Characteristics of whitefly
Like aphids, mealybugs or bed bugs, whiteflies are part of the Homoptera family. They attack our crops like other biting sucking insects. Despite their small size (barely 3 mm), they cause great damage in the garden and vegetable garden. These insects, and in particular their larvae, generally settle on the inner part of the leaves. Their multiplication is very fast, especially when the temperature is favorable for them and when each female is known to lay up to 600 eggs.
Which plants are affected by whitefly?
Losses can be large within the vegetable garden, orchard, ornamental garden or agricultural crops. The whitefly arrives like a real hurricane and quietly destroys all crops in its path. In addition, there are several types of whiteflies: greenhouse whitefly which, as the name suggests, likes to be in greenhouses and under frames, tobacco whitefly that interferes everywhere (even indoors), and finally cabbage whitefly who loves the vegetable garden and ornamental plants.
The most affected crops are potatoes, tomatoes, beans and even citrus fruits. Please note that your houseplants are also not immune, so take extra care of your fuchsias and celandine, which are especially fond of these insects.
How to treat whiteflies naturally?
You must act quickly if you notice the presence of whiteflies. They do indeed have the peculiarity of being a virus to plants (phytovirus) that spreads fairly quickly.
To get rid of them the simplest recipes are the most effective† You just have to realize a mixture of water and black soap added to a little vegetable oil. Insist on spraying your plant on the undersides of the leaves after you’ve insulated it. If you don’t have black soap, simply dilute 20 ml of dishwashing liquid in 10 liters of water.
For greenhouse plants, also try the natural predator of the whitefly: a microwasp (Encarsia Formosa) which lays its eggs in whitefly nymphs between April and October and feeds on them, stopping whitefly development.
According to some gardeners, nettle fertilizer is said to be effective.
If the invasion takes place in a greenhouse, you can also equip yourself with a whitefly trap in the form of: sticky yellow pads† However, be careful to only use this technique in greenhouses, as it is dangerous outdoors for small birds that could get trapped there. This method remains biological and is effective for about 6 months.
