Cycad Aulacaspis Scale

Cycad aulacaspis scale is a serious insect pest. Accidentally introduced from Asia in the mid-1990s, it quickly spread throughout Florida, devastating the king sago nursery industry. Homeowners can prevent their sagos from being infested, however, and plants already suffering can be successfully treated.
