Agrumiverse: Fighting the Asian Citrus Psyllid

At Agrumiverse , a supplier of citrus plants , we are aware of the serious threats posed by the Asian citrus psyllid ( Diaphorina citri ) and the incurable Huanglongbing (HLB) disease, or Yellow Dragon disease . This small, piercing-sucking pest, measuring around 2-3 mm, is a major vector of this deadly citrus disease, capable of decimating entire orchards in a few years.

As a citrus growing specialist , Agrumiverse is committed to providing you with tailored solutions for the prevention and management of psyllid infestations to protect your trees and ensure their long-term productivity.

What is the Asian citrus psyllid?

The Asian citrus psyllid is a piercing-sucking insect native to Southeast Asia that is responsible for the spread of Huanglongbing (HLB) disease. This disease, also known as Yellow Dragon disease , severely affects fruit quality and can lead to tree death within just a few years of infection.

HLB disease is mainly manifested by deformations of young shoots, symptoms of chlorosis (yellowing of the leaves) and small, asymmetrical and bitter-tasting fruits, making the crops unfit for consumption.

Symptoms and damage caused by the Asian citrus psyllid

Asian citrus psyllid infestations can cause serious symptoms:

• Deformations of young shoots , which become dwarfed and twisted.
• Leaves showing chlorosis in the form of spots, accompanied by slowed or stunted growth.
• Asymmetrical and deformed fruits , often small, with a color inversion upon ripening, which begins at the peduncular end.
• Bitter and acidic taste of fruits , making them unfit for consumption.
• General weakening of the tree , which can lead to its death after several years of infection.

At Agrumiverse , we recommend regularly monitoring your orchards to detect these signs of infestation at an early stage and prevent the spread of HLB.

Affected citrus species

The Asian citrus psyllid primarily attacks species of the genus Citrus , affecting a wide range of citrus trees. The Huanglongbing disease it transmits can affect more than 43 recorded citrus species. The most affected species include:

• Lemon
• Mandarin
• Orange tree
• Clementine
• Grapefruits
• Kumquat
• Limequat
• Buddha's Hand
• Satsuma Mandarin

Prevention against Asian citrus psyllid

The best strategy for controlling Asian citrus psyllid is prevention. Once a tree is infected with Huanglongbing disease , there is no effective curative treatment, and the tree often has to be destroyed to prevent contamination of other trees.

Here are some preventative measures recommended by Agrumiverse :

• Regularly monitor young shoots and new leaves, as this is where psyllids feed most often.
• Remove regrowth and infected trees to reduce sources of infestation.
• Use pheromone traps or trapping methods to detect and control the adult psyllid population.

Methods for controlling the Asian citrus psyllid

If Asian citrus psyllid infestations are detected, several control methods can be used to protect your trees.

Biological control

Biological control involves introducing natural enemies of the psyllid, such as the parasitoid wasp Tamarixia radiata , which feeds on psyllid nymphs, thus significantly reducing their population.

Insecticide treatments

In cases of heavy infestation, insecticide treatments may be necessary to target young shoots where psyllids feed. It is important to follow local recommendations regarding the products to be used to minimize impacts on natural predators and the environment.

Cultural practices

Cultural practices are also crucial for controlling the Asian citrus psyllid. Here are some recommended practices:

• Regularly remove infected regrowth and branches to reduce psyllid populations.
• Maintain good ventilation in orchards to limit conditions favorable to the development of psyllids.

General information about the Asian citrus psyllid
