Abstract: objective: We study the effects of soil matrix and soil moisture on growth of Hepialus larvae for perfect artificial breeding Hepialus larvae technology provides the reference. Methods: The experiment used different soil matrix and different soil moisture feeding larvae respectively, and then survey regularly head shell, length, weight,survival rate of the larvae. Results: The different soil matrix have a little influence on growth of larvae. The larvae’s growth and survival rate in the oil matrix contain humus is better than in the pure sand in the earlier stage. The different soil matrix have no significant influence to the larvae’s growth and survival rate in the middle period. there was no significant influence to the larvae’s growth ,but it was significant influence to the survival rate and the pure sand was the best in the later period; The soil moisture content has no significant influence to the larvae’s growth, but it is significant to the larvae’s survival rate and the optimal soil moisture content was 40%-60%.Conclusion: it is recommended that feeding Hepialus larvae can be considered humus soil and sand mixture to be the matrix in the prophase and interim, and use sand matrix to be the matrix in the later period, and control soil moisture content between 40% and 60%.
