out of the mother, how many embryos had red eyes
Table S2 contains the data needed to recreate Figure 4.
All columns are as described for Table S1 or as described in the methods for morphological traits.
In both files = NA means there was no information for that value.
