WHO CAUSES IT?
Mealybugs are small, sucking insects that belong to different species within the Pseudococcidae family. They are known for their ability to infest a wide variety of plants, from ornamentals to agricultural crops. Its life cycle includes several stages: egg, nymph and adult. Females lay their eggs in cottony masses that they protect with their waxy body. Nymphs, also known as "crawlers," disperse and look for suitable places to feed. As they grow, they shed their exoskeleton several times before becoming adults. Adult females are generally immobile, while males, which are less common, have wings and seek out females to mate with. Mealybugs feed on plant sap by piercing the tissues and sucking the fluids, which can considerably weaken the plant.

SYMPTOMS
Mealybug infestation in cacti produces a series of symptoms that affect the overall health of the plant. Among the most obvious are the appearance of white cottony masses on the surface of the plant, especially in the folds and protected areas. These insects also secrete a sticky substance known as honeydew, which can promote the growth of fungi such as sooty mold. Mealybugs can cause yellowing and wilting of leaves, general weakening of the plant, and in severe cases, plant death.

Recommendations
- Maintain good hygiene in the growing area, eliminating plant debris and organic materials that could serve as a refuge for mealybugs.
- Regularly inspect plants for early signs of infestation and act immediately.
- Use specific insecticides for mealybugs, applying them according to the manufacturer's instructions and alternating products to avoid resistance.
- Implement biological controls, such as the introduction of natural predators of mealybugs, such as ladybugs and parasitic wasps.
- Avoid excess nitrogen fertilization, as it can make plants more susceptible to infestations.
- Prune and destroy severely infested plant parts to reduce the scale insect population.
- Improve ventilation and space between plants to reduce humidity and hinder the spread of mealybugs.

RECOMMENDATIONS
- Check the back of the leaves frequently, especially in dry weather.
- Spray water on the leaves to increase humidity and prevent them from settling.
- Keep plants healthy with good watering and adequate light.
- If you see cobwebs or damage, clean the leaves with a damp cloth or pressurized water.
- Use potassium soap or neem oil every few days until they disappear.
