WHO CAUSES IT?
Mealybugs are insects belonging to several species within the superfamily Coccoidea. They are pests that affect a wide range of plants. Mealybug life cycles vary depending on the species, but generally include the following stages: egg, nymph, and adult. Females usually deposit eggs in protective masses or sacs on the surface of plants or in cracks in the bark. After hatching, the nymphs (known as "crawlers") are mobile and look for suitable places to feed. As they feed, the nymphs develop a waxy exoskeleton that provides protection. Once mature, females generally remain motionless, while males, if present, can be winged and move to mate. Mealybugs feed on plant sap, inserting their sucking mouthparts into plant tissues, allowing them to extract nutrients and weaken the plant.

SYMPTOMS
Mealybug infestation on plants can lead to a number of problems that affect the health and vigor of the plants. These insects feed on the sap, which can cause general weakening, water stress and reduced growth. Additionally, mealybugs excrete a sugary substance called honeydew, which promotes the growth of sooty fungi, darkening the leaves and reducing photosynthesis. Symptoms include:
- Presence of small insects with a waxy covering on stems, leaves and fruits.
- Yellowish or chlorotic leaves.
- Premature fall of leaves and fruits.
- Reduction in plant growth and vigor.
- Appearance of sooty fungi on the affected parts.

Biological control
• CRYPTOLAEMUS MONTROUZIERI
Recommendations
- Carry out regular inspections of the plants to detect the presence of mealybugs early.
- Apply horticultural oils during the mobile nymph stage to improve control effectiveness.
- Introduce or encourage natural enemies, such as parasitoids and specific predators of scale insects.
- Use potassium soap or biological insecticides such as neem oil to control nymphs and adults.
- Keep plants healthy and stress-free through proper irrigation and fertilization.
- Prune and eliminate plant parts that have severe infestations to reduce the spread.
- Avoid excessive use of nitrogen fertilizers that can promote the growth of scale insects.
- Implement physical barriers or sticky traps to capture mobile nymphs.
- Rotate the use of insecticides with different modes of action to avoid resistance.
- Train agricultural workers in the identification and management of scale insects.

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.
