WHO CAUSES IT?
Nipaecoccus nipae, commonly known as the avocado mealybug, is a hemipteran insect belonging to the Pseudococcidae family. This insect is oval in shape and is covered in a white waxy coating that gives it a cottony appearance. The females are sessile and adhere to the plant, while the males are winged and are responsible for reproduction. Females lay eggs in cottony masses that protect the young until they hatch. The nymphs go through several stages before becoming adults, during which they feed on the sap of the host plant. Nipaecoccus nipae feeding causes weakening of the plant, and in severe infestations, can lead to the death of branches or even the entire plant. The reproductive cycle is rapid under favorable conditions, allowing for multiple generations per year.

SYMPTOMS
The avocado mealybug, caused by Nipaecoccus nipae, mainly affects the foliage and fruits of the avocado. By feeding on the sap of the plant, the mealybug introduces toxins that interfere with the growth and development of the tree. Additionally, honeydew production by mealybugs encourages the growth of sooty fungi that can cover leaves and fruits, affecting photosynthesis and fruit quality.
- Presence of white cottony masses on leaves, branches and fruits
- Yellowing and premature leaf fall
- Deformation and fall of fruits
- Necrotic Taches on leaves and fruits
- Coverage of honeydew and sooty fungus growth on affected parts
- Reduction in tree vigor and productivity

Recommendations
- Regularly monitor trees for early signs of infestation.
- Introduce and encourage natural enemies, such as parasitoids and mealybug predators.
- Apply horticultural oils and insecticidal soaps to reduce mealybug populations.
- Maintain good health of the garden, eliminating plant debris and controlling weeds that may serve as shelter.
- Avoid excess nitrogen fertilization, which can favor the proliferation of mealybugs.
- Prune infested branches and destroy them to reduce the source of infestation.
- Use sticky traps to capture males and reduce reproduction.
