Abstract

AbstractA survey of the distribution of psocids in major grain storage systems in various provinces of China (Jilin, Liaoning, Gansu, Shanxi, Beijing, Hebei, Henan, Shandong, Anhui, Jiangsu, Zhejiang, Jiangxi, Fujian, Sichuan, Yunnan, Guizhou, Hunan, Guangdong and Guangxi) was conducted. L. entomophila was the most common and widely distributed, followed by L. decolor. L. paeta and Liposcelis mendax were also detected. Ten strains of L. entomophila were evaluated for resistance to phosphine. All strains showed resistance compared with a susceptible reference strain, with resistant factors ranging from 40- to 80-fold. Resistance to phosphine appears to be the major factor determining psocid infestation in grain storage facilities in China.
