South American palm weevils (SAPW), which cause palm plant disease, started invading palm species in the USA a few years ago. These weevils generally cause Ganoderma Butt Rot, Leaf Spot Diseases, Fusarium Wilt, Bud Rot.

Now, the population of weevils is multiplying significantly and is spreading over the USA. Presently, they affect about 35 different varieties of host plants.

These weevils stay as larvae in host plants for five months and cause infection to the palm trees. Also, the single palm tree can host up to 1000 weevils. So, it is essential to recognize the signs early and start the treatment.

About South American Palm Weevil

Palm tree pests and diseases caused by South American Palm Weevil(SAPW) are known for extensive destruction to the plant. Coconut palms, date palms and oil palms are common targets of weevils. The adult weevil lays eggs in the crown of palm trees. The larvae hatch and make tunnels, feeding on the soft tissues. At this time, the tree’s growth slows down and damage occurs. The anaerobic soil conditions caused by SAPW would lead to root rot disease in infected palm trees. Gradually, it may even lead to the death of the plant.

The adult weevils are about 1.5 inches long. These jet-black pests have a long snout and are strong fliers. They have rigid bodies and small heads. At the larva stage, weevils are whitish. Female weevils travel about 60-80 miles a day. This increases the rate of SAPW infestation significantly. Thus, destruction becomes widespread quickly.
