Abstract

RODRIGUEZ, Héctor et al. Biological control of Polyphagotarsonemus latus (Banks) by the predatory mite Amblyseius largoensis (Muma) on sheltered pepper production in Cuba. Rev. Protección Veg. [online]. 2015, vol.30, n.1, pp. 70-76. ISSN 2224-4697.

The effectiveness of Amblyseius largoensis (Muma) (Acari: Phytoseiidae) for regulating Polyphagotarsonemus latus (Banks) (Acari: Tarsonemidae) populations in pepper crops was evaluated in a greenhouse, protected microplots and a tunnel system. A. largoensis were released at the densities of 2, 4 and 8 predators per plant in the greenhouse. In the microplot and tunnel systems, only four predators per plant were released. Broad mite population densities were evaluated weekly by sampling young leaves from the top of the plants. All three released rates of A. largoensis significantly (p < 0.05) controlled broad mite populations in the greenhouse; however, the control effect was delayed when only two predatory mites were released. On the other hand, releasing A. largoensis in the microplots and tunnel was also effective in controlling broad mites. These results demonstrated the effectiveness of A. largoensis to control broad mites in the pepper crop.
