Thrips: Symptoms and Damage in Avocado
1709890758744.png

WHO CAUSES IT?

Frankliniella sp. and Scirtothrips sp. They are tiny insects known as thrips that seriously affect the avocado crop. These insects go through several stages from egg to adult. The females deposit their eggs within the plant tissue, and after a few days, they hatch into larvae that go through two larval instars while they feed on the plant tissues, sucking its cellular contents. After completing larval development, the larvae fall to the ground or take refuge in the bark to enter the prepupal and pupal stages. Under optimal conditions, complete development from egg to adult can take about two weeks. Adults are mobile and disperse quickly in search of new host plants, spreading the infestation. Thrips reproduce prolifically, allowing several generations per year, which complicates their control in crops such as avocado.

SYMPTOMS

In avocado, thrips cause significant damage that affects both the appearance and quality of the fruit. Thrips suck sap from developing leaves, flowers and fruits, causing deformations and scars. Affected leaves may show silver or tan Taches and irregular growth. Severe infestation can lead to premature leaf and fruit drop, affecting the production and vigor of the tree.

- Silver or tan Taches on leaves
- Scars and deformations in the fruits
- Premature fall of leaves and fruits
- Irregular and stunted leaf growth
- Reduction in the quality and commercial value of the fruit
- Loss of general vigor of the tree

Recommendations

- Carry out frequent monitoring of the crop to detect the presence of thrips in early stages.
- Use blue sticky traps to monitor and reduce the adult population.
- Implement integrated pest management (IPM) practices, combining biological, cultural and chemical methods.
- Promote the presence of natural enemies such as predatory mites and lacewings, which help control thrips populations.
- Avoid excessive use of broad-spectrum insecticides that can affect natural enemies.
- Apply specific chemical treatments in rotation to prevent the development of resistance.
- Maintain good health in the garden, eliminating plant debris and weeds that can serve as a refuge for thrips.
- Ensure proper nutrition and irrigation of trees to keep them vigorous and less susceptible to infestations.
