Zhang jubo, a famous agricultural entomologist in China.

Zhang Jubo, formerly known as Ju Bo, was also a rare farmer.1June 900 1892 10 was born in a tenant farmer's family in Gaohe County, Guangdong Province (now Heshan County). His father worked as a farmer for many years and then went abroad to work as a laborer. 1904, 12-year-old Zhang jubo went to school in Japan with his cousin, 1907, and went to Mexico together. 1908 Zhang went to the United States to study in middle school with his father. 19 12 entered the Agricultural College of Ohio State University, first studied agricultural chemistry, then transferred to economic entomology, 19 16 graduated with a bachelor's degree in agriculture; Later, I studied in the graduate school of this school for one year and got a master's degree in entomology.

Zhang Jubo suffered from poverty and backwardness, natural disasters and man-made disasters in rural areas of old China since childhood. When he was studying abroad, he was determined to serve the agriculture of his motherland. Therefore, he took a nickname "Return to Agriculture" and made a famous speech. After he entered the Agricultural College to study entomology, he realized that insects are closely related to agricultural production and pests are a serious threat to crops, so he decided to specialize in the application of entomology and study pest control technology to serve the agricultural production of the motherland. 19 17 After he got his master's degree from Ohio State University, an American company hired him as the manager of the company in China with a high salary, responsible for selling pesticides and other commodities. Zhang jubo declined without hesitation. He later said to people: "I have studied hard for several years, and I am going to serve my country." It is really insulting to ask me to be a comprador. "

Zhang jubo returned to China after finishing his studies. He plans to build a demonstration farm by himself. He went to Wuzhou, Guangxi twice, but the situation was turbulent. 19 18 At the beginning of this year, I applied for the pesticide major of Lingnan University. At that time, Lingnan University was an American-sponsored missionary school, and he found it difficult to realize his long-cherished wish of returning to China in such an environment. 1 1 quit his job, was recommended by a friend to teach at Nanjing Normal University, offered entomology courses, and served as the head of the Department of Pests and Diseases, becoming one of the earliest professors in China universities. He takes this as a starting point, takes teaching as his own responsibility, takes pest control as his goal, and trains key talents of entomology for the country. Jiangsu Insect Bureau was established 1922, and Zhang Jubo was hired as a technician. He presided over the research and popularization of pest control technology, and made contributions to the development of agricultural insect science in China. From 65438-0923, Zhang Jubo taught in Guangdong Public Agricultural College and exchanged professors for one year. After several years' repeated work, he returned to Jiangsu Insect Bureau as director on 1928, and concurrently served as professor of Central University, professor of Agricultural College of Jinling University and director of entomology group. 1932 was entrusted by the Zhejiang provincial government to preside over the work of Zhejiang Insect Bureau. During this period, he established the largest insect specimen room in China at that time and founded the first plant protection periodical Insect and Plant Diseases in China. However, due to many difficulties and troubles in his work, he was forced to leave Zhejiang Insect Bureau on 1936 and return to Guangdong as a professor at Sun Yat-sen University. At the same time, I work part-time in Guangdong Agriculture and Forestry Bureau. 1949, Guangzhou was liberated and People's Republic of China (PRC) was founded. He is full of confidence and passion for the socialist motherland and the new atmosphere of socialist construction, and is determined to work for decades. Unfortunately, 195 1 took his precious life from cancer on May 2, at the age of 59. Before he died, he also encouraged his students to say, "The people's government attaches great importance to the cause of insects. People who study insects have turned over with the liberation of China and will strive to do a good job in the insect industry in new China. " This expresses his childlike innocence.

Zhang jubo is knowledgeable and proficient in English. After coming back from the United States, he studied China literature, so he has a deep understanding of Chinese. His calligraphy is vigorous and powerful, just like a person. He lives a simple life, is modest and prudent, and is not only superior, but also supercilious. He dared to criticize the first director of Jiangsu Insect Bureau, American C. Worth. Originally, he had a chance to go abroad again, but he inadvertently gave the opportunity to others. He said to his colleagues, "The insect problem in China still needs to be solved by ourselves. You have to believe in yourself. " He was dissatisfied with the National Government's invitation to American H.H. Love as the general agricultural adviser of China, believing that it would hurt national self-esteem. Expressing indignation at H.H. Love's "Agricultural China, Industrial America"; Shows the noble national integrity.
