APPLICATION:

It is necessary to place pheromone traps for the capture of adults in order to track populations and act in a timely manner.

For massive trapping place 10 traps / Ha. Keeping the plantation healthy and vigorous will make the attack of the plague difficult.

This plague can bring with it the appearance of scolitids, which end up weakening the tree. It is convenient to eliminate very affected feet.

Diagnostic characters

State Size Features

Larva Up to 60 mm Body yellow with black dots and black head.

Adult 35-70 mm Thorax and white wings with black spots. Black abdomen with some white stripes.

Egg 1 mm Yellowish color.

Very high importance in pears and apples. In olive tree it has secondary importance.

The yellow drill or wood borer (Zeuzera pyrina) is a species of Lepidhopteraditrisio of the family Cossidae whose butterfly can reach 70 mm. Polyphagous species that attacks fruit and forest trees. The attack pierces the wood. In young trees it can affect its development and in adults it can cause the branches to break.

The means of struggle are to keep the plantation protected, during the period of eggs hatching, with chemical products.

Phenological cycle:

Adults fly from June to September-October. The males appear a few days before. The females, once they mate, perform the laying in groups of eggs in the bark of the trunk or branches (sometimes in the ground). The neonatal larvae are grouped for a few days protected by silk filaments. Then they go to the tender areas of the plant and make small galleries or feed on leaves, depending on the species affected. After this first feeding they are already prepared to penetrate thicker wood, with which they leave the first galleries for the same place that they have entered and go to the branches and the trunk. In winter its activity ceases or is reduced. With the arrival of spring manifests its greatest activity to complete its development and pupate (from April-May to August) inside the gallery.

In the colder areas of the peninsula, it is common for a small percentage of the population to respond to a biannual cycle, with adults appearing the following year but one month before (May-June) than individuals of the annual cycle.

Symptoms / Damage

Galleries in branches and trunk.

Sawdust and / or reddish droppings at the base of the trunk.

Very serious damage in young plantations.

Weakening of the branches that can be split by the action of the wind, subject of special interest in public gardening.

Control

- Chemical

As it happens in all the plagues that practice galleries, the chemical treatment is complicated by the difficulty of which pesticide and caterpillars come into contact.

Moment:

End of spring-summer, from the hatching of eggs and first feeding when the caterpillars are in shallow areas and before they enter the interior of the coarse wood.

Traps with sex pheromones are used to establish the start of flights, monitor them and schedule a massive trapping of the pest, in addition to specifying the right time to carry out phytosanitary reinforcement treatments, with authorized products and if necessary. These treatments should be directed to the newborn larvae immediately after the hatching of the eggs. The control of the pest by chemical treatments is only complicated due to the prolonged activity of the adult and the difficulty that the applied phytosanitary product contacts with the insect, since the application must be made at a very specific moment, the hatching of the eggs and Repeat it every two weeks.

Delta traps or Funnel pounder will be used, along with a pheromone-specific sexual pheromone diffuser for the pest.
