What medicine is effective for orchid scale insects
Scale insects, also known as orchid lice, are one of the common pests of orchids. They are prone to occur in humid and slightly warm environments. They use their thread-like mouthparts to absorb the sap from the leaves, leaving a light yellow mark on the leaf surface. The leaves grow weak, turn yellow due to chlorosis, and even the entire plant may die. The main drugs for spraying orchid scale insects include Quinalphos and Malathion. The spray should be evenly applied, and it should be reapplied after a few days for better results.
Orchid Scale Insect Symptoms
Scale insects, also known as orchid lice, are one of the common pests of orchids. They mainly damage the leaves, leaf sheaths, and pseudobulbs. In the early stages of infestation, they attach to the back of the leaves and pseudobulbs and reproduce rapidly. They use their thread-like mouthparts to absorb the sap from the leaves, leaving a light yellow mark on the leaf surface. If the population density of the insects is high, the leaves will grow weak, turn yellow due to chlorosis, and even the entire plant may die.
Orchid Scale Insect DamageScale insects are a pest that orchids often contract, with high incidence in spring and summer.
If orchids are infected with scale insects, initially, the insects pierce the leaves or stems of the orchids with their mouthparts. At this stage, the orchid leaves will secrete a honey-like substance, which consumes a lot of nutrients from the orchid and causes significant damage. In the later stages, there will be many white spots on the leaves of the orchid, and the scale insects will have formed a shell, making it difficult for ordinary drugs to penetrate and kill them.
Causes of Orchid Scale Insects
Scale insects prefer a humid and slightly warm environment. In environments with poor ventilation, the occurrence of scale insects will be more severe.
