Where Agriculture and Horror Movies Collide

Have you watched the movie “Alien” where a creature bursts out of the chest of a human, killing him? Truth be told, I am not a fan of horror movies. However, when similar things happen to insects in nature, I am totally fascinated!

Starting today, one of our soybean fields will have little wasps that act like the Alien. They sting soybean aphids, and lay their eggs inside the aphid. This kills and mummifies the aphid. When the larva is ready for the next stage of life, it bursts out of the mummified aphid body. So cool!

So, what do these vicious creatures look like?

Did you see it? Maybe this extreme closeup will help…

Yep, these tiny little wasps are the size of a soybean aphid…which is about as big as the dot of a Sharpie Fine Pen. Nick, a doctoral student from the University of Minnesota entomology department came out today to distribute 75,000 of these little buggers. They arrived in their shipping containers, which were mummified soybean aphids on soybean leaves. The black dots are the aphids which house the wasps…

Nick transferred the wasps, leaves, and larva to a slightly larger cup, making sure he had a similar amount of wasps in each cup (yes, someone had figured out how many there were in each cup). He then put a mesh over the top that was large enough for the wasps to go in and out, but not large enough for predators like lady beetles to get in. These cups were put in milk crates as a base of sorts for the wasps.

Nick then went walking on the edge of the field, flagging locations for the six crates to be placed. After that he measured out about 2 meters in each direction, and placed another flag. The soybean plants by those flags will be checked in 3 weeks to see if the wasps have moved that far from their point of release.

One of the limiting factors in this research is the amount of soybean aphids currently in our fields. When we were looking, we really didn’t find many at all. This is due to the delays in planting, and the cooler weather that has slowed the growth of the soybeans. Nick was explaining the optimal time for aphid movement according to soybean plant stage, and encouraged scouting within the next two weeks.

Jonathan and I are pretty interested in learning more about how this natural aphid control will work in a real world situation. We are hoping that this will turn into a viable tool that we can use to combat the soybean aphid. Right now, as organic farmers, we have no effective method to control them other than planting naturally aphid tolerant varieties of soybeans. Nick is hoping that the wasps that were released today will not only help us this year, but their future generations will be helpful in the years to come.

How cool is it that scientists have found an Alien like way to control an agriculture pest?

 

 

30 Days of Thanksgiving – Day 5: Flowers

CarolynCares Roses

You’ve heard the phrase, “Take the time to stop and smell the roses”, right? How many of us actually stop to admire flowers when rushing from one commitment to another?

I am so thankful for the huge variety in flowers that we are able to enjoy. As much as they annoy me, even Dandelions can be beautiful when looked at through a macro lens. The thing is, you need to stop long enough to see the beauty. Kind of like other areas in our lives. If we keep rushing around with our heads down, we miss out on the beauty that surrounds us. If you are feeling a little bit down, a bouquet of flowers can cheer you up. They come in so many colors, shapes, and sizes. You don’t have to spend a fortune to add a little sunshine to your dining table, or your cubicle. Jonathan will buy the little $5 bundles from the grocery store when I’ve had a tough day, and I love them!

My challenge to you this week, is to take a look at things from a different perspective. Stop and look around at the fall decorations, the mums in flower gardens, the brilliant blue of the fall skies, the people in your office. Find the beauty. Your life will be richer for it.

Follow along with other 30 Day Challenge Bloggers by heading over to Holly Spangler’s blog. She keeps an updated list of participating blogs.

Blizzards and Caring for Livestock

We were hit with a blizzard warning this weekend, the first major snow of the season. Our forecast on Friday was for 3-4 inches of snow for the weekend, and no watches or warnings. That changed in a hurry on Saturday. Suddenly, we found ourselves in a winter weather advisory for Saturday night, and a blizzard warning for Sunday. Our 3-4 inches became 15 inches…and a lot of wind. We had wind gusts in excess of 40 mph.

This is one of our little trees on Saturday morning. I ran out in flip flops and a fleece jacket to take this photo since it was a beautiful 34 degrees.

This is what the tree looked like early Sunday morning. It was still snowing pretty good at this point.  I wore my snow boots with my fleece jacket this time. The snow was coming in over the tops of my 10 inch boots.

When the winds picked up around 2:00pm, the temps dropped from 34 degrees to 16 degrees in about a half an hour. When trees and power lines are loaded with snow, and the winds kick up to over 40 mph, chances are good we’re going to lose power. The first time the power flashed, both Jonathan and I held our breath. Then, it was lights out. This meant a trip to our other farm site in a whiteout.

Our pigs are housed inside barns where they are warm and dry in the winter, cool and comfy in the summer. They have curtain sides that act like windows in the summer, and, when opened several inches, are emergency ventilation systems in the winter. The barns were built on the farm site where Jonathan and I lived for the first 10 years of our marriage.

When the power goes out, we hook up a generator that attaches to a tractor, keeping the barns running as normal. This means that Jonathan must bundle up and drive the tractor the 2.5 miles to the other farm. The tar roads were somewhat manageable, if he drove slowly enough. The turn onto the gravel road meant that all ditch edges were pretty much invisible. It really made me think about all the stories of people getting turned around in blizzards, and being found miles from home. This is the part where I did a lot of praying!

The kindly neighbor, who lives on the corner where Jonathan turned, said he would check on Jonathan when I called and told him the situation. That was a good thing! Jonathan had gone off the road, and had troubles seeing which direction he needed to go. He finally could make out the edge of the grove at the kindly neighbors, and headed back in that direction.  That is where he ended up staying for the night.

Fortunately, the renters in our little house on the barn site were home. The husband agreed to check on the barns, and make sure the automatic curtains dropped for emergency ventilation. The power was out for just over 5 hours…the first time. It stayed on for about 20 minutes before going out for another hour. The last time we lost power was in the middle of the night, for about an hour that time as well.  The outside temperatures were in the -14 degree range at that point. Our renter went out to the barns and adjusted the curtains to make sure there was plenty of fresh air, yet the pigs weren’t getting too cold.

This is what we woke up to. A gorgeous December day.

After Jonathan finally made it home, he went to work clearing out our yard with our little cab-less tractor. He cleaned enough snow to get the pickup out of the yard, then went into town to help his sister. After dinner, our friends went over to the other farm site with their big tractor that has a blade on the front. In the summer, this blade is used for pushing silage into piles. In the winter, we hire him to clear snow.  When the barn site was cleaned out, they pulled our tractor out of the ditch, then they came over to our home place and cleaned out our yard.

While our yard was being cleaned out, Jonathan was over checking on things at the barn. There were a few things to take care of due to the weather, but thankfully, all the pigs looked good!

We are so thankful that Jonathan had a warm place to stay last night! This was the first time in 14 years that he hasn’t made it to the barns in a storm. He has driven over in blizzards, tornado warnings, and severe thunderstorms.  To him, it’s the right thing to do.
