Abstract Industrialized agriculture needs sustainable alternatives to pesticides avoid negative impacts on the environment and human health. Crop diversification is known decrease pest pressure in agricultural crops. Up till now, effects of insect herbivores crop yield are often assumed be equal among cropping systems. We sampled community cabbages five distinct systems characterized by increasing diversity. Using structural equation modelling, we assessed how herbivorous insects influence cabbage through direct consumptive indirect via changes community. The most diverse system synergistically increased abundance richness, whereas other did not differ consistently from each other. Cropping alter effect that have yield, where more do necessarily lead reduced yields. Specific had system‐specific which reflect differences potential for contribute biological control insects. In one with cultivar mixtures, observed yield. This may result a companioning drawing natural enemies away main cultivar, would cultivar. Synthesis applications. Our study shows design characteristics should considered when assessing herbivory As smaller impact systems, synergize biodiversity conservation food production.
