To defend plants from attack by parasites, we can take advantage of the action of insect antagonists of parasites. It is no coincidence that some of the best allies we have in the fight against plant parasites in the garden and / or the garden are not supplied by a chemical poison factory but by nature itself; in this case it is about insects. In this regard, we see some examples of spontaneous and ornamental species that attract useful insects in the vegetable garden.
