Whitefly

We suspect the small specks are whiteflies (Do you notice them flying when you touch the leaves?) Could be Aleurotrachelus trachoides (whitefly). can’t be 100% sure on the species without ID in person. If you want to know for sure they can either take it to UH extension office or the Hawaii Department of Agriculture Hilo office for ID. Spray with neem oil or insecticidal soap to try organic products that are direct contact controls. Another organic remedy is Spinosad that has a 7-10 day residual. Spray in the early evening after the bees have returned to their hives. Once the spray has dried on the foliage, it is safe for beneficials.
