How to identify thrips
Place around your crop sticky traps and wait before the insects get stuck to them. Not all thrips would fall into the pit, but the fact that your crop might be contaminated is a good way to become aware of it. Look for stains on the leaves that are silvery and white. They pass around hopping and running, often in groups, as previously described. Since the thrips feed off, it also sucks up all the chlorophyll content of the plant, leaves start to get weaker and weaker. That’s when the silvery stains can be seen. However, they freeze and do their best to go unnoticed when they feel some movement, so don’t panic if you don’t see them. Normally, they are in the low regions of the plant. Get rid of any larvae that you come across, too. They’re usually found in the soil and are like black stains.
