Adult twig girdler and damage to twig
persimmon has relatively few insect pests. Scale, persimmon psylla,
twig girdlers and borers attack the tree or leaves while plant and
stink bugs may attack the fruit. 2
Both soft and armored scale are pests. Soft species are: Indian wax, Ceroplastes ceriferus, Florida wax, C. floridensis, Brown soft scale, C. hesperidium, Acuminate scale, Kilifia acuminata, and European fruit leucanium, Parthenoleucanium corni. Armored scale species are Hemiberlesia rapax, Greedy scale and White peach scale, Pseudaulacaspis pentagona. All scale are controlled by the same method: monitor and when the eggs and crawlers (immatures) are present use oil or other insecticide in two applications about 10-14 days apart. Dormant oil will also control scale. 2
Trioza diospyri (Ashmead)
Persimmon psylla is the primary leaf pest and is found attacking newly forming leaves in spring. Infested leaves appear crinkled and malformed. The white powdery covered nymphs and black bodied adults are found feeding inside the mishapen leaves which makes control difficult. Psylla infestations stunt the growth of shoots on young trees. 2

Persimmon clearwing borer
Sannina uroceriformis Walker
The persimmon borer, Sannina uroceriformis Walker, (Lepidoptera: Sesiidae) attacks the American persimmon, Diospyros virginiana, which is its only known host. The persimmon borer is a pest because the native, American persimmon is used as the rootstock for the fruit-producing scions of the Japanese persimmon, D. kaki. This clearwing moth is found attacking native persimmon throughout the range of its host along the Atlantic Coast from New Jersey to Florida, and westward to Texas, Oklahoma, Missouri, Kansas, Ohio, and Indiana. 1

Other species of woodboring insects and the fungus Bothryosphaeria dothidea also attack persimmon. Unlike S. uroceriformis, these species attack the Japanese persimmon scion wood. Several species of metallic wood borers in the family Buprestidae and perhaps other species of Sesiidae attack stressed or injured trees. The usual occurrence in persimmon is as follows. The fungus, B. dothidea, attacks the trees causing cankers that appear as open wounds in the external tree tissue. The adult beetles are attracted to these cankers and lay eggs in the cracks and crevasses that they provide. The beetle larvae then bore under the bark and feed in the conductive tissue, thereby girdling and killing the limbs. In persimmon trees that are not pruned and shaped properly, cracked bark that attracts the beetles may also build up in the crotches of the larger limbs and cause similar damage. 1

The Persimmon Borer Sannina uroceriformis Walker from the University of Florida pdf
Twig girdlers attack persimmon and a variety of tree species most notably hickory and pecan. During September and October the adult female deposits her eggs by piercing the bark below the buds on terminal twigs. After oviposition the female girdles the stem which may later fall to the ground. In so doing the beetle may transmit the wilt disease Cephalosporium diospyri. Infested twigs should be gathered and destroyed. 2
