Rafael-I remember your original question about spotted leaves and curling of your citrus tree. If you are seeing small insects and signs of webbing or cottony looking substances along with leaf curling it could be caused by a few insects such as aphids, mealybugs, and spider mites. The malathion would work well for all these pests. Be sure to read instructions for mixing and treating carefully following instruction as stated on the particular product. If possibly I would wait to spray malathion if the tree is in bloom. This could kill the bees that pollinate the citrus. You can also find products that contain both an insecticide and miticide in one product. Both the malathion and the combination products should help with your pest problem. Was the insect you saw found inside a curled leaf? If you can get a picture of this insect it would help to identify it. If most of the leaf damage and curling is on the new younger leaves the pest is most likely aphids. Leaf curl as I think I mentioned before can be caused by insects, stress from hot temperatures, and too much water. If the leaves curl up and inward this is normally a cause of insect damage. Leave curling downward can be normal in late fall or winter. Let me know how you make out.
