Cover crops in citrus orchards

The citrus fruit agrosystem is very rich and varied in terms of insect and mite species, both pests and natural enemies. Biological control is one of the cornerstones of Integrated Pest Management. Therefore, conserving and increasing natural enemies is a fundamental objective in citrus fruit cultivation. Biological control by means of conservation can be boosted by choosing the right plant protection products, but also by modifying the environment to encourage the development of these beneficial organisms. Although evergreen citrus trees provide shelter and food all year round to both phytophagous and entomophagous insects, because this is a monoculture, the presence of other plants around the crop can offset the lack of biodiversity that limits the habitat for natural enemies. Traditionally, herbicides have been applied to citrus orchard alleys to keep the ground bare. However, maintaining a cover crop, which may either be planted or grow spontaneously, is an increasingly common practice. This method increases plant diversity in citrus orchards, which in turn leads to a greater diversity of predators and parasites that enable better pest control.
