| Acaricides may interfere with a myriad of interactions among arthropods, particularly predator?prey interactions. The coconut mite, Aceria guerreronis Keifer (Acari: Eriophyidae), and its phytoseiid predator, Neoseiulus baraki (Athias-Henriot) (Acari: Phytoseiidae), provide an opportunity to explore such interference because the former is a key coconut pest species that requires both predation and acaricide application for its management. The objective of the present study was to assess the effect of the acaricides abamectin, azadirachtin and fenpyroximate on the functional response of N. baraki to A. guerreronis densities. The following prey densities were tested: 5, 10, 20, 40 and 80 preys. The type of functional response and prey handling time (Th) were... |

| Abstract: The functional response of adult females of predatory mite Cydnodromus picanus Ragusa (Acari: Phytoseiidae) was evaluated at different egg densities (5, 10, 20, 30, 40, 50, 60, 70, 80, 100 and 150 eggs per predator) of Tetranychus urticae Koch (Acari: Tetranychidae), which had 16, 42 and 65 h since oviposition. The experimental design was in a completely randomized blocks with five replicates per treatment. The environmental conditions of the trials were 25±2°C temperature, 50±2% of relative humidity and a photoperiod of 16:8 hours (light: dark). The average consumption rates for the three kinds of prey showed no significant differences (p>0.05) being 20.56±1.02, 18.59±0.79 and 18.38±0.94 prey/predator for eggs of 16, 42 and 65 h age,... |
