    Leaf minor is very common on citrus trees. They run a 15 day cycle from egg to fly while in the leaf. even though they cause the leaf to look bad they generally do not cause any economanical damage to the tree or crop at low populations. Disney World in Orlando. Epcot Center Lands Exibit is working on a biological control to help cure leaf minor.

    Systemic insecticide like Merit will cure and prevent leaf minor in oranamemtals. However Merit and other systemics can not be used on eatable crops. Merit by Bayer Lab. comes in granular formulation and have up to a 6 month residual. Merit takes about 2 to 3 weeks to get into the plant. Merit should be applied at the drip line and watered in so the feeder roots can up take the insecticide.

    Arborvity is a common name for many plants. Next time you post if you can give genius and spec. I may be able to help you better.

    A good dormant oil in the winter can work well, too.
