摘要
To produce enough food, we must protect our crops from pests that attack plants. Some of these pests are mysterious small worms called nematodes, wandering through the soil. While most nematodes are beneficial to plants, others can destroy whole crops. The most common weapons against destructive nematodes are also harmful to nature. We need more environmentally friendly tools to control these worms. Tiny spider-like creatures called mites are the nematodes’ arch enemies. Can mites be used to control nematode populations and protect crops? Scientists did experiments on tomato plants in a greenhouse. They added both harmful and helpful nematodes to check the effect of mites. The experiment showed that mites alone, and in combination with the beneficial nematodes, reduced the damage harmful nematodes caused to the plants. Future studies should determine how we can help mites and friendly nematodes to protect our crops and ensure our food supply!
