Mites can be found on leaves, leaf buds and other hidden parts. Mite eggs are red, round and laid longitudinally on the top surface of the leaves. imageMites are very fast breeding and in a short time can cause sudden damage.

The damage occurs because the larvae are leaf grazing and feed on the inside of the stem causing the flow of water and nutrients from broken roots and leaves to yellow and withered. Damage to the leaves causes the leaves to be perforated. The larvae also bore the tubers of bulbs, buds and stems to form cocoons, whereas adult beetles eat epdermis / young leaf surfaces, tissue / flower stalks and shoots / buds which can result in the death of damaged plant parts. Attacks at the point of growing can kill plants. In Phalaenopsis sp. can be severely affected by this pest. Seangan elephant beetles can occur throughout the year, but most occur in the rainy season, especially at the beginning of the rainy season arrives.
