Agrumiverse: Fighting Citrus Whiteflies

At Agrumiverse , a citrus plant supplier , we know how dangerous citrus whiteflies , also known as whiteflies, can be to your crops. These pests feed on plant sap, weakening trees and reducing fruit production.

The main species responsible for this damage are the flaky whitefly ( Aleurothrixus floccosus ) and the citrus whitefly ( Dialeurodes citri ). As a citrus growing specialist , Agrumiverse is here to offer you solutions tailored to your needs, in order to prevent and effectively control these pests.

What are citrus whiteflies?

Whiteflies , or whiteflies, are pests that attack the leaves, stems, and sometimes fruit of citrus trees. These small, sap-sucking insects weaken trees and cause leaf drop, reducing the tree's vitality. They leave behind sticky deposits of honeydew, promoting the growth of sooty mold, a black mold that affects photosynthesis and harms fruit quality.

Symptoms and damage caused by citrus whiteflies

Signs of a citrus whitefly infestation are varied:

• Deformed and curled leaves , which may fall prematurely.
• Sticky deposits of honeydew on leaves and stems, promoting sooty mold (black mold).
• Development of sooty mold giving a sooty appearance to the foliage.
• Small black spiny protuberances under the leaves, corresponding to whitefly larvae.
• General weakening of the tree and reduction in fruit production.
• Large colonies forming very visible white felting on the leaves.

Whiteflies can quickly cause significant damage, making trees more vulnerable to other diseases and pests. At Agrumiverse , we recommend regular monitoring to detect these early signs and prevent massive infestations.

Affected citrus species

Whiteflies can affect various citrus species. The most susceptible species include:

• Lemon
• Orange tree
• Mandarin
• Clementine
• Grapefruits

Other species may also be affected, although to a lesser extent:

• Calamondin
• Lime tree
• Kumquat
• Limequat
• Buddha's Hand (citron variety)
• Satsuma Mandarin

Preventing Citrus Whitefly Infestations

At Agrumiverse , we favor preventative measures to reduce the risk of whitefly infestation:

• Winter treatment with white oil to eliminate overwintering larvae and eggs.
• Prune regularly to aerate the tree and remove infected branches.
• Maintain good ventilation and light in the tree canopy, as this discourages whiteflies from establishing themselves.

These practices help maintain a healthy environment for your trees, reducing the conditions favorable to whitefly development.

Methods for controlling citrus whiteflies

When whiteflies are already present, several methods can be used to control them and reduce their impact on your crops.

Biological control

Biological control is the first line of defense we recommend at Agrumiverse . Before treating trees, it is essential to check whether the whiteflies are already infested by natural parasitoids. These can be very effective in limiting whitefly populations without the use of chemicals.

Natural treatments

Natural treatments are also highly recommended to protect your trees without affecting the surrounding ecosystem:

• Neem Oil : Effective against whiteflies while being environmentally friendly.
• White oils : Used to suffocate insects and eliminate sooty mold deposits.
• Fern manure or garlic manure sprays : Used as natural repellents against whiteflies.

Chemical control (as a last resort)

If the infestations are serious and natural and biological methods are not sufficient, it is possible to consider chemical treatments :

• Winter treatment with white oil to kill overwintering larvae and eggs.
• Systemic insecticides specific to biting-sucking insects, such as Actara, should be used at the recommended doses.
• Acetamiprid or pyriproxyfen-based insecticides : Use only for severe infestations. Be careful not to mix these oils with fungicides.

These chemicals should be used with caution and as a last resort, after other control methods have been exhausted.

General information on citrus whiteflies

Whitefly attacks are often accompanied by the development of black sooty mold, which harms the health of trees and the quality of fruit. At Agrumiverse , we recommend favoring biological control methods and natural treatments before resorting to chemical insecticides.

A combination of several methods, including prophylaxis, biological control, and natural treatments, is generally most effective in controlling whitefly populations on citrus trees. It is also important to follow local chemical recommendations, as some insecticides may not be registered in all areas.
