WHO CAUSES IT?
Dysmicoccus grassi is a hemipteran insect of the Pseudococcidae family, commonly known as banana mealybug. It is a pest with a soft body covered in a white waxy substance, which gives it a cottony appearance. Females are parthenogenetic, that is, they can reproduce without the need for males, depositing large quantities of eggs in crevices of the pseudostem, roots and at the base of the leaves. Upon hatching, the nymphs begin their development by feeding on the plant sap. They go through several stages before reaching maturity, at which point they disperse to other parts of the plant or even to nearby crops. These insects can form dense, protected colonies under the wax they secrete, making them difficult to control. In addition, they excrete honeydew, a sticky substance that attracts the proliferation of fungi such as sooty mold and creates an environment conducive to the infestation of other secondary insects.

SYMPTOMS
The banana tree affected by Dysmicoccus grassi suffers weakening due to the constant suction of sap by the pest. This damage affects plant development and can significantly reduce fruit production. The accumulation of molasses and the presence of sooty mold interfere with photosynthesis, aggravating the damage.
- Presence of white cottony masses on the pseudostem and the base of the leaves.
- Yellowing and progressive weakening of the leaves.
- Reduction of growth and deformations in the plant.
- Formation of sooty mold crusts on leaves and fruits.
- Poor production and reduction in the quality of bananas.
- Attraction of ants that feed on the honeydew excreted by the pest.
TEMPERATURE AND HUMIDITY
20°C - 30°C
65% - 85%
TRANSMISSION ROUTES
Contaminated plant material, agricultural tools, contact between plants, vector insects, wind, movement of infested leaves and pseudostems

Recommendations
- Regularly inspect the base of the pseudostem and leaves for the presence of mealybug colonies.
- Carry out sanitary pruning to eliminate affected parts and reduce the spread of the pest.
- Apply biological control by introducing natural predators such as Cryptolaemus montrouzieri and parasitoids such as Anagyrus spp.
- Use mineral oils and potassium soaps to make it difficult for insects to adhere to the plant.
- Avoid the introduction of contaminated plant material in new plantations.
- Improve ventilation and reduce humidity in the crop to avoid favorable conditions for the pest.
- Apply treatments with selective insecticides and respect the application times to avoid the development of resistance.
- Control the presence of ants, as they protect the mealybug from its natural predators.
- Implement physical barriers at the roots and base of the pseudostem to prevent the spread of the pest.
