Jumping Jehoshaphat, the grasshoppers have arrived!

In the news…

I’m wondering if anyone is following the grasshopper outbreak in Oregon? If you don’t know about this, I’ll fill you in and include some links. Perhaps we need to round up our “mean-ole, hummingbird murdering mantids” (EXTREME SARCASM HERE!) and send them south to help out. Just kidding. If you read through the attached list of sources, you’ll see in one where they’ve now determined the mantids don’t have much of an impact on controlling grasshoppers (Fries, 2021).

If they are so bad (and from historical reports, they can indeed reach proportions on the scale of a Biblical plague), what do we do about them? Why is there such an outbreak?

Grasshopper populations cycle periodically, but it’s thought they are worst when conditions are dry. One theory is that a fungus that controls populations isn’t viable in these conditions and only works when we have damper weather.

Historically, control methods have been pretty toxic – everything from arsenic bait to other drastic measures – all environmentally hazardous. If you review old agricultural journals, records of exploding grasshopper populations conjure up images of something you’d see in a horror movie, only it was real. Historical photos exist of a landscape stripped of vegetation; bare fields and trees. Handles were eaten off wooden farm implements and fenceposts were eaten too. Crops were lost, people starved. There’s a reason it’s called a PLAGUE. 🦗🦗🦗

So, this is happening now in Oregon. Aphis is coordinating aerial spraying of wide swaths (millions of acres ) of land with an insecticide called diflubenzuron. Studies have shown diflubenzuron reduces populations of bees, butterflies, beetles, and many other species of insects. Aquatic invertebrates consumed by endangered fish and trout are also vulnerable (Xerces Society, 2022). Xerces Society has a federal lawsuit against Aphis to fight this grasshopper managment strategy. Application of this insecticide directly threatens endangered species like yellow-billed cuckoos, black-footed ferrets, bull trout, Ute ladies’-tresses orchids, Oregon spotted frogs and Spalding’s catchflies which are present in multiple states in which the insecticide spraying program operates (Xerces, 2022).

What can we do if we don’t spray? Well, I would encourage folks to look at the studies about the benefits of eating grasshoppers. They aren’t much different than shrimp. At a minimum, they could be netted, dried, and manufactured into feed for poultry, fish, and swine. We have to stop the madness. Dumping chemicals is only bringing our apocalypse closer. We won’t survive. The grasshoppers probably will. 🦗🦗🦗🦗🦗🦗🦗
