Knoxville, Tennessee hosted the 2012 annual meeting of the Entomological Society of America. The theme this year was A Global Society for a Global Science. Many of the sessions highlighted the latest research on how global change will impact insects as pollinators, pests of agricultural and forest systems, and vectors of disease.

Pollination biologists collect hundreds of bees every year to count and identify for important studies such as climate impacts on pollinator phenology (more on this in the future from Zak). Given significant concerns about global pollinator decline, it’s necessary to think about how collecting bees for these studies may affect native bee populations. The highly-anticipated results of Zak’s study are good news for scientists, as they suggest so far that the number of bees collected have negligible effects on bee populations.
I shared the Arctic perspective in a symposium titled “Aquatic Entomology as a Measure of Global Changes.”

The highlight was sharing my latest data on climate effects on mosquito abundance. Turns out, and consistent with local knowledge, a warm and wet spring ups the number of mosquitoes that survive to emerge. I also shared some preliminary data on mosquito fecundity, or how many eggs a female mosquito will lay. With the help of some very tolerant lab assistants, we counted the numbers of eggs in hundreds of mosquitoes collected from Kangerlussuaq this spring.
[The maximum number of eggs counted from one mosquito is… 122!]
