Octacosanol production and purification with cera chinensis;

Conclusion The acid value and the saponification value of cera chinensis can be determined by the method of changing dissolvent,filtrating and heating.

The catalyst was used to catalyze the hydrogenation of insect-white wax under high pressure.

The white wax scale,Ericerus pela Chavannes,is an invasive alien species and also a new record species in Jilin province.

There has existed “the three reds and three blacks” phenomenon in white wax scales brood insects production for hundreds of years,which brought about an up and down of white wax production.

The ultrastructure of Malpighian tubules of white wax scale, Ericerus pela Chavannes was studied in 1993~ 1994.
