In China, %D.helophoroides% distributed in the regions from the north, Meihekou City(41°41′ N) of Jilin Province to south, Shenzhen City(22°38′ N) of Guangdong Province, and from west, Zhongning county(105°40′ E) of Ningxia Huizu Autonomous Region to east, Meihekou City(125°54′ E) of Jilin Province. The insect distributed widely in Guangdong, Jiangsu, Anhui, Hebi, Henan, Shanxi, Shandong, Ningxia, Shannxi, Beijing, Jilin and Liaoning. The annual mean temperature in the distribution regions was higher than 5.4 ℃, the average temperature in July was above 22.6 ℃, the average temperature in January is higher than -15.2 ℃, and the extreme low temperature was -36.8 ℃. The annual humidity in the distribution regions was above 47.2% and the annual precipitation was above 186.3 mm.展开更多

The transgenic nature of these plants was confirmed by PCR amplification and dot hybridization. The transgenic poplar’s toxicity towards the Anoplophora glabripennis larvae was assessed on two year-old selected plants in laboratory conditions. The results indicated that the transgenic lines BOGA-38 and BOGA-39 were deleterious for A. glabripennis larvae, and BOGA-5、BOGA-31、BOGA-38、BOGA-39 could inhabit the growth of A. glabripennis larvae. BOGA-39 was the most toxic one among the transgenic lines, with (41.18 %) corected mortality rate and 78.90 % growth inhabit rate for the larvae.展开更多
