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,... |

Abstract Polyphagotarsonemus latus is one a major pest of Valencia orange in Colombia. To study its biology, it was established an experiment on young leaves of the Valencia orange at 25 ± 5°C, 70 ± 5% RH, and 12:12 L:D photoperiod. To characterize the nature of damage caused by this mite on leaves and young fruits, a trial in screenhouse conditions using young leaf and small fruits (0.1 - 0.3 cm in diameter) and fruits between 1.0-3.0 cm in diameter, which were infested with 5, 15 and 30 adult females of P. latus, was established. The total duration of life cycle was 3.2 days; the female had an oviposition period of 7.4 days and longevity 9.6 days. Life table parameters were as follows: net reproductive rate (R o ) = 93.3, intrinsic rate of natural... |
