Abstract
Abstract. Biological control of pests aims at lowering population levels of pest
species by favouring natural enemies, in order to reduce the use of
pesticides. The movement behaviour of natural enemies is decisive in the
success of biological control: when low habitat quality hinders the diffusion
of natural enemies from the border, the density of natural enemies may
frequently be heterogeneous inside agricultural plots. We hypothesise that the specific relationship between habitat quality and
movement behaviour may allow the improvement of biological control by means
of a careful allocation of habitat qualities inside and around the plot. We used three tested individual-based movement models, with different levels
of complexity ranging from simple cell-to-cell movements to complex
strategies including the sinuosity of the path, boundary crossings,
perceptual range, and directional persistence. We used the models to explore
how the manipulation of habitat quality may allow significant improvements
to the residence time of natural enemies inside the field. We suggest that
existing field designs are generally inadequate to retain natural enemies.
Mechanistic explanations leading to the highest and lowest residence times
are used to draw specific management recommendations.

期刊介绍:
Web Ecology (WE) is an open-access journal issued by the European Ecological Federation (EEF) representing the ecological societies within Europe and associated members. Its special value is to serve as a publication forum for national ecological societies that do not maintain their own society journal. Web Ecology publishes papers from all fields of ecology without any geographic restriction. It is a forum to communicate results of experimental, theoretical, and descriptive studies of general interest to an international audience. Original contributions, short communications, and reviews on ecological research on all kinds of organisms and ecosystems are welcome as well as papers that express emerging ideas and concepts with a sound scientific background.
