| environ. | infestation of crops Invasion of crop by parasites. Among vertebrate animals, many crop pests are mammals, especially in the order of rodents and birds. Among invertebrates, certain species of gastropods and a large number of roundworms from the class of nematodes harm crops. The most varied and numerous species of crop pests are arthropods-insects, arachnids and some species of millipedes and crustaceans. Diseases vary from viral, bacterial, and nutritional to fungal, environmental and non-specific. The FAO has estimated that annual worldwide losses done by plant pests and diseases amount to approximately 20-25% of the potential worldwide yield of food crops | infestación de alimentos y cultivos |
