If anything, acute hazard shrank while chronic hazard stayed the same.

I have no clue why this is, but I do find it interesting.

In sweet cherries, we see a completely different pattern.

No bump in insecticide application after SWD introduction.

This dataset is also from Michigan, BTW.

Not surprising. You handle insect problems with insecticides.

What surprised me was that the acute hazard actually stayed the same for awhile after the introduction of SWD to Michigan.

Chronic hazard spiked, thanks to the increased application of Chlorpyrifos.

So enter cherries, and we're starting with tart cherries.

SWD is a major pest in cherries.

After SWD was detected in Michigan, growers responded by increasing applications of insecticides to their fields.

A really great pest to explore this with is Drosophila suzukii, or SWD.

SWD lays eggs inside ripening fruit, causing the fruit to become unsellable.

SWD was introduced in 2008, and since then has become a $500 million a year pest.
