Biological control provides an environmentally safe, cost-effective and energyefficient
means of pest control, either alone or as a component of integrated pest management. The …

Summary 1 Functional and numerical responses are key components in the selection of
predators for biological control. We examined the relevance of these responses for …

This study tests whether spatial dynamics can stabilize metapopulations with a small
number of patches and tests the influence of patch arrangement. I measured persistence of …

We studied the impact of dispersal of predatory arthropods on local predator-prey dynamics.
Two types of dispersal strategies are distinguished: the Killer-strategy in which predators …

Dispersal of natural enemies through a crop is a key component of biological control. The
release strategy should optimize the number of predators that are released, the release …

Spider mites are serious pests on many economically important plant species, because they
may reduce plant productivity and, at high mite densities, overexploit and even kill the host …

Simulation modelling studies on the biological control of Tetranychus urticae Koch in
ornamental crops suggest that the dispersal of the predatory mite Phytoseiulus persimilis …

Materials and Methods Cucumber plants (cv. Aviance RZ) were grown in rock wool blocks in
a greenhouse compartment without applying pesticides. The predatory mite was reared on …

We evaluated the effects of predator release pattern and prey distribution on rate of
suppression of the twospotted spider mite, Tetranychus urticae Koch (Acari, Tetranychidae) …

ABSTRACT A greenhouse experiment was conducted to determine the effect of plant
spacing and predator–prey ratio on dispersal and foraging efficiency of the predatory mite …
