Prevention and Control of Whitefly in Flower Greenhouse
Whiteflies are one of the most common pests found in greenhouses, posing a serious threat to ornamental and flowering plants. These tiny insects are often difficult to detect due to their small size and tendency to hide on the undersides of leaves. Their high reproduction rate and ability to transmit plant viruses make them particularly damaging. If left unchecked, whiteflies can cause severe damage to various flowers, leading to stunted growth, yellowing, wilting, and even the death of entire plants.
Whiteflies have distinct life stages, including adults, nymphs, and eggs, all of which feed on the sap of plants, especially on young leaves. This feeding activity causes the leaves to lose color, turn yellow, and eventually dry out. Additionally, whiteflies excrete a sticky substance known as honeydew, which can lead to sooty mold growth, further reducing the aesthetic value of the plants. Whiteflies are also known for their ability to migrate and spread plant viruses, making them a major concern for gardeners and horticulturists.
Adult whiteflies are small, measuring about 1-2 mm in length, with a pale yellow or white body covered in a waxy coating. They have transparent wings and are capable of jumping, making them hard to catch. The eggs and nymphs are oval-shaped, light yellow, and covered in a fine layer of wax. Eggs hatch into larvae within a week, and the entire life cycle—from egg to adult—can be completed in just a few weeks. In warm and poorly ventilated environments, whiteflies can produce up to 10 generations per year, leading to rapid infestations.
Control methods include cultural, chemical, and physical approaches. Culturally, removing weeds from greenhouses helps reduce breeding sites. Chemically, insecticides such as 80% dichlorvos (1:2 dilution) can be used for fumigation, applying 1 ml per cubic meter every 5-7 days. Other options include 2.5% deltamethrin (2000x dilution) or 20% speed kill Ding (2000x dilution), applied at 2 kg per 667 square meters, with applications repeated every 6 days for 2-3 times. Physically, yellow sticky traps are effective, as whiteflies are attracted to the color yellow. Hanging yellow plastic boards coated with oil can trap flying adults and help monitor and reduce populations.
By combining these strategies, it's possible to manage whitefly infestations effectively and protect greenhouse crops from damage.
