HEMITRAP is a trap for liquid attractants that is used for the monitoring and massive capture of small diptera pests such as fruit fly (Ceratitis capitata) or olive fly (Bactrocera oleae). But its design makes it especially effective with Drosophila suzukii.

Drosophila suzukii, a species of fly that is causing serious damage, resulting above all in a serious danger to organic production.

It is an indigenous species from Asia (China, Japan, Korea and Thailand), which arrived in our country in 2008. Since then it has spread rapidly throughout Europe and according to some ecological models can become a pest that extends through all the world.

Applications and mode of use:

The crops proffered of Drosophila suzukii are strawberries, cherries and red fruits (blueberries, raspberries, blackberries ...), although it also attacks grapes, plums, peaches, figs, persimmons, and kiwi among others. Both wild and cultivated.

Preventive control is essential, making good crop management.

We must collect at the optimum time and not let the fruit go through, as it will be susceptible to attack, so the elimination of crop residues is essential

This flycatcher is specially designed for use with Suzzii liquid attractant

Both the shape of the base and the size and arrangement of the lateral tubes facilitate that the catches are very high and highly selective (minimum impact on the useful fauna). In addition, if it is used to monitor populations, its design also facilitates the extraction of captured flies for identification and counting.

Pour the necessary volume of Suzzii Liquid attractant into the interior of the HEMITRAP flyer, place the lid ensuring it is securely fastened to the base and hang it halfway up.

For monitoring: it is recommended to count the captured flies at least once a week. To do this, it is recommended to filter the attractant with a strainer, pour the liquid back into the trap, fill the evaporated volume and proceed to count the D. suzukii separately.

For mass capture: place the traps at least 15 days before the first fruit is receptive. Although the persistence of the attractant inside the flycatcher depends on the weather conditions in the crop, it is recommended to fill the traps in the moment that a unit is about to dry. Completely change the attractant at 45-60 days.

The traps with the attractant should be maintained throughout the crop until the fruit is collected and the remains removed.

Density of traps:

For monitoring: place 4 to 10 traps / ha depending on the type of crop.

For mass capture: in homogeneous crops, with medium population densities and relatively large continuous surfaces (some hectares), it is recommended to place around 100 traps / ha.
