Inter-cropping non-Bt-maize with legume crops increases the role of predatory arthropods in naturally regulating herbivorous arthropod pests. Scientists Nickson Otieno et al. recently observed stronger predator-herbivore interactions within maize intercropped than in monoculture fields, both in organic and conventional farming systems. The results are useful in prescribing field practices for sustainable small-scale agriculture from sub-Saharan Africa.
