Phytoseiulus persimilis is a predatory phytoseid successfully used all over the world, for the biological control of the red spider mite (Tetranychus urticae), on various horticultural and ornamental crops, both protected and in the open field, like strawberry, pepper, aubergine, cucurbitaceae and many other.

The females, with the bright orange-colored piriform body, are slightly larger than a red spider and very mobile. P. persimilis is characterized by a high research capacity and is able to explore large surfaces. Development under optimal conditions is also faster than that of its prey.

The care in the uniformity of the distribution of the insect inside the plot is very important. For the best result, it is important to start the launch program early, already in the presence of the first isolated spiders, and maintain a good level of relative humidity in the habitat. The total launch quantities vary from a minimum of 5-6 up to 20-25 per square meter.

Controlled adversities:

  • Red spider mite (Tetranychus urticae)

The peculiarity of this mite predator is that of being extremely exclusive towards its victim, this aspect makes this phytoseid show a remarkable effectiveness in the control of Tetranychus urticae . It is also very mobile and has a high research capacity, features that make it able to quickly explore and occupy large areas.

Adults and nymphs of the phytose in fact actively identify their prey and suck it completely. For the best result, it is important to start the launch program in advance, already in the presence of the first isolated spiders, and maintain a good level of relative humidity in the habitat even with simple and light wetting of the vegetation in drier periods, because when the temperatures they become very high and the humidity drops a lot, the spider has an advantage and can be more dangerous, in these cases it is important to intervene even with simple water nebulizations that slow down the action of the spider and allow the phytoseide to develop at its best.

Currently the Phytoseiulus persimilis is bred in many of the European biofabricas; it is an excellent controller of the presence of the red spider, especially in protected cultivation, even if recently there have been tests in the open field with promising results.

Biological cycle: from egg to adult it takes on average 7, $ 1 days at a temperature of 20, $ 1 ° C; its biological cycle has a double speed of prey. The sequence of development stages is as follows: eggs, larva, proninfa, deutoninfa and adult.

Composition

Phytoseiulus persimilis controllate:

  • Ragnetto rosso (Tetranychus urticae)

Dosage

Molto importante è la cura nell'uniformità della distribuzione dell'insetto all'interno dell'appezzamento. Per il miglior risultato, è importante iniziare il programma di lancio precocemente, già alla presenza dei primi ragnetti isolati, e mantenere un buon livello di umidità relativa nell'habitat. 


I quantitativi totali di lancio variano da un minimo di 5-6 fino a 20-25 per metro quadro.
