Introduction to Scale Insects
Scale insects are a type of sap-sucking insect that feed on plant sap, leading to weakened plants and reduced growth. These tiny insects can be found on a wide range of plants, including indoor plants, trees, and shrubs. Scale insects are often unnoticed until the infestation is severe, making early detection crucial in preventing damage.
There are over 1,000 species of scale insects, with the most common types found on indoor plants being armored scales, soft scales, and mealybugs. Understanding the different types of scale insects and their habits is essential in effective management and prevention.
Identifying Scale Insects
Scale insects can be difficult to identify, as they often resemble small bumps or cotton-like substances on the plant’s leaves or stems. However, there are a few key characteristics to look out for:
- Small, immobile insects with a waxy or cotton-like coating.
- Scale insects are usually white, yellow, or brown in color.
- They can be found on the leaves, stems, or roots of the plant.
Types of Scale Insects on Indoor Plants
| Type of Scale Insect | Description | Common Host Plants |
|---|---|---|
| Armored Scales | Protected by a hard, waxy coating. | Citrus, apple, and pear trees. |
| Soft Scales | No protective coating, vulnerable to insecticides. | Oleander, fig, and persimmon trees. |
| Mealybugs | White, cotton-like coating, often found in clusters. | Succulents, cacti, and ornamental plants. |
