The larvae of the aphids that injurious to rice have been bred by Zhejiang University in the past day. Once they eat the stems and leaves of this rice, they will die within two days. As a major pest of rice, the locust in our country has an area of ​​10 million hectares per year. For a long time, our country has mainly controlled locusts through chemical pesticides, which not only increased the cost of rice production, but also caused environmental pollution, pesticide residues and other issues. This new achievement of Zhejiang University has a long-term significance for solving the problem of locust infestation. This new strain of transgenic rice resistant to aphids was a joint selection of the Institute of Nuclear Agriculture and Applied Entomology Research Institute of Zhejiang University. In the absence of pesticides, the pests in rice fields as controls were numerous, and the dead leaves were seen everywhere. However, no new symptoms were found in the new strains. Since 1995, scientists from Zhejiang University successfully cooperated with the University of Ottawa, Canada, to transfer the anti-aphid genes into rice plants, and in 1998, they acquired the germplasm resources of Kezidao No. 1 and No. 2 against aphids. Indica rice stably transmits and expresses resistance genes, which are highly resistant to common borer borer, rice borer borer, and vertical leaf curl. After hatchlings, the newly hatched larvae generally die in two days. . On this basis, the scientists and technicians, through crossbreeding, backcrossing, and other methods, were finally selected to develop two stable new strains of early rice infestation, named Huachi 2000B1 and Huachi 2000B6. At the on-site visits and seminars held recently, domestic and foreign experts spoke highly of the research of Zhejiang University and believed that they have already taken the lead in the world. Previously, Kejin had been defined as the safest grade by the Agriculture Genetically Modified Organism Safety Committee of the Ministry of Agriculture and passed food safety certification. The study also showed that Kechangdao had no significant effect on other insects in the paddy field and would not destroy ecological diversity.
