Aphids, Wings, Fungus: A Tale of Many Experiments

We recently had a paper come out examining under what conditions aphids begin to produce winged offspring upon fungal infection (Tan et al. 2018). Following on a previous paper from another group suggesting that aphids produce winged offspring upon fungal infection, our research started as a rotation project by Wen Hao Tan to examine whether bacterial symbionts that protect against fungal pathogens would alter the response. Through a set of careful experiments by Wen Hao, Miguel Reyes and Kim Hoang, we show that aphids do produce more winged aphids after fungal infection…. sometimes. Why it happens sometimes and not others, despite our best efforts, is not yet clear. Fredrick Leon, an undergrad in the lab, is following up now.
