In previous papers, we have shown that the urban heat island effect can increase pest abundance on trees. Oak lecanium scales become more abundant due to greater survival on hot trees. Gloomy scales become more abundant because on warm trees more of them survive and they produce three times as many eggs.In a new paper, Adam Dale (former PhD student now at University of Florida), shows that drought, in addition to heat, is also an important mechanism by which gloomy scale abundance increases on urban red maples. This is among the best evidence that heat and drought – two major consequences of urbanization and of climate change – combine to benefit pests and thus must be studied in concert. Read more about it in Adam’s blog post.
