Abstract: Since 1981 we apply fast neutron from an americuurn-beryllium source to radiate the white wax seale's eggs for increasing the white wax production. This paper gives a brief account obtained in expermentation in 1984 in County Emei of Sichuan Province. The experiment showed that an average increase of 22.22%, 29.63% and 21.6% white wax for every 1kg of white wax scale seed after applied the following neutron flux to radiate the white wax seale's eggs: A=1.2×10⁶n/cm², B=3×10⁵n./cm², C=7.62×10⁴n/cm².
