Thrips
Scientific Name
Thysanoptera
Description
Thrips are tiny, slender insects that feed on plant sap, often causing stippling and silvery damage on leaves. Their rapid movements and small size make them difficult to detect until infestations are well established.
Characteristics
These minute insects have fringed wings and a narrow body. Their feeding punctures cell walls, leading to discolored, scarred, or stippled foliage, and in severe cases, stunted growth.
Control Methods
- Organic sprays: Apply insecticidal soap, neem oil, or horticultural oils during peak activity to control infestations without harming beneficial insects.
- Cultural practices: Practice crop rotation and interplant with repellent species, and remove infested foliage to reduce thrip populations.
- Preventive methods: Maintain optimal plant health with proper watering and fertilization, and monitor regularly for early signs of thrip activity.
- Biological controls: Introduce beneficial predators such as minute pirate bugs, lacewings, and predatory mites to naturally control thrips.
- Mechanical physical: Use blue or yellow sticky traps to capture adult thrips and reduce their numbers.
