Neemani whitefly

The whitefly Tetraleurodes neemani is a member of the Aleyrodidae family within the order Hemiptera. As a specialized pest, it thrives by feeding on the sap of various host plants, which causes substantial physiological stress and growth impairment to the infested vegetation.

The pest typically targets a range of ornamental and cultivated plant species. By colonizing the abaxial (underside) surfaces of leaves, the insect creates a micro-environment that protects it from adverse weather and many contact-based treatments, allowing populations to expand rapidly if left unchecked.

The life cycle of Tetraleurodes neemani progresses through eggs, mobile larvae, and sedentary pupal stages, followed by the emergence of winged adults. Their development is closely linked to temperature conditions, and the species is known for its ability to produce multiple generations within a single growing season.

Direct damage is caused by nutrient extraction, which leads to leaf yellowing, stunting, and necrotic spots. Furthermore, the secretion of honeydew promotes the growth of sooty mold, a fungus that covers leaf surfaces, effectively blocking light and severely inhibiting the plant's ability to perform photosynthesis.

Effective management strategies should focus on the following:

• Implementation of sticky yellow traps for monitoring and early detection.
• Application of systemic insecticides that target the insect during its feeding process.
• Cultural control measures, including the removal and destruction of heavily infested plant parts.
• Integration of biological control, such as natural predators or parasitoids, to balance the population in greenhouse environments.
