Description

technical field [0001] The present invention relates to a kind of pesticide preparation for controlling Erythrina chinensis, Background technique [0002] Quadrastichus erythrinae Kim belongs to the family Eulophidae, the subfamily Tetrasticchinae, and the genus Quadrastichus. It is a new species published internationally in 2004. So far, Erythrina has been distributed in Mauritius, Reunion, Hawaii, Singapore, Taiwan, India, Thailand, Philippines, Samoa, Guam and Okinawa. In Taiwan, my country, it was first discovered in Tainan County in 2003. After that, the Erythrina spp. quickly spread to the whole island, and a large number of Erythrina species planted as street trees were severely damaged, and more than 10,000 Erythrina trees were severely damaged. On July 25, 2005, in the mainland of my country, Erythrina was first discovered in the sea pastoral scenic spot in Shenzhen City, Guangdong Province. Now Erythrina has spread to Guangxi, my country and Xiamen City, Fujian P...
