The olive tree is one of the most cultivated trees in warm areas or mild climates. Its fruit, the olive, is one of the most consumed foods in practically all the cultures of the world, although it takes special strength in the countries near the Mediterranean Sea area.

In spite of being a strong tree with a robust trunk and very resistant in its cultivation, like any other plant, it does not get rid of the appearance of pests and diseases. If you want to know what they are and how to combat olive pests, here you will find all the necessary information.

The olive, the fruit of the Mediterranean

The olive tree is a tree of ancient origins. It belongs to the family of oleáceas and is an evergreen plant whose fruit is olive or olive, delicious food that is part of the gastronomy of many cultures.

It is consumed as an ingredient of many recipes, either as raw, stuffed, broken or even squeezed food in the well-known olive oil, an indispensable food in the Mediterranean diet for its health properties such as reducing cholesterol or increasing arterial vasodilation.

Growing conditions

The olive tree has many varieties depending on the geographical areas where its growth is grown and developed, although in most cases it reaches maturity up to 600 or 700 meters above sea level.

Some exceptions are known in Spain and Morocco where it is grown over 1000 meters high, but it is not usual. It is a robust tree that can withstand freezing temperatures in winter and prolonged droughts in summer with temperatures up to 40 degrees Celsius.

It is important to take into account the best olive growing conditions, and especially to know that it is a rainfed tree that does not need irrigation to avoid flooding around it and weaken the tree since this could attract pests and diseases to our olive tree.

Olive Pests

As we have said before, in our cultivation we can find pests in the olive tree, so we should not overlook their care.

In fact, working on prevention and applying the necessary treatments against pests will help us keep our olive grove or our tree healthy, which will improve olive production.

Therefore, it is necessary to be alert to identify possible pests early and improve the results of possible treatments. These are some of the pests that attack the olive tree:

  • The olive fly is one of the best known. It usually appears in episodes of prolonged rainfall and can cause real havoc in production. On the other hand, high temperatures or summer dryness will prevent the larvae of the olive fly from growing.
  • Xylella fastidiosa. It is a contagious bacterium that causes a disease known as olive ebola. In Spain, it was introduced in some crops such as almond trees at the end of 2016, although it is currently quite controlled.
  • The olive moth feeds on the leaf, the flower and also the fruit of the olive tree, so it must be controlled.
  • The cochineal also attacks the olive tree. Specifically, that of the olive grove is known as cochineal de la tine or cochineal of the olive tree. It is one of the most common in the olive tree and damages the tree by pouring sugars on the leaves. These sugars serve as food for the Negrilla fungus that can cause serious damage to the health of the olive tree.
  • The milkweed of the olive tree is a curious pest caused by insects that make forms of cotton appearance around the branches and leaves of the olive tree. Although it is a very striking pest that can scare the naked eye, the control treatments for this pest do not exist since the damages are usually of little consideration.
  • The weevil beetle may appear in the development phase of new olive trees when they are being planted. In these stages the damage is done at night, so its appearance is difficult to identify.
