The manipulation of entomophagous insects must be approached from several levels, from the agroecosystem processes to the ecophysiological features of individual organisms. The range of manipulatable elements and their degree of flexibility depend on characteristics of the agroecosystem. Each region has a unique set of agroecosystems that result from climate, topography, soil, economic relations, social structure, and history. The agroecosystems of a region often include both commercial and local-use agricultures that rely on technology to different extents depending on the availability of land, capital, and labor. All agroecosystems are dynamic and are subjected to different levels of management so that the crop arrangements in time and space are continually changing in the face of biological, cultural, socioeconomic, and environmental factors. Such landscape variations determine the degree of spatial and temporal heterogeneity characteristics of agricultural regions, which in turn condition the type of biodiversity present, in ways that may or may not benefit the pest protection of particular agroecosystems. Vegetational designs across appropriate levels of scale comprise a significant form of environmental management. Mechanical modes of environmental management, such as cultivating, mowing, and harvesting, affect the structure and permanence of the habitat and thus the life processes of insects in agroecosystems.
