Seems this is could be a direct result of warming:
"The Asian form, Ca. L. asiaticus is heat tolerant. This means the greening symptoms can develop at temperatures up to 35 °C. The African form, Ca. L. africanus, and American form, Ca. L. americanus, are heat sensitive, thus symptoms only develop when the temperature is in the range 20–25 °C."
- mcculley 3y agoI don’t understand how this follows. The Asian form could develop at temperatures less than 35°C also, right?
- ramesh31 3y agoPoint being the American form is the issue in Florida. Warmer winters means more time spent at 20–25°C, increasing the overall disease burden.
- mcculley 3y agoI still don't understand how you arrive at this conclusion. I just did a quick pivot table of the data for 1901-2021 for Ft. Pierce, Florida, the region with which I am most familiar regarding the greening crisis. While the mean temperature has been increasing, the days spent between 20-25ºC seem to have no clear trend.
