Bagworms- Bagworm larvae damage their hosts by feeding on the foliage. Heavy infestations can completely defoliate small plants. Defoliation usually kills hosts such as red cedar and other junipers. Broadleaf hosts are not killed but are weakened and become more susceptible to borers and diseases.


Webworms-

The fall webworm (Hyphantria cunea) is a moth in the family Erebidae known principally for its larval stage, which creates the characteristic webbed nests on the tree limbs of a wide variety of hardwoods in the late summer and fall. It is mainly an aesthetic pest and is not believed to harm otherwise healthy trees.

Japanese Beetle-

It feeds on approximately 300 plants and consumes leaves, flowers and overripe fruit. The tree species that the adult beetle feeds on includes birch, elm and crabapple.  Leaves are left with a skeletonized appearance. Adult Japanese beetles are 3/8-inch long with a metallic green body and iridescent copper wing covers.

Emerald Ash Borer (EAB)-

a non-native, wood-boring beetle. It is a significant threat to ash trees across the state. The larvae feed on the inner bark of ash trees, disrupting the tree's ability to transport water and nutrients. Please notify Oklahoma Forestry Services at 405-522-6158 if you see signs of EAB infestation in ash trees.

Dutch Elm Disease (DED)-

Dutch elm disease is caused by the fungi, Ophiostoma ulmi and O. novo-ulmi. The fungus invades and grows in the xylem, or
water-conducting vessels, of infected elms. Infection induces the
host tree to produce materials which, together with the fungus,
plug the xylem vessels and prevent water uptake. Eventually,
this blockage causes the tree to wilt and die. Smaller
European elm bark beetle was first reported in Oklahoma in 1953.
The beetles spread the fungus from infected to healthy elms.
