【Abstract】 The toxicity of phosphine and the mortality of adults of Copra mite [Tyrophagus Putrescentiae (Schrank)]are determined in the laboratory at 25 + 1℃ ,RH 75 + 5% with the help of an accurate mite-trap designed by the author. The values of LC50 and LC90 of phosphine used for killing adults of Copra mite are 0. 26mg/l and 1. 2mg/1 respectively.更多还原
