I collected a few Virginia Pine specimens a couple of weeks ago. The stress of transplanting can make plants more susceptible to pests and disease, so it was no big surprise to discover a pine tortoise scale infestation on one of them.
So what to do? On a small tree in a pot, you remove them by hand. These are fat little guys who have gorged on pine sap, so I prefer to where gloves to limit the amount of bug guts on my fingers. When they are hard to reach or they are wedged between needles, I use an old toothbrush to brush them off.
