In the sandy soil along the Great Lakes, there is a poisonous plant, alfalfa. Although it is not cute, it is an important resource for pollinators to settle around the lake. Plant conservation workers at the Chicago Botanic Garden recently produced some 3D printed flowers to attract a weevil to protect the precious plants on the shores of the Great Lakes.
“The weevil is an example of the ongoing deterioration of biological control,†says plant conservation scientist Pati Vitt. “The destruction of the environment has caused the mites to face a crisis of survival, while the weevil that eats the seeds gives the stalks. It’s a devastating blow."
Nature is a delicate balance, and some minor changes in the ecological environment can have unintended consequences. In the 1960s, the country introduced the weevil to control a poisonous cockroach, but then scientists discovered that in addition to the drug cockroaches, the weevil also destroyed the coast of Michigan, Wisconsin, Indiana, and Illinois. And the leaves of Ontario.
To suppress weevils, Vitt and a team at the Harold Washington Library Center Maker Lab in Chicago used 3D printing technology to create plastic flowers that look like wire stalks. Over the past year, they designed 60 plastic flowers and analyzed them. The fragrance of the leaves of the leaves.
Last month, Vitt and her colleague Jeff Gorra tested the scent of the 3D print line leafhoppers in a real line of spider mites. These 3D printed plastic flowers come in three colors, and the bottom is a 20-inch wooden sign that attracts weevils through cotton scented with scented leaves. Although the results were not satisfactory at the beginning, the scientists found some interesting things.
“Other insects are also very interested in them, including those pollinators,†Vitt said. “The ratio of insect visits to real flowers and fake flowers is almost the same, which proves that the smell and visual effects of fake flowers attract insects. ."
It is also the key to about 30 species of pollinator activity, and is also essential for a variety of mammals, birds and insects. For example, Monarch butterfly also chooses valerian habitat during migration. In 1988, due to the destruction of the weevil, the spider mites were classified as endangered species in the United States.
Human intervention in the natural environment often causes serious consequences. Instead of continually remedying it, it is better to pay attention to the ecological balance of nature and protect the environment from the very beginning.
