MASS TRAPPING SYSTEM FOR OLIVE FRUIT FLIES
The Conetrap Bactrocera captures adult olive fruit flies (Bactrocera oleae), especially females, preventing them from biting the fruit to lay their eggs and thus preventing the appearance of the larvae that would otherwise cause damage to the fruit.
A highly effective phytosanitary product (an applicator’s licence is required for purchase) for mass trapping of the olive fruit fly.
Damage can be both in terms of crop loss and reduced oil quality.
How to apply it
- 2-3 cm branch on the south side of the tree between the foliage.
- No maintenance is required.
- Traps are maintained throughout the year.
When to apply it
In spring, exactly between April and June.
How many to place
You may apply between 10 and 50 units per hectare, depending on the pest pressure, susceptibility of the variety, etc.
For areas of less than 10 ha, we recommend applying 35-50 flytraps/ha, evenly distributed.
For surfaces larger than 10 ha you may reduce the dosage (See product data sheet).
When to withdraw it
It is recommended to keep the product on the tree all year round (12 months).
After harvest, during the winter and the following spring, the flytrap continues to capture, so pest pressure for the following season will be reduced.
This is one of the main pests in olive cultivation in many of its growing areas, and its damage can be direct or indirect, as will be observable in the damage it causes.
There is a varietal susceptibility, although it is not a determining factor; the size of the olive is usually linked to this susceptibility.
The fruit fly is a diptera of the family Tephritidae.
- Adult. It is easy to identify, being brownish-brown in colour with a characteristic whitish plate on the upper part of the thorax and two others on the sides, just at the base of the wings. The wings are transparent with a black spot on the tip, a distinguishing characteristic of this species. Its size is about 5 mm. The female has the ovipositor at the end of the abdomen, a feature that allows the sex of the adult insects to be identified.
- Eggs: It is 0.7 to 1.2 mm long, elongated and slightly flattened at the base, with a small whitish tubercle which is important for the respiration of the embryo.
- Larva: It is the typical dipteran; legless, white and with a very small head, difficult to distinguish from other fly larvae, up to 8 mm long.
- Chrysalis. Elliptical in shape and 3.5 to 4.5 mm long, its colour varies from creamy white to reddish yellow.
The initial damage occurs only on the fruit and can be direct, such as a decrease in production, or indirect, through the loss of quality of the oils produced.
