Rhizoma galangae extracts were obtained using soxhlet extraction method. Control method was adopted to study its repelling action on sitophilus oryzae ephebic. The experiment results show that rhizoma galangae extracts have a strong repelling action on sitophilus oryzae ephebic with a repelling rate of 77% which belongs to Ⅳ level. The ideal repelling time is 36--48 h with a repelling rate of 85%, or of Ⅴ level. In a word, rhizoma galangae is a relatively ideal botanic pesticide.
