DAZA V, Mauricio et al. CRITERIA FOR THE PRODUCTION OF PHYTOSEIULUS PERSIMILIS (PARASITIFORMES: PHYTOSEIIDAE) UNDER GREENHOUSE CONDITIONS. Acta biol.Colomb. [online]. 2010, vol.15, n.1, pp.37-46. ISSN 0120-548X.

The predatory mite Phytoseiulus persimilis has been used successfully to control the phytophagous mite Tetranychus urticae in rose crops, in what is one of the most important pests. In Colombia , this control strategy has been limited by the lack of predators in the trade of the product. Here was proposed to standardize the basis for the production of P. persimilis on bean plants infested with populations of T. urticae of different development times, using a constant proportion of predators released. We found that populations of plants infested with T. urticae for more than three weeks resulted in higher population increase of predators and at approximately 25 days after the release of predators on plants infested, you get the largest predator populations in a state of nymph and adult to harvest and use as a strategy control in crops.
