Farmers created traps for soybean aphids to save their crops. A study by scientists from the University of Illinois is published on the university website.
Soya aphid, which appeared on the American continent in 2000, is today one of the main disasters for agriculture in the country. The ability to reproduce without mating annually several times multiplies the population of these insects.
Scientists at the University of Illinois have studied soybean aphid behavior, population growth over the past 18 years, and have also looked for methods to combat them. The first traps from these insects appeared back in 2001 – ordinary PVC pipes that reach a height of more than 6 m. Inside there are huge fans that direct a solution of water and antifreeze to the insects, which is deadly to insects, but does not harm plants.
Over the past 18 years, more than 30 such systems have been operating non-stop in the United States as research facilities. At the same time, the systems destroyed not only soybean aphids, but also sugar and hemp, which were previously found only in the southern coastal regions of the United States.
After studying aphids and the microbiome associated with these insects, scientists plan to install similar systems in other regions when predicting aphids. In addition, the data obtained from these traps can be used by other scientists in order to increase the amount of knowledge about these pests.
