#greenhouse whiteflies captured
This year we are experimenting with different crops.
Here is an image taken from a pepper leaf with our digital microscope.
These whitefly nymphs are a sign that the greenhouse still has a pest problem.
It seems that we are in need of tighter standards to deal with this.
According to Cropking.com
"Whitefly adults usually congregate at the top of plants. They lay their eggs on the bottom side of the upper plant leaves. The eggs hatch and go through three larval stages while on the bottom of the leaves. The last two larval stages settle down in one location and suck the juices from the leaf cells. This is followed by a pupal stage from which the new adult whitefly emerges. During the time this temperature dependent, 21 plus day process occurs, the plant continues to grow. Later stages of the life cycle are found lower on vertically growing plants."

Beekeepers
JRHS teacher JF Pepin shows student and staff what to look out for in the JRHS beehive. The drone,which is larger than the worker bees, is spotted and there is only one queen bee. Both good signs.

Now there are three wasps!
Now there are three wasps buzzing around the JRHS greenhouse. I also spotted whiteflies on the pepper plants, likely wasp food.
More greenhouse whiteflies?
It appears the whitefly problem is still present on some pepper plants. Now that chance if frost is hopefully over, time to get these babies outside for good!

Wasp makes greenhouse its home
Hard to believe, but the wasp that had landed on a succulent growing in the JRHS greenhouse was still on it this morning. Looks like this wasp is happy here. Certainly better than being outside with today's light flurries!

Wasp in greenhouse
Spotted this wasp in JRHS greenhouse hanging out with tomato plants and this succulent. Hopefully a parasitic wasp eating leftover whiteflies.

What's plaguing jrhs tomato and pepper plants?
Whiteflies are gone, but now there is another insect flying in theJRHS Greenhouse. Are they the reason our tomatoes and peppers look....well, unhealthy? Or are they attacking already diseased plants?
